FAQ

What are the physical and chemical properties of Propionitrile (CAS: 1070-71-9)?

Propionitrile, also known as 2-propenenitrile (CAS: 1070-71-9), is a colorless liquid with a sharp, pungent odor. It has a molecular weight of approximately 72.07 g/mol and a boiling point of 55.7°C. Propionitrile is slightly soluble in water but miscible with most organic solvents. It is highly reactive, capable of forming imines and nitriles under certain conditions. It is also known for its volatility and flammability.

How is Propionitrile (CAS: 1070-71-9) typically synthesized?

Propionitrile is synthesized by the reaction of propylene with ammonia in the presence of a rhodium catalyst under high pressure. The process typically involves the partial reduction of propionamide to propionitrile. The yield is around 70-80%, and the selectivity towards propionitrile is high due to the use of a suitable catalyst. This method ensures a high-quality product with good purity.

What industries use Propionitrile (CAS: 1070-71-9)?

Propionitrile is used in various industries due to its reactivity and versatility. It is primarily used in the pharmaceutical industry for the synthesis of certain drugs and intermediates. Additionally, it is used in the production of polymers, particularly in the synthesis of certain types of resins and elastomers. It also finds application in the development of sensors and as a precursor in the semiconductor industry for coating and etching processes.

What precautions should be taken when handling Propionitrile (CAS: 1070-71-9)?

When handling propionitrile (CAS: 1070-71-9), it is essential to take appropriate safety precautions. Wear appropriate personal protective equipment (PPE), including gloves, goggles, and a respirator, to protect against inhalation and skin contact. Work in a well-ventilated area or a fume hood to minimize exposure. Store it in a cool, dry place away from heat and ignition sources. In case of a spill, use appropriate absorbents to contain the liquid and dispose of the waste according to local regulations. Always refer to the Safety Data Sheet (SDS) for detailed handling and emergency procedures.
