Description
конце в вакууме водоструйного насоса). Остаток после обработки водой закристаллизовываетс в виде гранул, которые отфильтровывают , промывают водой, 5-10%-ной уксусной кислотой, затем снова водой. После кристаллизации из водной уксусной кислоты получают 9,75-10,7 г (50-55%) очищенного эфира 4-диметиламиносалициловой кислоты с т. пл. 85-86°С.end of a water jet pump vacuum). The residue after treatment with water is crystallized in the form of granules, which are filtered, washed with water, 5-10% acetic acid, then again with water. After crystallization from aqueous acetic acid, 9.75-10.7 g (50-55%) of purified 4-dimethylaminosalicylic acid ester are obtained with a mp. 85-86 ° C.
