Description
Znany jest sposób wytwarzania barwników siarkowych przez traktowanie aromatycznych weglowodorów zawierajacych conajmniej 3 skondensowane pierscienie oraz ich sulfo,- oksy- albo amino- pochodnych, za pomoca siarki lub srodków wydzielajacych siarke w podwyzszonej temperaturze.Otrzymane w ten sposób przez siarkowanie z pyrenu i jego sulfo,- oksy- albo amino- pochodnych barwniki rozpuszczaja sie w wod¬ nym roztworze siarczku sodu tylko czesciowo, lub daja wyfarbowania w odcieniach czarno- oliwkowych, które nie sa ciekawe dla celów farbiarskich.*) Wlasciciel patentu oswiadczyl, ze wspól¬ twórcami wynalazku sa dr Herbert Bach i Freimut Schmidt Obecnie stwierdzono, iz metylopyreny moz¬ na przeprowadzac w wartosciowe barwniki rozpuszczalne w siarczku sodu przez trakto¬ wanie ich w podwyzszonej temperaturze siar¬ ka albo srodkami oddajacymi siarke.Przyklad I. 20 czesci wagowych 4-metylo- pyrenu ogrzewa sie z 60 czesciami wagowy¬ mi siarki do 240—260°C az do ukonczenia pro¬ cesu siarkowania. Roztopiona surowa mase roztwarza sie z siarczkiem sodu, przy czym praktycznie cala masa przechodzi do roztwo¬ ru. Otrzymany przez znana przeróbke barw¬ nik barwi bawelne z roztworu siarczku sodu w trwalych kolorach o odcieniach czerwona- wo-brazowych.Przyklad II. 20 czesci wagowych 3-mety- lopyrenu ogrzewa sie z 60 czesciami siarki do 240—260°C az do ukonczenia procesu siar¬ kowania; Dalsza przeróbka odbywa sie Jakw przykladzie I. Wydzielony barwnik barwi znanym sposobem w podwyzszonej tempera- baweine z roztworu siarczku sodu w trwalych turze siarka albo srodkami oddajacymi siarke, brazowych odcieniach.VEB Farbenfabrik Wolfen PLThere is a known method of producing sulfur dyes by treating aromatic hydrocarbons containing at least 3 condensed rings and their sulfo, - oxy- or amino derivatives, with sulfur or agents that release sulfur at elevated temperature. Thus obtained by sulfurization of pyrene and its sulfo, - oxy- or amino-derivative dyes dissolve only partially in an aqueous solution of sodium sulphide, or they give black-olive dyes that are not interesting for dyeing purposes. *) The patent owner stated that the inventors are Dr. Herbert Bach and Freimut Schmidt It has now been found that methylpyrenes can be converted into valuable sodium sulfide-soluble dyes by treating them at elevated temperature with sulfur or with sulfur donating agents. Example 1 20 parts by weight of 4-methylpyrene is heated. with 60 parts by weight of sulfur up to 240-260 ° C until the sulfurization process is complete. The molten crude mass is dissolved with sodium sulphide, with virtually all of the mass passing into the solution. The dye obtained by known processing dyes cotton from sodium sulphide solution in persistent colors with shades of red-brown. Example II. 20 parts by weight of 3-methylopyrene are heated with 60 parts of sulfur to 240-260 ° C. until the sulfurization process is complete; Further processing is carried out as in example I. The separated dye is dyed in a known way at an elevated temperature from a solution of sodium sulphide in a stable turn of sulfur or with agents that give off sulfur, brown shades.
