Пример. В 5-литровую колбу с мешалкой и обратным холодильником загружают 2,5 литра сухого бензола, 92 г распыленного металлического тчатри и 89 г этилового эфира амидсалицилуксусной кислоты.Example. A 5-liter flask with a stirrer and reflux condenser is charged with 2.5 liters of dry benzene, 92 g of a sprayed metallic metal and 89 g of ethyl amide salicylacetate.
