Abstract
Official abstract text for this publication.
The present invention relates to a heterogeneous catalyst for preparing acrylic acid from allyl alcohol, and a method of preparing acrylic acid from allyl alcohol using the same. More particularly, the present invention relates to a method of preparing acrylic acid from allyl alcohol at a high yield by performing a liquid phase reaction in the presence of a heterogeneous catalyst including gold supported on a carrier.
First claim
Opening claim text (preview).
What is claimed is: 1. A heterogeneous catalyst for preparing acrylic acid from allyl alcohol, wherein the catalyst includes gold having a particle size of 5 nm or less supported on a carrier, wherein the carrier is cerium oxide (CeO 2 ) or a composite oxide containing cerium oxide (CeO 2 ). 2. The heterogeneous catalyst of claim 1 , wherein the gold has a particle size of 1 nm or less. 3. The heterogeneous catalyst of claim 1 , wherein the gold is included in an amount of 5 wt % or less based on a total dry weight of the carrier.
