What is a ammoxidation process?
In chemistry, ammoxidation is an industrial process for the production of nitriles using ammonia and oxygen. The usual substrates are alkenes. It is sometimes called the Sohio process, acknowledging that ammoxidation was first discovered by Standard Oil of Ohio in 1957.
How do you make acrylonitrile?
Acrylonitrile is manufactured by combining propylene, ammonia, and air in a process called ammoxidation. During ammoxidation, propylene, ammonia and air are fed through a catalyst at a high temperature.
What are the uses of acrylonitrile?
Acrylonitrile is used in many industries. It is used to make certain plastics, rubbers, and chemicals, and in the past, as a pesticide. Some examples of workers at risk of being exposed to acrylonitrile include the following: Workers involved in the manufacturing of acrylic fibers and plastics.

What acrylonitrile does to the body?
* Exposure to Acrylonitrile can cause weakness, headache, dizziness, confusion, nausea, vomiting, and can lead to death. * Repeated exposure can irritate the nose causing discharge, nosebleeds, and sores inside the nose. * Acrylonitrile may affect the liver.
What elements make up acrylonitrile?
ABS stands for Acrylonitrile Butadiene Styrene. ABS is an impact-resistant engineering thermoplastic & amorphous polymer. ABS is made up of three monomers: acrylonitrile, butadiene and styrene: Acrylonitrile: It is a synthetic monomer produced from propylene and ammonia.
Why is acrylonitrile harmful?
Is acrylonitrile a hazardous substance?
Acrylonitrile (CH₂=CHCN) is a toxic, colorless to pale-yellow liquid, harmful to the eyes, skin, lungs, and nervous system. It may cause cancer. Workers may be harmed from exposure to acrylonitrile. The level of exposure depends upon the dose, duration, and work being done.
What does acrylonitrile smell like?
Acrylonitrile is a clear, colorless or slightly yellow liquid that is highly volatile and toxic. Acrylonitrile vapor is heavier than air. It has a pungent odor of onion or garlic that does not provide adequate warning of hazardous levels. Acrylonitrile is poisonous by inhalation, ingestion or skin contact.
What is the hazard of acrylonitrile?
How do you clean acrylonitrile?
Liquids containing acrylonitrile may be collected by vacuuming with an appropriate system. If a vacuum system is used, there should be no sources of ignition in the vicinity of the spill, and flashback prevention devices should be provided.
Is acrylonitrile a carcinogen?
Cancer Hazard * Acrylonitrile is a PROBABLE CARCINOGEN in humans. There is some evidence that it causes lung cancer in humans and it has been shown to cause brain, mammary, and stomach cancer in animals.
