Description

В основиом авторском свйдетельст(ве № 46927 описан снособ фенилировани  и толировани  нафтил-амин-1-суль1ФОКИСЛОТЫ-8 действием анилина при нагревании и нормальном давлении при проведении .реакции в отсутствии кж;ларода или других окисл ющих газов .Basically, the author's article (Ve. No. 46927 describes the procedure for phenylation and naphthyl-amine-1-sulfonic acid oxidation-8 treatment by the action of aniline under heating and normal pressure when conducting a reaction in the absence of gf;

Указанный способ, да1ва  продукт, чистый от смол, не обеопечивает протекани  реакции фенилировани  и толировани  перикислоты нацело, из-за чего фенил (толил)-перикислота, выделенна  без кристаллизации ее солей, даегг краситель, отличающийс  от стандарта .This method, the pure resin product, does not guarantee the reaction of phenylation and peri-acid tolation completely, due to which the phenyl (tolyl) pericaric acid, isolated without crystallization of its salts, is a dye that differs from the standard.

Авторами установлено, что, если при фенилировании (толировании) перикислоты в указанных услови х будет Добавлено некоторое количество серной кислоты, реакци  проходит -нацело . Продукт, полученный при этом, дает краситель соодаветстаующейго стандарту качества. Серна  кислота вз та потому, что она дает меньщую, по сравнению с сол ной кислотой, коррозию аппарата.The authors found that if a certain amount of sulfuric acid was added during the phenylation (tolirovanie) pericyclic acid in the specified conditions, the reaction is completely. The product obtained at the same time, gives the dye soodavatsuyuschego quality standard. Sulfuric acid is taken because it gives less, in comparison with hydrochloric acid, corrosion of the apparatus.

Пример. 850 кг анилина (или соответствующее количество п-толуидина ) подогревают до 40-60° и загружают 44,4 кг моногидрата, после чего внос т 335 кг нафтиламин-1-сульфокислоты-8 , содержащей кристаллизационную воду. Массу нагревают до 160° и при этом пространство над массой заполн етс  вод ными парами.. Реакционную массу выдерживают лри 160° в течение 8 часов. По окончании реакции отгон ют вод ным паром (толу и дин), в присутствии магнезита , после чего подкислением серной кислоты выдел ют фенил (толил)-перикислоту .Example. 850 kg of aniline (or the corresponding amount of p-toluidine) is heated to 40-60 ° and 44.4 kg of monohydrate are charged, after which 335 kg of naphthylamine-1-sulfonic acid-8 containing crystallization water are introduced. The mass is heated to 160 ° and the space above the mass is filled with water vapor .. The reaction mass is held at 160 ° for 8 hours. At the end of the reaction, it is distilled off with steam (tolu and dine), in the presence of magnesite, after which the phenyl (tolyl) -peric acid is isolated by acidification of sulfuric acid.

Предмет изобретени .The subject matter of the invention.

Прием выполнени  способа фенилировани  и толировани  нафтил-амин1 -сульфокислоты-8 по авторскому свидетельству № 46927, отличающийс  тем, что реакцию провод т в присутствии серной кислоты, с целью повыщени  чистоты получаемого продукта .;Acceptance of the method of phenylation and interpretation of naphthyl-amino 1-sulfonic acid-8 according to the author's certificate No. 46927, characterized in that the reaction is carried out in the presence of sulfuric acid in order to increase the purity of the product obtained;
