摘要：
A process for producing 2-hydroxy-4-methyltetrahydrofurane, which comprises making 2-methyl-2-propen-1-ol react with hydrogen and carbon monoxide in the presence of:
(a) rhodium compound, and
(b) tris(substituted aryl) phosphite having an electronic parameter ( ν -value) of 2080 to 2090 cm -1 and a steric parameter (θ-value) of 135 to 190°C and being represented by the following general formula (1):
(wherein R 1 , R 2 and R 3 independently represent a substituted aryl group with 7 or more carbon atoms) at a ratio of 110 to 1000 moles per 1 gram atom of rhodium.
