The effect of intermittent light on the rate of a chain reaction involving iodine atoms has been used to measure the average life-time of photochemically produced iodine atoms between about 15 and 35 deg in hexane, carbon tetrachloride and hexachloro

The acid dissociation constants were determined potentiometrically for benzimidazole, 2-methylbenzimidazole and 2-ethylbenzimidazole in solutions of ionic strength 0.16 M (NaNO/sub 3/) at4 plus or minus 1, 25 plus or minus .1, and 35 plus or minus 0.

The reduction has been effected by using a variety of Pd (palladium)-based catalysts. The typical procedure was to suspend 0.25 g of catalyst in 25 cc of an aqueous solution of sodium bicarbonate purged slowly with hydrogen gas. The sodium formate co

Deuterium gas exchanges slowly with liquid methanol over Raney nickel catalyst at 35 deg . The reaction is zero order with respect to deuterium pressure and has a low activation energy. The influences of catalyst weight, catalyst treatment, and of th

The key requirement for a portable store of natural gas is to maximize the amount of gas within the smallest possible space. The packing of methane (CH4) in a given storage medium at the highest possible density is, therefore, a highly desirable but

Two metal–organic framework materials, MFM-130 and MFM-131 (MFM = Manchester Framework Material), have been synthesized using two oligoparaxylene (OPX) tetracarboxylate linkers containing four and five aromatic rings, respectively. Both fof-type no

A turbulent flow apparatus was used for qualitative study of the exchange of N/sup 15/H/sub 3/ between solvent and ligands in complex metal ammines. The N/sup 15/-enriched liquid NH/sub 3/ was mixed in approximately O.O1 sec with an unenriched soluti
