Przy obróbce metali kwasami, zwla¬ szcza przy zaprawianiu metali, jak równiez i przy przeróbce kwasnych roztworów w aparatach metalowych, zachodzi niepoza¬ dane nagryzanie metali przez kwas.Wykryto, ze niepozadane dzialanie kwa¬ su na metal mozna znacznie zmniejszyc, je¬ zeli do kwasu dodac pewna ilosc organicz¬ nego sulfotlenku. Jako szczególnie nadajace sie do tego celu okazaly sie np. sulfotlenek benzylowy CGH5CH2—SO—C6ff5Cff2, sul¬ fotlenek dwufenylowy C6#5—SO—C6//5, sulfotlenek dwualkylenowy, np. C2H5— —SO—C2/f5. W licznych przypadkach, zwlaszcza gdy uzyty sulfotlenek jest roz¬ puszczalny w kwasie w niedostatecznym stopniu, dobrze jest dodac srodków zwil¬ zajacych, emulgujacych lub pieniacych sie.Jako takie moga znalezc zastosowanie np. kwasy alkylonaftalenosulfonowe i ich sole lub saponiny.Ponizej podaje sie wyniki przeprdwa^ dzonych prób z zaprawami wedlug wyna¬ lazku.Przy próbach tych stosowano kawalki zelaza tasmowego o wymiarach okolo 8,0 x x 1,6 x 0,075 cm i wadze okolo 5 g, srodek ochronny stosowano w ilosci 0,1 g.Rodzaj srodka ochronnego Sulfotlenek benzylowy .C6//5Cff2 — S — CH2C$Hh u 0 Sulfotlenek dwufenylowy .C^Hs — S —Cjn5 H 0 Sulfotlenek dwufenylenowy Polimeryczny sulfotlenek dwuetylowy . . . .Dwusulfotlenek tiantreno- /\/so\ \/ Rodzaj kwasu w w »» n t» Stezenie 20% n M 11 w n n n Ilosc cm3 100 »» 11 tl Czas trwania reakcji (w godzi¬ nach) 2 i» * »» »» H V f» Tempera¬ tura pod¬ czas reakcji 60° 80° 90° 60° 90° 60° 60° 90° 60° Strata na wadze w U = % 0,02 =0,4% 0,025=0,5% 0,03 =0,6% 0,02 =0,4% 0,3 =0,6% 0,02 =0,4% 0,01 =0,2% 0,015=0,3% 0,04 =0,8% Bez dodatku srodka ochronnego w temperaturze 80°C rozpuszcza sie w ciagu godziny okolo 57% zelaza. PLIn the treatment of metals with acids, especially in the treatment of metals, as well as in the treatment of acid solutions in metal apparatus, undesirable acid burns to the metal occurs. It has been found that the adverse effect of acid on the metal can be significantly reduced if add some organic sulfoxide. For example, benzyl sulfoxide CGH5CH2 — SO — C6ff5Cff2, diphenyl sulfoxide C6 # 5 — SO — C6.5, dialkylene sulfoxide, for example C2H5 — —SO — C2 / f5, have proved to be particularly suitable. In many cases, especially when the sulfoxide used is insufficiently soluble in acid, it is advisable to add wetting, emulsifying or foaming agents. For example, alkylnaphthalenesulfonic acids and their salts or saponins can be used. In these tests, pieces of strip iron with dimensions of about 8.0 x 1.6 x 0.075 cm and a weight of about 5 g were used, the protective agent was used in an amount of 0.1 g. Benzyl sulfoxide.
