The process of transformation of glycerol alkaline solution into sodium lactate on Cu-containing oxides in a flow reactor at 200 - 240°C has been studied. It was shown that this process proceeds the most efficiently on Cu/MgO-ZrO2 catalyst with copper supported by strong basic oxide (Н + 27). A method for producing of lactic acid from 10% glycerol alkaline solution on Cu/MgO-ZrO2 catalyst was proposed, which provides 97% conversion of glycerol and 95% by lactic acid selectivity at 240° C and 2.4 MPa. The process of dehydration of ethyl lactate on NaY, NaX, NaA and L zeolites to obtain important monomer - ethyl acrylate in a flow reactor at atmospheric pressure has been studied. It was found that the most stable catalyst is NaY- faujasite, which provides 100% conversion of ethyl lactate with 80-90% by ethyl acrylate selectivity at 350°C.
