Latest Patents

Pellegrin's latest patents include a continuous hydrolysis process for preparing 2-hydroxy-4-methylthiobutanoic acid or its salts. This innovative process involves introducing an aqueous mineral acid into a nitrile hydrolysis reactor, which includes a continuous stirred tank reactor. The process allows for the continual hydrolysis of 2-hydroxy-4-methylthiobutanenitrile, resulting in the production of 2-hydroxy-4-methylthiobutanamide. This product is then further hydrolyzed in an amide hydrolysis flow reactor to yield an aqueous hydrolyzate containing 2-hydroxy-4-methylthiobutanoic acid, which is subsequently recovered.

Another patent focuses on a similar continuous hydrolysis process for the preparation of 2-hydroxy-4-methylthiobutanoic acid. In this method, sulfuric acid is introduced into a first reactor, where 2-hydroxy-4-methylthiobutanenitrile is continually hydrolyzed to produce an intermediate aqueous hydrolysis solution. This solution is then processed in a plug flow reactor to yield the desired aqueous hydrolyzate product solution containing 2-hydroxy-4-methylthiobutanoic acid.
