Density functional study of acrolein adsorption on Pt (111)
(Pergamon-Elsevier Science Ltd, 2014-01)
The electronic structure and bonding of acrolein (propenal) adsorption on Pt (111) were studied by density functional calculations (DFT). We optimized different adsorption configurations on the surface using the VASP code. ...
Irrigation of pepper plant (Capsicum sp.) with water containing acrolein
(Elsevier Science, 2004-07-01)
MAGNACIDE® H herbicide (a.i. acrolein (2-propenal)) is an aquatic herbicide applied through underwater injection into agricultural irrigation canals for the control of submerged aquatic weeds. In support of the products ...
Environmental and biological determination of acrolein using new cold fiber solid phase microextraction with gas chromatography mass spectrometry

The multiple benefits of glycerol conversion to acrolein and acrylic acid catalyzed by vanadium oxides supported on micro-mesoporous MFI zeolites
(2017-01-01)
The ZSM-5 zeolite (MFI structure, Si/Al = 40) was treated using NaOH and either oxalic acid or HCl to obtain hierarchical materials with different characteristics, followed by impregnation with vanadium oxides (V2O5) to ...
Efficiency of zeolite MCM-22 with different SiO2/Al2O3 molar ratios in gas phase glycerol dehydration to acrolein
(2013)
The gas-phase dehydration of glycerol was conducted over MCM-22 zeolite with different SiO2/Al2O3 molar ratios. MCM-22 zeolites were synthesized and characterized by XRD, FTIR, TG, SEM, EDX, textural analysis by N2 ...
Dehydration of glycerol to acrolein using H-ZSM5 zeolite modified by alkali treatment with NaOH
(Elsevier, 2014-11)
The dehydration of glycerol to acrolein has been studied using H-ZSM5 zeolite treated in alkaline medium in order to develop mesoporosity by desilication. Treatment of H-ZSM5 zeolite (Si/Al=15) in NaOH solutions leads to ...
Efficiency of zeolite MCM-22 with different SiO2/Al2O3 molar ratios in gas phase glycerol dehydration to acrolein
(Elsevier Science BvAmsterdamHolanda, 2013)
Factors affecting the efficacy of acrolein in irrigation channels in southern Argentina
(Wiley Blackwell Publishing, Inc, 2005-08)
Growth of the submerged weed Potamogeton pectinatus L. is a major problem in the irrigation channels located in the Lower Valley of the Colorado River (39 10¢–39 55¢S; 62 05¢–63 55¢W) in Argentina. Previous studies indicate ...
One-step glycerol oxidehydration to acrylic acid on multifunctional zeolite catalysts
(Elsevier B.V., 2015-02-25)
The catalytic behavior of bifunctional V2O5/MFI catalysts with acid and oxidizing properties was investigated for the gas-phase oxidehydration of glycerol. One of the main reaction products was acrylic acid, produced by ...
