Abstract
PURPOSE: To carry out the purification and concentration of the titled compound, by adding an alkali or alkaline earth metal hydroxide (A) to a dilute aqueous solution of a quaternary ammonium compound (B), and separating the mixture into a layer composed of a concentrated aqueous solution of the compound (B) and a layer composed of an aqueous solution of the compound (A).
CONSTITUTION: An alkali or alkaline earth metal hydroxide (A) is added to a dilute aqueous solution of a quaternary ammonium compound (B)[e.g. the compound of formulaI(R1 and R2 are 1W24C alkyl, benzyl, etc.; R3 and R4 are 1W10C alkyl; X is anion residue) or formula II (R5 is 1W24C alkyl; R6 is H or CH3)]which may contain salts as impurities, and the mixture is stirred at -20W+30°C and separated into the layer of concentrated aqueous solution of the compound (B) and the layer of aqueous solution of the compound (A). The concentration of alkali in the system is preferably 10W20wt%.
USE: Disinfectant, emulsifier, rustproofing agent, reaction catalyst, solvent, etc.
