Hydrogen Storage Capacity of Tetrahydrofuran and Tetra-N-Butylammonium Bromide Hydrates Under Favorable Thermodynamic Conditions

An experimental study was conducted to evaluate the feasibility of employing binary hydrates as a medium for H2 storage. Two reagents, tetrahydrofuran (THF) and tetra-n-butylammonium bromide (TBAB), which had been reported previously to have potential to form binary hydrates with H2 under favorable conditions (i.e., low pressures and high temperatures), were investigated using differential scan...

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...

Spectroscopic identification, thermodynamic stability and molecular composition of hydrogen and 1,4-dioxane binary clathrate hydrate

We present the spectroscopic identification of the binary hydrogen and 1,4-dioxane clathrate hydrates in which H2 molecules are encapsulated in small cages of the structure II hydrate framework. X-ray diffraction, solid-state NMR and Raman spectroscopy were used to confirm the mixed hydrate structure and more importantly the occupancy pattern of hydrogen in clathrate cages. The corresponding pr...

Kinetic 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...

Clathrate hydrogen hydrate--a promising material for hydrogen storage.

Hydrogen is viewed as a promising clean fuel of the future. A low-cost hydrogen storage technology that provides a high storage capacity and fast kinetics is a critical factor in the development of a hydrogen economy for transportation. The technologies to store hydrogen can be classified into three types: compression, liquefaction, and storage in a solid material. 2] Compressing hydrogen requi...
