    • A continuous process for the manufacture of a polyamide, the process comprising the steps of: (i) flowing a stream A comprising a moltendicarboxylic acid, or a molten dicarboxylic acid-rich mixture comprising a dicarboxylic acid and a diamine, through a first stage and at least one more reaction stage of a vertical multistage reactor, wherein the first stage is at the top of the reactor; (ii) counter-currently flowing a stream B comprising a diamine as either a vapour or a diamine-rich liquid through at least one of the stages below the first reaction stage of said vertical multistage reactor; (iii) accumulating a liquid phase material P comprising polyamide at and/or below the final stage of said reactor; wherein said reactor is equipped with internal features suitable for effecting contact between counter-currently flowing streams A and B; and wherein the process further comprises controlling the viscosity of said liquid phase material P by directly controlling the chemical equilibrium of the polyamidation reaction or by controlling stream B so that the amounts of diamine and dicarboxylic acid introduced into the reactor during the process are stoichiometrically imbalanced. The invention further provides a vertical multistage reactor configured to implement said process.

    • A process for converting polyhydric alcohols to monoalcohols in a counter current column reactor with a metal based catalyst supported on a porous membrane coated over a tubular system that delivers hydrogen where a hydrocarbon (low polarity) liquid solvent is fed at the bottom of the column reactor and an aqueous liquid having polyhydric alcohols therein is fed into the top of the reactor such that the aqueous liquid flows countercurrent to the low polarity solvent liquid and further wherein the low polarity solvent liquid is less dense than the aqueous liquid such that the two liquids are subject to phase separation. Monoalcohols are formed by hydrogenolysis reactions of polyhydric alcohols on the metal catalyst. Monoalcohols phase separate from the aqueous phase to the hydrocarbon solvent. Monoalcohols are further separated from the organic solvent.
