Abstract
Official abstract text for this publication.
The present invention provides a production method for indene, comprising a dehydrogenation step of obtaining a reaction product containing indene by contacting a raw material gas containing indane and molecular hydrogen with a dehydrogenation catalyst, wherein the dehydrogenation catalyst comprises a support containing aluminum, and a supported metal supported on the support, the supported metal contains a group 14 metal element and platinum, and an atomic ratio of the group 14 metal element to the platinum in the dehydrogenation catalyst is 8.0 or less.
First claim
Opening claim text (preview).
The invention claimed is: 1. A production method for indene, comprising obtaining a reaction product containing indene by contacting a raw material gas containing indane and molecular hydrogen with a dehydrogenation catalyst, wherein the dehydrogenation catalyst comprises a support containing aluminum, and a metal supported on the support, the metal contains a group 14 metal element and platinum, and an atomic ratio of the group 14 metal element to the platinum in the dehydrogenation catalyst is 8.0 or less. 2. The production method according to claim 1 , wherein the atomic ratio of the group 14 metal element to the platinum in the dehydrogenation catalyst is 3.5 or more and 7.0 or less. 3. The production method according to claim 1 , wherein the group 14 metal element is tin. 4. The production method according to claim 1 , wherein the group 14 metal element and the platinum are supported on the support by using a metal source not containing a chlorine atom. 5. The production method according to claim 1 , wherein a molar ratio of the molecular hydrogen to the indane in the raw material gas is 3.5 or less. 6. The production method according to claim 1 , further comprising obtaining the indane by dehydrogenation reaction of tetrahydroindene.
