Latest Patents
Larkin holds a patent for the "Preparation of esters of carboxylic acids." This patent discloses a process wherein a solution of a carboxylic acid in a first solvent and an alcohol are fed to a simulated moving bed reactor (SMBR) containing a solid to produce a first stream comprising a solution of an ester of the carboxylic acid and the alcohol. The second stream comprises the first solvent. The solid present in the SMBR facilitates the esterification reaction and the separation of the first solvent from the carboxylic acid. This process is particularly valuable for preparing an alkanol solution of an alkyl 2-keto-L-gulonate ester (AKLG) from an aqueous fermentation broth containing dissolved 2-keto-L-gulonic acid (KLG). By feeding the fermentation broth and an alkanol to the SMBR, which contains a solid acidic esterification catalyst, a stream comprising an alkanol solution of an ALKG is produced. This alkanol solution of an ALKG may be used directly to convert the ALKG to ascorbic acid (Vitamin C). Larkin's patent portfolio includes 1 patent.
