| Phthalonitrile Usage And Synthesis |
| Chemical Properties | Phthalonitrile is a crystalline powder having a faint grayish yellow color and a slighty aromatic odor, similar to benzonitrile. Phthalonitrile was first described in 1896 when it was isolated during the diazotization of 2-aminobenzonitrile. The compound is sparingly soluble in water (ca. 1 g/L) and soluble in acetone, nitrobenzene, and benzonitrile. It cannot be distilled and polymerizes if heated above the melting point. It is not explosive and is difficult to ignite, but the dust can explode. |
| uses | Phthalonitrile is used as a starting material for producing phthalocyanine pigments (→ Phthalocyanines), fluorescent brightners, and photographic sensitizers. |
| Uses | Phthalonitrile is used as an intermediate for chemical synthesis in the production of building blocks for colorants and coatings, life science and agricultural chemicals.?And also used as a precursor to phthalocyanine and other pigments, fluorescent brighteners, and photographic sensitizers. |
| Uses | Phthalodinitrile monomers can be polymerized thermally in the presence of small amounts of curing agents into thermosetting polymers. Phthalodinitrile is a precursor to phthalocyanine which is used as a dye or pigment. |
