    Abstract: 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.

    Abstract: This document describes biochemical pathways for producing 7-hydroxyheptanoic acid using a polypeptide having monooxygenase activity to form a 8-hydroxynonanoate intermediate, which can be converted to 7-hydroxyheptanoate using a polypeptide having monooxygenase activity, a polypeptide having secondary alcohol dehydrogenase activity, and a polypeptide having esterase activity. 7-hydroxyheptanoic acid can be enzymatically converted to pimelic acid, 7-aminoheptanoic acid, heptamethylenediamine or 1,7 heptanediol. This document also describes recombinant hosts producing 7-hydroxyheptanoic acid as well as pimelic acid, 7-aminoheptanoic acid, heptamethylenediamine and 1,7 heptanediol.
