| titleOfInvention | Molecular sieve type solid alkali catalyst and preparation method thereof |
| abstract | The invention relates to a molecular sieve type solid alkali catalyst and a preparation method thereof. The chemical general formula of the molecular sieve type solid alkali catalyst provided by the invention is Ln(PO2NH)3, wherein the Ln is a rare-earth element. The preparation method of the molecular sieve type solid alkali catalyst Ln(PO2NH)3 provided by the invention comprises the following steps: enabling a sodium acetate aqueous solution and a hexachlorocyclotriphosphazene dioxane solution to react and obtaining nitrogen phosphate Na3(PO2NH)3; and enabling a Na3(PO2NH)3 aqueous solution and a rare-earth chloride ethanol solution to react and obtaining the Ln(PO2NH)3. The catalyst provided by the invention has the advantages of high stability and simplicity in preparation method. The catalyst provided by the invention shows good alkali catalytic activity on a Knoevenagel condensation reaction of benzaldehyde and ethyl cyanoacetate; the conversion rate of the ethyl cyanoacetate is 61-66%; and the selectivity of a reaction product, namely alpha-cyanoethyl cinanmate is 100%. |
