隨著洗滌及沖洗金屬遮罩的次數增加,沖洗槽中清潔劑的污染率增加。因此,沖洗槽最終被清潔劑污染,且因此需要定期更換沖洗液。然而,由於用作沖洗液之氟化液體亦係昂貴的溶劑,故氟化液體通常係藉由使用蒸餾構件從污染的沖洗液回收,然後再使用。然而,在目前最佳技術中,由於可藉由此類蒸餾構件回收之氟化液體的量非常低,故大部分氟化液體被丟棄。 As the number of times the metal mask is washed and rinsed increases, the contamination rate of the detergent in the rinse tank increases. Therefore, the washing tank is finally contaminated with the cleaning agent, and therefore the washing liquid needs to be changed regularly. However, since the fluorinated liquid used as a rinsing liquid is also an expensive solvent, the fluorinated liquid is usually recovered from the contaminated rinsing liquid by using a distillation member, and then reused. However, in the current best technology, most of the fluorinated liquid is discarded because the amount of fluorinated liquid that can be recovered by such a distillation component is very low.
本揭露提供對被清潔劑污染之氟化液體具有優異的再生效率的氟化液體再生方法,以及使用該方法之再生設備。 The present disclosure provides a fluorinated liquid regeneration method having excellent regeneration efficiency for a fluorinated liquid contaminated with a detergent, and a regeneration apparatus using the same.
根據本揭露之一實施例,提供一種氟化液體再生方法,其包括下列步驟:使被清潔劑污染之氟化液體與水接觸,以使位於上層之水相之清潔劑的濃度小於約80質量%;及將該水接觸後獲得之混合液體分離成位於該上層之水相及位於下層之氟化液體的兩種液體,然後移除該上層之液體並收集該下層之液體;其中該清潔劑係溶解於該氟化液體中之非質子極性溶劑,且該氟化液體係氫氟醚、氫氟烯烴、或其混合物。 According to an embodiment of the present disclosure, there is provided a method for regenerating a fluorinated liquid, which includes the following steps: contacting the fluorinated liquid contaminated by the cleaning agent with water, so that the concentration of the cleaning agent in the upper aqueous phase is less than about 80 mass %; And the mixed liquid obtained after contacting the water is separated into two liquids in the water phase in the upper layer and the fluorinated liquid in the lower layer, and then the liquid in the upper layer is removed and the liquid in the lower layer is collected; wherein the cleaning agent It is an aprotic polar solvent dissolved in the fluorinated liquid, and the fluorinated liquid system is hydrofluoroether, hydrofluoroolefin, or a mixture thereof.
根據本揭露之另一實施例,提供一種使用藉由使用上述再生方法再生之氟化液體作為用於有機EL顯示器製造設備中之部件的沖洗液的方法。 According to another embodiment of the present disclosure, there is provided a method of using a fluorinated liquid regenerated by using the above-mentioned regeneration method as a rinsing liquid for a component in an organic EL display manufacturing apparatus.
根據本揭露之又一實施例,提供一種氟化液體再生設備,其包括:用於使被清潔劑污染之氟化液體與水接觸以使位於上層之水相之清潔劑的濃度小於約80質量%的構件;及用於將該水接觸後獲得之混合液體分離成位於該上層之水相及位於下層之氟化液體的兩種液體,然後移除該上層之液體並收集該下層之液體的構件;其中該清潔劑係溶解於該氟化液體中之非質子極性溶劑,且該氟化液體係氫氟醚、氫氟烯烴、或其混合物。 According to yet another embodiment of the present disclosure, a fluorinated liquid regeneration apparatus is provided, which includes: contacting a fluorinated liquid contaminated with a cleaning agent with water so that the concentration of the cleaning agent in an aqueous phase located on the upper layer is less than about 80 mass % Of the components; and the liquid used to separate the mixed liquid obtained after contacting the water into the liquid phase in the upper layer and the fluorinated liquid in the lower layer, and then remove the liquid in the upper layer and collect the liquid in the lower layer Component; wherein the cleaning agent is an aprotic polar solvent dissolved in the fluorinated liquid, and the fluorinated liquid system is hydrofluoroether, hydrofluoroolefin, or a mixture thereof.

測量純度(%),並以與實例1相同的方式進一步測量所收集之下層液體中之各者的產量(g),不同之處在於水接觸步驟用各種添加量的蒸餾水進行,如下:2.5g(水中之清潔劑的濃度:80.0質量%)、5g(水中之清潔劑的濃度:66.7質量%)、10g(水中之清潔劑的濃度:50.0質量%)、20g(水中之清潔劑的濃度:33.3質量%)、40g(水中之清潔劑的濃度:20.0質量%)、60g(水中之清潔劑的濃度:14.3質量%)、及80g(水中之清潔劑的濃度:11.1質量%)。圖1中顯示基於藉由將測量之純度與測量之產量相乘獲得的值(在下文中有時稱為「再生值」)及基於水中之清潔劑的濃度(質量%)的曲線圖。此處,就圖1而言,較高的再生值意味著較好的氟化液體再生狀態。 The purity (%) was measured, and the yield (g) of each of the collected lower liquids was further measured in the same manner as in Example 1, except that the water contacting step was performed with various added amounts of distilled water, as follows: 2.5 g (Concentration of detergent in water: 80.0% by mass), 5g (Concentration of detergent in water: 66.7% by mass), 10g (Concentration of detergent in water: 50.0% by mass), 20g (Concentration of detergent in water: 33.3% by mass), 40g (concentration of detergent in water: 20.0% by mass), 60g (concentration of detergent in water: 14.3% by mass), and 80g (concentration of detergent in water: 11.1% by mass). FIG. 1 shows a graph based on a value obtained by multiplying the measured purity by the measured yield (hereinafter sometimes referred to as a “regeneration value”) and a concentration (mass%) of a detergent in water. Here, in terms of FIG. 1, a higher regeneration value means a better regeneration state of the fluorinated liquid.
除了使用NOVEC(商品名)7200代替NOVEC(商品名)7100之外,以與實例20相同的方式測量純度及產量。基於此等結果之曲線圖顯示於圖1中。 The purity and yield were measured in the same manner as in Example 20 except that NOVEC (trade name) 7200 was used instead of NOVEC (trade name) 7100. A graph based on these results is shown in FIG. 1.
除了使用VERTREL(商品名)XF代替NOVEC(商品名)7100之外,以與實例20相同的方式測量純度及產量。基於此等結果之曲線圖顯示於圖1中。 The purity and yield were measured in the same manner as in Example 20 except that VERTREL (trade name) XF was used instead of NOVEC (trade name) 7100. A graph based on these results is shown in FIG. 1.
除了使用Asahiklin(商品名)AK-225代替NOVEC(商品名)7100之外,以與實例20相同的方式測量純度及產量。基於此等結果之曲線圖顯示於圖1中。 The purity and yield were measured in the same manner as in Example 20 except that Asahiklin (trade name) AK-225 was used instead of NOVEC (trade name) 7100. A graph based on these results is shown in FIG. 1.
從圖1中之結果可以清楚地看出,能夠確認,對應於本揭露之再生方法之實例20及21的模式中之任一者均比使用氫氟烴及氫氯氟烴之比較例1及2的模式實現了更高的再生值,因此,透過水接觸步驟之再生對除氫氟烴及氫氯氟烴之外的氟化液體具有顯著的作用。具體而言,能夠確認,在實例20及21的模式中之任一者中,當水中之清潔劑的濃度係約30.0質量%至約60.0質量%時,再生值係優異的。這對應於進行水接觸以使位於上層之水相之清潔劑的濃度通常大於約30.0質量%且小於約60.0質量%的情況。 It is clear from the results in FIG. 1 that it can be confirmed that any of the modes corresponding to Examples 20 and 21 of the regeneration method of the present disclosure is better than Comparative Examples 1 and 2 using hydrofluorocarbons and hydrochlorofluorocarbons. The mode 2 achieves a higher regeneration value. Therefore, regeneration through the water contact step has a significant effect on fluorinated liquids other than hydrofluorocarbons and hydrochlorofluorocarbons. Specifically, it was confirmed that, in any of the modes of Examples 20 and 21, when the concentration of the detergent in the water was about 30.0% by mass to about 60.0% by mass, the regeneration value was excellent. This corresponds to a case where the water contact is performed so that the concentration of the detergent in the upper water phase is usually greater than about 30.0 mass% and less than about 60.0 mass%.
將100g Asahklin(商品名)AE-3000(HFE-347pc-f)及10g NMP分別加入樣本瓶中,並搖動30分鐘。向該混合液體中加入40g蒸餾水,並再搖動30分鐘,以產生含有比率為100:40:10之Asahklin(商品名)AE-3000(HFE-347pc-f)、水、及NMP的混合液體。然後,將混合液體轉移至分液漏斗,靜置,直至混合液體分成上層及下層的兩層。收集分成兩層之液體的下層液體,然後將其轉移至在實驗等 級上使用之普通蒸餾器的蒸餾燒瓶中,並在約80℃下開始蒸餾。假設安裝在Liebig冷凝器入口附近的溫度計的溫度下降的時間點係結束時間,則下層液體被分離成再生之氟化液體及待丟棄之殘留物。圖2的右側繪示一系列流程及結果。注意,小於100g之再生之氟化液體的量及殘留物中存在之氟化液體的量的總和被認為係實驗誤差。 100 g of Asahklin (trade name) AE-3000 (HFE-347pc-f) and 10 g of NMP were respectively added to the sample bottle and shaken for 30 minutes. 40 g of distilled water was added to the mixed liquid, and shaken for another 30 minutes to produce a mixed liquid containing Asahklin (trade name) AE-3000 (HFE-347pc-f), water, and NMP in a ratio of 100: 40: 10. Then, the mixed liquid is transferred to a separating funnel, and left to stand until the mixed liquid is separated into two layers of an upper layer and a lower layer. Collect the lower layer of the liquid that is separated into two layers, and then transfer it to the experiment, etc. In the distillation flask of the ordinary still used on the stage, distillation was started at about 80 ° C. Assuming that the temperature drop of the thermometer installed near the entrance of the Liebig condenser is the end time, the lower liquid is separated into a regenerated fluorinated liquid and a residue to be discarded. The right side of Figure 2 shows a series of processes and results. Note that the sum of the amount of regenerated fluorinated liquid less than 100 g and the amount of fluorinated liquid present in the residue is considered to be an experimental error.
將80g Asahklin(商品名)AE-3000(HFE-347pc-f)及20g NMP分別加入樣本瓶中,並搖動30分鐘。此混合液體藉由使用與實例22相同之蒸餾設備及蒸餾條件進行蒸餾,並分離成再生之氟化液體及待丟棄之殘留物。圖2的左側繪示一系列流程及結果。 80 g of Asahklin (trade name) AE-3000 (HFE-347pc-f) and 20 g of NMP were added to the sample bottles, respectively, and shaken for 30 minutes. This mixed liquid was distilled by using the same distillation equipment and distillation conditions as in Example 22, and separated into a regenerated fluorinated liquid and a residue to be discarded. The left side of Figure 2 shows a series of processes and results.
藉由使用校準曲線等推斷出,當含有氟化液體及清潔劑之混合液體在約80℃下蒸餾時,殘留物含有比率為約30%及約70%的清潔劑及氟化液體。在對應於僅使用蒸餾之習知氟化液體再生方法之比較例3中,如圖2之左側所繪示,當混合液體在約80℃下蒸餾時,僅33.3g氟化液體(HFE-347pc-f)能夠再生,且剩餘的46.7g氟化液體不能與清潔劑(NMP)分離,且因此必須丟棄。即,必須丟棄之氟化液體的量係再生之前獲得之混合液體中存在的氟化液體的58.4%。另一方面,在對應於使用蒸餾步驟之本揭露之氟化液體再生方法的實例22中,在透過水接觸步驟以及分離及收集步驟收集之下層液體中,大部分清潔劑 已經被移除,因此,當下層液體在約80℃下蒸餾時,如圖2之右側所繪示,92.6g氟化液體能夠再生,且待丟棄之氟化液體的量能夠保持在非常少量的5.8g。即,必須丟棄之氟化液體的量(該量除了殘留物中之5.8g氟化液體之外亦包括1.6g的誤差)僅為再生之前獲得之混合液體中存在的氟化液體的7.4%。因此,能夠確認,與僅使用蒸餾之習知再生方法相比,使用蒸餾步驟之本揭露之氟化液體再生方法將待丟棄之氟化液體的量減少了87.3%。 It is inferred from the use of a calibration curve and the like that when a mixed liquid containing a fluorinated liquid and a cleaning agent is distilled at about 80 ° C, the residue contains a cleaning agent and a fluorinated liquid at a ratio of about 30% and about 70%. In Comparative Example 3 corresponding to the conventional fluorinated liquid regeneration method using only distillation, as shown on the left side of FIG. 2, when the mixed liquid was distilled at about 80 ° C., only 33.3 g of the fluorinated liquid (HFE-347pc -f) Can be regenerated, and the remaining 46.7 g of fluorinated liquid cannot be separated from the detergent (NMP) and must therefore be discarded. That is, the amount of fluorinated liquid that must be discarded is 58.4% of the fluorinated liquid present in the mixed liquid obtained before regeneration. On the other hand, in Example 22, which corresponds to the fluorinated liquid regeneration method of the present disclosure using a distillation step, most of the cleaner is collected in the lower layer liquid through the water contact step and the separation and collection step. It has been removed, so when the lower liquid is distilled at about 80 ° C, as shown on the right side of Figure 2, 92.6g of fluorinated liquid can be regenerated, and the amount of fluorinated liquid to be discarded can be kept in a very small amount. 5.8g. That is, the amount of fluorinated liquid that must be discarded (this amount includes an error of 1.6 g in addition to 5.8 g of fluorinated liquid in the residue) is only 7.4% of the fluorinated liquid present in the mixed liquid obtained before regeneration. Therefore, it can be confirmed that the fluorinated liquid regeneration method using the present disclosure of the distillation step reduces the amount of fluorinated liquid to be discarded by 87.3% compared with the conventional regeneration method using only distillation.
