Description

Предлагаемый способ получени  галоидалкилов заключаетс  в действии алкильныхэфиров ароматических сульфатов на водные растворы галоидоводородных солей .щелочныхThe proposed method of producing alkyl halides consists in the action of alkyl ethers of aromatic sulfates on aqueous solutions of alkali hydrogen halides.

Ллк4-Ме /.502 Ме-|-|-/ лк X, где/ какой-нибудь ароматический радикал , , Cio//7 и т. д.; , QT/s, , и другие -жирные алкильные раДикалы; Me металлы первой группы, а , бром или иод. Нужные дл  реакции эфиры ароматических сульфокислот получаютс  с хорошими .выходами по способу Hinsberga (В. 23, 29, 62, Япп. 265.178). Пример 1. 186 I метилового эфира паратолуолсульфоновой кислоты смешиваютс  в колбе с водным концентрированным раствором 166 Z йодистого кали  (1 :1). Полученна  смесь нагреваетс  на вод ной бане, с холодильником. Выдел ющийс  при реакции йодистый метил отгон етс , сушитс  и обь;ч . ным образом ректифицируетс . Выход 110-120 г., metals, when heated. The reaction proceeds according to the following scheme: R. Llk4-Me /.502 Me - | - | - / lk X, where / is some aromatic radical,, Cio // 7, etc .; , QT / s,, and other-fatty alkyl radicals; Me metals of the first group, a, bromine or iodine. The aromatic sulfonic esters required for the reaction are obtained with good outputs according to the Hinsberga method (V. 23, 29, 62, Japp. 265.178). Example 1. 186 I of para-toluenesulfonic acid methyl ester are mixed in a flask with an aqueous concentrated solution of 166 Z of potassium iodide (1: 1). The resulting mixture is heated in a water bath, with a refrigerator. The methyl iodide liberated by the reaction is distilled off, dried and the volume; This is rectified. Output 110-120 g.

КИМ же образом, как в примере 1 обрабатываютс  йодистым калием. Полученный йодистый этил сушитс  и ректифицируетс . Выход 100-110 г.The CMM is treated in the same manner as in Example 1 with potassium iodide. The resulting ethyl iodide is dried and rectified. Exit 100-110 g.

Пример 3. 200 г этилового эфира паратолуолсульфокислоты смешиваютс  с крепким водным раствором бромистого кали  (1:2). Нагреваютс  на вод ной бане с холодильником; получающийс  бромистый этил отгон етс , отдел етс  от воды, сушитс  сульфатом и фракционируетс . Выход около 75 г.Example 3. 200 g of p-toluenesulfonic acid ethyl ester are mixed with a strong aqueous solution of potassium bromide (1: 2). Heated in a water bath with a fridge; the resulting ethyl bromide is distilled off, separated from water, dried with sulphate and fractionated. Output about 75 g.

Пример 4. 175 г метилового эфира бензолсульфоно1 ой кислоты смешиваютс  с водным концентрированным раствором 186 г йодистого натра (). Полученна  смесь обрабатываетс , как в примере . Выход ПО-120 г йодистого метила.EXAMPLE 4 175 g of methyl benzene sulfonic acid ester is mixed with an aqueous concentrated solution of 186 g of sodium iodide (). The resulting mixture is processed as in the example. The output is 120 g of methyl iodide.
