CN103074126A - Ash-free gasoline antiknock - Google Patents

Abstract

The invention relates to an ash-free gasoline antiknock, which belongs to the field of gasoline fuel oil additives. The ash-free gasoline antiknock is used for boosting octane of the gasoline and reducing knocking in a fuel combustion process. The ash-free gasoline antiknock is mainly synthesized by organic acid amide, organic phenol (alcohol), ester, amine and the like with a combined chemical method.

Description

A kind of ashless gasoline antiknock

Technical field: the invention belongs to the gasoline fuel additive field, relate in particular to the ashless gasoline antiknock that does not contain metallic compound.

Background technology: along with the whole world is more and more higher to the requirement of environment, the requirement of gasoline antiknock is also become more and more stricter.Original containing metal octane promoter, as: lead, iron contained.The octane promoter of manganese maybe will be eliminated; The nonmetallic octane promoter that has, as: MTBE etc., because the meeting polluted underground water also will have the trend that is eliminated.Therefore developing new nonmetal ashless gasoline antiknock, is the problem that the world is all making great efforts.
