Description
изобретение отлоситс к снособам .получе ,11и дубител дл кожи. Известен способ получени дубител с «рас н1И:М11 овойства мн окислением резорцинфорМ альдегидной смолы, .например перекисью водорода . Полученный дубитель окраншвает хожу в красный цвет. Цель изобретений - иолучсние дуйптел , .способного окрашивать кожу в ч&рный цвет. Это достигаетс тем, что перед окисле:Н::1ем смолу обрабатывают азотно кислотой и окисление .ведут в среде аммиака. П р и м е р. Резорщшоф:0рмальдетидную смолу, полученную путем конденсации в кислой среде ре .зорци.на с фо:рмалвдепидом в мол ;р1НОМ отноапешпи 2:1, обрабатывают азотной кислотой П;ри О-5°С 2,5-5,0 час. Продукт иитюова и иейт раЛизуют водным а.ммтгаком и затем окнел ют , Н1ап;ример Перекнсью :водорода, в течение 30-60 мин при 50-60°С. Соотношение реагентов, в вес. ч.: РФС100 Азотна кислота175-350 А,-мм1иак ВОД.ИЫЙ40-80 Пе-рекись водорода50-75 Полученный дубитель по своим дуб щим войствам не уступает РФС (см. таблицу) п ри.тает коже л кожевой ткани меха цвет от фиолетового до черного в зависимости от кол ичества даваемого окисллтел . т а б /1 и и а Показатели дубител Пред М е т ,и з о б р е т е и н Способ иолучести дубител с крас гцим свойствами окислеплем |резорцииформ альдегидной , отличающийс тем, что, с целью получени ду.бчгтел , окрашивающего кожу в чериый цвет, пе1ред оюисле.нлем с.молу обрабатывают азотной мислотой и окислеиие ведут в среде аммиака.the invention relates to methods of receiving, tanning and tanning. A known method for the preparation of a tanning agent from the "MAS: M11" manufacture is accomplished by oxidation of resorcinolM aldehyde resin, for example, hydrogen peroxide. The resulting tanning agent paints go to red. The purpose of the inventions is to give a double duiptel capable of dyeing the skin in h & r color. This is achieved by the fact that before the oxide: H :: 1 the resin is treated with nitric acid and oxidation will be carried out in an ammonia medium. PRI me R. Resorption: 0 ml of the resin obtained by condensation in an acidic environment of res.zorts.na with fo: rmalvdepi in mol; p1NOM otnapeshpi 2: 1, treated with nitric acid P; Ri-5 ° C for 2.5-5.0 hours. The product is manufactured by Iyutova and Iyt is lysed with aqueous ammonia and then glazed, for example, by hydrogen: for 30-60 minutes at 50-60 ° C. The ratio of reagents, in weight. h .: RFS100 Nitric Acid175-350 A, -m1liaq WATER.IIHI40-80 Hydrogen recess 50-75 The obtained tanning agent does not yield to RFU (see table). to black, depending on the amount of oxidyl given. t a b / 1 and a a. Indicators of a dubitel of Pre Met and of a boutte and n. The method of imitation of a dubitel with red oxidizing properties of aldehyde, characterized in that, in order to obtain a double color dye. the skin is black in color, before it is treated with a nitrogen mislot, and oxidation is carried out in an ammonia medium.
