cracking| Chemical reaction in which a large alkane molecule is broken down by heat into a smaller alkane and a small alkene molecule. The reaction is carried out at a high temperature (600°C/100°F or higher) and often in the presence of a catalyst. Cracking is a commonly used process in the petrochemical industry. |
| It is the main method of preparation of alkenes and is also used to manufacture petrol from the higher-boiling-point fractions that are obtained by the fractional distillation of crude oil (unrefined petroleum). |
