1. Properties: black-brown crystals, also flakes.
2. Melting point (℃): 306
3. Boiling point (℃): 319
4. Relative density (water=1): 2.90
5. Relative vapor density (air=1): 5.61
6. Critical pressure (MPa): 4.3
7. Solubility: easily soluble in water, soluble in glycerin, and easily soluble in methanol, ethanol, acetone, and ether.
1. Its aqueous solution is acidic and corrosive. After hydrolysis, brown flocculent iron hydroxide is formed, which has strong cohesion. Easily deliquescence in the air, strong hygroscopicity. Can generate 2, 2.5, 3.5, 6 water. It is a strong oxidant and can undergo redox reaction with copper, zinc and other metals. Form complexes with many solvents. Reacts with potassium ferrocyanide to produce dark blue Prussian blue. Workers should be well protected. If they accidentally touch the skin, they should immediately rinse with running water. This substance should be stored separately from metal powder, flammable and combustible materials, reducing agents, etc. Anhydrous ferric chloride can be dissolved in many solvents, especially those that can form complexes with ferric chloride, such as alcohols, ethers, ketones, pyridine, benzonitrile, phosphorus tribromide, Sulfur dioxide and sulfuryl chloride. When heated in the air, it becomes iron oxide and chlorine.
2. It can be sublimated at a temperature slightly lower than the melting point. From the measurement of the vapor density, it can be known that it is a dimer at 440°C, and a monomer at a temperature higher than 750°C. However, when the temperature is higher than this temperature, a chlorine release reaction will occur. . When in contact with humid air, anhydrous salt is easily converted into yellow-brown hexahydrate. Therefore, if it is necessary to transfer anhydrous ferric chloride from one container to another instrument, it should be carried out in a "dry box". Or follow the method proposed by Bergstrom.
3. Stability: stable
4. Incompatible materials: strong oxidants, potassium, sodium
5. Polymerization hazard: no polymerization
6. Decomposition product: chloride
