Abstract:
A method for preparation of a quaternary ammonium hydroxide, comprising reacting in the presence of watera tertiary amine of the formula R.sup.1 R.sup.2 R.sup.3 N, wherein R.sup.1 and R.sup.2 are independently selected from the group consisting of alkyl groups of from one to about eighteen carbon atoms, aryl groups of from six to about eighteen carbon atoms and alkylaryl groups of from seven to about eighteen carbon atoms, and R.sup.3 is selected from the group consisting of alkyl groups of from two to about eighteen carbon atoms, aryl groups of from six to about eighteen carbon atoms and alkylaryl groups of from seven to about eighteen carbon atoms, provided, however, that R.sup.2 and R.sup.3 may be joined to form a heterocyclic ring including the N and optionally an oxygen atom, withat least one alkylene oxide of from two to three carbon atoms, to produce a quaternary ammonium hydroxide of the formula R.sup.1 R.sup.2 R.sup.3 R.sup.4 NOH, wherein R.sup.1, R.sup.2 and R.sup.3 are as defined above and R.sup.4 is selected from the group consisting of ##STR6## wherein m and p are independently selected from integers from zero to about eighteen, provided that the sum m+p is from one to about eighteen, and --CHR.sup.5 CHR.sup.6 OH, wherein R.sup.5 and R.sup.6 are independently selected from the group consisting of hydrogen, alkyl groups of from one to about eighteen carbon atoms, aryl groups of from six to about eighteen carbon atoms, and alkylaryl groups of from seven to about eighteen carbon atoms.
