The Preston-Prausnitz method was used to estimate the solubility of chosen alkanes, alkenes, aromatic and naphtene hydrocarbons, several inorganic gases, and methanol in liquid oxygen in the temperature range 55-95 K.
Estimation of the solubility of solidified substances in liquid oxygen by the Preston-Prausnitz method
E. Szczepaniec-Ci(/ciak and B. Ciejek
As shown by the literature survey on the solubility in liquid oxygen of solidified substances, this cryogenic solvent has been investigated with greatest accuracy. The set of more than 50 substances ~ whose solubility in LO~was determined, can be divided in the following groups: alkanes which comprise methane, ethane, propane, butane, isobutane, pentane, isopentane, neopentane, hexane and decane; alkenes comprising ethylene, propylene, butylene, isobutylene, pentene-1, pentene-2, hexene-1 and octene-1 ; alkynes comprising acetylene; alkadienes comprising butadiene-1,3; halogen-hydrocarbons comprising methyl chloride, methylene chloride, chloroform, carbon tetrachloride, and 1,2-dichloroethane; ethers comprising methyl ether, ethyl ether, propyl ether, isopropyl ether, and methyl butyl ether; aromatic hydrocarbons comprising benzene; alcohols comprising methanol and ethanol; aldehydes comprising methanal and ethanal; ketones comprising acetone; amines comprising trimetylamine; inorganic gases comprising carbon dioxide, ammonia, hydrogen sulphide, nitrous oxide, nitric oxide, nitrogen dioxide, nitrogen tetraoxide, carbonyl sulphide, sulphur hexafluoride, argon, krypton and xenon; and other substances comprising carbon disulphide.
