ferro66 - Nature
Open Data Verified Data
white or light green cubic crystals or scale crystals. Easy to absorb moisture, exposure to air is easy to be oxidized to generate ferric chloride and gradient to yellow or red brown. The relative density was 3. 162. Melting point 677 °c. Boiling point 1023 °c. The heat of fusion was 43. Olkj/mol and was sublimed at about 700 °c in a stream of hydrogen chloride. Soluble in water, methanol, ethanol, acetone and benzene-soluble, insoluble in ether, its aqueous solution can occur mild hydrolysis. Ferric chloride and alkali metal chloride, ammonia, etc. can form complexes, the hydrate has 1, 2, 4, 6 water, the hydrate decomposes to iron oxide and hydrogen chloride when heated to 250 °c in air.

ferro66 - Preparation Method
Open Data Verified Data
- chlorination method: the metallic iron is heated, and chlorine gas is introduced to generate anhydrous ferrous chloride.
- reduction method: anhydrous ferric chloride is introduced into dry hydrogen and heated to obtain anhydrous ferrous chloride. The generated hydrogen chloride gas can be absorbed with water to form dilute hydrochloric acid.

Store in a cool, ventilated, dry warehouse. They shall not be co-stored and co-transported with toxic substances. In the transport process to prevent rain and sun exposure. Handling should be light and light unloading, to prevent packaging damage. Fire, water, sand and all kinds of fire extinguishing. Toxicity and protection: This product is harmful to food, can stimulate the eyes, and can seriously harm the eyes. Harmful steam can be generated when exposed to fire. If contact with the skin, the application of a large number of water rinse, such as accidentally into the eyes, should immediately lift the eye shade, with a large number of running water or saline thoroughly rinse, and timely medical treatment. When eating, drink plenty of warm water to induce vomiting. The patient visited hospital. In the process of production and use, operators should wear dust filters, protective glasses, tape anti-virus clothing and gloves, etc., the equipment should be closed operation, local ventilation, to avoid the generation and inhalation of dust. Smoking, drinking and eating are prohibited at work. After completion of work, shower and dressing.

| Introduction | ferrous chloride is a white rhomboid crystal having a CdCl2-type structure. The melting point is 672 ℃, the boiling point is 1030 ℃, and the relative density is 3.16225. White crystals sublimed in a hydrogen chloride gas stream at 700 ° C. Are highly hygroscopic. The dihydrate is a slightly light green colorless monoclinic crystal with a relative density of 2.358, which is easy to oxidize in air, decomposes to form monohydrate at 150~160 ℃, and loses all crystal water at 220 ℃. The tetrahydrate is a blue-green monoclinic crystal with hygroscopicity and a relative density of 1.93. Very soluble in water and ethanol, soluble in acetone, slightly soluble in benzene, insoluble in ether. It is highly susceptible to oxidation in moist air. |
| Application | ferrous chloride can be widely used as reducing agent, mordant in dyeing, pharmaceutical preparation and metallurgical industry. |
| preparation method | the temperature of iron in the dry hydrogen chloride gas stream is controlled to be below 500 °c, or in 300~350 deg C with dry hydrogen reduction of anhydrous ferric chloride obtained. |
| solubility in water (g/100ml) | grams dissolved per 100ml of water at different temperatures (℃): 49.7g/0 ℃;59g/10 ℃;62.5g/20 ℃;66.7g/30 ℃;70g/40 ℃; 78.3g/60 ℃;88.7g/80 ℃;92.3g/90 ℃;94.9g/100 ℃ |
| purpose | is used in metallurgy and pharmaceutical manufacturing. Used as mordant and reducing agent. used as analytical reagent, mordant, also used in Metallurgical Industry used as water treatment purification agent, reducing agent, unleaded gasoline additive, etc. |
| production method | in a hard glass tube, anhydrous ferric chloride is quickly placed, and one end of the tube is passed through the dried hydrogen gas, after sufficient replacement and removal of the air in the tube, the reaction tube is heated, and a large amount of hydrogen chloride is discharged at the other end of the tube, which can be absorbed into dilute hydrochloric acid with water. When the rate of release of hydrogen chloride slows down and the ferric chloride turns into white crystals, the reaction is complete, the heating is stopped, and the product in the tube is brought to room temperature in a weak flow of hydrogen. The reaction tube is closed and stored, and then quickly packed into a container to prepare anhydrous ferrous chloride, 2FeCl3 H2 → 2fecec12 2HCl |
