Title:
PRODUCTION METHOD OF AMINE OXIDE
Document Type and Number:
Japanese Patent JP2003096048
Kind Code:
A
Abstract:

To provide a production method that can obtain a high-quality amine oxide which contains less residual unreacted aliphatic tertiary amine and hydrogen peroxide, hardly contains trace metals and is very stable in color, odor and so on during its storage.

This is a method for producing an amine oxide by reacting an aliphatic tertiary amine represented by formula (I) with hydrogen oxide. In this case, characteristically, a chelating agent is added after the aliphatic tertiary amine is reacted with hydrogen oxide. In formula (I), R1 is an 8-36C hydrocarbon group, R2 and R3 are each a 1-4C alkyl or hydroxyalkyl group, AO is a 2-4C oxyalkylene group and n, an average mole number, satisfies the equation 0≤n≤11.
