A series of 1-aryl-1,2-dihydrobenzo[f]quinolin-3(4H)-one derivatives were synthesized by a three-component one-pot reaction of benzaldehyde,naphthalene-2-amine and meldrum’s acid at refluxing temperature catalyzed by triethylbenzylammonium chloride in water.

The title compound C24H22N2O2 has been synthesized by the reaction of N-arylidenenaphthalen-2-amine with 5,5-dimethyl-1,3-cyclohexadione water catalyzed by triethylbenzylammonium chlorideTEBAC.

The title compound C_(25)H_(22)ClNO has been synthesized by the reaction of N-arylidenenaphthalen-2-amine with 5,5-dimethyl-1,3-cyclohexadione in water catalyzed by triethylbenzylammonium chloride(TEBAC).

Inhibitory kinetic spectrophotometric determination of trace nickel in Ni(Ⅱ)-KBrO_3-methyl violet system with benzyl triethylammonium chloride as enhanced sensitivity agent;

The method is based on the catalytic effect of iron(Ⅲ) on oxidation of bromocresol green by hydrogen peroxide(H_2O_2) using cationic surfactant of benzyl triethylammonium chloride(BTEAC) as sensitizer.

The reactions were carried out in presence of benzyl triethyl ammonium chloride(BTEAC),and through ring-opening,rearrangement and hydration successively.

In this paper,1,3- propanediol is synthesized using anhydrous sodium acetate,3- bromo- 1- chloropropane,anhydrous methanol,benzyl triethyl ammonium chloride and anion exchange resin etc.
