Prionil™ is a leading specialty nitrile, commonly known as propionitrile, which serves as a building block to make many key intermediates used in agricultural, industrial, personal care and other applications.

Prionil™ (CH3-CH2-C≡N), also known as propionitrile, ethyl cyanide or propanenitrile, is a colorless liquid that is water-soluble and miscible in alcohol, ether and acetone.

Prionil™ has similar solvency properties to acetonitrile and can be a viable substitute in closed systems where solvent exposure is minimal. Prionil™ may be a more cost-efficient option than acetonitrile in some applications.

Ascend is uniquely positioned as a large-scale producer and global distributor of high-purity Prionil.

Prionil™ applications

In addition to its use as a solvent, Prionil serves as a common intermediate for organic syntheses, such as the Houben-Hoesch reaction, and as a reaction or crystallization solvent and in the production of fragrances, flavorings, amines and pharmaceuticals, such as ketoprofen. Prionil also can be used to manufacture amines, acids, amides and ketones.

Prionil is applied as an asphaltene inhibitor/dispersant additive at 3-6 percent range to prevent asphaltene/tar precipitates from crude oil or residual fuel oil. Prionil can be used along with other common asphaltene inhibitors/dispersants as a co-additive in aromatic and aliphatic diluents. Prionil is a highly economical solution to enhancing flow, reducing drag and potentially increasing kinematic viscosity. Prionil stabilizes asphaltene in the presence of alkanes, thus preventing fouling and precipitation in pipes, pumps and heat exchangers.
