Participants

Reaction Steps

An amount of 25 g of ground Siam benzoin resin was dispersed in 500 ml of a solution (pH of 3) prepared by adding hydrochloric acid to water and was extracted five times by using 20 v/v% of diethylether in a separatory funnel. The combined ether layer was evaporated to remove solvents until the volume thereof reached 5 ml. Benzoic acid with a concentration of 5 g/l was detected by HPLC analysis.
