The catalytic activity for carboxylic esterification was characterized by XRD,DTA,TG,SSA,NH 3-TPD and ICP.

Three Schiff base cobalt(Ⅱ) complexes containing benzoaza-15-crown-5,CoL1,CoL2 and CoL3 were used in catalytic hydrolysis of carboxylic ester (PNPP,p-nitrophenyl picolinate) as mimic hydrolytic metalloenzyme at pH 7.

Complexes of the Schiff base with morpholino or aza-crown pendants,CoL1 and CoL2,as mimic hydrolytic metalloenzyme,were used in catalytic hydrolysis of carboxylic ester(PNPP) at pH7.

Recent research progresses in the synthesis of carboxylic ester by phase transfer catalyst such as hexadecy trimethylammonium chloride/bromide and tetrabutylammonium chloride/bromid were reviewed.
