Benzyltriethylammonium chloride (Bn[Et.sub.3]NCl, [greater than or equal to] 98%), used as a phase transfer catalyst, was also acquired from VWR (USA).
The mixture was heated at 100[degrees]C and benzyltriethylammonium chloride (0.05 moles Bn[Et.sub.3]NCl/mole -OH) was added.
First, when benzyltriethylammonium tetrafluoroborate was employed instead of the chloride salt, the yield of benzylated heterocycle in the case of 2-phenylindole (7) rose from 75% to 89% in less reaction time (3 h).
Adsorption of benzyltrimethylammonium and benzyltriethylammonium on montmorillonite: experimental study and model calculation.
Phthalic anhydride, p-aminophenol, p-toluenesulfonic acid, epichlorohydrin, benzyltriethylammonium chloride, phosphorous oxychloride, and 1, 3-propane diamine were purchased from S.
HPP (18.7 g) was mixed with 100 g of epichlorohydrin (ECH) in a 3-necked flask equipped with a stirrer, condenser, and a nitrogen inlet; to the above reaction mixture benzyltriethylammonium chloride (1.8 g) was added and the mixture was stirred under a nitrogen atmosphere for 24 h at 80[degrees]C.
The matrix reactive system is a stoichiometric mixture of diglycidyl ether of bisphenol A (DGEBA) and methyltetrahydroftalic anhydride (MTHPA) with a quaternary amine, benzyltriethylammonium chloride (BTEAC), added as initiator.
The [SiO.sub.2]-PMMA sample was vigorously stirred in a poly(ethylene) bottle containing 5 mL of toluene, 5 mL of a 10 wt% aqueous HF solution and 5 mg of benzyltriethylammonium bromide, used as a phase transfer catalyst.
Three series of solutions were used in this experiment: 1) 4 g PHBV was dissolved in 96 g chloroform with gentle stirring in a water bath of 60[degrees]C; 2) 4 g PHBV was dissolved in 72 g chloroform to form an original solution: 24 g alcohol, or tetrachloromethane, or N,N-dimethyl formamide was mixed into the original solution to yield a new solution with a concentration of 4 wt%; and 3) 1.73 g benzyltriethylammonium chloride (TEBAC) and 4 g PHBV was dissolved in 70.27 g chloroform to form an original solution: 24 g tetrachloromethane was mixed into the original solution to yield a new solution with a benzyltriethyl-ammonium chloride concentration of 1.73 wt% and polymer concentration of 4 wt%.
This effect also resembles that observed upon treatment of PANI-dinonylnaphthalene sulfonic acid films with benzyltriethylammonium chloride.
