DISPERSAN-DISPERSAN MANNICHI DENGAN BANYAK AMINA UNTUK BAHAN BAKAR DENGAN PEMBAKARAN MENGGUNAKAN TEKANAN

摘要

Effective dispersants for use in compression ignition fuels are described as are compression ignition fuels containing such dispersants. The invention includes a fuel composition comprising: (a) a compression-ignition internal combustion fuel; and (b) a Mannich dispersant additive formed from: (1) at least one alkyl-substituted hydroxyaromatic compound; (2) at least one aldehyde; (3) a primary or secondary amine; wherein the molar ratio of the alkyl-substituted hydroxyaromatic compound to the aldehyde is in the range of from 1:1.25 to about 1:2; and wherein the molar ratio of the alkyl-substituted hydroxyaromatic compound to the amine is in the range of from about 1:1.25 to about 1:2.
