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 A bottom product stream containing oligo ethylene glycol methyl ether borate is withdrawn from the reactive distillation device.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.
