METHOD OF N,N-DIMETHYLDODECYLAMINE OXIDE AQUEOUS SOLUTION PREPARING Russian patent published in 1996 - IPC

Abstract SU 1839434 A1

FIELD: chemical technology. SUBSTANCE: product: N,N-dimethyldodecylamine oxide, empirical formula is C14H31NO d204

=0,966, n20D
=1,380. Reagent 1: N,N-dimethyldodecylamine. Reagent 2: 7.1-9.1% solution of H2O2. Reaction conditions: molar ratio of N,N-dimethyldodecylamine : H2O2 = 1:(1.1-1.5). Firstly, at 20 C, then at 35-55 C followed by self-heating use to 70-90 C for 20-60 min, cooling to 30-60 C for 1-2 hr. Excess of H2O2 is destroyed with catalase. EFFECT: improved method of preparing.
