Description
Известны реакции а-хлорметиловых эфиров с непредельными углеводородами , а также применение некоторых продуктов этого взаимодействи в качестве сельскохоз йственных дохимикатов.The reactions of α-chloromethyl esters with unsaturated hydrocarbons are known, as well as the use of some of the products of this interaction as agricultural dokhimikatov.
Однако получаемые в насто щее врем дохимикаты требуют применени деф-ицитного сырь .However, the currently obtained pre-chemicals require the use of a deficitic feedstock.
В предлагаемом способе изопропил-т-хлср-у-фенилпропиловый эфир получают взаимодействием а-хлорметилизопролилового эфира со стиролом в присутствии хлористого цинка в качестве катализатора.In the proposed method, isopropyl-t-hlsr-y-phenylpropyl ether is obtained by reacting α-chloromethyl isoprolyl ether with styrene in the presence of zinc chloride as a catalyst.
Предлагают также примен ть синтезированный препарат в качестве действующего начала дохимиката «Эфиран-79 -80% в сочетании с эмульгатором ОП-10-20% соответственно 4: 1.It is also proposed to use the synthesized preparation as the active principle of the "Efiran-79 -80% dokhimikat" in combination with the emulsifier OP-10-20%, respectively, 4: 1.
Указаиный препарат эффективен против некоторых видов тлей в концентраци х 1-2% и-расходе 1000 л/га. Явл сь менее токсичным, чем известные хими-каты, он более доступен и прост в изготовлении.This drug is effective against some types of aphids at concentrations of 1-2% and a flow rate of 1000 l / ha. Although less toxic than known chemicals, it is more accessible and easier to manufacture.
Пример. В реакционную колбу внос т 43,4 г а-хлорметилизо-пропилового эфира и 50 г четыреххлористого углерода в качестве растворител . К последнему добавл ют 0,651 г (1,5% по а-хлорэфиру). свежерасплавленного хлористого цинка. Затем через капельную воронку , при непрерывном перемешивании, ввод т в течение 1,5 час 4,Q г свежеперегнанкого стирола, растворенного в 50 г четыреххлористого углерода.Example. 43.4 g of a-chloromethyl-isopropyl ether and 50 g of carbon tetrachloride are added to the reaction flask as a solvent. To the latter, 0.651 g (1.5% a-chloro ether) is added. freshly zinc chloride. Then, via continuous addition, with continuous stirring, is introduced for 1.5 hours 4, Q g of fresh distilled styrene dissolved in 50 g of carbon tetrachloride.
Температуру реакционной смеси все врем поддерживают в пределах 15-20. После добавлени всего количества стирола реакционную смесь перемешивают еще 2 час при той же температуре.The temperature of the reaction mixture all the time support within 15-20. After adding the total amount of styrene, the reaction mixture was stirred for another 2 hours at the same temperature.
В дальнейшем реакционную смесь промывают вначале водой, потом 3%-ным водным растворОМ NaOH, затем еще два раза водой и сушат СаСЬ. После отгонки растворител (ССЦ) продукт реакции- маслообразную жидкость желтого цвета в количестве 63,7 г подвергают вакуумной оазгонке и при этом получают следующие фракции:Subsequently, the reaction mixture is washed first with water, then with a 3% aqueous solution of NaOH, then two more times with water and dried with CAC. After distilling off the solvent (SCC), the reaction product is an oily yellow liquid in the amount of 63.7 g is subjected to vacuum oazgonation, and thus the following fractions are obtained:
1-80-121° при 7 мм 3 г; 11-121 - 122° при 7 мм 59,5 г; остаток 1,2 г.1-80-121 ° with 7 mm 3 g; 11-121 - 122 ° with 7 mm 59.5 g; 1.2 g residue
II фракци представл ет собой изопропил i-хлор, - -фенилпропиловый эс|)ир.The second fraction is isopropyl i-chloro, -phenylpropyl es | es).
