Recovery of calcium pantothenate |
| abstract |
Calcium pantothenate is recovered from methanol solution by azeotroping the methanol with a suitable solvent. A methanol solution of calcium pantothenate is added at a regulated rate to a solvent such as octane heated above the methanol boiling point and methanol is removed by distillation as a methanol-solvent azeotrope leaving the calcium pantothenate in the form of a slurry in the azeotroping solvent. The distillation is carried out continuously but the solids may be removed continuously or collected in the still as a batch for subsequent removal. |
