Process for the preparation of lactic acid from glycerol

摘要

The invention relates to chemical technology, particularly to methods for production of lactic acid from glycerol. The proposed method contains following steps: i) obtaining of mono-metallic supported platinum containing catalyst by following consecutive steps: a) obtaining of platinum-containing precursors by extraction of platinum compound from hydrochloric acid solution with trioctylamine ((C₈H₁₇)₃N) solution in toluene, b) carrier impregnation with the platinum containing organic precursor solution, obtained in the previous step, c) drying of the impregnated carrier, d) platinum pyrolytic reduction; ii) glycerol oxidation by molecular oxygen in the presence of supported platinum-containing catalysts in alkaline aqueous solutions.
