PROBLEM TO BE SOLVED: To provide a method for simply producing an alkoxyalkyl group-containing quaternary ammonium salt in a high yield by using a readily available raw material. SOLUTION: The method for producing the alkoxyalkyl group-containing the quaternary ammonium salt comprises reacting a hydroxyalkyl group-containing tertiary amine represented by general formula (1) (wherein R1 and R2 are each independently a 1-4C alkyl group or A-OH and R1 and R2 together may form a ring structure; A is an alkylene chain or an oxyalkylene chain) with an alkyl halide ≥2 equivalent to the hydroxyalkyl group-containing tertiary amine and an alkali metal hydride at least equivalent to the hydroxyalkyl group-containing tertiary amine in an aprotic solvent.

By analysis of fully coupled 13C NMR spectra and of 1H NMR spectra of dimethylaminoethanol, its methyl ether, and of the corresponding trimethylammonium iodides, populations of isomers generated by rotation about the bonds N-CH2, CH2-CH2, and CH2-O in these compounds in solution were determined.By analysis of Raman and infrared spectra of these compounds in the solid and liquid states it was found that in the crystalline state these compounds form structures with parallel N-CH3 and O-CH2 bonds, which are also preffered in the liquid state.
