摘要: A method for producing lactide from C 3 -polyols that provides in the first step of the technological process the catalytic conversion of alcohol mixtures of C 3 -polyols into methyl lactate on a solid catalyst in a flow-through reactor; and in the second step of the technological process - a reaction of methyl lactate transesterification into lactide by passing methyl lactate vapors over a heterogeneous oxide catalyst in the absence of a carrier gas and under reduced pressure. A solution of glycerin or propylene glycol in methanol is used as alcohol mixtures of C 3 -polyols. In the first step of the technological process, granulated oxides from the following list are used as the catalyst: CuO/Al 2 O 3 , CuO-Cr 2 O 3 /Al 2 O 3 , CuO-SnO 2 /Al 2 O 3 , CuO-ZnO/Al 2 O 3 , CuO-TiO 2 /Al 2 O 3 , CeO 2 /Al 2 O 3 , and in the second step, the catalytic condensation of methyl lactate vapors into lactide is carried out.
