Process for purifying crude dibenzylidene sorbitol |
| abstract |
Purified dibenzylidene sorbitol is prepared by mixing crude dibenzylidene sorbitol containing monobenzylidene sorbitol and tribenzylidene sorbitol as by-product impurities with a lower aliphatic alcohol to dissolve the impurities, and separating and recovering the undissolved dibenzylidene sorbitol. This process affords dibenzylidene sorbitol having a purity of at least 98% from crude dibenzylidene sorbitol with a purity of about 95%. |
