Abstract
THE separation of vanillin and syringaldehyde produced by the oxidation of lignins with nitrobenzene in alkaline medium is of importance in lignin chemistry. Spruce lignin gives only vanillin1, whereas hardwood lignins give both aldehydes in relative quantities depending on the species2. Only limited success has attended efforts to separate them by chemical means2,3. Separation by vacuum sublimation2 employs 0·4 gm. of the mixed aldehydes and requires specialized equipment. The present communication shows that separation can be effected by paper partition chromatography using petroleum ether saturated with water as the mobile phase.
