【 摘 要 】

The results of research of isobutyl oil (IBO) (waste of methanol production from synthesis gas) as antiknock additive to straight-run gasoline are presented. The long-term experience of using aliphatic alcohols as oxygenates is described briefly. The existing directions of application of IBO were listed. IBO contains alcohols with branched structure that have a strong detonation resistance and a calorific value comparable to hydrocarbons. A theoretical substantiation of the possibility of using IBO as additive for increases of detonation properties of gasoline is discussed. IBO as an antiknock additive to increase the octane rating of straight-run gasoline A-76 brand was investigated. It is shown that the additive of IBO allows to modernize gasoline A-76 to A-92 brand. The developed method increasing the octane number of straight run gasoline is presented.
