This product is toxic. In acute poisoning, coma and cyanosis may occur, and in severe cases, shock may be life-threatening. Cats will die within 3 days after applying this ointment on their skin. The maximum allowable concentration in the air in the production workshop is 0.05 mg/m3. The production workshop should be well ventilated and the equipment should be sealed. Operators should wear protective equipment, avoid direct contact, and avoid inhalation and swallowing.
　

Storage method

Seal and save.

Packed in iron drums lined with plastic bags, 20kg or 40kg per drum. Store in a dry, ventilated place to prevent heat and moisture. Store and transport according to regulations on toxic chemicals.

Synthesis method

Meta-nitrochlorobenzene is reduced with iron powder to obtain m-chloroaniline.After distillation, it is salted out with hydrochloric acid, filtered, and dried to obtain the finished product. The diazo value of dry industrial products is ≥95%. Raw material consumption quota: m-chloroaniline (98%) 840kg/t, hydrochloric acid (31%) 882kg/t.

Purpose

Ice dye base is mainly used as a color developer for dyeing and printing cotton, linen, and viscose fabrics. It is also used as an intermediate for medicines and pesticides.
