Product Usage
Adiponitrile is widely used in various industrial applications. It serves as a synthetic rubber accelerator, rust inhibitor, and detergent additive. It is also utilized as a spinning solvent for acrylonitrile, methacrylonitrile, and methyl methacrylate terpolymers, as well as a solvent for the wet and dry spinning processes of polyvinyl chloride fibers.
In addition, adiponitrile is applied in polyamide colorants, fabric bleaching auxiliaries, acetate, propionate, butyrate, and mixed ester plasticizers, as well as an extractant for aromatic compounds.
