One-pot two-step process directly converting biomass-derived carbohydrate to lactide

Chem Commun (Camb). 2022 Apr 7;58(29):4627-4630. doi: 10.1039/d2cc00093h.

Abstract

This study proposed a strategy for the production of lactide from biomass-derived carbohydrate with excellent yield, involving sugar to racemic lactic acid conversion over Sn-containing Beta zeolite and racemic lactic acid to lactide conversion over H-Beta zeolite. Structural characteristics of the resulting lactide and extensive applicability for various substrates are also presented.
