Description of the invention (1) Field of the invention The present invention relates to a method for removing volatile components contained in a high-viscosity liquid by using mass transfer equipment, especially a rotary radon packed bed. BACKGROUND OF THE INVENTION The triarylphosphites antioxidant P (0Ar) 3 is an additive commonly used in plastic processing, where Ar represents an aryl group. The traditional method includes two steps: chemical reaction and removal of by-products. The two steps are described separately as follows: Chemical reaction step: ArOH liquid is added to a batch stirred tank and continuously stirred, and then PC13 liquid is added slowly. The reaction is an equilibrium reaction represented by formula (1), formula (2), and formula (3).
ArOH + PC13 ArOPCl2 +HC1 (1)ArOH + PC13 ArOPCl2 + HC1 (1)
ArOH + ArOPCl2 — — (ArO)2PCl +HC1 (2)ArOH + ArOPCl2 — — (ArO) 2PCl + HC1 (2)
ArOH + (ArO)2PCl (ArO)3P +HC1 (3) 式(1)、式(2)、式(3)中之副產品HC1是具可揮發性之氣體, 該HC1氣體使得攪拌反應槽中之黏稠反應液體產生大量泡 沬而易溢出槽體,以致於批式攪拌槽無法連續快速進料, 而導致每批次處理4公噸所需之反應滯留時間要長達1 0小 時以上。 脫除副產物步驟: 在化學反應步驟所產生之副產物HC1必須自反應系統 脫除,使反應破壞平衡而提高抗氧化劑ρ(〇α〇3的產率。傳 本紙張尺度適用中國國家標準(CNS ) A4規格(2ΚΓΧ%7公釐) (請先閱讀背面之注意事項再填寫本頁) 訂 經濟部智慧財產局員工消費合作社印製 58301^ 經濟部智慧財產局員工消費合作社印製 A7 B7五、發明説明(2 ) .統方法脫除HC1是先在常壓下使用情性氣體吹除至酸値爲 3 mgKOH/g,再抽真空及通入惰性氣體脫除至酸値爲0.1 mgKOH/g止。要脫除HC1至一般市場可接受之酸値爲0.1 mgKOH/g之產品,所須耗費之時間長達12小時以上。 1974 年 Herzog 及 Hoppe (USP 3,823,207)揭示了一種製 備三芳基氧膦抗氧化劑的方法,其中將傳統使用攪拌槽之 批次製程,改成以淺盤加隔板所形成之溢流式反應槽之連 續式製程。該溢流隔板所形成反應區的面積與體積之比値 較傳統攪拌槽大。當反應流體通過溢流隔板時,可形成較 大之面積與體積比,有利於反應物接觸並脫除HC1氣體。 另外於反應液中加入不與PC13反應之高沸點溶劑以降低反 應液之黏稠性。藉以上之改善措施,使進料之投料速率得 以增大,雖然反應滯留時間較傳統方法縮短,但是仍然需 要長達1小時,而且所外加之溶劑必須進行蒸餾程序分離, 大幅增加能源消耗量。 發明槪要 本發明的一主要目的在於提供一種利用旋轉塡充床, 從高黏度液體中移除其中所含的揮發成分的方法。 本發明的另一目的,在於提供一種利用旋轉塡充床來 進行一高黏度液體反應物與另一流體的反應,及同時脫除 揮發性副產物來製備一產物的方法。 本發明將高黏度液體進料到旋轉塡充床的一離軸心足 夠遠的位置,利用離軸心較遠處的離心力較大的原理,使 -5 - 本紙張尺度適用中國國家標準(CNS ) A4規格(210X297公釐) (請先閲讀背面之注意事項再填寫本頁) •lifrArOH + (ArO) 2PCl (ArO) 3P + HC1 (3) The by-product HC1 in formula (1), formula (2), and formula (3) is a volatile gas, and the HC1 gas makes the The viscous reaction liquid generates a lot of bubbles and easily overflows the tank, so that the batch stirred tank cannot continuously and quickly feed, resulting in a reaction retention time of more than 10 hours required for processing 4 metric tons per batch. Step of removing by-products: The by-product HC1 produced in the chemical reaction step must be removed from the reaction system, so that the reaction breaks the balance and improves the yield of the antioxidant ρ (〇α〇3. It is said that the paper size applies to Chinese national standards ( CNS) A4 specification (2KΓ ×% 7mm) (Please read the precautions on the back before filling out this page) Order printed by the Intellectual Property Bureau Employee Consumption Cooperative of the Ministry of Economy 58301 ^ Printed by the Intellectual Property Bureau Employee Consumption Cooperative of the Ministry of Economic Affairs A7 B7 Five 2. Description of the invention (2). The conventional method for removing HC1 is to blow off the acid tritium to 3 mgKOH / g with atmospheric gas under normal pressure, and then vacuum and inert gas to remove the acid tritium to 0.1 mgKOH / g. It takes more than 12 hours to remove HC1 to a product that is generally accepted as 0.1 mgKOH / g acidic acid on the market. Herzog and Hoppe (USP 3,823,207) in 1974 revealed a method for preparing triaryl oxygen. The method of phosphine antioxidant, wherein the batch process using the conventional stirring tank is changed to a continuous process of an overflow reaction tank formed by adding a shallow plate and a partition plate. The area of the reaction zone formed by the overflow partition plate and Volume ratio It is larger than the traditional stirring tank. When the reaction fluid passes through the overflow baffle, it can form a larger area to volume ratio, which is conducive to the contact of the reactants and the removal of HC1 gas. In addition, the reaction solution is added with a high boiling point that does not react with PC13 Solvent to reduce the viscosity of the reaction solution. With the above improvement measures, the feed rate can be increased. Although the reaction retention time is shorter than the traditional method, it still takes up to 1 hour, and the additional solvent must be distilled. The program is separated, and the energy consumption is greatly increased. SUMMARY OF THE INVENTION A main object of the present invention is to provide a method for removing a volatile component contained in a high-viscosity liquid by using a rotary radon packed bed. Another object of the present invention, The purpose is to provide a method of using a rotary packed bed to perform a reaction between a highly viscous liquid reactant and another fluid, and to simultaneously remove a volatile by-product to prepare a product.

Description of the invention (4) Lower gas flow of 50%, so that the yield is controlled by traditional processes 80% increase to 90% of the rotary radon filling process. The aforementioned Chinese Patent Publication No. CN 111 6 1 46 A and US Patent No. 6048 5 Π both have a viscosity of only about cp (25), so they are fed from the axis position of the rotary concrete filling bed. Material, the liquid feed can still be subjected to a sufficient rotating gravity field to flow radially through the packed bed. In the method for preparing p (oa〇3) antioxidants described in the foregoing background of the invention, we believe that overcoming the mass transfer limitation of HC1 in viscous reaction solutions is to shorten the manufacturing process, increase the yield of antioxidants ((αα3), reduce the antioxidant The key factor of the oxidizing agent ρ (οα〇3 acid). Therefore, we thought of using a rotating rhenium packed bed to promote the mass transfer rate of HC1 in the viscous reaction solution. At the axis position of the packed bed, the highly viscous ArOH liquid will stay there due to the viscosity and cannot flow through the rotary concrete filling bed radially. In order to solve this problem, we have invented a new type of rotary concrete filling bed, of which A feeding port suitable for the feeding of the high-viscosity liquid is set at a position far enough from the center of the axis to generate sufficient centrifugal force to cause the high-viscosity liquid to flow radially through the rotary packed bed. With this consideration Mode, we also propose methods to remove volatile components from high viscosity liquids, such as removing unreacted polyisocyanate monomers from high viscosity polyurethanes, and Tris nonylphenol phosphite removes hydrogen chloride from antioxidants. A method for removing volatile components from high-viscosity liquids using a rotary hydrazone packed bed completed in accordance with the present invention includes the following steps: a) a High-viscosity liquid is introduced into a rotating concrete filling bed which is rotating around an axis. The rotating concrete filling bed is located in a housing. The rotating concrete filling bed (please read the precautions on the back before filling this page)
