Preparation |
by heavy chromate salt in the presence of sodium content and deal with N1,N1-dimethylbenzene-1,4-diamine, transforming it into the content and sulfonic acid, this product then through heavy chromate salt and O-Methylaniline processing, into a unique of sulfur acid amine generation, then use heavy chromate salt and copper sulfate closed loop and oxidation, Finally,?the?zinc chloride?salt?precipitation |
Manufacturing Process |
As taken from US Patent 416,055 (probably the oldest patent on the manufacture of a currently-used drug): In carrying out this process about 6 pbw of dimethyl-p-phenylenediamine was dissolved in about 18 pbw of hydrochloric acid of about 1.16 specific gravity and then a solution of about 3.8 pbw of nitrite of soda in about 6 pbw of water was gradually added. The hydrochlorate of nitroso-dimethylaniline thus produced in the well-known manner is then submitted to the reducing action of zinc-dust by adding, first about 30 pbw of hydrochloric acid of about 1.16 specific gravity and then (in small portions at a time) about 10 pbw of zinc-dust as is well understood by chemists. The solution of hydrochlorate of paramido-dimethylaniline thus obtained is afterwards diluted with about 250 pbw of water and then the uncombined hydrochloric acid contained in the solution is, if any, neutralized by the addition of an alkali. There are then added about 16 pbw of sulfate of alumina and about 13 pbw of thiosulfate of sodium, (hyposulfite of soda) and immediately afterwards a solution of about 5 pbw of bichromate of potash in about 60 pbw of water is quickly run in. |
