Embodiment 1
[0345] Using a 1.5-liter jacketed reactor equipped with a nozzle for introducing oxygen-containing gas, agitating turbine blades and baffles at the bottom of the reactor, and a reflux cooler in the exhaust line at the upper part of the reactor, into the reactor Add the previously prepared mixture of 0.1026g of cuprous oxide and 0.7712g of 47% hydrogen bromide and 0.2471g of N,N'-di-tert-butylethylenediamine, 3.6407g of dimethyl n-butylamine, 1.1962g Di-n-butylamine, 894.04g of toluene, 73.72g of 2,6-dimethylphenol, 26.28g of 1,1,3-tris(2-methyl-4-hydroxy-5-tert-butylphenyl ) butane (manufactured by ADEKA: AO-30). Then, while vigorously stirring, the nozzle was used to introduce air into the reactor at a rate of 1.05 L / min, and at the same time, heat medium was passed into the jacket to adjust the polymerization temperature to keep it at 40°C. After 160 minutes after starting to introduce air, the ventilating of air was stopped, and 1.1021 g of ethylenediaminetetraacetic acid ...

[0347] Using a 1.5-liter jacketed reactor equipped with a nozzle for introducing oxygen-containing gas, agitating turbine blades and baffles at the bottom of the reactor, and a reflux cooler in the exhaust line at the upper part of the reactor, into the reactor Add the previously prepared mixture of 0.1081g of cuprous oxide and 0.8126g of 47% hydrogen bromide and 0.2603g of N,N'-di-tert-butylethylenediamine, 3.8360g of dimethyl n-butylamine, 1.2604g Di-n-butylamine, 893.72g of toluene, 76.33g of 2,6-dimethylphenol, 23.67g of 1,1-bis(2-methyl-4-hydroxy-5-tert-butylphenyl)butyl Alkane (manufactured by ADEKA: AO-40). Then, while vigorously stirring, the nozzle was used to introduce air into the reactor at a rate of 1.05 L / min, and at the same time, heat medium was passed into the jacket to adjust the polymerization temperature to keep it at 40°C. After 160 minutes after starting to introduce air, the venting of air was stopped, and 1.1612 g of ethylenediaminetetraacetic acid tet...
