Agent.
But the color of dodecyldimethyl hydroxyethyl ammonium chloride at this stage crosses duplicate removal, preparation process is also more multiple
It is miscellaneous.
Summary of the invention
The purpose of the present invention is to provide the high dodecyl dimethyl ethoxy chlorinations of a kind of simple production process, quality
The production technology of ammonium.
To achieve the above object, the invention provides the following technical scheme: a kind of dodecyldimethyl hydroxyethyl ammonium chloride
Production technology complete the life of dodecyldimethyl hydroxyethyl ammonium chloride by the selection and quaternization step of raw material
It produces；Specific step is as follows:
(1) raw material select: selecting chlorethanol, Dodecyl Dimethyl Amine as raw material；
(2) quaternization: after being uniformly mixed by chlorethanol and Dodecyl Dimethyl Amine, be heated to reaction temperature
It is reacted, generates dodecyldimethyl hydroxyethyl ammonium chloride, that is, complete dodecyldimethyl hydroxyethyl ammonium chloride
Production.
Preferably, the reaction molar ratio of the chlorethanol in the step (2) and Dodecyl Dimethyl Amine is 1:1-
1.12。
Preferably, the reaction temperature in the step (2) is 60-80 DEG C, and the reaction time is 2-4 hours.
Compared with prior art, the beneficial effects of the present invention are: preparation process of the invention is simple, operating comfort is high,
Reaction raw material are easy to get, and reduce reaction temperature, keep reaction temperature energy consumption lower, process safety, green, reaction yield are up to
99%, product colour can achieve colourless, purity is high, while stable processing technique is reliable.
Detailed description of the invention
Fig. 1 is production technological process of the invention.
