Study on the synthesis of ethylparaben with solid superacid SO_4~(2-)/TiO_2-attapulgite as catalyst;

Simultaneous Determination of Two Components in Compound Ethylparaben Alcoholic Solution by HPLC;

The Paper studied the making of antibacterial paper by surface spraying of the following three bactericides:organic bactericide nipagin esters,inorganic bactericide copper sulfate and natural bactericide chitin.

Nd 2O 3 used as solid catalyst for the preparation of nipagin esters with p hydroxybenzoic acid and alcohol has been studied.

Comparison of the addition of paraben and sodium benzoate in sauce/vinegar;

Research development on the synthesis of paraben

The usage of complex paraben as antiseptic has the advantage of extensive pH and high restrain microbe ability in the food field .

Comparison on anticorrosive Nipagin esters in soy sauce and sauce;

Preparation of nano solid superacid SO_4~(2-)/Fe_2O_3 used as a catalyst to synthesize nipagin esters;

It showed that this catalyst was reused and regenerated,and excellent one for the synthesis of Nipagin esters.

This paper introduces the properties, applications and syntheses of Nipagin ester, and its production situation at home and abroad.
