Description
Wynalazek dotyczy sposobu otrzy¬ mywania oleju przetwornikowego z ole¬ jów dziegciowych.Okazalo sie, ze przy traktowaniu olejów dziegciowych srodkami utleniajacemi, jak dwuchromian potasu, mieszanina nadman- ganjanowai pod. przy niskich temperatu¬ rach, nastepuje taka zmiana tych olejów, ze rozdzielaja sie one na ciagnace sie zywice i plynne oleje, które moga byc zastoso¬ wane jako oleje przetwornikowe.Te oleje dziegciowe mozna traktowac srodkami utleniajacemi bezposrednio, albo tez po rozpuszczeniu w srodku rozpusz¬ czajacym, na który nie dziala srodek utleniajacy.Ten sposób wykonania przedstawia te korzysc, ze mozna pracowac przy wyzszych temperaturach.Przyklad. 100 kg oleju dziegciowego oziebia sie do 15° — 20°C i poddaje w ciagu mn. w. 1 godziny, mieszajac, dzialaniu mieszaniny chromowej. Nastepnie po¬ zwala sie mieszaninie przybrac tempera¬ ture pokojowa. Podczas stania wydziela sie z mieszaniny ciagnaca sie zywica.Ole] stojacy ponad nia^ oddziela sie i pod¬ daje rafinacji z 2 — 3°/0 66° Be kwasu siarkowego. Po odciagnieciu kwasu siar¬ kowego i wymyciu destyluje sie olej • w prózni.Przyklad. 100 kg oleju dziegciowego roz¬ puszcza sie w 100 kg benzyny i utlenia nastepnie przy 0 — 5°. Dalej postepuje sie po odpedzeniu rozpuszczalnika, do¬ kladnie jak w przykladzie 1. PL PLThe invention relates to a method of obtaining transducer oil from tar oils. It has been found that when treating tar oils with oxidizing agents, such as potassium dichromate, a mixture of permanative substances is present. at low temperatures, these oils change so that they separate into stringy resins and liquid oils which can be used as transducer oils. A non-oxidizing agent. This embodiment has the advantage that it is possible to work at higher temperatures. 100 kg of tar oil is cooled to 15 ° - 20 ° C and processed overnight. at. 1 hour, stirring, the action of the chrome mixture. The mixture was then allowed to return to room temperature. On standing, a sluggish resin separates from the mixture. The oil that is above it is separated and refined with 2-3% sulfuric acid. After the sulfuric acid has been stripped off and washed, the oil is distilled under a vacuum. Example. 100 kg of tar oil are dissolved in 100 kg of gasoline and then oxidized at 0-5 °. The next step is after the solvent has been stripped off, exactly as in example 1. PL PL
