| titleOfInvention | A kind of ultrasonic wave promotes the method for producing β-vitamin k4 |
| abstract | The invention discloses a kind of ultrasonic wave and promote the method that β-vitamin k4 is produced.Oxidation solution is mixed with sodium dichromate and sulfuric acid, oxidation solution is slowly joined in the medium including the mixing of beta-methylnaphthalene, phase-transfer catalyst and water and react, in reaction process by ul-trasonic irradiation in reaction system, because ultrasonic wave is to the promoter action of reaction, greatly can reduce the temperature of reaction system, reduce the generation of side reaction, improve product yield, greatly can reduce the consumption of oxidation solution. |
