50 mg of catalyst, 50 mmol of DMSO, 50 mmol of methanol, temperature at 70 degrees C and 4 h duration was the optimized condition to achieve 100% methanol conversion and 98% selectivity of formaldehyde. The reaction pathway of methanol to formaldehyde conversion is discussed.Sukumar, M....
1.Researches in synthesis of anhydrous formaldehyde via methanol dehydrogenation;甲醇脱氢制无水甲醛的研究进展 2.The reaction conditions of methanol dehydrogenation to water-free formaldehyde was studied in a 16mm diameter fixed bed ceramic tube reactor,using Na_2CO_3 as catalyst,which was prepared by...
A new bifunctional catalyst comprising of CeO2 and SSZ-13 physical mixture was developed, and its lifetime for the methanol to olefins (MTO) reaction was significantly enhanced. Formaldehyde adsorbed on ceria forms formate species, which decomposes to CO or CO2. The formaldehyde decomposition by Ce...

Nano-structured iron molybdate materials, comprising Fe2(MoO4)3 nano-particles anchored onto MoO3 nano-rods, have been synthesised and evaluated as catalysts for the selective oxidation of methanol to formaldehyde. The catalysts were benchmarked against a standard iron molybdate catalyst prepared by co...

as it may be produced from renewable resources and has an energy density that allows demanding long-distance transport without refueling. Methanol is also an excellent precursor for making many bulk chemicals including olefins, formaldehyde, acetic acid, methyl chloride, DME, dimethyl terephthalate, ...
