White crystalline powder | [Preparation]
Mandelic acid can be prepared by the hydrolysis of amygdalin with sulfuric acid or of mandelonitrile with hydrochloric acid. The mandelonitrile can be prepared by the action of hydrocyanic acid on benzaldehyde, and by the action of sodium or potassium cyanide on the sodium bisulfite addition product of benzaldehyde. The procedure described differs from earlier methods in that the sodium bisulfite addition compound of benzaldehyde is prepared in the presence of sodium cyanide and the nitrile is formed immediately.
