Abstract:
    An apparatus and a method for carrying out the dehydration reaction to produce a high boiling compound comprises charging a raw material and an organic solvent into a circulating system including a reactor, a preheater and an evaporator to cause the chemical dehydration reaction, drawing water, formed as a result of the dehydration reaction, together with the solvent in the form of vapor, compressing the vapor, effecting a heat exchange between the compressed vapor and the evaporator, dehydrating the compressed vapor by condensation, removing the dehydrated water out of the system, and returning the remaining solvent to the reactor.
