Description
Wykryto, ze barwniki fioletowe mozna otrzymac sprzegajac dwuazozwiazki ete¬ rów anidonaftolowych z arylamidami kwa¬ su 2.3-oksynaftoesowego, przyczem ciala te mozna sprzegac jako substancje lub tez na wlóknie. Wynik ten jest godny uwagi, gdyz dotychczas fioletowe produkty w sze¬ regu podobnych barwników byly nieznane.Przyklad. 2,5 czesci wagowych 7-met- oksy-f-amidonaftalenu o punkcie topliwo¬ sci 81° w postaci soli kwasu solnego, roz¬ puszcza sie w wodzie i po dodaniu 4 cze¬ sci wagowych ikwasu solnego dwuazuje w sposób zwykly, W celu podniesienia trwa¬ losci zwiazków dwuazowych mozna dodac kwasów iiaftalenoisulfonowych. Nastepnie mieszanine reakcyjna dopelnia sie woda do 1000 cz. obj. nadmiar kwasu mineral¬ nego zobojetnia octanem sodowym i przez te kapiel przeciaga towar po uprzedniem zaprawieniu go roztworem, zawierajacym w litrze 2,5 g p -naftylamidu kwasu 2-3- oksynaftoesowego. Po wyplókaniu towar mydli sie, gotujac. Otrzymuje sie jasny fio¬ let o odcieniu czerwonawym, odporny na dzialanie chloru, swiatla i wrzatku. PLIt has been found that violet dyes can be obtained by bonding diazotones of anidonaphthol ethers with 2,3-oxynaphthoic acid arylamides, and these bodies may be bonded as substances or on fibers. This result is remarkable as violet products in a number of similar dyes were previously unknown. 2.5 parts by weight of 7-methoxy-f-amidonaphthalene having a melting point of 81 ° as hydrochloric acid salt, are dissolved in water and, after adding 4 parts by weight and hydrochloric acid, diazotize in the usual manner. To increase the stability of the diazo compounds, iaphthalenesulfonic acids can be added. Then the reaction mixture is made up to 1000 parts with water. vol. the excess of mineral acid is neutralized with sodium acetate and the goods are drawn through this bath after being treated with a solution containing 2.5 g of p-naphthyllamide of 2-3-oxynaphthoic acid per liter. After washing, the goods are soaked while boiling. A bright violet with a reddish hue is obtained, resistant to the action of chlorine, light and boiling water. PL
