  • Process for preparing long chain N,N-dialkylhydroxylamines by direct oxidation
    Patent number: 5013510
    Abstract: N,N-Dialkylhydroxylamines where the alkyl groups are of 10 to 30 carbon atoms are prepared by an improved process involving the direct oxidation of the corresponding N,N-dialkylamines with aqueous hydrogen peroxide in a lower alkanol solvent in the absence of a catalyst or a sequestering agent.The improved process prevents the problem of over-oxidation and gives the desired N,N-dialkylhydroxylamine in high yield and purity. The N,N-dialkylhydroxylamines are effective stabilizers for polymer compositions particularly as process stabilizers for polyolefins.
