摘要:The present invention provides a process for the catalytic synthesis of lactide, comprising: mixing a lactic acid oligomer with a composite catalyst; and synthesizing lactide under a heating condition, and collecting the product using a vacuum distillation mode. The used composite catalyst is composed of a zinc or tin compound and an alkali metal compound. Compared with the prior art, the advantages of the present invention are that: the used composite catalyst features a high production rate with a small use amount, a low reaction temperature (150-220°C), and a short reaction time (2-5 h), has a single pass yield that may reach 95% or more, reduces energy consumption compared with the prior art, and facilitates industrial implementations.

摘要:A multidentate phosphite ligand is used in the catalytic synthesis of adiponitrile. The ligand is represented by the following general formula (I). The method of catalytic synthesis of adiponitrile comprises primary hydrocyanation, isomerization, and secondary hydrocyanation reactions, wherein the catalyst adopted each comprises a phosphite ligand-nickel complex composed of a nickel precursor and a multidentate phosphite ligand. The ligand molecule has a higher electron cloud density, and the phosphorus content capable of participating in coordination in the ligand molecule per unit mass is higher, so that the catalytic activity of the catalyst is improved, and the amount of the catalyst is reduced.
