CATALYST FOR MANUFACTURING amp;alpha;, amp;beta;-UNSATURATED ETHER AND METHOD OF MANUFACTURING amp;alpha;, amp;beta;-UNSATURATED ETHER

摘要

PROBLEM TO BE SOLVED: To provide a catalyst suitable for efficient and long stable manufacturing α, β-unsaturated ethers and a method of manufacturing α, β-unsaturated ethers using the catalyst.;SOLUTION: The catalyst for manufacturing α, β-unsaturated ethers comprises (A) 50-99.999 mass% of a sulfate and (B) 0.001-50 mass% of a binder having a maximum acid strength, H₀, larger than +3.3, where H₀ is the Hammett acid strength. A method of manufacturing an α, β-unsaturated ether which pyrolyzes an acetal in the presence of the catalyst is also provided.;COPYRIGHT: (C)2008,JPO&INPIT
