Method for inhibiting the formation of Nitrosamines in a reaction mixture containing Hydrogen peroxide and a secondary or Tertiary Amine.

摘要

The reaction of imine matrix containing hydrogen peroxide may encounter some problems, especially in the case of metal transition. These problems include primary impurities, especially nitro minerals with obvious carcinogenicity, and the production of a damaged product. These problems can be overcome by the use of free radical scrubber mixed reactions, including in particular substituted phenols and polyhydroxy aromatic compounds. Scrubbers have advantages when used with condensed metal agents such as polycarbonates or organic monopolies.
