Abstract
Abstract Quaternary ammonium salts are produced in substantial yields within a reasonable time by reacting, in the presence of water, a tertiary amine and 1-halo, 2-hydroxy, 3-alkoxy propane or by reacting the corresponding tertiary amine hydrohalide and glycidyl ether. The compositions possess surfactant properties and can be used as emulsifying agents, germicides, etc.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
21 words
The method of claim 1 wherein the reaction takes place at temperatures of from about 75* C. to about 100* C.
Claim 2
Dependent Claim
15 words
The method of claim 1 wherein the 1-halo, 2-hydroxy, 3-alkoxy propane is a 1-chloro propane.
Claim 3
Dependent Claim
14 words

Claim 4
Dependent Claim
48 words
The method of claim 1 wherein the tertiary amine is selected from the group consisting of trialkyl amines having one to four carbon atoms in the alkyl chains, trialkyl amines wherein at least one alkyl group has five to 22 carbon atoms, ditertiary amines and cyclic tertiary amines.
Claim 5
Independent Claim
91 words
A method for the quaternization of tertiary amines with a 1-halo, 2-hydroxy, 3-alkoxy propane comprising: reacting in the liquid phase under reflux conditions, substantially stoichiometric amounts of a tertiary amine and a 1-halo, 2-hydroxy, 3-alkoxy propane wherein the alkyl of the alkoxy group is a carbon chain of from about eight to about 18 carbon atoms, in the presence of a solvent comprising 15-100 percent water and 0-85 percent isopropyl alcohol, said solvent being present in an amount of greater than about 15 percent based upon the weight of the reactants.
Claim 6
Dependent Claim

Claim 7
Dependent Claim
34 words
The method of claim 6 wherein the halogen substituent of the 1-halo, 2-hydroxy, 3-alkoxy propane is chlorine, and wherein said alkoxy propane is the reaction product of a 10-14 carbon fatty alcohol and epichlorohydrin.
