Abstract
Przedmiotem zgłoszenia jest sposób otrzymywania środków przeciwstarzeniowych do elastomerów. Sposób ten charakteryzuje się tym, że prowadzi się dwuetapową reakcje podczas której: w pierwszym etapie ogrzewa się kalafonię sosnową do temperatury od 170 do 190°C i przetrzymuje się w tej temperaturze w atmosferze gazu obojętnego przez co najmniej 4 godziny, a następnie dodaje się bezwodnik maleinowy i prowadzi się reakcję addycji bezwodnika maleinowego do kwasów żywicznych prowadzi się reakcję addycji bezwodnika maleinowego do kalafonii sosnowej. Reakcję prowadzi się w temperaturze od 160 do 200°C w atmosferze gazu obojętnego, przez co najmniej 6 godzin, po czym mieszaninę reakcyjną ochładza się do temperatury od 120 do 140°C. W drugim etapie prowadzi się reakcję otrzymanych adduktów ze związkiem zawierającym co najmniej jedną pierwszorzędową grupę aminową takich jak: anilina lub 4,4'-diaminodifenylometan lub trietylenotetramina lub aminowa pochodna zdimeryzowanych kwasów tłuszczowych. Reakcję prowadzi się w temperaturze od 160 do 200°C przez co najmniej 4 godziny w atmosferze gazu obojętnego i co najmniej 4 godziny przy obniżonym ciśnieniu. Przedmiotem zgłoszenia jest także środek przeciwstarzeniowy.The subject of the application is a method of obtaining anti-aging agents for elastomers. This method is characterized by a two-stage reaction in which: in the first stage, the pine rosin is heated to a temperature of 170 to 190 ° C and kept at this temperature in an inert gas atmosphere for at least 4 hours, and then the anhydride is added. maleic anhydride and the addition reaction of maleic anhydride to resin acids, addition of maleic anhydride to pine rosin. The reaction is carried out at 160 to 200 ° C under an inert gas atmosphere for at least 6 hours and the reaction mixture is then cooled to 120 to 140 ° C. In the second step, the obtained adducts are reacted with a compound containing at least one primary amine group such as: aniline or 4,4'-diaminodiphenylmethane or triethylenetetramine or an amino derivative of dimerized fatty acids. The reaction is carried out at a temperature of 160 to 200 ° C for at least 4 hours under an inert gas atmosphere and for at least 4 hours under reduced pressure. The subject of the application is also an anti-aging agent.
