Advances in Chemistry Research. Volume 62 e-bog

Advances in Chemistry Research. Volume 62 first provides information related to the synthesis, morphology, crystal structure, and porosity of bentonite and bentonite/magnetite powders. Following this, the authors discuss carbon tetrachloride, a clear, colourless, volatile and very stable chlorinated hydrocarbon with a non-polar nature, making it an excellent solvent. Recent research on the applications of hydrogen peroxide as oxidizing and reducing agent is presented, as well as its application in biocatalysis, as signaling molecule, and in nanochemistry. The mode of action hydrogen peroxide induces in yeast apoptosis is also addressed, including overexpression of apoptosis inducing factor homologue proteins. Additionally, this compilation describes the recent advances concerning the use of hydrogen peroxide in heteropolyacid-catalyzed oxidation reactions of terpenic alcohols, which are renewable origin compounds whose oxidation provides aldehydes and epoxides. Diamines, organic compounds with two amino groups, are described. In one study, different diamines are synthesized with complex formulas used in the preparation of different thermally stable polymers. A few diamines used in developing thin-film polyamide composite membranes are reviewed. The concluding study is focused on gas hydrates, mixtures of light gases such as methane, ethane or carbon dioxide, and water molecules under a special temperature and pressure condition, forming a liquid-like material.
