  • Process for preparing glycolide
    Patent number: 11603362
    Abstract: 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.
    Type: Grant

  • Demethylation of methyl ester of methionine and its hydroxy analog
    Patent number: 11370750
    Abstract: 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.
