Nature and stability

edit

1. Toxicology is similar to phenol, and it Is a stronger corrosive. Strongly irritating to the skin. It is easily absorbed through the skin. Toxic to blood circulation and kidneys. In addition, it can Cause corneal damage. Although the lethal amount is unknown, there have been Cases of death from topical application of 3 to 4g. Production equipment should Be sealed and leak-proof, and should be washed off in a timely manner if Splashed on the skin. Workshops should be ventilated and equipment should be Airtight. Operators should wear protective gear.

2. Flammable, the color of long storage Gradually become darker, stable in the air, but when exposed to the sun Gradually become darker. Sublimation by heating, with irritating phenol odor.

3. Present in the flue gas. 4.

4. Aqueous solution turns green with ferric Chloride [1].

 

Storage method

edit

1. Lined with plastic bags, sacks or woven Bags, net weight 50kg or 60kg per bag.

2. Storage and transportation should be Fireproof, moisture-proof, anti-exposure. Stored in a dry, ventilated place. Store and transport according to the regulations of flammable and toxic Materials.
