ABSTRACT:
A process for preparing 3-methyltetrahydrofuran is herein disclosed which comprises reacting a methacrylic acid ester with carbon monoxide and a lower aliphatic alcohol to obtain a methylsuccinic acid diester, and hydrogenating and dehydrating/cyclizing this methylsuccinic acid diester. According to this process, 3-methyltetrahydrofuran can efficiently be obtained from inexpensive starting materials.
