The content of neutral oxygen compounds and hydrocarbons did not achieve even a half of that present in semicoking oil (except liquid product obtained in superheated dimethyl ketone medium) indicating their sufficient reserve in nondecomposed thermobitumen.
Other solvents, especially diethyl ether and dimethyl ketone produce, thanks to their chemical effects, both odd- and even-numbered homologous in practically equal quantities.
Benzene, diethyl ether, ethanol, n-hexane, dimethyl ketone and water were used as solvents at liquefaction of kerogen-70.
Besides, diethyl ether, n-hexane and dimethyl ketone are volatile at room temperature already.
6%, being lowest for water and highest for dimethyl ketone.
