Properties and stability
Use and store according to specifications, no decomposition will occur, and avoid contact with oxides
Storage method
Save sealed and placed in a ventilated, dry environment
Synthesis method
It is obtained by forming a salt between dimethylamine and hydrochloric acid. Slowly drip hydrochloric acid into dimethylamine. The dosage of 30% hydrochloric acid is about 1.1 times that of 40% dimethylamine. The dripping speed is limited to a temperature of no more than 15°C and a pH of 7-8. After the reaction is completed, add activated carbon for decolorization and filter. The filtrate is adjusted to pH=3-4 with hydrochloric acid, and the water is evaporated under reduced pressure to obtain dimethylamine hydrochloride.
Purpose
1. Dimethylamine hydrochloride is a raw material for organic synthesis and is also used as a catalyst and magnesium reagent for acetylation analysis.
2. is used as a catalyst in acetylation analysis, and is also used in organic synthesis and the preparation of dimethylamine aqueous solution
3. Used as pharmaceutical raw materials
