Description
Известна реакци теломеризацин, позвол юща получать самые разнообразные органические соединени , однако она не получила промышленного осуществлени в св зи с р дом технологических трудностей.The known reaction of telomerizacin, which makes it possible to obtain a wide variety of organic compounds, however, it has not been commercialized due to a number of technological difficulties.
Предметом изобретени вл етс оригинальный способ проведени реакции теломеризации этилена с четыреххлористым углеродом, пригодный дл реализации в промышле)ности . С целью устранени возможности взрывов, процесс провод т в непрерывно действующем трубчатом реакторе, который через сборник продукта сообщаетс с атмосферой или с газгольдером через дроссельный вентиль и сборник.The subject of the invention is an original method of carrying out the reaction of telomerization of ethylene with carbon tetrachloride, suitable for implementation in the industry. In order to eliminate the possibility of explosions, the process is carried out in a continuously operating tubular reactor, which is in communication with the atmosphere through a product collector or with a gasholder through a throttle valve and a collection vessel.
В качестве инициатора теломерлзации примен етс азодинитрил диизомасл ной кислоть или перекись бензоила, что позвол ет снизить температуру реакции до 75-80° или облучениз ультрафиолетовым светом , дающее возможность вести процесс при температуре 30-40°.Azodinitrile diisobutyric acid or benzoyl peroxide is used as the telomerlization initiator, which allows the reaction temperature to be reduced to 75-80 ° or irradiated with ultraviolet light, making it possible to conduct the process at a temperature of 30-40 °.
Пример 1. Взаимодействие этилена и четырех.хлористого углерода в змеевиковом трубчатом реакторе проточного типа.Example 1. The interaction of ethylene and carbon tetrachloride in the coiled tubular flow type reactor.
В нижнюю часть обогреваемого змеевикового трубчатого реакто К1, изготовленного из нержавеющей стали ЭЯ1Т, с внутренним диаметром 14 мм и толщиной стенок 2 мм подают с помощью насоса раствор перекиси бензоила или азодинитрилт.иизомасл ной кислоты в четыреххлористом углероде. Одновременно в jieaKTop подаетс сжатый этилен.To the bottom of the heated coil tubular reactor K1, made of stainless steel EYa1T, with an inner diameter of 14 mm and a wall thickness of 2 mm, a solution of benzoyl peroxide or azodinitrite and isobutyric acid in carbon tetrachloride is pumped. At the same time, compressed ethylene is fed into the jieaKTop.
При реакции взаимодействи этилена и четыреххлористого углерода в присутствии перекиси бензои.ча (концентраци в ССЦ - 0,5%, температура в бане реактора 110° и давление в реакторе 200 атм) получают смесь, содержащую около 64% непрореагировавшего СС. около 4% тетрахлорпропановой фракции, около 13% тетрахлорпентановой фракции , около 12% тетрахлоргептановой фракции и около 7% остатка.In the reaction between ethylene and carbon tetrachloride in the presence of benzoic peroxide (concentration in the SST is 0.5%, the temperature in the bath of the reactor is 110 ° and the pressure in the reactor is 200 atm) a mixture containing about 64% of unreacted SS is obtained. about 4% tetrachloropropane fraction, about 13% tetrachloropentane fraction, about 12% tetrachloroheptane fraction, and about 7% of the residue.
При реакции этилена и четыреххлористого углерода в присутствии азодш-пггрила диизомасл ной кислоты (концентраци в CCli 0,6%. температура в бане 80-85° и давление 180 атм получают смесь, содержащую около 48% непрореагировавшего ecu, около 22% тетрахлорпентаBy the reaction of ethylene and carbon tetrachloride in the presence of azodi-pggryl diisobutyric acid (CCli concentration 0.6%. The temperature in the bath is 80-85 ° and the pressure 180 atm. A mixture is obtained containing about 48% unreacted ecu
