Title:
第三アミンオキシドの合成
Document Type and Number:
Japanese Patent JP4272722
Kind Code:
B2
Abstract:
A process is provided for the manufacture of free-flowing solid tertiary amine oxides having N-nitrosodimethylamine levels of less than about 250 ppb. The process comprises heating a mixture of a tertiary amine, a polar hydroxy alkyl solvent, an organic acid, and aqueous hydrogen peroxide, followed by removal of the solvent and water, preferably by azeotropic removal. The resultant tertiary amine oxides have good color without bleaching and are useful without further purification.
