Abstract
A method for producing an amine oxide by oxidation of a tertiary amine in a reactor under continuous introduction of tertiary amine in a reaction fluid and export of amine oxide, wherein a suitable surface-to-volume ratio and/or a suitable flow speed with corresponding surface/volume loads are selected in the continuous process. The reaction fluid is usually reacted in the reactor with a laminar flow.
Claims20
A method for producing an amine oxide, comprising:
- oxidation of a tertiary amine in a reactor with an elongate hollow body, under continuous introduction of tertiary amine in a reaction fluid and export of amine oxide, wherein
- i) a surface-to-volume ratio of 0.5 m2/m3 or more is provided in the hollow body, at least over a length of the hollow body in which the amine is oxidised to an extent of 50 mol %;
- ii) a specific surface load of 1 l/m2h to 40 l/m2h is provided in the hollow body;
- and/or
- iii) a specific volume load of 1,000 l/m3h to 30,000 l/m3h is provided in the hollow body;
- and
- wherein
- the reaction fluid is guided in the hollow body with a laminar flow.
