Phosphotungstic Acid Ionic Liquid Catalyst
Phosphotungstic acid ionic liquid catalyst is use phosphotungstic acid ionic liquid as catalyst, ionic liquid has low volatility and thermal stability, it is fine solvent and catalyst for green synthesis.
Phosphotungstic Acid Ionic Liquid Catalyst Application
1. Phosphotungstic acid ionic liquid catalyst can be used in oxidative desulfurization technology, mix it with 30% hydrogen peroxide and petroleum, mix and heat under 25~70℃ for 0.5~3.0 hours. After reaction, separate the upper oil which is the desulfurization product.
2. Replace maleimide in catalytic synthesis, has the advantages of easy to recycle and can be reused.
3. It is reported that silica supported phosphotungstic acid ionic liquid catalyst has been produced, it is stable under 250℃, catalyzed oleic acid in biodiesel esterification process has good catalytic activity, the oleic acid conversion rate can reach 48.49%, specific surface area, pore volume and activity lower with bond density increases.
