Title:
PRODUCTION OF 3-METHYL-2-BUTENOL
Document Type and Number:
Japanese Patent JP3506531
Kind Code:
B2
Abstract:
PURPOSE: To obtain 3-methyl-2-butenol useful as a raw material for perfumes, agrochemicals, etc., on an industrial scale at a low cost in high efficiency without causing the problems of danger in the reaction, environmental pollution, etc., by carrying out isomerization reaction of 3-methyl-3-butenol in vapor phase in the presence of a specific catalyst.
CONSTITUTION: The objective compound is produced by isomerizing (A) 3- methyl-3-butenol in vapor phase in the presence of (B) magnesium oxide as a catalyst. The reaction is carried out e.g. at 100-500°C (especially 150-300°C) under atmospheric pressure by supplying 0.01-100 pts.wt. (especially 0.1-20 pts.wt.) of the component A based on 1 pt.wt. of the component B per unit time to a vapor-phase reactor containing the component B.
