Title (EN) A PROCESS FOR PREPARING POLYLYSINES
(FR) PROCÉDÉ DE PRÉPARATION DE POLYLYSINES
Abstract:
(EN) The present invention relates to a process for preparing a polylysine, comprising the steps of (a) heating a boiling aqueous reaction mixture comprising lysine and water in a weight ratio of 1:10 to 3:1 within 2 to 8 hours to a temperature in the range from 135 to 165 °C, and (b) keeping the reaction mixture of step (a) at a temperature in a range from 135 to 165 °C at a pressure below atmospheric pressure, wherein water is removed from the mixture, and any temperature increase is ≤ 30 °C in 60 minutes. The process is simple and suitable for large scale production of polylysine with improved yield.
(FR) La présente invention concerne un procédé de préparation d'une polylysine, comprenant les étapes consistant (a) à chauffer un mélange aqueux de réaction en ébullition comprenant de la lysine et de l'eau dans un rapport pondéral de 1:10 à 3:1, en 2 à 8 heures, à une température située dans la plage allant de 135 à 165 °C, et (b) à maintenir le mélange de réaction de l'étape (a) à une température située dans la plage allant de 135 à 165 °C à une pression inférieure à la pression atmosphérique, l'eau étant éliminée du mélange, et toute augmentation de température étant ≤ 30 °C en 60 minutes. Le procédé est simple et approprié pour une production à grande échelle de la polylysine avec un rendement amélioré.
