Solvent dosage is 10mL/ gram epichlorohydrin. The yield of 5-chloromethyl-2-oxazolidinone was more than 65.2%. 5-Chloromethyl-2-oxazolidinone and sodium phenolate were condensated to give 5-phenoxymethyl-2-oxazolidinone after taking off the sodium chloride in yield of 63.0%~78.0%. Dimethylsulfoxide was used as the solvent, and orthogonal experiment to the reaction condition had been carried out.
