| titleOfInvention | A method of preparing catalyst using phosphorus tailing or low grade collophanite |
| abstract | The invention belongs to chemical technology fields, disclose a kind of method preparing catalyst using phosphorus tailing or low grade collophanite, it is using gained phosphorus tailing or low grade collophanite after flotation of phosphate rock as raw material, raw material is washed, is dried, then coal is added and is fully ground to obtain mixed powder, catalyst precarsor is roasted to obtain, using after baking after acid solution or salt solution impregnation, drying up to the catalyst.Gained catalyst of the invention is in the reacting of urea and propylene glycol or glycolysis alcoholysis synthesizing acrylic ester or ethylene carbonate with preferable catalytic activity and selectivity; this method can provide new approaches to solve the processing problem of phosphorus tailing; and important facilitation is played to the industrialization of urea alcoholysis synthesis technology; the requirement for meeting industrial production and environmental protection, has a good application prospect. |
