Description

Technical field:

[0001] The invention belongs to an ester amine quaternary ammonium salt and a synthesis method thereof, in particular to a synthesis of an ester amine quaternary ammonium salt compound using a quaternizing agent and a synthesis method thereof. Background technique:

[0002] At present, fabric softeners are mainly cationic surfactants. The first softener used commercially in 1950 was dihydrogenated tallow dimethyl amine chloride (DHTDMAC). While developing DHTDMAC, it was developed with fatty acids as raw materials. Products include diamidoethoxylated quaternary ammonium salts, ester quaternary ammonium salts, imidazoline quaternary ammonium salts and other products. However, these quaternary ammonium salt synthesis processes generally use methyl chloride, dimethyl sulfate, dipropyl sulfate or inorganic acids as quaternizing agents. There is no report for using dimethyl carbonate as the quaternizing agent to synthesize esteramine quaternary ammonium salts. ...
