Document Type and Number:
WIPO Patent Application WO/2011/002023
Kind Code:
A1
Abstract:
Disclosed is an industrially usable method for producing acrolein from glycerin, which is obtained as a by-product in the process of producing a biodiesel fuel from a waste vegetable/animal oil or fat using an alkali catalyst, through a treatment with the use of supercritical water. Specifically disclosed is a method for producing acrolein, characterized by comprising: a measurement step for measuring the concentration of hydrogen ion in glycerin obtained as a by-product; an acid-addition step for adding an acid, in such an amount as to acidify said glycerin that can be determined based on the measurement result, to said glycerin; and a supercritical water-treatment step for treating the glycerin, to which the acid has been added, with supercritical water to thereby produce acrolein from glycerin.
