Description

Сульфамидопроизводные хинальд .ина получают либО посредством замещени  хлора аминогруппой в соответствующих хлорангидридах сульфокислот хинальдина, либо посредством конденсации соответствующих сульфамидоанилинов с ацетальдегидом в пр исутствии минеральных КИСЛОТ.Sulfamido derivatives of hinald are obtained either by substitution of chlorine with an amino group in the corresponding chlorides of quinaldine sulfonic acids, or by condensation of the corresponding sulfamidoanilines with acetaldehyde in the presence of mineral ACIDS.

Пример. Смесь 100 мл спирта, 50 г сульфаииламида и 7 г хлорной ртути - при пере1мен1ивании - насыщают ацетиленом. После нрекращени  поглощени  ацетилена спирт отгон ют на вод ной бане, остаток раствор ют в Слабой сол ной кислоте , полученный раствор слегка нагревают С животным углем, фильтруют и нейтрализуют содой (проба на лакмус). Выпавший осадок перекристаллизовывают из воды. Выход 6-сзльфамидохинальдина - 40% от теоретического, точка плавлени  214° С.Example. A mixture of 100 ml of alcohol, 50 g of sulfiamylamide and 7 g of chlorine mercury — when changed — is saturated with acetylene. After stopping the absorption of acetylene, the alcohol is distilled off in a water bath, the residue is dissolved in weak hydrochloric acid, the resulting solution is slightly heated with animal charcoal, filtered and neutralized with soda (test for litmus). The precipitate is recrystallized from water. The yield of 6-sflamidochinaldine is 40% of the theoretical, melting point 214 ° C.

доступным И дешевым по сравнению с ацетальдегидом ацетиленом.affordable And cheap compared with acetaldehyde acetylene.

Способ заключаетс  в TOMV что раствор сульфамидопроизводното ароматического амниа в орга«ическом растворителе, к которому добавлены галоидные соли меди или ртути, насыщают ацетиленом на холоду или при слабом нагреваЕин , а полученный сульфамидохинальдин выдел ют обычными методами .The method consists in TOMV that a solution of sulfamide-derived aromatic amnium in an organic solvent, to which copper or mercury halide salts are added, is saturated with acetylene in the cold or with slight heating, and the resulting sulfamidoquinaldine is isolated by conventional methods.

Предмет изобретени Subject invention

Способ получени  сульфампдопроизводных хинальдина, отличающийс  тем, что в раствор сульфамидопроизводного ароматического амина в органическом растворителе пропускают ацетилен в прис тствин галоидных солей меди или ртути в качестве катализаторов и продукт реакции выдел ют известными приемами. Редактор А. Е. НикитскийThe method of producing sulfampdate quinaldine, characterized in that acetylene is passed into the presence of a sulfamide-derived aromatic amine in an organic solvent in the presence of copper or mercury halides as catalysts and the reaction product is isolated by known methods.
