CAU-1-N3 organic-inorganic hybrid solid, equipped with an azide group, and process for its preparation

The invention relates to a process for transformation of lignocellulosic biomass or cellulose using stable non-zeolitic heterogeneous catalysts that are based on tin and/or antimony, preferably dispersed on a substrate. The use of these catalysts makes it possible to obtain directly lactic acid with high selectivity while limiting the production of oligosaccharides and soluble polymers.
