Chemistry and Chemical technology has contributed considerably to the development of abundant human life by providing various kinds of useful materials. Although there have been several adverse effects, the positive effects were dominate. As for the future, we are confident that chemical technology will continue to play key roles, but we can not foresee similar development as in the past, because of the limited supply of resources and the intolerable environmental disruption. The influences of science and technology might have grown beyond our controllability.The implementation of clean, eco–friendly, less energy and waste producing processes and technologies is realized today with an increasing interest. In order to provide a sustainable development, environmentally friendly substances, novel technologies and new green chemistry options should be utilized. In that respect, in this paper green chemistry, green engineering and their principles are reviewed in relation to green technologies for wastewater treatment.<\div>

۳A green, efficient, and rapid procedure for the synthesis of pyrano[3,2–c] quinoline and pyrano[3,2–c]pyridone derivatives catalyzed by [BMIm]Cl
اطلاعات انتشار: Iranian Journal of Catalysis، سوم،شماره۱، ۲۰۱۳، سال
تعداد صفحات: ۶
A highly practical and efficient preparation of pyrano[3,2–c]pyridone and pyrano[3,2–c]quinoline derivatives was developed via an ionic liquid mediated and promoted multi–component reaction of malononitrile, aldehyde, and 4–hydroxyquinolin–2(1H)–one or 4–hydroxy–6–methylpyridin–2(1H)–one. The combinatorial syntheses were achieved for the first time without applying extra activation energy at ambient temperature while making use of [BMIm]Cl as a catalyst solvent.

تعداد صفحات: ۶
The Brønsted acidic ionic liquid ([BMIm]HSO4) catalyzed three–component synthesis of 2H–indazolo[2,1–b]phthalazine–trione derivatives at room temperature. The integrity of the ionic liquid remains reasonably unchanged when it is separated from the reaction mixture by water extraction, as it can be recycled several times without any loss of activity in each of the title syntheses. The products and ionic liquid could be conveniently separated from the reaction mixture, indicating that the whole process was performed as a green chemical transformation. The salient features of this one pot protocol are short reaction times, cleaner reaction profiles and simple workup.
