Reactive Yellow 4

Dark yellow powder. Solubility in water (50℃) is 40g/L. The aqueous solution is yellow, add 1mol/L sodium hydroxide to turn orange, then add insurance powder and warm to colorless, then add sodium perborate to return to the original color. Deep red in concentrated sulfuric acid, brown-yellow precipitate after dilution; purplish red in concentrated nitric acid, brown-yellow precipitate after dilution. Resistant to alkaline hydrolysis, not resistant to acid hydrolysis. Reactive Yellow 4, also called Reactive Yellow X-RG, is a homotriazine reactive dye. It can fix color at low temperature and is suitable for cold dyes. High reactivity, can be in 20 ~ 40 ℃ alkaline medium solid color fiber, alkaline hydrolysis resistance, not acid hydrolysis resistance. Mainly used for cotton, silk, nylon fiber and viscose, wool fiber dyeing and can be bleached. It can be coated and dyed with ice dye printing.

Using amino C acid, m-toluidine, and cyanuric chloride as raw materials, first diazotize the amino C acid, then couple with m-toluidine, and then condense the coupled product with cyanuric chloride, then salt out, filter and dry Get the finished product.

Reactive Yellow XR is one of the commonly used dyes. It is mainly used for dyeing skeins, fabrics and blended fabrics of cotton or viscose fibers, and is generally not suitable for printing. The color light is red and yellow when used alone, and all the fastnesses are excellent, especially resistant to chlorine bleach. The fastness is a better variety among reactive dyes. It can be used to dye various light colors with Reactive Brilliant Red X-3B, Reactive Brilliant Blue X-BR and Reactive Brilliant Orange X-GN. When used for dyeing blended fabrics, polyester, acrylic, and acetate fibers are not stained, wool is slightly stained, and nylon and vinylon are stained. It can be used for the dyeing of nylon, silk and wool, as well as the direct printing of silk.
