Abstract

PURPOSE: To produce the titled compounds at the same time, by using inexpensive isoprene, CO and an alcohol as raw materials, reacting the raw materials with each other in the presence of Pd, etc., pyridine, etc., or HCl, etc., and reacting the resultant ester having a specific boiling point range with water and/or a carboxylic acid in the presence of an acid catalyst.
CONSTITUTION: Isoprene is made to react with carbon monoxide and a 1W4C alcohol (e.g. methanol) in the presence of a group VIII metal compound (e.g. Pd compound, Co compound, etc.) and an aromatic tert-amine (e.g. 2-picoline) in the presence of hydrogen halide, and an ester having a boiling point of 130W220°C (in terms of the boiling point under normal pressure) is separated from the reaction liquid. The ester is made to react with water and/or a 1W4C carboxylic acid (e.g. formic acid, acetic acid, etc.) in the presence of an acid catalyst (e.g. phosphoric acid, BF3, etc.), and γ-methyl-γ-valerolactone is separated from 3-methylpentenoic acid.
USE: Raw material for solvent, perfume, etc.
