  • Process for production of lactic acid and equipment for the production
    Patent number: 7829740
    Abstract: A process for producing lactic acid according to the invention is characterized in that glycerin is subjected to a hydrothermal reaction under an alkaline condition at a temperature in the range of 150 to 400° C. and under pressure equal to or more than the saturated vapor pressure at the temperature. The glycerin produced from plant fats, animal fats or the like or pure product synthesized chemically or a discharge containing glycerin generated at the production of diesel fuel oil from fats, in which the fats are subjected to a transesterification with alcohol in the presence of an alkali catalyst in order to obtain fatty acid ester is preferably used as a starting material.
    Type: Grant
    Filed: June 29, 2006
    Date of Patent: November 9, 2010
    Assignees: Hitachi Zosen Corporation, Tohoku Electric Power Co., Inc.
    Inventors: Heiji Enomoto, Fangming Jin, Takehiko Moriya, Kenji Kakeda, Yoshitoshi Sekiguchi, Hisanori Kishida
  • APPARATUS FOR PRODUCING LACTIC ACID
    Publication number: 20100047140
    Abstract: An apparatus for producing lactic acid according to the invention comprises a reactor carrying out: subjecting glycerin to a hydrothermal reaction under an alkaline condition, supplying an alkaline solution comprising glycerin; and continuously producing lactic acid, wherein glycerin is subjected to a hydrothermal reaction under an alkaline condition at a temperature in the range of 150 to 400° C. and under pressure equal to or more than the saturated vapor pressure at the temperature. The glycerin produced from plant fats, animal fats or the like or pure product synthesized chemically or a discharge containing glycerin generated at the production of diesel fuel oil from fats, in which the fats are subjected to a transesterification with alcohol in the presence of an alkali catalyst in order to obtain fatty acid ester is preferably used as a starting material.
