Facile Synthesis of Nitriles and Amides from Aldehyde over Heterogeneous Reusable Copper Fluorapatite (CuFAP) Catalyst under Neat Reaction Condition
Open Journal of Synthesis Theory and Applications, 2017Co-Authors: Santosh S. Chavan, Mohsinkhan Y. Pathan, Taufeekaslam M. Y. Shaikh, Shafeek A. R. MullaAbstract:A new robust heterogeneous, versatile, an environmentally benign, eco-friendly, recyclable CuFAP catalyst has been developed for the direct synthesis of nitriles and amides from aldehydes at 100°C for 6 h and 4 h, respectively, under neat Reaction Condition using hydroxylamine hydrochloride in the presence and the absence of tosyl chloride, respectively. Also the recyclability of catalyst as well as influence of solvents, additives on catalysts performance was investigated. The protocol can be considered as an alternative to conventional method for the synthesis of nitriles and amides in good to excellent yields. A highlight of our protocol is the easy separation of catalyst from Reaction mixture, hence the catalyst is reused several times without significant loss of its catalytic activity.

development of a Reaction cell for in situ operando studies of surface of a catalyst under a Reaction Condition and during catalysis
Review of Scientific Instruments, 2016Co-Authors: Luan Nguyen, Franklin Feng TaoAbstract:Tracking surface chemistry of a catalyst during catalysis is significant for fundamental understanding of catalytic performance of the catalyst since it allows for establishing an intrinsic correlation between surface chemistry of a catalyst at its working status and its corresponding catalytic performance. Ambient pressure X-ray photoelectron spectroscopy can be used for in-situ studies of surfaces of different materials or devices in a gas. To simulate the gaseous environment of a catalyst in a fixed-bed a flowing gaseous environment of reactants around the catalyst is necessary. Here, we report the development of a new flowing Reaction cell for simulating in-situ study of a catalyst surface under a Reaction Condition in gas of one reactant or during catalysis in a mixture of reactants of a catalytic Reaction. The homemade Reaction cell is installed in a high vacuum (HV) or ultrahigh vacuum (UHV) environment of a chamber. The flowing gas in the Reaction cell is separated from the HV or UHV environment t...

Surface of a catalyst in a gas phase
Current Opinion in Chemical Engineering, 2016Co-Authors: Yu Tang, Luan Nguyen, Nan Wang, Franklin Feng TaoAbstract:Chemistry and structure of surface of a catalyst under a Reaction Condition is the crucial information for understanding catalytic mechanism since in many cases an authentic, active surface catalyzing a catalytic Reaction is formed in a pretreatment or/and in a Reaction between nominal catalyst and reactants. Ambient pressure X-ray photoelectron spectroscopy can be used to track surface of a catalyst under a Reaction Condition as the instrumentations in the last a few decades have made characterization of catalyst surface in a gas phase at Torr pressure or higher possible. It can characterize surface chemistry of a catalyst including surface composition, surface phase and surface oxygen vacancies and other information under a Reaction Condition and track their evolutions when the Reaction Condition is changed to another.
