processos para a produção de um éster e de um poliéster a partir de uma pluralidade de reagentes, e, aparelho para preparar pelo menos um monÈmero de éster, um oligÈmero de éster ou um poliéster.

摘要

A process for introducing a component into a reaction fluid and/or process fluid comprising the steps of: (a) providing a recirculation loop having a influent and an effluent wherein the influent is in fluid communication with a reaction fluid; (b) recirculating at least a portion of the reaction fluid of step (a) through the recirculation loop wherein the reaction fluid flowing through the circulation loop is a recirculation fluid; (c) decreasing the pressure of the recirculation fluid of step (b) with at least one pressure decreasing device at at least one point in the recirculation loop; and (d) feeding a component into the recirculation loop adjacent to or at the pressure decreasing device of step (c), to thereby introduce a component into the reaction fluid.
