摘要: Abstract The dispersion of asphaltene in heptane by different oil soluble amphiphiles was investigated. Alkyl phenols show good peptizing properties and partially lose their capacity when oxyethylenic groups are incorporated into the molecule. Primary aliphatic amines also some ability to disperse asphaltene, but long chain alcohols alkyl benzenes rather inefficient. Asphaltene solutions toluene containing less sensitive precipitation addition low molecular weight alkanes. adsorption onto quartz reduced amphiphiles.
