Abstract
Novel perhydrates having utility as surfactants and bleaching agents are obtained by reacting an anhydrous amine oxide or an amine oxide monohydrate with hydrogen peroxide in such proportions as to provide a compound corresponding to the formula RR'R"NO.multidot.xH.sub.2 O.multidot.yH.sub.2 O.sub.2 in which R is a primary alkyl group containing 8-24 carbons; R' is methyl, ethyl, or 2-hydroxyethyl; R" is independently selected from methyl, ethyl, 2-hydroxyethyl, and primary alkyl groups containing 8-24 carbons; x is 0 or 1; y is 1 or 2; and x+y is .ltoreq.2.
Claims9
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.
