| titleOfInvention | Method of separating vanillin from lignin oxidation products |
| abstract | FIELD: chemistry. n SUBSTANCE: present invention relates to a method of separating vanillin, which is widely used in food, perfume-cosmetic and pharmaceutical industries, from lignin oxidation products by reacting vanillin-containing extracts with aqueous sodium hydrosulphite NaHSO 3 solutions. The solutions used have sodium hydrosulphite concentration of 320-400 g/l and the vanillin-hydrosulphite derivative formed is separated from excess sodium hydrosulphite solution in form of a precipitate by filtration, centrifuging or decantation. n EFFECT: method enables to cut consumption of sodium hydrosulphite and increases the distribution ratio of vanillin into the precipitate and aqueous phase from the organic phase, which reduces the volume of extracts and re-extracts when separating vanillin. n 3 ex |
