PRODUCTION OF UNSATURATED ETHER AND CATALYST FOR PRODUCING UNSATURATED ETHER

Japanese Patent JP2740479

B2

PURPOSE: To simply and safely produce an unsaturated ether compound by a direct one step reaction from an inexpensive and easily available glycol ether compound in the presence of a specific catalyst without using an auxiliary raw material and a solvent.
CONSTITUTION: (B) A glycol ether compound is subjected to an intramolecular dehydration reaction in a gaseous phase in the presence of a catalyst especially preferably comprising an oxide of formula: MaSibXcOd (M is alkali metal element; X is at least one of Ti, Zr, V, Nb, Ta, Cr, Mo, W, B, Al, Ga, In, Tl, Ge, Sn, Pb, P and Sb; when a is 1, b is 1-500, c is 0-1, d is a number determining by the values of a-c and by the binding states of various constituting elements) to obtain (C) the converted unsaturated ether compound. For example, a vinylic ether compound of formula II is obtained from a glycol ether compound of formula I (R is 1-7C hydrocarbon, etc.; R' is independently H, methyl, etc.; n is 1, 2).
