[0020] Example 1
[0021] A preparation method of diphenol propane diglycidyl ether, comprising the following steps:
[0022] The first step is to mix diphenol-based propane, diphenol-based propane by-products and epichlorohydrin, and add 50-70% benzyltriethylammonium chloride aqueous solution as a catalyst, and etherify at 75~125℃ The reaction time is 0.5-10 hours, the reaction temperature of the rice flower can be selected as 80, 90, and the reaction time can be selected as 1 hour, 3 hours, 6 hours, 8 hours, 9 hours,
[0023] Among them, the mass of diphenol-based propane by-product is 1 to 4 times the mass of diphenol-based propane, for example, it can be selected as 1.2, 1.4, 2.0, 2.4, 2.8, 3.5, 3.9 times, and the quality of epichlorohydrin is diphenol-based 4-40 times that of propane, for example, 6 times, 8 times, 15 times, 20 times, 28 times, 32 times, 35 times, 38 times, and the mass of benzyl triethyl ammonium chloride is diphenol propane 0.01 to 0.1 times of, for example...
