Abstract
The invention relates to a preparation method of a novel compound namely an epichlorohydrin tetramer and a reaction between the epichlorohydrin tetramer and formaldehyde derivatives. Epichlorohydrin is an industrial raw material which is cheap and easily available; by taking water and an organic solvent as a solvent, epichlorohydrin can generate self-condensation at room temperature in the presence of a strong base and a phase transfer catalyst to obtain a novel epichlorohydrin tetramer. The tetramer can react with the formaldehyde derivatives after reacting with the strong base, so that a series of propargyl glycidyl ether derivatives can be obtained. The first-step reaction is mild in condition and simple in operation, and provides new clues for new uses in exploring epichlorohydrin in the future. The second-step reaction is a preliminary attempt of the application of the novel tetramer, and provides a new method for preparing the propargyl glycidyl ether derivatives at the same time.
