Study of enzymatic production of biodiesel using vegetable oils and commercial ethanol
Abstract
Biodiesel is a combination of alkyl fatty acid esters generated by a catalyst and supported by acid, basic, or enzymatic processes from vegetable oils to short-chain alcohols such as ... Read MoreSynthesis, characterization and evaluation of 5-alkylidene meldrum’s acid derivatives as multifunction lubricating oil additives
Abstract
A series of 5-alkylidene Meldrum's acid derivatives were prepared by Knovenagel condensation of Meldrum's acid with different aldehydes in the presence of pipridin as a catalyst. The ... Read MoreHydrothermal synthesis and characterization of zinc sulfide nanoparticles
Abstract
Zinc sulfide NPs are well-known as excellent photo catalyst because of their unique optical properties such as band gap energy, retention time, the high light absorption, electron-hole ... Read MoreSynthesis of pyranopyrazole and pyranopyrimidine derivatives using magnesium oxide nanoparticles and evaluation as corrosion inhibitors for lubricants
Abstract
