Description

Znaleziono, ze dwuazowane estry kwasu 4-nitro-2-aminobenzoesowego, w przeciwien¬ stwie do dwuazowanych estrów izomerycz¬ nych kwasów 2-nitro-4-amino-benzoesowego i 3-nitro-5-amino-benzoesowego, daja z [j -naf- tolem,zólte odcienie, o wielkiej trwalosci na dzialanie chloru i na pranie. W ten sposób o- trzymane zabarwienia daja sie wywabiac hy- drosiarczynem i wyrózniaja sie odpornoscia na dzialanie chloranów.Na tkaninie zaprawionej amidami arylowe- tni kwasu p-oksy-naftoesowego otrzymuje sie z dwuazowanemi estrami kwasu 4-nitro-2-a- tnido-benzoesowego zywy szkarlatny kolor, a na zaprawie z metyleno-fenylo-pyrasolonu — jaskrawa zólcien..Przyklad: Tkanine napaja sie nizej podana zaprawa naftolowa, suszy sie, drukuje nizej podana iarba, plócze i pierze w mydle.Zaprawa naftolowa: 25 g J3-naftolu, 40 cm3, lugu sodowego 22° Be, 20 g kwasnego ry- cynjanu amonu.Wszystko dopelnia sie do 1 litra.Farba drukarska. 19,6 g estru metylowego kwasu 4-nitroT2-a- mino-benzoesowego rozrabia sie 30 cm3 kwa¬ su solnego 22° Be. Dodaje sie 150 cm3 wrza¬ cej wody, miesza dobrze i chlodzi, dodajac 250 g lodu.Nastepnie dodaje sie powoli 26 cm3 roztwo¬ ru azotynu (290 g w litrze), miesza sie przez pewien czas, przesacza i dopelnia roztwór do 500 g. Zageszcza sie dodajac 460 g zageszcze¬ nia tragantowego (60 : 1000) i dodaje przed uzyciem 40 g octanu sodowego. PL PLIt has been found that the diazotized esters of 4-nitro-2-aminobenzoic acid, unlike the diazotized isomeric esters of 2-nitro-4-amino-benzoic and 3-nitro-5-amino-benzoic acids, give with naphthol, yellow shades, with great durability to chlorine and washing. The dyes obtained in this way can be treated with hydrosulphite and are distinguished by resistance to the action of chlorates. On fabric treated with aryl amides, p-oxy-naphthoic acid is obtained with diazotized esters of 4-nitro-2-a-tinido acid. Vivid scarlet color of benzoic acid, and bright yellow on the methylene-phenyl-pyrasolone mortar. Example: The fabric is watered with the naphthol mortar given below, dried, and the ink, fluff and washed in the soap are printed. Naphthol paste: 25 g J3- naphthol, 40 cm3, sodium liquor 22 ° Be, 20 g of acid ammonium ritinate. Everything is filled to 1 liter. Printing ink. 19.6 g of 4-nitroT2-α-amino-benzoic acid methyl ester are worked up with 30 ml of hydrochloric acid 22 ° Be. 150 cm 3 of boiling water is added, mixed well and cooled with 250 g of ice. Then 26 cm 3 of nitrite solution (290 g per liter) is added slowly, stirred for some time, filtered and made up to 500 g. 460 g of a traganthus (60: 1000) are added and 40 g of sodium acetate are added before use.
