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.

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

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.
