[0020] Example 1
[0021] The production formula of epoxy polyether alcohol is as follows in parts by weight:
[0022] Catalyst: 2 parts of potassium hydroxide, 100 parts of a mixture of glycerol and polyglycerol, 1076: 0.1 part of antioxidant, 168: 0.15 part of antioxidant.
[0023] The production process of epoxy polyether alcohol is as follows:
[0024] Put 2 grams of potassium oxyoxide, 100 grams of glycerol and polyglycerol mixture, 0.1 grams of antioxidant 1076 and 0.15 grams of antioxidant 168 into the reactor, vacuum to -0.99MPa, and then fill the reactor with nitrogen to 0.2 Kgf / cm 2 , The temperature of the material slowly rises to 245±2℃, and the pressure of the reactor is controlled at 1.0Kgf / cm 2 React for 12 hours; use cooling water to lower the temperature to 205±5°C, vacuum for 2 hours at -0.99MPa, and then lower the temperature to 90°C to discharge the product to obtain the epoxy polyether alcohol product.
