| titleOfInvention | A kind of method photocatalytically carrying out ethoxylation generation polyethers |
| abstract | The present invention relates to photocatalytically carry out the method that ethoxylation generates polyethers, alkenyl alcohol compound is added in reaction vessel, is subsequently adding nano-TiO 2 Photocatalyst and reducing agent, through N 2 It is passed through oxirane or expoxy propane after displacement, makes material be fully contacted with outer circulation mode by stirring and mix homogeneously, keep the pressure of reaction system at 2 ~ 3kg/cm 2 ï¼›Introduce light source to be irradiated to reaction system, be warming up to 70 ~ 80 DEG C, and keep the interior reaction of this temperature range 2 ~ 3 hours.The present invention uses and eco-friendly photocatalysis polymerization technique, and reaction condition is gentle, and production process is easily controlled, and product hydroxyl value is stable, and reactivity is big, even molecular weight distribution, and production cost is low. |
