Reactive Yellow FG - Introduction
Reactive light yellow FG is a chemical substance, its chemical name is "reactive dye light yellow FG". The following is a description of its nature, use, preparation and safety information:
Nature:
Reactive light yellow FG is an organic dye with light yellow to yellow crystals, which is easily soluble in water and some organic solvents. It has good thermal stability and light resistance, stable under acidic and neutral conditions, but less stable under alkaline conditions. The substance is a cationic dye, can be with anionic groups (such as cellulose, protein, etc.) adsorption reaction.
Use:
Reactive light yellow FG is mainly used as a dye and colorant, and is widely used in textile, printing, leather, paint, plastic and other industries for dyeing and coloring. Due to its good affinity and adsorption capacity, it can be used in the dyeing and printing process of cellulose materials (such as cotton, hemp, etc.). At the same time, reactive light yellow FG can also be used to prepare other chemicals, such as dye intermediates and pigments.
Preparation Method:
Active light yellow FG is generally prepared by chemical synthesis. The specific preparation method is more complex, usually including the reaction of synthetic raw materials, the adjustment of the dye structure and purification steps. One of the common synthetic methods is to carry out condensation reaction of appropriate aromatic amine compounds and appropriate aromatic aldehyde compounds under acidic conditions, and then carry out subsequent oxidation and purification steps.
Safety Information:
the use of active light yellow FG should pay attention to some safety matters. It is a substance that is irritating to the eyes and skin and should be handled with appropriate protective gloves, goggles and face shields. Avoid inhaling its dust or solution, and keep it well ventilated when using it. If touched or swallowed, wash or seek medical help immediately. In addition, the active light yellow FG should avoid high temperature and direct sunlight during storage and transportation to prevent its degradation and dangerous accidents.
