Description

Пример. В круглодонной нолбе раствор ют 15,4 Z м-хлорацетофенона в 60 c« 70Vo-ro винного спирта, добавл ют 15 г уротропина и нагревают смесь с обратным холодильником на вод ной бане 5-6 часов. Продукт реакции выливают в воду, и выделившийс  масл нистый СЛОЙ экстрагируют эфиромExample. 15.4 Z of m-chloroacetophenone is dissolved in 60-c "70 Vo-ro wine alcohol in a round-bottomed nolba, 15 g of hexamine is added and the mixture is heated under reflux in a water bath for 5-6 hours. The reaction product is poured into water, and the oily LOOKY separated out is extracted with ether.

ИЛИ бензолом. Эфирный экстракт, по отгонке эфира, разгон ют в вакууме. Выход фенилглиоксал  с точкой кипени  108-110°-10 г, что составл ет 76Vo от теории.OR benzene. The ether extract, after distilling off the ether, is distilled in vacuo. The yield of phenylglyoxal with a boiling point of 108-110 ° -10 g, which is 76Vo from theory.

Полученные 10 г фенилглиоксала заливают в С1-образный сосуд, одно колено которого заполнено никелевым каталиводорода , назатором , пропускают ток The resulting 10 g of phenylglyoxal is poured into a C1-shaped vessel, one knee of which is filled with a nickel cataligorod, nasator, a current is passed

Or образовавшегос  в небольшом количестве фенилэтилового спирта освобождаютс , обрабатыва  фенилацетальдегид безводным хлористым кальцием.Or, a small amount of phenylethyl alcohol is released by treating the phenylacetaldehyde with anhydrous calcium chloride.

Предмет изобретенилThe subject invented

Способ получени  фенилацетзльдегида из СО-хлорацетофенона, отличаюиииТс  тем, что tfj-хлорацетофенок нагреванием с уротропином превращают в фенилглмоксаль с последующим восстановлением фенилглиоксал  действи-гм водорода в присутствии никелевого хатализатора .The method for producing phenylacetic aldehyde from CO-chloroacetophenone differs in that tfj-chloroacetophenic is converted into phenylglymoxal by heating with urotropin followed by reduction of phenylglyoxal action-gm hydrogen in the presence of a nickel catalyst.
