摘要

Abstract

Polyurea microcapsules containing NiCl

were prepared by interfacial polymerization between diisocy-anate and water with triethylamine as a catalyst in water-in-oil emulsion system. The influence of preparation conditions such as the dosage and feed mode of the catalyst

concentration of the encapsulated NiCl

and concentration and structure of diisocyanates on the breakage of the microcapsules have been evaluated. The results show that breakage is strongly dependent on the rate of polymerization and stability of initial emulsion. The improved micro-capsules with low breakage have been produced under the optimum conditions. Furthermore

the obtained micro-capsules immobilizing NiCl

as a recyclable catalyst is successfully used in benzaldehyde reduction.
