Property of Basic Rhodamine B:Bright green shining fine powder.Soluble in water and alcohol (blue red solution with strong fluorescence), easily soluble in fiber, slightly soluble in acetone. In the presence of concentrated sulfuric acid, it is yellowish brown with strong green fluorescence.It is bright red and orange after dilution. It is golden yellow in the presence of concentrated nitric acid.The aqueous solution was heated with sodium hydroxide solution to form rose red villous precipitation. The addition of hydrochloric acid has a fine green crystal separation.
Application : mainly used for dyeing of paper and cosmetics,also can be used in dyeing silk, wool, bamboo, weed, straw, leather, linen and preparation of lakes.It is used for dyeing acrylic fiber with stable shade when pH is 2.5 ~ 5.5.
Basic Rhodamine B will not appear sublimation state in high temperature environment. The dyeing of Basic Rhodamine B has certain firmness. Compared with other dyes, it can directly contact human skin and will not cause harm to human body.The dyeing effect of Basic Rhodamine B is relatively firm.With correct operating procedures in the process of use, it will reduce the probability of fading.Most of the dyes will change in the high temperature environment, leading to the discoloration of the dyed products, which not only affects the appearance, but also affects the normal use. On the contrary, the molecular size and polarity of Basic Rhodamine B are large, which will not fade in the high temperature environment. We should also pay attention to avoid long-term exposure to the sun in our daily life.
