| titleOfInvention | A kind of cryogenic separation Styryl oxide and the device and method of hyacinthin |
| abstract | The invention provides the device and method of a kind of cryogenic separation Styryl oxide and hyacinthin, belong to field of fine chemical.Styryl oxide is important fine chemicals, is widely used in the organic synthesis such as medicine, spice as intermediate.With styrene for raw material production Styryl oxide, in product, Styryl oxide accounts for 94.1%, hyacinthin accounts for 5.9%.Owing to Styryl oxide and hyacinthin are isomers, dissolving each other completely and boiling point difference is little, boiling point is respectively 194 DEG C and 195 DEG C, uses atmospheric distillation means energy consumption too high, and separating effect is the best.For above-mentioned practical situation, the invention provides the device and method of a kind of cryogenic separation Styryl oxide and hyacinthin.According to the character that Styryl oxide is different from hyacinthin fusing point, design cryogenic crystallization and rectification under vacuum combined process. |
