Claims
- 1. A process which comprises (1) reacting one molar proportion of an amine oxide corresponding to the formula:
- RR'R"NO.multidot.xH.sub.2 O
- with y molar proportions of an aqueous hydrogen peroxide having a concentration of 50-80% by weight in an organic solvent to form a solution of perhydrate corresponding to the formula:
- RR'R"NO.multidot.xH.sub.2 O yH.sub.2 O.sub.2
- and (2) cooling the solution to crystallize the perhydrate; R in the above formulas being a primary alkyl group containing 8-24 carbons; R' being methyl, ethyl, or 2-hydroxyethyl; R" being independently selected from methyl, ethyl, 2-hydroxyethyl, and primary alkyl groups containing 8-24 carbons; x being 0 or 1; y being 1 or 2; and the sum of x and y being 2.
- 2. The process of claim 1 wherein both x and y are 1.
- 3. The process of claim 2 wherein R' is methyl.
- 4. The process of claim 3 wherein R is tetradecyl and R" is methyl.
- 5. The process of claim 3 wherein R and R" are tetradecyl.
- 6. The process of claim 1 wherein x is 0 and y is 2.
- 7. The process of claim 6 wherein R' is methyl.
- 8. The process of claim 7 wherein R is tetradecyl and R" is methyl.
- 9. The process of claim 7 wherein R and R" are tetradecyl.
