Description
Перекиси диацила, в частности перекись стеароила, наход т применение в качестве инициатора нри полимеризации.Diacyl peroxide, in particular stearoyl peroxide, is used as an initiator for polymerization.
Известен способ получени перекиси диац11ла путе.м взаимодействи хлорангид.рида кислоты с перекисью водорода в присутствии щелочи ири температуре от О до -5°С в течение 30 лшн.A known method of producing diacetal peroxide by reacting acid chloride with hydrogen peroxide in the presence of an alkali and a temperature from 0 to -5 ° C for 30 hours.
Предложенный способ отличаетс тем, что процесс провод т в среде низкокнн щего растворител , например диэтилового или петролейного эфира. Это сиособствует увеличениго выхода целевого продукта.The proposed method is characterized in that the process is carried out in a low-solvent solvent, such as diethyl or petroleum ether. This contributes to an increase in the yield of the target product.
Пример 1. В реактор с мешалкой загружают 27|)/о-ную перекись водорода и едкое кали , затем при подаетс при перемеиигвании раствор стеароилхлорида в диэтиловом эфире. Перекись водорода, едкое кали, етсаронлхлорид берут в мол рно.м отношении 2:1:1. Серный эфир дл растворени хлорида берут в СООТНОН1СНИИ 0,5 л на 1 моль хлораигидрида. После смегиени реагентов реакционную массу перемешивают 30-40 мин и добав.т ют е:це 1-2 л эфира иа 1 моль исходного хлорида.Example 1. 27 |) / o-peroxide of hydrogen peroxide and caustic potassium are loaded into a reactor with a stirrer, then a solution of stearoyl chloride in diethyl ether is fed during stirring. Hydrogen peroxide, caustic potash, etaronyl chloride are taken in a molar ratio of 2: 1: 1. Sulfuric ether for dissolving the chloride is taken in COTONH1SNII 0.5 l per 1 mol of chlorohydride. After samgienic reagents, the reaction mass is stirred for 30–40 minutes and a mixture of 1-2 liters of ether and 1 mol of the starting chloride is added.
Водный слоГ сливают, а раствор нерекнси в эфире промывают небольшими порци ми воды до неГ1тралыю11 реакции. Затем сериыи эфир отгон ют при комнатной температуре нод вакуумом и остаг.шуюс в остатке переKiiCb стеароила сушат па воз.чухе.The aqueous layer is drained off, and the nerexne solution in ether is washed with small portions of water until the reaction is complete. Then, the ether series is distilled off at room temperature by a vacuum and the residue in the residue of KiiCb stearoyl is dried on the air.
