Abstract
A method for recovering liquid chlorine derivatives of hydrocarbons resides in applying the chlorine derivatives of hydrocarbons to the preheated surface of an inert liquid, the temperature of the inert liquid exceeding the boiling temperature of the chlorine derivatives of hydrocarbons.

A method for recovering liquid chlorine derivatives of hydrocarbons from an impure liquid containing impurities that are less volatile than said liquid chlorine derivatives, comprising:
- heating a second liquid which is chemically inert and has a substantially higher vapor pressure relative to said impure liquid, and in which said impurities are substantially soluble, to a temperature below the vaporization temperature of said impurities, but above the vaporization temperature of said derivatives, contacting said impure liquid with the surface said second liquid thereby recovering a substantially pure vapor of said derivatives, and substantially retaining the impurities in said second liquid.
A method for recovering a desired liquid component from an impure liquid containing impurities that are less volatile than said desired liquid component, comprising:
- heating a second liquid which is chemically inert and has a substantially higher vapor pressure relative to said impure liquid, impurities are substantially soluble, to a temperature below the vaporization temperature of said impurities, but above the vaporization temperature of said desired liquid component, contacting said impure liquid with the surface said second liquid, thereby recovering a substantially pure vapor of said desired liquid component, and substantially retaining the impurities in said second liquid.
