Abstract
A method for the synthesis of anhydrous quaternary ammonium hydroxides having the formula (NR1R2R3R4) OH, wherein R1, R2, R3 and R4 are the same as or different from one another and are each individually selected from H, C1-C10 alkyls including linear or cyclo alkyls, and C6-C12 aryls by reacting an alkylene oxide with a tertiary amine having the formula R1R2R3N wherein R1, R2, and R3 are the same or different and are each individually selected from C1-C10 alkyls including linear and cyclo alkyls, C1-C10 hydroxyalkyls, C6-C12 aryls, and formulations having anhydrous quaternary ammonium hydroxides.

A method for the synthesis of an anhydrous quaternary ammonium hydroxide comprising:
- reacting an alkylene oxide with a tertiary amine having the formula R1R2R3N wherein R1, R2, and R3 are the same or different and are each individually selected from C1-C10 alkyls, C1-C10 hydroxyalkyls and C6-C12 aryls, to produce an anhydrous quaternary ammonium hydroxide having the formula (NR1R2R3R4) OH, wherein R1, R2, R3, and R4 are the same as or different from one another and are each individually selected from H, C1-C10 alkyls, C1-C10 hydroxyalkyls and C6-C12 aryls.
An anhydrous quaternary ammonium hydroxide composition obtained by reacting an alkylene oxide with a tertiary amine having the formula R1R2R3N wherein R1, R2, and R3 are the same or different and are each individually selected from C1-C10 alkyls, C1-C10 hydroxyalkyls and C6-C12 aryls.
