Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania zmodyfikowanego plastyfikatora naftowego TDAE przeznaczonego do kauczuku i gumy, szczególnie do opon samochodowych i zmodyfikowany plastyfikator naftowy TDAE przeznaczony do kauczuku i gumy, szczególnie do opon samochodowych. Przedmiotowy sposób charakteryzuje się tym, że surowiec, którym jest plastyfikator TDAE o dodatniej temperaturze płynięcia, poddaje się procesowi odparafinowania rozpuszczalnikowego obejmującego etap krystalizacji i etap filtracji, przy czym w etapie krystalizacji surowiec poddaje się pierwszemu rozcieńczeniu rozpuszczalnikiem zawierającym 40% - 60% (m/m) dichloroetanu i odpowiednio 60% - 40% (m/m) chlorku metylenu, uzyskując mieszaninę surowca i rozpuszczalnika, którą następnie oziębia się z kontrolowaną prędkością, z równoczesnym doprowadzeniem oziębionego rozpuszczalnika w 1-4 porcjach, przy szybkości schładzania w zakresie 0,15 - 9,0°C/min., aż do osiągnięcia temperatury od -16 do -28°C, przy czym stosunek sumarycznej ilości rozpuszczalnika do surowca zawiera się w przedziale od 2:1 do 11,7:1 (m/m), a wielkość rozcieńczeń wyrażona stosunkiem masowym rozpuszczalnika do surowca wynosi od 0,8:1 do 4,8:1 (m/m), po czym w zakresie temperatur od -15 do -28°C, odfiltrowuje się wydzielone węglowodory, które przemywa się zimnym rozpuszczalnikiem o takim samym składzie jak rozpuszczalnik używany w etapie krystalizacji, stosowanym w ilości od 0,8:1 do 6:1 (m/m), a następnie z filtratu oddestylowuje się rozpuszczalnik uzyskując produkt końcowy o ujemnej temperaturze płynięcia. Zmodyfikowany plastyfikator naftowy TDAE, wytworzony powyższym sposobem, charakteryzuje się tym, że ma ujemną temperaturę płynięcia, korzystnie w zakresie od -13 do -16°C.The subject of the application is a method of producing modified TDAE petroleum plasticizer for rubber and rubber, especially for car tires and modified TDAE petroleum plasticizer for rubber and rubber, especially for car tires. The subject method is characterized in that the raw material, which is a TDAE plasticizer with a positive pour point, is subjected to a solvent dewaxing process including a crystallization step and a filtration step, while in the crystallization step the raw material is first diluted with a solvent containing 40% - 60% (m / m) dichloroethane and respectively 60% - 40% (m / m) of methylene chloride, obtaining a mixture of raw material and solvent, which is then cooled at a controlled speed, with the supply of a cooled solvent in 1-4 portions, with a cooling rate in the range of 0, 15 - 9.0 ° C / min, until a temperature of -16 to -28 ° C is reached, with the ratio of total solvent to raw material in the range from 2: 1 to 11.7: 1 (m / m ), and the amount of dilution expressed as the mass ratio of solvent to raw material is from 0.8: 1 to 4.8: 1 (m / m), then in the temperature range from -15 to -28 ° C, the separated hydrocarbons are filtered off, which is washed with a cold solvent of the same composition as the solvent used in the crystallization step, used in an amount of 0.8: 1 to 6: 1 (m / m), and then from the filtrate the solvent is distilled off to give a final product with a negative pour point. The modified TDAE petroleum plasticizer, prepared by the above method, is characterized in that it has a negative pour point, preferably in the range from -13 to -16 ° C.
