Tetra-N-Butyl ammonium hydroxide mediated one-pot synthesis of pyrano [2, 3-d] pyrimidinone Derivatives
Tetra-N-Butyl Ammonium Hydroxide was used as a catalyst for one-pot, three component condensation reactions consisting of aromatic aldehydes, malononitrile and barbituric acid in ethanol:water solvent system at 60oC. Current method has major advantages like mild reaction conditions with simple operation, high yields, by using a less toxic and lower costlier catalyst.In conclusion, we have explo...
متن کاملKinetic study of cis-polybutadiene epoxidation by using 1HNMR spectroscopy in buffered oxone® solution with tetra-n-butyl ammonium bromide as phase transfer catalyst (PTC)
Cis-polybutadiene was functionalized using in–situ generated DMD as oxidant and tetra-n-butyl ammonium bromide as phase transfer catalyst (PTC). The epoxidation process was investigated by 1HNMR spectroscopy. 1HNMR spectrum analysis of products confirms the absence of ring opening side products in epoxidation reaction. Various factors such as reaction temperature, reaction time and the concentr...

متن کاملTetra-n-propylammonium chloride monohydrate
The crystal structure of the title salt hydrate, C(12)H(28)N(+)·Cl(-)·H(2)O, consists of non-inter-acting cations and anions. The water mol-ecule forms hydrogen bonds to two chloride ions, about a center of inversion, generating a planar eight-membered {⋯H-O-H⋯Cl}(2) ring.
متن کاملSolvent Extraction of Tellurium from Chloride Solutions Using Tri-n-butyl Phosphate: Conditions and Thermodynamic Data
The extractive separation of tellurium (IV) from hydrochloric acid media with tri-n-butyl phosphate (TBP) in kerosene was investigated. The dependence on the extraction of tellurium species, concentrations of tellurium and TBP, extraction time and stage, organic/aqueous ratio, and interferences from coexist metallic ions were examined and are discussed. Besides, the stripping agent and strippin...
