text: By one method, the crude vanillin (herein, the crude concentrates obtained in the manufacture of synthetic vanillin from various source materials are also referred to as crude vanillin) along with impurities is first dissolved in a waterimmiscible organic solvent and then extracted with sodium bisulflte solution which selectively converts the vanillin (an aldehyde) to a sodium bisulfite-aldehyde addition compound which is soluble in water and insoluble in the organic medium.
