Detergent comprising the reaction product an amino alcohol, a high molecular weight hydroxy aromatic compound, and an aldehydye

Abstract

There is disclosed a Mannich reaction product and a reaction to create a Mannich reaction product prepared from an amino alcohol, a high molecular, weight hydroxy aromatic compound, and an aldehyde. Compositions comprising a hydrocarbon fuel and the reaction product are also disclosed.

Description

FIELD OF THE DISCLOSURE [0001] The present disclosure relates to a novel reaction to create a Mannich reaction product and the Mannich product prepared from the reaction of an amino alcohol, a high molecular weight hydroxy aromatic compound, and an aldehyde. Also provided are a fuel additive and a fuel composition using the Mannich base detergent, and benefits resulting from the use of the Mannich base detergent in the same. BACKGROUND OF THE DISCLOSURE [0002] The use of Mannich compounds is known Mannich reaction products have been taught for use as detergents in fuels, Non-volatile constituents of fuel, such as additives, form deposits on engine components. Conventional oil / fuel-soluble Mannich condensation products help to reduce deposits. [0003] Known Mannich reaction products are made from the three-component reaction of an amine, an aldehyde and a hydroxy aromatic compound. It has been disclosed to create a Mannich condensation product from alkylphenols, aliehydes, and amines....

AI Technical Summary

Benefits of technology

[0014] Further, there is also disclosed an additive package including the reaction product formed by reacting the compounds of formulas (I), (II), and (III). The additive package acts as a detergent in a fuel. Therefore, use of the additive package with a fuel reduces intake valve deposits, increases or better maintains injector cleanliness, and the like relative to a fuel without the additive

[0016] Further, there are disclosed unexpected performance benefits of using a fuel additized with the reaction product formed by reacting the compounds of formulas (I), (II), and (III). This Mannich additive unexpectedly decreases intake valve deposits and increases or better maintains fuel injector cleanliness and performance relative to a fuel that does not contain the reaction product. A relatively high molecular weight chain was found to increase the reaction product's detergency characteristics.

Problems solved by technology

However, a low molecular weight Mannich product is thought to be a poor detergent.
