Degree of branching octane number
WebThe degree of branching affects characteristics, such as the octane number or cetane number in petroleum chemistry. Webthe literature to predict the octane number for pure hydrocarbons of all classes, ranging in octane number from -20 to +120 with minimal information and no experimental requirements. Octane number is one of the most difficult properties to estimate or correlate because of its complex depen-dency on the molecular structure of the compound. A
