Sorry, no etymologies found.
Asphaltenes are high-molecular weight species that are insoluble in these solvents, whereas maltenes have lower molecular weights and are soluble.
Asphalts normally contain between 5 and 25% by weight of asphaltenes and may be regarded as colloids of asphaltene micelles dispersed in maltenes.
The compounds are classified as asphaltenes or maltenes according to their solubility in hexane or heptane.
