Abstract
The invention relates to a polyisobutene amine detergent dispersant without hydroxyl of R-X in the technical field of petrochemical industry, wherein R is polyisobutene group, the number average molecular weight of the R is Mn500-1800 and the molecular distribution Mw/Mn is 1.4-3, the tail Alpha-double-bond rate is more than 50 percent; X is an organic gene containing amino group or amine group; and meanwhile, the structure formula is R-X. The polyisobutene amine has better detergent dispersing property and low production cost, can be widely applied to motor petrol and fuel additive of a light diesel engine, and is especially used for keeping an air admission valve and a carburetor or spraying system clean and is used as an ash-free detergent additive of lubricating oil.
Description
Technical field
The present invention relates to the petrochemical technology field, especially a kind of PIBA of not hydroxyl.
Background technology
PIBA is as a kind of surfactant, has multiple functions such as peace and quiet, dispersion, breakdown of emulsion.It can disperse the settling that oxidation in the gasoline forms or be solubilized in the gasoline, stops them to be deposited on the petrolic key position, as nozzle, intake valve, combustion chamber etc.; And for the settling that has formed at these positions, purification agent in the gasoline can strip down them from the metallic surface, dispersion, peptization make the effect at these positions recover or reach new car mechanical parameter state, thereby recover the original design parameter of automobile in gasoline.PIBA is the main raw material of production the 4th generation cleaning dispersant for gasoline, that gasoline cleaning agent has is peace and quiet, the composite gasoline additive of dispersion, antioxygen and rustless property, add the generation that can suppress prime the fuel system inside deposition thing in the motor spirit, the oxidates that has generated can be disperseed rapidly, remove again, and then guarantee that the motor car engine dynamic property normally brings into play, the combustionproperty of fuel oil is improved, pollutents such as CO in the exhaust emissions are reduced greatly, thereby play the purifying city air, reduce the auto repair expense, the effect of fuel-economizing.Simultaneously, gasoline cleaning agent itself also is a kind of multi-functional compound fuel additive, and burning can not produce any ash content, automobile component is not had detrimentally affects such as any burn into swelling.
The production cost height of existing PIBA, complex manufacturing need be further next perfect, reduces its production cost, improves its application performance.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of polyisobutene amine product of not hydroxyl is provided, this products production cost is low, and result of use is good.
The present invention is achieved through the following technical solutions:
A kind of polyisobutene amine product, the number-average molecular weight of the R of this product is
=500～1800 and molecular distribution
Be 1.4～3, terminal α-two key rates greater than 50% polyisobutenyl structural formula are:
Wherein, X contains amino organic group.
