Claims4
A method for the production of O-substituted hydroxylamine compounds comprising:
- obtaining O-substituted hydroxylamine disulfonic acid alkali metal salts by reacting a hydroxylamine disulfonic acid alkali metal salt with a halide according to the following formula (1):
- (MSO3)2NOH+RX→(MSO3)2NOR+HX (1)
- wherein M is an alkali metal atom;
- R is an alkyl group, alkenyl group, alkynyl group, aryl group, aralkyl group, carboxyl group, ester group, or ether group, where each group may have a substituent;
- and X is a halogen atom;
- and
- hydrolyzing the obtained O-substituted hydroxylamine disulfonic acid alkyl metal salt.
