Petroleum Ether Boiling Point. Gardless of amount. The boiling point of a substance is the temperature at which the vapor pressure of the liquid is equal to the surrounding atmospheric pressure thus facilitating transition of the material between gaseous and liquid phases. Oxidative demethylation of methyl tert-butyl ether and tert-amyl methyl ether TAME and deethylation of ethyl tert-butyl ether ETBE by CYP enzymes results in the formation of tertiary alcohols and aldehydes both potentially toxic. For instance both DMF and DMSO will boil below 50 C if the vacuum is reduced from 760 torr.

Gasoline is a petroleum-derived product comprising a mixture of liquid aliphatic and aromatic hydrocarbons ranging between C4 and C12 carbon atoms with the boiling range of 30225C. Solvents with higher boiling points such as water 100 C at standard atmospheric pressure 760 torr or 1 bar dimethylformamide DMF 153 C at the same or dimethyl sulfoxide DMSO 189 C at the same can also be evaporated if the units vacuum system is capable of sufficiently low pressure. Ligroine and paint. If the solvent or solvent mixture is properly chosen the compound will have decreased solubility at lower temperatures and the solution will precipitate crystals as it cools. Thermodynamics - Effects of work heat and energy on systems. Ideally the solute is very soluble in the solvent at its boiling.
