  • Process for producing acrylic acid
    Patent number: 8076509
    Abstract: The present invention provides a process for producing acrylic acid from glycerin with a catalyst having a prolonged life. In the process for producing acrylic acid from glycerin, a molar ratio of oxygen to glycerin in a raw material gas is set to be not lower than 0.8 and not higher than 20.
    Type: Grant
    Filed: November 28, 2007
    Date of Patent: December 13, 2011
