Method of synthesizing alkyl gallates |
| abstract |
A method for synthesizing alkyl gallates. Gallic acid and an alkyl alcohol of the order of the desired gallate are heated in a reaction vessel in the presence of a catalyst such as sulfuric acid or para-toluene sulfonic acid. Water is generated, forming an azeotrope with the alkyl alcohol. Distillation or Soxhlet extraction using a drying agent removes the formed water. Upon completion of the reaction, the reaction mixture is added while stirring to an alkane solvent and cooled to produce crystals of the desired alkyl gallate. The crystals may be further recrystallized and washed to improve their purity. |
