| titleOfInvention | A kind of Trimethyl glycine hydrochloride mother liquor treatment process |
| abstract | A kind of Trimethyl glycine hydrochloride mother liquor treatment process, step is as follows: Trimethyl glycine hydrochloride mother liquor is heated to 85 ~ 95 DEG C, filters remove portion color and solid impurity; Mother liquor concentrations is thick to becoming sticky, and be cooled to 40 DEG C ~ 50 DEG C under stirring, add liquid caustic soda adjust ph to 8 ~ 9, temperature control is no more than 80 DEG C, produces a large amount of Trimethylamine 99 and departs from system; PH regulator is complete, and heating steams portion of water; Be cooled to 55 ~ 65 DEG C and add salt acid for adjusting pH value to 3 ~ 4; Heating under reduced pressure concentrates, removing moisture, when system thickness, stops heating, adds the methyl alcohol of half solid substance weight 4 ~ 5 times in still, continues to stir 10min ~ 30min; Filtration from sodium chloride, and sodium-chlor is reclaimed; Concentrated methyl alcohol, obtains solid Trimethyl glycine hydrochloride.Trimethyl glycine hydrochloride mother liquor effectively can be recycled utilization by the present invention. |
