Antimony trichloride - Nature
Open Data Verified Data
colorless orthorhombic crystal, a, B, y three forms. The relative density was 3.140. Melting point 73.4 °c. Boiling point 283 °c. Strong deliquescence, micro-smoke in the air, strong corrosion. Soluble in ethanol, chloroform, carbon disulfide, benzene, acetone and other organic solvents, but also soluble in hydrochloric acid and tartaric acid solution. Dissolved in water and decomposition of Antimony oxychloride. It is soluble in anhydrous ethanol at room temperature without decomposition, and can react with ethanol to form a basic salt when heated. It reacts with hot concentrated sulfuric acid to produce hydrogen chloride and Antimony sulfate; Can be oxidized by concentrated nitric acid to antimonic acid; Can react with chloride of alkali metal and alkaline earth metal to form complex. Antimony trichloride can inhibit the corrosion of copper, iron, cobalt and nickel by strong acid, and accelerate the dissolution of zinc, cadmium, tin and chromium. Therefore, it can be used to remove zinc, cadmium, tin, chromium and other coatings on copper, iron, nickel and cobalt metals. It has a protective effect on iron in concentrated hydrochloric acid.

Antimony trichloride - Preparation Method
Open Data Verified Data
The antimony ingot was crushed into an antimony block of about 3cm, and placed in a reaction column. Chlorine gas was introduced from the top of the column to conduct a chlorination reaction, and crude antimony trichloride produced was discharged from the bottom of the column. The crude product was distilled under reduced pressure to remove antimony pentachloride, followed by arsenic removal, cooling crystallization and pulverization to obtain finished antimony trichloride product.

Antimony trichloride - Safety
Open Data Verified Data
belongs to other inorganic corrosion articles, risk code number: GB 8.1 class 81046. UN NO.1733;IMDG CODE P. 8118, Category 8.1. With glass bottles, each bottle of 0. 5kg net weight, external use of wooden box packaging, filled with vermiculite and so on. The package shall be marked with "corrosive items. Should be stored in a cool, ventilated, dry warehouse. Stay away from heat sources and fire types. To prevent moisture. It shall not be stored and mixed with cyanide, H porogen, oxidant and alkali. In the transport process to prevent rain and sun exposure. During loading and unloading, care should be taken to prevent package breakage. When there is a fire, the fire can be suppressed by water, sand and carbon dioxide fire extinguisher, and the container in the fire scene can be kept cooled by mist water. Toxicity and protection; LD50 525mg/kg (rat, oral). Antimony trichloride vapor and smoke irritate the conjunctiva, mucous membranes and skin of the eye. Can cause bronchitis, Pneumonia, pulmonary edema. This product spatters on the skin, water produced hydrochloric acid and heat can burn the skin, and can be due to antimony absorption caused by antimony poisoning systemic symptoms, such as hepatomegaly, abnormal liver function. For patients who inhale dust, they should leave the contaminated area, rest and stay warm, and seek medical treatment. When the skin is in contact with or the eyes are stimulated, they must be washed with a large amount of water, gastric lavage was repeated with tannic acid solution and proteqing solution, and the patient was sent to hospital for treatment. The maximum allowable concentration of antimony trichloride (as antimony) is 1mg/m3. Production workers should wear work clothes, wear anti-virus masks, protective gloves, etc. Because the arsenic chloride generated by the action of arsenic and chlorine in the metal antimony is highly toxic, the production equipment should be sealed and the workshop should be well ventilated.
