摘要： The invention provides for a dynamic dew point analysis method as well as an apparatus for carrying out the method wherein the method comprises: arranging a moisture containing gas in the immediate vicinity of at least two thermocouples, where one thermocouple is shielded from the gas; creating an analogous temperature change in both thermocouples and registering the temperature in both thermocouples during a cycle where the condensation point of the moisture containing gas is passed, using the different temperatures from the at least two thermocouples as input for determining the dew point according to basic thermodynamic principles.

摘要： Methods for the dehalogenation of various haloethers are disclosed, comprising providing a haloether having the formula CX'.sub.3 -[CY.sub.2 ].sub.n -O-CZ.sub.2 -CX.sub.3 in which X', Y, Z and X are specifically disclosed combinations of hydrogen, fluorine chlorine and bromine such that the molecule includes at least one reducible group, but where both portions of any ethyl groups present are not reducible. Dehalogenation of these haloethers is carried out by contacting same with a hydrogen donor comprising an amine, preferably a primary or secondary amine or a primary, secondary or tertiary alkanol amine. The amine is preferably used in combination with a catalyst, such as a varivalent metal or a salt thereof, such as copper or a copper salt.
