Alkylation of N-substituted-2-phenylacetamides / Alkilovanje n-supstituisanih 2-fenilacetamida
(Serbian Chemical Society, Belgrade, 2004)
Various N-substituted phenylacetamides were alkylated using different alkylating agents under neutral and basic conditions. Reactions were performed at different reaction temperatures and in various solvents. Also, a number ...
Biodiesel synthesis using K2CO3/Al-O-Si aerogel catalysts / Sinteza biodizela katalizovana alumosilikatnim aerogelom sa K2Co3
(Serbian Chemical Society, Belgrade, 2010)
In this study, catalysts for fatty acid methyl esters (FAME or biodiesel) synthesis with K2CO3 as the active component on an alumina/silica support were synthesized using the sol-gel method, which was followed by drying ...
Removal of organochlorine pesticides from water using virgin and regenerated granular activated carbon / Uklanjanje pesticida iz vode na granulisanom aktivnom uglju
(Serbian Chemical Society, Belgrade, 2010)
Public water systems use granular activated carbon in order to eliminate pesticides. After saturation, the used activated carbon is regenerated and reused in order to reduce the costs of water production and minimize waste. ...
