Description
Известен снособ получени (3-металлилбромида бромированием изобутилена в присутствии азота (носител брома) при температуре 300-350° С, процесс ведут при 100%-ном избытке изобутилена. Выход продукта 50%.A known method of producing (3-metal bromide by brominating isobutylene in the presence of nitrogen (bromine carrier) at a temperature of 300-350 ° C. The process is carried out with a 100% excess of isobutylene. Product yield 50%.
Предложенный способ отличаетс от известного тем, что на изобутилен действуют хлористым бромом при температуре 150° С, врем реакции час, что упрощает процесс. Ведение процесса предложенным способом позвол ет снизить температуру реакции и исключить операцию отделени азота от изобутилена, который беретс в избытке.The proposed method differs from the well-known fact that isobutylene is acted upon with bromine chloride at a temperature of 150 ° C, the reaction time is one hour, which simplifies the process. Conducting the process with the proposed method allows reducing the reaction temperature and eliminating the operation of separating nitrogen from isobutylene, which is taken in excess.
;П р и м е р 1. В реактор хлористого брома подают 80 г/час газ1 образного брома и li,2 мл/час хлора. Температура реактора 60 С. Образовавшийс хлористый бром поступает в реактор галоидировани , в который подаетс технический изобутилен со скоростью 23,4 мл/час. Температура в реакторе 150° С. При длительности опыта 1 час. получают 130е продукта.; EXAMPLE 1. 80 g / h of gaseous bromine and li, 2 ml / h of chlorine are fed to the reactor of bromine chloride. The temperature of the reactor is 60 C. The resulting bromine chloride enters the halogenation reactor, into which technical isobutylene is fed at a rate of 23.4 ml / hour. The temperature in the reactor is 150 ° C. With a test duration of 1 hour. get 130e product.
Разгонкой выдел ют следующие основные галоидпроизводные (в г):The following halide derivatives are isolated by distillation (in g):

Остальное - промежуточные фракции, полигалоидпроизводные и потери.The rest is intermediate fractions, polyhalo derivatives and losses.
П р и м е р. 2. В реактор хлористого брома подают со скоростью 62,5 г/час газообразного орома и 8,5 мл/час хлора. Хлористый бром смещивают с 26,3 мл/час технического изобутилена . Температура опыта аналогична услови м примера 1.PRI me R. 2. The bromine chloride reactor is fed at a rate of 62.5 g / hour of orom gas and 8.5 ml / hour of chlorine. Bromine chloride is shifted from 26.3 ml / h of technical isobutylene. The temperature of the experiment is similar to the conditions of example 1.
Например, пропускают 47 г брома, 6,35 мл хлора и 19,7 мл изобутнлена. Получают 85,1 г галоидопроизводных. Разгонкой выдел ют 33 г р-металлилбромида, остальна часть состоит из галоидпроизводных, указанных в примере 1. Выход р-металлилбромида 41,5% на вз тый бром.For example, 47 g of bromine, 6.35 ml of chlorine and 19.7 ml of isobutyl chloride are passed. 85.1 g of halogen derivatives are obtained. 33 g of p-metal bromide are isolated by distillation, the remainder consists of the halogen derivatives indicated in Example 1. The yield of p-metal bromide is 41.5% on taken from bromine.
Предмет изобретени Subject invention
Способ получени (3-металлилбро.мида бромированием изобутилена при повышенной температуре, отличающийс тем, что, с целью упрощени процесса, в качестве бромирующего агента используют хлористый бром и процесс ведут при температуре 150° С.The method of obtaining (3-metalbromide. Bromination of isobutylene at elevated temperature, characterized in that, in order to simplify the process, bromine chloride is used as the brominating agent and the process is carried out at a temperature of 150 ° C.
