Description
Способ получени перекиси третичного бутила взаимодействием изобутилена, серной кислоты и перекиси водорода при -20-0°С с последующим отделением сло конечного продукта и промывкой его раствором щелочи и водой (врем реакции более 24 час} известен .The method of producing tertiary butyl peroxide by reacting isobutylene, sulfuric acid and hydrogen peroxide at -20-0 ° C, followed by separating the layer of the final product and washing it with an alkali solution and water (reaction time more than 24 hours} is known.
С целью повышени выхода целевого продукта и его качества, а также ускорени процесса , предлагаетс вести указанный процесс при 30 -50°С и давлении 0,03-1 атм.In order to increase the yield of the target product and its quality, as well as accelerate the process, it is proposed to conduct this process at 30-50 ° C and a pressure of 0.03-1 atm.
Пример. В герметичный реактор с мешалкой , барботером, термогильзой и паровод ной рубащкой загружают 60-65%-ную серную кислоту, в течение 1-2 час при интенсивном перемешивании подают изобутилен (0,95-0,98 моль на 1 моль HsSO) при температуре внутри реактора 30-50°С и повышенном давлении 0,03-1 атм, после чего реакционную массу перемешивают еще 10- 30 мин, а затем добавл ют в нее 30%-ную перекись водорода (0,45-0,5 моль на 1 моль изобутилена) при той же температуре и перемешивают ее еще 1-2 час. Далее отдел ют от массы отслоившуюс перекись третичного бутила, промывают ее водой до нейтральной реакции и сушат,Example. 60-65% sulfuric acid is loaded into a pressurized reactor with a stirrer, a bubbler, a thermowell, and a steam bath, and isobutylene (0.95-0.98 mol per 1 mole of HsSO) is fed for 1-2 hours with vigorous stirring at a temperature of inside the reactor, 30-50 ° C and an elevated pressure of 0.03-1 atm, after which the reaction mass is stirred for another 10-30 minutes, and then 30% hydrogen peroxide (0.45-0.5 mol per 1 mol of isobutylene) at the same temperature and stirred for another 1-2 hours. The tertiary butyl peroxide is then separated from the mass, washed with water until neutral and dried,
кись третичного оутила, получаема в опытах, содержит, по данным йодометрического титровани , менее 2% гидроперекиси. 3 , Предмет изобретени , Способ получени перекиси третичного бутила взаимодействием изобутилена, серной кислоты и перекиси водорода с последующим 5 4 отделением сло конечного продукта н промывкой водой, отличающийс тем, что, с целью увеличени выхода целевого продукта и ускорени процесса, последний ведут при 30-50°С и давлении 0,03-1 атм.The tertiary outili obtained in the experiments, according to iodometric titration, contains less than 2% hydroperoxide. 3, the subject of the invention, a method for producing tertiary butyl peroxide by reacting isobutylene, sulfuric acid and hydrogen peroxide followed by 5 to 4 separating the final product layer and washing with water, characterized in that, in order to increase the yield of the target product and accelerate the process, the latter is carried out at 30 50 ° C and a pressure of 0.03-1 atm.
