Pivalonitrile(CAS: 630-18-2)

Pivalonitrile (CAS: 630-18-2) is a colorless to white crystalline solid. Its molecular weight is approximately 120.12 g/mol. It is only slightly soluble in water but highly soluble in organic solvents like ethanol and acetone. Chemically, it is relatively stable but can undergo hydrolysis under basic conditions. It is prone to nitrile hydrolysis under acidic conditions, leading to the formation of acrylonitrile and pivalic acid.

Pivalonitrile is typically synthesized by the reaction of pivaloyl chloride with sodium hydroxide in an aprotic solvent such as acetonitrile. The process involves the nucleophilic substitution of the chloride ion by the hydroxide ion, followed by deprotonation to form the nitrile. This reaction is conducted under anhydrous conditions to prevent hydrolysis and requires careful control of pH and temperature to achieve high selectivity and yield.

Pivalonitrile (CAS: 630-18-2) is used in various industries. It serves as a key intermediate in the production of compounds for pharmaceuticals, where it is used in the synthesis of drugs. Additionally, it is utilized in the polymer industry for making special plastics and in the electronics industry for fabricating semiconductor materials. Its presence in sensors and other electronic devices also highlights its importance.

When handling Pivalonitrile (CAS: 630-18-2), it is essential to use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood to minimize inhalation risks. Spills should be handled carefully, and the material safety data sheet (MSDS) should be consulted for specific spill cleanup procedures. Ingestion and inhalation are the primary health risks, so it is crucial to avoid contact with skin and eyes.
