Abstract
The observation was made that virtually all octane number variations arise from 23 components present in a broad variety of gasolines. Consequently it is possible to develop a calibration set consisting of a gasoline base stock as modified by one or more of the 23 components. By measuring the octane number and near infrared spectrum of each member of the calibration set, the octane number of any sample at the site specific for the base stock may be determined from the near infrared spectrum of the sample.
