Isoamyl butyrate, also known as isoamyl valerate, is a colorless oil with a fruity aroma. It is produced by the esterification of isoamyl alcohol and butyric acid. It is used in a wide variety of applications, including flavors and fragrances, pharmaceuticals, and food additives.
When rubber is exposed to isoamyl butyrate, it can cause degradation of the rubber due to its solvent properties. Low molecular weight hydrocarbons such as this can cause swelling or softening of the rubber, leading to weakening of the rubber material and eventual failure. Additionally, the presence of the solvent can cause the rubber to become brittle and crack under stress.
