Description
Wyfarbowanie prowadzi sie w temperaturze 60°C przez 30 minut. Po tym czasie dodaje sie roztwór (0,3 g hydrosulfitu w 5 ml wody destylowanej), temperature kapieli podnosi sie do 80°C i ogrzewa sie zanurzone motki mieszajac co jakis czas przez dalsze 30 minut. Nastepnie motki po wypraniu suszy sie na powietrzu. Motki sa wybarwione na kolor ciemnozielony. Celem uzyskania czerni nalezy poddac wybarwione motki kapieli utleniaja¬ cej (np. w roztworze podchlorynu).Przyklad II. W kolbie okraglodennej o pojemnosci 250 ml zaopatrzonej w chlodnice powietrzna umieszcza sie 9 g dwubromowiolantronu o zawartosci czystego dwubromowiolantronu 95%. Nastepnie dodaje sie 9 g mocznika i 4,5 g octanu sodowego oraz 0,01 g sproszkowanej miedzi metalicznej. Calosc ogrzewa sie na lazni olejowej w temperaturze 145-155°C przez 2 godziny. Podczas reakcji nastepuje lekkie spienienie njasy reakcyj¬ nej. Po uplywie 2 godzin do goracej mieszaniny reakcyjnej dolewa sie 60 ml wody destylowanej i calosc poddaje sie saczeniu, przemywa sie porcjami 4 razy po 30 ml goracej wody. Uzyskana wydajnosc produktu wynosi 6,7 g tj. 93,9% w stosunku do uzytego dwubromowiolantronu i 98,5% w stosunku do zawartosci dwubromowiolan¬ tronu.Otrzymany barwnik o wzorze sumarycznym C34 H16 N2 02 jest czarnym proszkiem o temperaturze rozkladu ponad 465°C.Otrzymane wybarwienie koloru ciemnozielonego na motkach bawelnianych potwierdza bardzo wysoki stopien czystosci otrzymanego produktu. PL PLThe dyeing is carried out at 60 ° C for 30 minutes. After this time, a solution (0.3 g of hydrosulfite in 5 ml of distilled water) is added, the bath temperature is raised to 80 ° C and the submerged skeins are heated with agitation at intervals for a further 30 minutes. The skeins are then dried in the air after washing. Skeins are colored dark green. To obtain blackness, the dyed skeins should be treated with an oxidizing bath (eg in a hypochlorite solution). Example II. In a 250 ml round bottom flask equipped with air coolers are placed 9 g of dibromoviolanthrone containing 95% pure dibromoviolanthrone. Then 9 g of urea and 4.5 g of sodium acetate and 0.01 g of powdered metallic copper are added. Everything is heated in an oil bath at 145-155 ° C for 2 hours. During the reaction, slight foaming of the reaction mixture occurs. After 2 hours, 60 ml of distilled water is poured into the hot reaction mixture and the whole is filtered, washed 4 times with 30 ml of hot water. The obtained product yield is 6.7 g, i.e. 93.9% in relation to the used dibromovolanthrone and 98.5% in relation to the content of dibromovolanthrone. The obtained dye with the formula C34 H16 N2 02 is a black powder with a decomposition temperature over 465 ° C. C. The obtained dark green color on the cotton skeins confirms a very high degree of purity of the obtained product. PL PL
