CYANOETHYLENE - Preparation Method
Open Data Verified Data
at present the most industrial production value or propylene ammoxidation. With propylene, ammonia, air and water as raw materials, according to its quantitative ratio into the fluidized bed or fixed bed reactor, under the action of phosphorus molybdenum bismuth or antimony iron catalyst with silica gel as carrier, at a temperature of 400 to 500 ° C. And a normal pressure, acrylonitrile is formed. Then, the unreacted ammonia is removed with dilute sulfuric acid through the neutralization column, and then the gas such as acrylonitrile is absorbed with water through the absorption column to form an aqueous solution. The aqueous solution is separated from acetonitrile through the extraction column, and the hydrocyanic acid is removed in the dehydrocyanic acid column, after dehydration, distillation and acrylonitrile products, the single-pass yield of up to 75%, by-products of acetonitrile, hydrogen cyanide and ammonium sulfate.

CYANOETHYLENE - Safety
Open Data Verified Data
- This product is extremely toxic, and its toxicity to warm-blooded animals is about 1/30 of that of hydrogen cyanide. Acrylonitrile is not only toxic vapor, but also sensitive to skin toxicity when attached to the skin. The LD50 was 15mg/kg I. V. In mice and 93mg/kg in rats. Long time inhalation of dilute acrylonitrile vapor, can cause Nausea, Vomit, Head Pain, fatigue and discomfort and other symptoms. The maximum allowable concentration in the workplace is 45mg/m3, the production equipment should be sealed, and the protective equipment should be worn during operation. If acrylonitrile is applied to clothes, take off your clothes immediately and rinse with plenty of water when it is applied to the skin. It needs to be washed with running water for more than 15 minutes. If you accidentally swallow it, wash the stomach with warm saline. If poisoning, should be immediately with sodium thiosulfate, sodium nitrite intravenous injection, and consult a doctor.
- This product is packaged in an iron drum. The storage container should be sealed, the warehouse should be well ventilated to prevent sun exposure, and should be away from strong acidic substances such as sulfuric acid and nitric acid. Storage and Transportation shall be carried out in accordance with the provisions for dangerous goods.

CYANOETHYLENE - Introduction
Acrylontril is a colorless liquid with a pungent odor. It has a lower boiling point and a higher flash point, easy to volatilize. Acrylontril is insoluble in water at normal temperature, but soluble in many organic solvents.
acrylontrile has a wide range of applications. First, it is an important raw material for the synthesis of synthetic fibers, as well as for the manufacture of rubber, plastics and coatings. Secondly, acrylontrile can also be used in the manufacture of smoke-flavored roasted fuels, fuel additives, hair care products, dyes and pharmaceutical intermediates. In addition, acrylontril can also be used as a solvent, extractant and catalyst for polymerization reactions.
acrylontril can be prepared by a chemical reaction called cyanidation. This process is usually carried out by reacting propylene with sodium cyanide in the presence of distilled ammonia to produce acrylontril.
You need to pay attention to its safety when using acrylontril. The acrylnitril is highly flammable, so it is necessary to avoid exposure to open flames and high temperatures. Due to its highly toxic nature, operators should wear protective equipment such as goggles and gloves. Exposure to acrylontril for long periods or in high concentrations can cause health problems such as skin irritation, eye pain, and difficulty breathing. Therefore, it is necessary to ensure good ventilation when using, and pay attention to follow the correct operating procedures and safe operating guidelines. If contact or inhalation of acrylitril causes discomfort, seek medical attention immediately.
