PROCEDURE FOR THE PREPARATION OF VANILLIN |
| abstract |
The invention relates to a method for the production of vanillin in the form of a very pure product by oxidizing lignin contained in the wood pulping liquor. According to the invention the separation and purification of vanillin from the reaction mixture is carried out by means of an extraction at a supercritical pressure and temperature. Carbon dioxide, for instance, can be used as a extraction gas. |
