Photolysis of Tris(ethylxanthato) Chromium (III) complex in DMSO
ISBN: 9783844331714 / Angielski / Miękka / 2011 / 92 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. In the present work we prepared tris(alkylxanthato)chromium(III) and intended to study the photochemistry of these complexes in dimethyl sulfoxide. These complexes might be useful in many applications. Moreover, metal chelate with metals at high oxidation state is active in the enhancement of photodegradation of plastic and therefore, might serve as photocatalyst to treat the plastic waste pollution problem. The effect of number of methyl group in these complexes has been also studied. This work also deals with the photochemical reaction and determination of quantum yields and reactivity...

Certain grades are industrially used and, together with carbohydrates and proteins, are important renewable resources compared to fossil and mineral raw materials, whose occurrence is finite. In concepts for new products, the price, performance, and product safety criteria are equally important and have a correspondingly high importance right at the start of product development. To ensure a high degree of product safety for consumers and the environment, renewable resources have often been shown to have advantages...
