説明
Dimethylamine hydrochloride is the raw material of organic synthesis, the catalyzer of analysis as an acetylize, and the preparation of azoviolet and dimethylamine aqueous solution. Dimethylamine hydrochloride deoxidation is very capable, and corrodibility is vital, so be usually used in cleaning-type soldering flux. Preparation technology is for slowly splashing into hydrochloric acid in dimethylamine for tradition, and the speed that splashes into is no more than 15 ℃ with temperature, and pH=7-8 is limited. After the reaction finishes, activated carbon decolorizing is added, the filtrate is adjusted to pH=3-4 with hydrochloric acid, decompression is steamed water to the greatest extent, obtaining dimethylamine hydrochloride.
使用
Dimethylamine hydrochloride is a precursor to several industrially significant compounds.
製法・合成法
製造方法
Dimethylamine hydrochloride is obtained from the salt formation of dimethylamine and hydrochloric acid.
純化方法
Crystallise the salt from hot CHCl3 or absolute EtOH. It also recrystallises from MeOH/ether solution. Dry it in a vacuum desiccator over H2SO4, then P2O5. Hygroscopic. [Beilstein 4 IV 132.]
