properties and stability
this product is highly toxic. its toxicity is similar to that of p-nitroaniline. for its toxicity and protection methods, see p-nitroaniline.
storage method
this product should be sealed and stored in a cool, dry place away from light.
packaged in plywood barrels or cardboard barrels lined with plastic bags, 35kg or 50kg per barrel. store in a cool, ventilated place. avoid exposure to sunlight and rain during storage and transportation. store and transport according to regulations on toxic chemicals.
synthesis method
using 2,5-dichloronitrobenzene and liquid ammonia as raw materials, it is obtained by first pressurizing ammonolysis and crystallization, then filtering and drying. raw material consumption quota: 2,5-dichloronitrobenzene (industrial product) 1167kg/t, liquid ammonia (industrial product) 230kg/t, ammonia water (industrial product) 2420kg/t.
purpose
ice dye base is used to prepare organic pigments and dyes such as bright red lake and bright yellow 10g lake. it is used as a developer for printing and dyeing cotton and viscose fabrics, and can also be used for printing and dyeing silk and polyester fabrics.
