Description
(54) СПОСОБ ПОЛУЧЕНИЯ НАСЬЩЕННЬК АЛЬДЕГИДОВ С.- С,(54) METHOD FOR GETTING OF ASTED ALDEHYDES S.- S,
II
Изобретение относитс к усовершекртвованному способу получени насыщенных альдегидов Cg , которые используют как полупродукты дл производства пластмасс, клеев, лаков.The invention relates to an improved method for producing saturated Cg aldehydes, which are used as intermediates for the production of plastics, adhesives, varnishes.
Известен способ насыщенных альдегидов Сд- Cf окислением соответствующих алкилбромидов диметилсульфоксидом СДМСО) превращени галоидных алкилов в соответствуювще тозилаты-эфиры толуолсульфокислоты с последующим окислешгем последних. Температура окислени составл ет бЬ-80 С. Выход целевого продукта не превышает 70% t1The known method of saturated aldehydes Cd-Cf by oxidation of the corresponding alkyl bromides with dimethyl sulfoxide (SDMSO) converts the alkyl halides to the corresponding tosylates esters of toluenesulfonic acid, followed by oxidation of the latter. The oxidation temperature is bb-80 ° C. The yield of the target product does not exceed 70% t1
Недостатком данного способа в л етс усложнение способа за счет превращени галогенидов в тозила-пл, это превращение ведет к потере исходного реагента, при получении тозилатов используют толизаты серебра, а это св зано с использовайием дефицитных и дорогосто щих препаратов серебра. Кроме этого, способ отличвThe disadvantage of this method is the complication of the method due to the conversion of halides to tosyl-pl, this conversion leads to the loss of the initial reagent, while tolysates of silver are used in the preparation of tosylates, and this is due to the use of scarce and expensive silver preparations. In addition, the method of distinguishing

,гтс относительно низким выходом целевого продукта., hts relatively low yield of the target product.
Цель изобретени - увеличение выхода целевого продуктами упрощение процесса.The purpose of the invention is to increase the yield of the target products to simplify the process.
Поставленна цель достигаетс тем, что согласно способу получени насыщенных альдегидов Q. - С окислением соответствующего алкилбромида диметилсульфоксидом при температуре This goal is achieved by the fact that according to the method of obtaining saturated aldehydes Q. - With the oxidation of the corresponding alkyl bromide with dimethyl sulfoxide at a temperature
10 60-80°С процесс ведут в присутствии хлорида или бромида алюмини при мольном соотношении соответствующего алкилбромида и хлорида или бромида алюмини , равном 1:1.10 60-80 ° C. The process is carried out in the presence of aluminum chloride or aluminum bromide with a molar ratio of the corresponding alkyl bromide and aluminum chloride or aluminum bromide, equal to 1: 1.

Процесс осуществл ют на вод ной бане в течение 5ч. После завершени процесса в реакционную смесь добавл ют воду, тщательно перемешивают и отдел ют верхний слой.The process is carried out in a water bath for 5 hours. After the process is complete, water is added to the reaction mixture, mixed thoroughly, and the upper layer is separated.
мm
Предлагаемый способ позвол ет по-; высить выход целевого продукта до 92% против 70% в ивзестиом способе а также аест процесс в одну стадию.The proposed method allows po; to increase the yield of the target product to 92% against 70% in the test method and also the process in one stage.
