A process for preparing oligo ethylene glycol methyl ether borate involves feeding boric acid and oligo ethylene glycol monomethyl ether into a reactor, and reacting to obtain a raw product containing oligo ethylene glycol methyl ether borate, water, and unreacted boric acid and oligo ethylene glycol monomethyl ether. The raw product is fed to a reactive distillation device and boric acid is reacted with oligo ethylene glycmonomethyl ether for full conversion of boric acid. A distillate stream containing water is transferred from the top of the reactive distillation device to a condenser, and a condensed liquid stream is recycled to the top of the reactive distillation device. A bottom product stream containing oligo ethylene glycol methyl ether borate is withdrawn from the reactive distillation device. The bottom product stream is partially recycled to a reboiler. The resulting vapor stream is recycled to the bottom of the reactive distillation device.

The invention relates to a process for the thermal decomposition of ammonia. The process comprises passing ammonia through a conduit which contains an ammonia decomposition catalyst in a part thereof. At least a section of the part of the conduit which contains the catalyst is immersed in molten lead as heat transfer medium, which is at a temperature at which the catalyst is capable of catalyzing the decomposition of ammonia into hydrogen and nitrogen. A reactor for carrying out this process is also disclosed.

A process for producing diazomethane of Formula 1 (CH.sub.2N.sub.2), with an automated apparatus is described. A stock solution of N-methyl-N-nitroso amine in an organic solvent is continuously flown and mixed with an aqueous inorganic base at a T-mixer to form a mixture. Then it is passed through a capillary micro reactor at a temperature in a range of 20 to 30° C. to form diazomethane. The mixture is separated into an aqueous layer and an organic layer using a continuous flow micro-separator. The organic layer has 0.1-0.4 M diazomethane. The organic layer is reacted with a carboxylic acid, phenol, an alkyne, an anhydride, a carboxyl metal organic framework (MOF), or MOF coated cotton to form a corresponding ester, a pyrazole, an ether, a diazo ketone, a stable carboxyl MOF or a stable MOF coated cotton fiber.
