There are disclosed a process for producing methyl formate by dehydrogenating methanol in liquid phase in the presence of a solid catalyst and a process according thereto wherein a gas (N.sub.2, H.sub.2, CO, etc.) is continuously blown into the liquid phase from outside, and the gas along with the reaction product are continuously withdrawn outside the reaction system from the gaseous phase directly or through a cooler. By virtue of the liquid-phase reaction in the above process, as compared with the conventional gaseous phase reaction, the reaction temperature can be lowered, the reaction gas rich in the objective methyl formate rather than methanol is obtained by continuously withdrawing the resultant methyl formate outside the reaction system and accordingly, a single pass yield higher than that at the thermodynamical equilibrium-value is assured, whereby energy saving is made possible.

Process for producing methyl formate

Disclosed is a process for producing neopentyl glycol which comprises hydrogenating hydroxypivaldehyde in the presence of a catalyst comprising copper, zinc and zirconium. The catalyst has a high catalytic activity and a long service lifetime.

A process for producing 2,6-dimethylnaphthalene, which comprises subjecting 2-methyl-1-(p-tolyl)-butene, 2-methyl-1-(p-tolyl)-butane or a mixture of these to cyclization and dehydrogenation in the presence of a catalyst comprising lead oxide and/or indium oxide and aluminum oxide.

Process for producing 2,6-dimethylnaphthalene

A catalyst composition for decomposition of methanol comprising a substantially aluminum-free precipitate composed of a copper compound and a nickel compound, a phosphate salt of aluminum and an alkali metal compound, the content of the alkali metal being 1 to 100 atoms per 100 atoms in total of copper and nickel in the precipitate.

Catalyst composition for decomposition of methanol

A condensed liquid obtained after separation of gaseous components from the gas produced by the steam reforming reaction of methanol is brought into contact, in a gaseous phase, with catalyst (I) containing copper oxide (A), oxide of at least one type of metals selected from the group consisting of zinc, aluminium and chromium (B) and oxide of the group VIII metal in the periodic table (C), or catalyst (II) comprising the group VIII metal in the periodic table or compound thereof supported on carriers. The treatment of the condensed liquid yields water containing substantially no methanol, ethanol and high boiling point components. The treated condensed liquid causes no pollution problem when disposed as effluent and may be reused for the steam reforming reaction of methanol.
