Maleic anhydride incorporated onto cellulose and thermodynamics of cation-exchange process at the solid/liquid interface
(Elsevier Science BvAmsterdamHolanda, 2009)
Cr, Mo and W used as VPO promoters in the partial oxidation of n-butane to maleic anhydride
(Elsevier Science, 2005-10)
The present work addresses the issue of the promoter effect produced by group VIB elements added to the basic VPO formulation using different methods and loads in order to obtain information linking the catalytic behavior ...
Hydrogenation of Maleic Anhydride in Gas Phase on Cu and Ni Supported Catalysts: Effect of The Support and Method of Preparation
(Executive Bussiness School, 2012-03)
Se estudió la hidrogenación de anhídrido maleico en fase gas empleando catalizadores de Cu y/o Ni, soportados sobre SiO2 y SiO2-Al2O3, preparados por impregnación a humedad incipiente y precipitación-deposición. La carga ...
Melt grafting of itaconic acid and its derivatives onto an ethylene-propylene copolymer
(ELSEVIER SCIENCE BV, 2005-09)
An ethylene-propylene copolymer (EPR) was functionalized in the melt by grafting with itaconic acid and its mono- and di-methyl esters by using dicumyl peroxide as radical initiator. Grafting reactions were carried out in ...
Modification of poly(propylene) through grafting with dimethyl itaconate in solution
(WILEY-V C H VERLAG GMBH, 1998-11)
Functionalization of isotactic poly(propylene) (PP) with dimethyl itaconate (DMI) as functional polar monomer using 2,5-dimethyl-2,5 -bis(tert-butylperoxy)hexane (L101) as radical initiator was carried out in both boiling ...
In vitro antimicrobial efficiency of a mouthwash containing triclosan/gantrez and sodium bicarbonate
(2007-12-31)
Several antiseptic substances have been used as adjuncts to routine mechanical procedures of oral hygiene, based on their antimicrobial effects. The objective of this study was to assess in vitro the antimicrobial efficiency ...
