    摘要: After pyrolysis of N-.alpha.-methoxyethyl-O-methylurethane, it is possible to obtain very pure O-methyl-N-vinylurethane by cooling the pyrolysate and separating off the crystalline product. After separating off the O-methyl-N-vinylurethane, it is possible to react the mother liquor with methanol in the presence of bases and then to pass the reaction product to another pyrolysis.
