Abstract

Zgłoszenie dotyczy sposobu otrzymywania liniowych biopolioli poliestrowych, który polega na tym, że w pierwszym etapie kwas bursztynowy pochodzenia naturalnego miesza się z 1,3-propanodiolem pochodzenia naturalnego albo 1,4-butanodiolem pochodzenia naturalnego albo mieszaniną 1,3-propanodiolu pochodzenia naturalnego z 1,4-butanodiolem pochodzenia naturalnego zachowując stosunek molowy obu glikoli w zakresie od 1:1 do 1:5, przy czym stosuje się nadmiar glikolu lub mieszaniny glikoli tak aby stosunek molowy kwasu bursztynowego do glikolu lub mieszaniny glikoli we wszystkich przypadkach wynosił od 1:1,05 do 1:1,40, Następnie uzyskaną mieszaninę ogrzewa się w pierwszym etapie przez od 5 do 10 godzin w temperaturze od 140 do 180°C w atmosferze gazu obojętnego do momentu uzyskania co najmniej 60% mas. wody w przeliczeniu na ilość teoretyczną, jako produktu ubocznego. Następnie przeprowadza się drugi etap, czyli polikondensację w ten sposób, że mieszaninę ogrzewa się do temperatury od 160 do 220°C i reakcję prowadzi się pod obniżonym ciśnieniem, zaś proces polikondensacji prowadzi się do momentu osiągnięcia przez produkt liczby kwasowej mniejszej od 3 mg KOH/g.The application relates to a method of obtaining linear polyester biopolies, which consists in the first stage of mixing succinic acid of natural origin with 1,3-propanediol of natural origin or 1,4-butanediol of natural origin or a mixture of 1,3-propanediol of natural origin with 1 , 4-butanediol of natural origin, maintaining a molar ratio of both glycols in the range of 1: 1 to 1: 5, with an excess of glycol or a mixture of glycols being used so that the molar ratio of succinic acid to glycol or a mixture of glycols in all cases is from 1: 1 , 05 to 1: 1.40, The resulting mixture is then heated in a first step for 5 to 10 hours at a temperature of 140 to 180 ° C under an inert gas atmosphere until at least 60% by mass is obtained. water calculated as the theoretical amount as a by-product. Then the second stage is carried out, i.e. polycondensation in such a way that the mixture is heated to a temperature of 160 to 220 ° C and the reaction is carried out under reduced pressure, while the polycondensation process is carried out until the product reaches an acid number less than 3 mg KOH / g.
