| Use | Dimethylamine hydrochloride is a raw material for organic synthesis, and is also used as a catalyst for acetylation analysis and preparation of magnesium reagent and dimethylamine aqueous solution. Dimethylamine hydrochloride has strong deoxidation ability and strong corrosiveness, so it is often used for cleaning flux. high activity, can reduce the surface tension, so that the solder and the metal to be welded wetting each other, enhance the ability of soldering; organic analysis reagents, acetylation analysis as a catalyst, also used in organic synthesis and preparation of dimethylamine aqueous solution. Dimethylamine hydrochloride is a raw material for organic synthesis, and is also used as a catalyst and magnesium reagent for acetylation analysis. Used as a catalyst for acetylation analysis, and also used in organic synthesis and preparation of dimethylamine aqueous solution Used as a raw material for pharmaceuticals |

Reproductive toxicity: mice transabdominal TDLo: female pregnancy 1-17 days after pregnancy: 3825mg/kg; Affect the mortality rate after embryo implantation. Tumor data: mouse oral TDLo:12 gm/kg/Y-C, RTECS standard for tumor, lung, chest or respiratory-bronchial cancer liver-tumor. |
| Production method | It is obtained by salting dimethylamine and hydrochloric acid. Slowly drip hydrochloric acid into dimethylamine, the dosage of hydrochloric acid 30% is about 1.1 times that of 40% dimethylamine, and the drip speed is limited to the temperature not exceeding 15 ℃ and pH = 7-8. After the reaction, add activated carbon to decolorize, filter, adjust the filtrate to pH = 3-4 with hydrochloric acid, and evaporate water under reduced pressure to the end to obtain dimethylamine hydrochloride. |
