Description
Пример. В трехгорлую колбу, снабженную мещалкой, обратным холодильником, охлаждаемым смесью сухого льда с ацетоном, и газоподвод щей трубкой, помещают 40 лы ацетона, 20 мл воды и пропускают в течение 30 мин 106 г перфторизобутилена при охлаждении льдом и перемешивании. На другой день нагревают до кипени и отгон ют 66 г непрореатировавшего перфторизобутилена. (Процент превраще№ 129653Example. In a three-necked flask equipped with a broom, a reflux condenser, cooled with a mixture of dry ice and acetone, and a gas supply tube, 40 liters of acetone and 20 ml of water are passed and 106 g of perfluoroisobutylene are passed through for 30 minutes while cooling with ice and stirring. The next day, 66 g of unreacted perfluorisobutylene is distilled off to boil. (Percentage conversion number 129653
ни перфторизобутилена в кислоту можно легко увеличить, вз в более разбавленный ацетоном раствор). После высуши-вани хлористым кальцием и отгонки ацетона получают 37 г гексафторизомасл ной кислоты, т. кип. 126-128° (748 мм}, т. пл. 51-52°, мол. вес 196 (криоскопическим методом).neither perfluoroisobutylene to acid can be easily increased by taking the solution into a more dilute with acetone). After drying with calcium chloride and distilling off acetone, 37 g of hexafluoroisobutyric acid are obtained, t. Bale. 126-128 ° (748 mm}, t. Pl. 51-52 °, mol. Weight 196 (cryoscopic method).
Выход гексафторизомасл ной кислоты 95% {в пересчете, на вступивший в реакцию перфторизобутилен). Кислота идентнфицирована превращением в хлорангидрид и далее в анилид. Т. пл. анилида и смешанной , пробы 166-167°.The yield of hexafluoroisobutyric acid is 95% {in terms of the perfluorisobutylene reacted). The acid is identified by conversion to the acid chloride and then to anilide. T. pl. anilide and mixed samples 166-167 °.
Предмет изобретени Subject invention
Способ получени гексафторизомасл ной «И1слоты, отличаюш , и и с тем, что, с целью упрощени реакции и повышени выхода продукта, перфторизобутилен обрабатывают водой в гомогенизирующем инертном органическом растворителе, например, ацетоне.The method of producing hexafluoro-iso-butyric acid, is different, and so that, in order to simplify the reaction and increase the yield of the product, perfluoroisobutylene is treated with water in a homogenizing inert organic solvent, for example, acetone.
