Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 1572-52-7, name is 2-Methylenepentanedinitrile, This compound has unique chemical properties. The synthetic route is as follows., name: 2-Methylenepentanedinitrile
a. 426 g (4 moles) of 2-methyleneglutaronitrile, 264 g (4 moles) of cyclopentadiene, 4 g of hydroquinone and 500 ml of benzene are heated in a pressure autoclave at 160 and under a maximum pressure of 3 bars, with stirring, for 10 hours. The mixture obtained after cooling is concentrated in vacuo (ca. 12 Torr), the residue twice extracted with 1.5 liters of petroleum ether each time and then extracted in high vacuum. The crude product is obtained as colourless oil, B.P. 115-128/0.03 Torr, which is dissolved in 300 ml of ethanol. On storage of this solution in a refrigerator overnight, there crystallises 2-exo-cyano-5-norbornene-2-endo-propionitrile, M.P. 40-42.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 1572-52-7.
