Abstract
The present invention relates to an unleaded gasoline additive which is compounded from ferrocene, polyisobutylene butane diimide, polyisobutene barium salt, benzotriazole fatty acid ammonium salt, lubricant oil and solvent. The additive has the advantages of little dose, low cost and convenient use, and also has the advantage that the octane number can be raised to 3 to 5.
Description
The present invention relates to a kind of anti-knock additive for lead-free gasoline and preparation method.
Existing gasoline majority as octane promoter, because tail gas contains lead, causes environmental pollution with tetraethyllead, therefore this doped fuel is just disabled, and white gasoline is by change refinery device on the one hand, and catalytic reforming improves octyl, adopts the way of broad variety chemical additive on the other hand, for example, by the methyl tertiary butyl ether of adding antiknock component, this method, additive amount is up to about 15%, therefore increase gasoline cost, troublesome poeration.
Purpose of the present invention is the shortcoming and deficiency in order to overcome above-mentioned prior art just, and a kind of antiknock function that has is provided, and the addition for leadless gasoline of nontoxic, safety, good stability, thus can reach the antiknock standard, also reduce cost, provide condition for promoting the use of no lead oil.
The present invention also provides the preparation method of this additive.
Technical scheme of the present invention realizes by following technical proposal:
Anti-knock additive for lead-free gasoline is characterized in that it is made by the following weight proportion raw material:
