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
