According to the present invention a process is provided for producing glycolide which comprises contacting glycolaldehyde dimer with an oxidizing agent to produce a glycolide product. Preferably, the process is carried out in an aprotic environment, such as in a reaction mixture comprising the glycolaldehyde dimer, the oxidizing agent, the glycolide product and an aprotic solvent.

Process for preparing glycolide

The following invention regards a process of demethylating a methyl ester of methionine or its hydroxy analog and producing methane thiol as a side-product. The methionine and its hydroxy analog are suitable as an animal feed additive and as a food additive. The methane thiol may be consumed in a hydrothiolation step such as in a step of preparing the methyl ester of methionine or its hydroxy analog from methyl vinyl glycolate.

Demethylation of methyl ester of methionine and its hydroxy analog

A process for the preparation of ethylene glycol and other C-Chydroxy compounds comprising the steps of hydrogenating a composition comprising C-Coxygenate compounds. In particular the process is suitable for hydrogenating a composition comprising different C-Coxygenate compounds, such as the product from a thermolytic fragmentation of a sugar composition.

Process for the preparation of ethylene glycol from sugars

New adipate-type compounds suitable as an intermediate in organic chemistry, a platform chemical for the production of other chemicals, and as a monomer and a co-monomer useful for the preparation of polymers and co-polymers. Also, a process of preparing the new adipate-type compounds from bio-based raw materials such as sugars.
