BUTENE CONVERSION METHOD AND MONOFLUOROBUTANE PURIFICATION METHOD

Provided is an industrially simple and cheap method for efficiently removing butene from crude monofluorobutane containing butene without causing substantial decomposition, transformation, or the like of the monofluorobutane. In a provided monofluorobutane purification method, crude monofluorobutane containing butene is brought into contact with trihalomethane in the presence of an alkali aqueous solution to convert the butene to a compound having a higher boiling point than the monofluorobutane, water is subsequently added to a reaction mixture obtained thereby to dissolve a produced salt, an organic layer is separated, and then the separated organic layer is purified by distillation.

Solvent pressure effects in free radical reactions. 2. Reconciliation of the gas and condensed phase chlorination of cyclopropane

The results reported herein demonstrate that the chemoselectivity (SH2 ring opening vs abstraction of a cyclopropyl hydrogen) associated with the free radical chlorination of cyclopropane is solvent dependent. Internal pressure is implicated as the solvent parameter responsible for the observed solvent effect. (Solvents of high internal pressure favor the SH2 process; hydrogen abstraction becomes more important in solvents of low internal pressure or in the gas phase.) Extrapolation of the solution phase results to zero internal pressure accurately predicts the gas-phase result, suggesting that the difference in chemoselectivity between the vapor- and condensed-phase reactions is attributable to internal pressure in the condensed phase medium. No evidence for the chlorine atom cage effect is found in the chlorination of cyclopropane.
