Wiadomo, ze przy reakcji miedzy wol- framianaimi, molibdeinianami i fosforanami tworza sie dwa razne kwasy zespolone o wzorach: 24 (W03 + MoOJ P2053H3 i 18 (W03 + Mo03) P2053H20.Oba te zwiazki mozna rozdzielic, przez wykrystalizowanie pierwszego z nich w po¬ staci soli sodowej i przez wysolenie dru¬ giego z pozostalego lugu macierzystego.Obecnie wykryto, ze oba te zwiazki moz¬ na zapomoca srodka redukujacego zredu¬ kowac do bardzo ciemnego zabarwienia niebieskiego, poczem np. osadlzic zapomoca kwaistu solnego w postaci czarnych kryszta¬ lów, wskutek czego otrzymuje sie inne zwiazki kwasu fojsiorowolframomolibdeno- wego. Otrzymane w sposób powyzszy kry¬ sztaly rozpuszczaja sie latwo w wodzie i wykazuja ponadto charakterystyczne róz¬ nice obu substancyj niezredukowanych.Produkt dedukcji kwasu: 3H2O.P203 24 {W03 + Mo03) jak i sam kwas w stanie niezredukowanym daja niierozpuszcizaJlna w wodzie sól amo¬ nowal, podczas gdy produkt redukcji kwasu: 3H2O.P203 18fW03 + Mo03) jak równiez i kjwas niczredukowany daja sól amonowa, rozpuszczalna w Wodzie. Produkty reduk¬ cji sa calkowicie odporne na dzialanie po¬ wietrza i w roztworze wodnym dajja sie przeprowadzic zpowrotem w pierwotna, niiiezrediukowana sól dopiero zapomoca srodków utleniajacych (np. nadjmarigainiia-nem, dwutlenkiem wodoru i podobneimi u- tleniajacemi substancjami),. Do teredufcowa- pia ihipiipa sip/pw&cTfcnane srodki reduku¬ jace* jak to: kwas siarkowy, dwusiarczyn, hydirosiarczyn, nizsze stopnie utlenienia molibdenu, cukier gronowy i inne zwiazki; Przyklad 100 cz. wag. soli sodowej kwasu zespolonego. 3H2O.P203 24 (W03 + MoOJ rozpuszcza sie w 300 cz. wag, wody i po ochlodzeniu zadaje sn'e 20 cz, wag. roztwo¬ ru Idwuisiiarczynu sodowego o 38° Be, po¬ czern ogrzewa sale sitopniowo do wrzenia i ptfzez pewien czas gotuje.

I tak np. zapomoca osadzenia rodlaminy B (Schultz, Farb- stofftabellen 6. Auflage 1923, Nr. 573) za- pomoca opisanego w przykladzie produktu stofftabellen 6.

PL PLIt is known that during the reaction between tungsten, molybdeates and phosphates, two complex acids are formed with the following formulas: 24 (W03 + MoOJ P2053H3 and 18 (W03 + Mo03) P2053H20. Both these compounds can be separated by crystallizing the first of them into In the form of the sodium salt and by salting out the second from the remaining mother liquor. It has now been found that both of these compounds can be reduced to a very dark blue color with a reducing agent, and then, for example, to settle with the salt acid in the form of black crystals. as a result of which other compounds of phosphotungsticomolybdic acid are obtained. The crystals obtained in this way dissolve easily in water and show the characteristic differences of both non-reduced substances. Acid deduction product: 3H2O.P203 24 {W03 + Mo03) and the acid itself in the unreduced state gives a non-soluble water-soluble salt, while the product of the reduction of the acid: 3H2O.P2O3 18fW03 + Mo03) as well as an acid The non-reduced result is an ammonium salt, soluble in Water. The reduction products are completely resistant to the action of air and can be converted back into the original, undreduced salt in an aqueous solution only with the aid of oxidizing agents (for example, hypermarigain, hydrogen dioxide and similar oxidizing substances). For teredufcation ihipiipa sip / pw & cTfcnane reducing agents * such as: sulfuric acid, bisulfite, hydrosulfite, lower molybdenum oxidation, grape sugar and other compounds; Example 100 parts wt. the sodium salt of a complex acid. 3H2O.P2O3 24 (WO3 + MOO is dissolved in 300 parts by weight of water and, after cooling, 20 parts by weight of sodium hydrogen chloride solution are added by 38 ° B, the mixture is heated up to the boil in the sieve chamber and time it cooks. After cooling, the cMcHO-hydro gas is puffed up, which causes the above-described compound to settle in the form of beautiful black crystals. The crystals dissolve easily in the water, leaving it with a blotchy * purple colony. New products for reduction are perfect for reduction. obtaining light-resistant varnishes from basic or acid dyes, containing, next to the sulfonyl group, in qlma or a substituted amino group, for example by depositing rhodamine B (Schultz, Farbstofftabellen 6. Auflage 1923, No. 573 ) with the product stofftabellen 6 described in the example. Auflage 1923, No. 573) light-fastener. PL PL
