Characterization of carbon monoxide, methane and nonmethane hydrocarbons in emerging cities of Saudi Arabia and Pakistan and in Singapore [PDF]
We investigate the composition of 63 C2-C10 nonmethane hydrocarbons (NMHCs), methane (CH4) and carbon monoxide (CO), in Jeddah, Mecca, and Madina (Saudi Arabia), in Lahore, (Pakistan), and in Singapore. We established a database with which to compare and

Asymmetric synthesis of 2-substituted oxetan-3-ones via metalated SAMP/RAMP hydrazones [PDF]
2-Substituted oxetan-3-ones can be prepared in good yields and enantioselectivities (up to 84% ee) by the metalation of the SAMP/RAMP hydrazones of oxetan-3-one, followed by reaction with a range of electrophiles that include alkyl, allyl, and benzyl ...

INCREASING THE EFFECTIVENESS OF STABILIZATION COLUMNS IN THE OIL AND GAS INDUSTRY
According to the results of the study, we found that increasing the pressure in a stabilization column improves the sharpness of separation of butanes from pentanes. As a result, the product quality is getting better.

A five year record of high-frequency in situ measurements of non-methane hydrocarbons at Mace Head, Ireland [PDF]
Continuous high-frequency in situ measurements of a range of non-methane hydrocarbons have been made at Mace Head since January 2005. Mace Head is a background Northern Hemispheric site situated on the eastern edge of the Atlantic. Five year measurements

Synthesis and Characterization of Three-Coordinate Ni(III)-Imide Complexes [PDF]
A new family of low-coordinate nickel imides supported by 1,2-bis(di-tert-butylphosphino)ethane was synthesized. Oxidation of nickel(II) complexes led to the formation of both aryl- and alkyl-substituted nickel(III)-imides, and examples of both types ...

Factors affecting the extent of branching in fischertropsch synthesis products with iron-based catalysts [PDF]
Branched products are mainly formed during secondary isomerization reactions, and not in the main synthesis reaction itself. The extent of branching is a function of the catalyst formulation. High acidity and a low hydrogenation strength of the catalyst (
