Abstract

PURPOSE: To obtain the titled compound advantageously suitable as an intermediate for an polyol useful as an antifreezing cooling agent, by dehydrohalogenating a vicinalhalo alcohol in the presence of a hydrohalide of an imidazole compound.
CONSTITUTION: A compound shown by the formulaI(R1WR4 are H, ≤16C alyl, alkenyl, aryl, which may have an electron attractive group such as halogen, CN, etc., aryl may have 1W4C alkyl, R1 and R4 may be linked to form cycloalyl ring; X is halogen, especially Cl or Br) is dehydrohalogenated in the presence of hydrochloride or hydrobrimide of a compound shown by the formula II or III (R5WR9 are H, CH3, C2H5, phenyl) compound shown by the formula II or III (R5WR9 are h, CH3, C2H5, phenyl) preferably in a gaseous phase at 150W 400°C, a halogen is recovered as a hydrogen halide having a wide range of use and high value of utilization, to give a compound shown by the formula IV advantageously.
