Abstract

Procedimento per la preparazione di esteri alchilici da oli vegetali trigliceridi naturali mediante trans esterificazione, in presenza di catalizzatori alcalini con alcoli a basso peso molecolare in cui il sistema viene mantenuto ad una pressione tale che la miscela di reazione sia allo stato liquido, ad un pH di almeno 10 ed in condizioni di flusso longitudinale, acidificando a fine reazione e separando la glicerina formatasi nella reazione.Process for the preparation of alkyl esters from natural triglyceride vegetable oils by trans esterification, in the presence of alkaline catalysts with low molecular weight alcohols in which the system is maintained at a pressure such that the reaction mixture is in the liquid state, at a pH at least 10 and under longitudinal flow conditions, acidifying at the end of the reaction and separating the glycerin formed in the reaction.
