N, N-dimethylaminoethyl ethylphosphonic acid-zirconium hydrogenphosphate was used as a carrier and treated with 5% NaOH solution to obtain the solid base. Elemental analysis, IR, TG, DTG, DTA, BET surface area, Alkalinity determination of solid base was characterized by the indicator method to measure the alkali strength of 9.3 to 15.0, and the commonly used solid sodium carbonate base intensity is equivalent to benzoic acid titration method to measure the amount of alkali base, discuss the carrier of organic phosphine The relative content of acid, holding time on the alkaline, solid base for catalytic Knoevenagel condensation reaction, a high catalytic activity, high yield of the product, fewer side reactions, reusable 6 to 7 times, and easy to regenerate , Is a new environmentally friendly green catalyst.
