TAILIEUCHUNG - Synthesis of allyl-glycidyl ether by the epoxidation of diallyl ether with t-butyl hydroperoxide over the Ti-MWW catalyst

In this paper, modified hydrothermal method for Ti-MWW catalyst preparation has been shown. Instrumental analysis of the zeolite material Ti-MWW has been performed by means of UV-vis spectrometry, infrared spectrometry (IR), scanning electron microscope (SEM), X-ray diffraction (XRD), and X-ray microanalysis. | Synthesis of allyl-glycidyl ether by the epoxidation of diallyl ether with t-butyl hydroperoxide over the Ti-MWW catalyst Current Chemistry Letters 6 2017 7 14 Contents lists available at GrowingScience Current Chemistry Letters homepage Synthesis of allyl-glycidyl ether by the epoxidation of diallyl ether with t-butyl hydroperoxide over the Ti-MWW catalyst Agnieszka Wróblewskaa Marika Walaseka and Beata Michalkiewiczb a West Pomeranian University of Technology Szczecin Institute of Organic Chemical Technology Pulaskiego 10 70-322 Szczecin Poland b West Pomeranian University of Technology Szczecin Institute of Inorganic Chemical Technology and Environment Engineering Pulaskiego 10 70- 322 Szczecin Poland CHRONICLE ABSTRACT Article history In this paper modified hydrothermal method for Ti-MWW catalyst preparation has been Received August 21 2016 shown. Instrumental analysis of the zeolite material Ti-MWW has been performed by means Received in revised form of UV-vis spectrometry infrared spectrometry IR scanning electron microscope SEM X- October 24 2016 ray diffraction XRD and X-ray microanalysis. Moreover the results of the epoxidation of Accepted 8 November 2016 diallyl ether DAE over the titanium silicate catalyst Ti-MWW and in the presence of Available online methanol have been presented. t-Butyl hydroperoxide have been applied for the first time as 9 November 2016 an oxidant for this process. The influence of temperature 20-130 C DAE TBHP molar ratio Keywords 1 1-3 1 methanol concentration 10-80 wt amount of catalyst 1-7 wt and reaction Diallyl ether time 60-1440 min. was studied. The main functions describing the process were determined Allyl-glycidyl ether on the basis of the results obtained from the gas chromatography method.
