the reaction between trimethylamine with propargyl bromide was studied and the structure of triethyl propargyl ammonium bromide was illustrated by 1hnmr, ir, and mass spectra.

biofiltration of triethylamine (tea) vapor used as a catalyst in casting operations was evaluated in this study. the unit consisted of a 6-l three-stage biofilter containing a mixture of compost and wood chips (40:60 v/v) as the filter medium. seed microbial population from municipal activated sludge was acclimated for a period of three weeks prior to the actual experimental runs. in the startu...

Effect of temperature on the chemiluminescence (CL) of Luminol in some aqueous aliphatic amines such as ethyl amine (EA), diethyl amine (DEA), and triethyl amine (TEA), have been studied and reported. On the basis of experimental results, it is found that the chemiluminescence intensity initially increased with temperature, attains an optimum value of particular temperature and then decrease on...

The title compound, C(11)H(8)ClN(3)OS, was prepared by the reaction of N-cyano-imino-thia-zolidine, 2-amino-ethanethiol and triethyl-amine at 350 K. The dihedral angle between the two rings is 62.5 (8)°.

the synthesis of functionalized 2-oxo-2h-coumarin derivatives has been studied by a one-pot reaction of o-hydroxybenzaldehyde, ethyl 2-bromoacetate and triphenylphosphine in the presence of catalytic amount of triethyl amine in etoac, water or under solvent free conditions. we have found the best results obtained under solvent free condition.

rearrangement of propargyl amine salt, in the presence of a base was studied and it was concluded that this occurs through an allenic intermediate.

Conformational studies with quantum chemical methods yielded for the most stable conformer of triethyl amine a propeller-like structure belonging to the point group C(3), which corresponds to an oblate top. The microwave spectrum of this conformer with (14)N hyperfine splitting of all rotational transitions was assigned and molecular parameters were determined. The rotational constants were fou...

The synthesis of functionalized 2-oxo-2H-coumarin derivatives has been studied by a one-pot reaction of o-hydroxybenzaldehyde, ethyl 2-bromoacetate and triphenylphosphine in the presence of catalytic amount of triethyl amine in EtOAc, water or under solvent free conditions. We have found the best results obtained under solvent free condition.

The title compound, C(11)H(16)Cl(4), was synthesized by the reaction of (1S)-β-pinene with triethyl-amine in the presence of ZnCl(2). The cyclo-hexene ring assumes a half-boat conformation. The crystal packing is governed only by van der Waals inter-actions. The structure, which has been refined in P2(1), presents a striking P2(1)/m pseudosymmetry.

A series of Nـ alkyl 2ـ ketomethylquinoline derivatives were synthesis by reaction of benzoyl chloride derivatives with Nـ methyl quinaldine iodide in the presence of triethyl amine under microwave irradiation. Enaminone form of the product study by spectroscopy method. The result revealed the  Nـ alkyl 2ـ ketomethylquinoline the fixed enaminone tautomer.
