an extensive study of higher alcohols synthesis (has) from syngas using alkalized mos2 catalysts supported on carbon nanotubes (cnts) is reported. up to 30wt.% of mo and 8wt.% k are added to the cnts by impregnation method. the catalysts were characterized by different methods and the performance of the catalysts was assessed in a micro-reactor. tem images showed that most of the metal particle...

an extensive study of higher alcohol synthesis (has) from synthesis gas using cobalt (co) promoted alkalized mos2 catalysts supported on carbon nanotubes (cnts) is reported. up to  5wt.% of co is added to the 15wt.% mo-wt.%k/ cnts by incipient wetness impregnation method. most of the metal particles were homogeneously distributed inside the tubes and the rest on the outer surface of the cnts. t...

a general, mild and efficient protocol has been developed for the synthesis of esters and thioesters. the process has been taking place using tetra n-butylammonium iodide (tbai) as a phase-transfer catalyst and in the presence of potassium carbonate (k2co3). a wide range of esters and thioesters was prepared in high yields and suitable times by the treatment of alcohols, phenols and thiols with...

An extensive study of Higher Alcohols Synthesis (HAS) from syngas using alkalized MoS2 catalysts supported on Carbon Nanotubes (CNTs) is reported. Up to 30wt.% of Mo and 8wt.% K are added to the CNTs by impregnation method. The catalysts were characterized by different methods and the performance of the catalysts was assessed in a micro-reactor. TEM images showed that mo...

An efficient tandem synthesis of alkyl aryl ethers, including valuable building blocks of dialdehyde and dinitro groups under microwave irradiation and solvent free conditions on potassium carbonate as a mild solid base has been developed. A series of alkyl aryl ethers were obtained from alcohols in excellent yields by following the Williamson ether synthesis protocol under practical mild condi...

the influence of mo particle size on the catalytic activity and product selectivity of alkalized mos2 nanocatalysts has been investigated. nanocatalysts are prepared using a microemulsion technique with water-to-surfactant ratios of 1-12. three different techniques, including xrd, tem, and hydrogen chemisorption were used to determine the molybdenum average particle size and their activity and ...
