发明名称 PROCESS FOR PRODUCING 3-METHYLTETRAHYDROFURAN, AND PROCESS FOR PRODUCING AN INTERMEDIATE THEREOF
摘要 The present invention provides: 1. a process for producing 3-methyltetrahydrofuran, comprising the steps of reacting 3-methyl-3-buten-1-ol with hydrogen peroxide in the presence of zeolite to obtain 3-hydroxy-3-methyltetrahydrofuran, and reacting the resultant 3-hydroxy-3-methyltetrahydrofuran with hydrogen in the presence of an acidic substance and a hydrogenation catalyst. 2. a process for producing 3-methyltetrahydrofuran, comprising reacting 3-hydroxy-3-methyltetrahydrofuran with hydrogen in the presence of an acidic substance and a hydrogenation catalyst. 3. a process for producing 3-hydroxy-3-methyltetrahydrofuran, comprising reacting 3-methyl-3-buten-1-ol with hydrogen peroxide in the presence of zeolite. 4. a process for producing 3-methyldihydrofuran, comprising dehydrating 3-hydroxy-3-methyltetrahydrofuran in the presence of an acidic substance. 5. a process for producing 3-methyltetrahydrofuran, comprising reacting 3-methyldihydrofuran with hydrogen in the presence of a hydrogenation catalyst, and 6. a process for producing 3-methyltetrahydrofuran, comprising cyclizing 3-methyl-3-buten-1-ol in the presence of iodine.
