Paragraph 0045-0052, (2021/04/03)
The invention relates to a preparation method of trimethylolpropane diallyl ether. The preparation method comprises the following steps: controlling trimethylolpropane, alkali metal hydroxide and water to form a mixture in a reactor, dropwise adding part or all of the alkali metal hydroxide into the reactor in the form of an alkali metal hydroxide aqueous solution within a preset time to form a mixture, dropwise adding chloropropene into the reactor within the preset time, and controlling the molar ratio of water to trimethylolpropane to be 1-10, wherein the molar ratio of the trimethylolpropane to the alkali metal hydroxide to the water is 1: (a-1): (b-9), 0 a a reaction product to obtain the trimethylolpropane diallyl ether. By controlling the mixed introduction mode of alkali metal hydroxide and water and controlling the molar ratio of mixed reactants, adverse factors of water areovercome, the operation is simplified, the cost is reduced, and products are easy to separate.
