Catalyst- and solvent-free hydrophosphination and multicomponent hydrothiophosphination of alkenes and alkynes
(Royal Society of Chemistry, 2016-05-26)
The hydrophosphination of carbon-carbon multiple bonds has been generally performed under acid, base or metal catalysis in different solvents. Herein, alkyl and alkenyl tertiary phosphines are obtained by the addition of ...
Methane combustion over Pd/SiO2 catalysts with different degrees of hydrophobicity
(ELSEVIER SCIENCE BV, 2005-04-08)
The combustion of methane has been studied over 1% Pd catalysts supported on commercial silica with different hydrophobicity, prepared by chlorine free precursors. It was found that, when no water is added to the feed, the ...

Heterogeneous esterification of oil with high amount of free fatty acids
(Elsevier, 2007-03)
Frying oils have become the newest raw material for the transesterification reaction for the production of biodiesel. However, these compounds usually come with a certain amount of free fatty acids. These impurities can ...
Efficient microwave-assisted esterification reaction employing methanesulfonic acid supported on alumina as catalyst
(Taylor & Francis, 2014-01)
A rapid and efficient protocol assisted by microwave irradiation for the synthesis of esters using methanesulfonic acid (CH3SO3H) supported on Al2O3 (AMA) as catalyst and free of solvent is described. The products were ...
