| titleOfInvention | 2-dimethylaminoethyl chloride hydrochloride synthesis technology |
| abstract | The invention discloses a 2-dimethylaminoethyl chloride hydrochloride synthesis technology. The technology comprises that dimethylethanolamine as a raw material and thionyl chloride directly undergo a chlorination reaction in an ice water bath under control of a temperature in a range of 8-18 DEG C, anhydrous ethanol is added into the reaction product, the mixture undergoes a reflux reaction for 2h, and the reaction product is filtered and dried so that a finished product is obtained. The 2-dimethylaminoethyl chloride hydrochloride synthesis technology has the advantages that 1, the product is free of recrystallization and has a high yield, good quality and a low cost, 2, reaction conditions are mild and are convenient for operation, 3, product purity is high and inorganic salt content is less than 0.5%, and 4, three wastes are reduced, hydrogen chloride and sulfur dioxide gas in the reaction are absorbed and the mother liquor subjected to pumping filtration is free of after treatment and is subjected to waste liquid delegation treatment so that environmental protection is promoted. |
