Description
Najdluzszy czas trwania patentu do dn. 4 marca 1940 r.Sposób otrzymywania barwników o-o- ksyjednoazowych podlug patentu Nr 1700 polega na tern, ze dwuazonowany kwas pikraminowy laczymy z 4-acetylamino- 1-oksy-benzolem lub jego podstawionemi.Ponadto wykryto, ze mozna otrzymac barwniki tej samej wartosci, jezeli w me¬ todzie wedlug patentu Nr 1700 zastapic 4-acety lamino-1 -oksy-benzol pochodnemi 2- lub 3-aeetylamino-l-oksy-benzolu. Bar¬ wa osiagnieta zapomoca nowego barwnika na zaprawie chromowej wykazuje odpor¬ nosc równie wielka, jak i zapomoca barwni¬ ków, otrzymanych sposobem zasadniczym, lecz posiada odcien bardziej zólty niz tamte.Przyklad. 19,9 czesci kwasu pikramino- wego poddane zostaja dwuazonowaniu, jak zwykle, i polaczone z roztworem alkalicz¬ nym 18,5 czesci l-metylo-3-acetylamino- 4-oksy-benzolu. Powstaly barwnik zostaje wysolony i wysuszony. Barwi welne na za¬ prawie chromowej na kolor oliwkowobru- natny zapomoca sposobu jednokadziowego. PLThe longest term of the patent until March 4, 1940 The method of obtaining ooxonease dyes under the patent No. 1700 consists in combining diazotized picramic acid with 4-acetylamino-1-oxy-benzole or its substituted. Moreover, it was found that dyes of the same value could be obtained, if replace 4-acetylamino-1-oxy-benzole with a derivative of 2- or 3-acetylamino-1-oxy-benzole in the method according to patent No. 1700. The color achieved with the use of a new dye on a chrome mortar shows resistance as much as that of dyes obtained by the basic method, but has a shade more yellow than the others. 19.9 parts of picramic acid are diazonized as usual and combined with an alkaline solution of 18.5 parts 1-methyl-3-acetylamino-4-oxybenzole. The resulting dye is salted out and dried. It dyes the wool almost chrome in an olive-brown color using the one-pot method. PL
