摘要: Chemical processes are disclosed that act to both regenerate and create new catalyst for iron salt catalyzed Kharasch coupling reactions during the process of creating halogenated hydrocarbons. Such processes include loading a reactor with a quantity of Fe(0) metal such as iron wire, supplying CCl4 to the reactor, supplying a phosphate compound to the reactor, supplying an alkene to the reactor, and supplying a carbonyl of Fe(0) to the reactor.

摘要: A process for obtaining higher aliphatic alcohols starting from aliphatic primary alcohols by condensation reactions is disclosed. Specifically, the process comprises a step in which an aliphatic primary alcohol is contacted in a homogeneous phase with a catalyst mixture comprising a transition metal, a base and an additive; specifically, this additive can be selected from the classes of compounds of the isoquinolines N-oxide, quinolines N-oxide, pyridines N-oxide, benzoquinones, naphthoquinones, or TEMPO. In particular, the process can be carried out by contacting said aliphatic primary alcohol with a catalyst of a recycled transition metal, with a freshly added base and with a recycled additive of the aforementioned type.

摘要: The present invention provides novel solutions to the problem of recycling carbonylation catalysts in epoxide carbonylation processes. The inventive methods are characterized in that the catalyst is recovered in a form other than as active catalyst. In some embodiments, catalyst components are removed selectively from the carbonylation product stream in two or more processing steps. One or more of these separated catalyst components are then utilized to regenerate active catalyst which is utilized during another time interval to feed a continuous carbonylation reactor.
