<P>PROBLEM TO BE SOLVED: To raise a production rate per unit volume of a catalyst, and to provide an efficient production method which miniaturizes reaction equipment and a simple production method with an easy industrial operation in the production of DHP (3,4-dihydro-2H-pyran) from THFA (tetrahydrofurfuryl alcohol) by the gas phase method using a solid catalyst. <P>SOLUTION: THFA and a hydrogen gas are supplied by a gas phase in a process which produces 3,4-dihydro-2H-pyran from THFA under the presence of a catalyst which supports copper oxide (II) or rhodium to a solid oxide catalyst. <P>COPYRIGHT: (C)2012,JPO&INPIT |
