Title:
METHOD OF MANUFACTURING LACTIC ACID
Document Type and Number:
WIPO Patent Application WO/2014/157315
Kind Code:
A1
Abstract:
Provided is a method capable of obtaining, from glycerin, desired lactic acid having a high yield of 30% or greater, which is similar to conventional methods, under reaction conditions at lower temperature and lower pressure than conventional methods, the method reducing the amount of impurities included (preferably the impurity selectivity is 40% or less), and therefore not requiring a complicated purifying process. The lactic acid manufacturing method is characterized in using glycerin as a raw material, and inducing a hydrothermal reaction of the glycerin under alkaline conditions and in the presence of a catalyst containing at least one type of active element belonging to iron family elements, noble metal family elements, platinum family elements, and base metal elements.
