An apparatus for continuously manufacturing organometallic compounds is provided where the apparatus has a source of a first reactant stream wherein the first reactant comprises a metal; a source of a second reactant stream; a laminar flow contacting zone for cocurrently contacting the first reactant stream and the second reactant stream; a mixing zone comprising a turbulence-promoting device; and a heat transfer zone.

Organometallic compound preparation

A method of continuously manufacturing organometallic compounds is provided where two or more reactants are conveyed to a reactor having a laminar flow contacting zone, a heat transfer zone, and a mixing zone having a turbulence-promoting device; and causing the reactants to form the organometallic compound.

A method of preparing an ultra-pure organometallic compound comprising using a microchannel device and ionic liquid solvent to produce an ultra-pure alkylmetal compound for processes such as chemical vapor deposition.

Method of preparing organometallic compounds

This invention relates to methods of removing impurities from compounds having similar volatilities to form ultra high purity compounds.

Purification process using microchannel devices

A method of preparing an ultra-pure metal amidinate compound comprising using a microchannel device for synthesis in reacting a metal halide solution with a lithium amidinate solution to produce an ultra-pure alkylmetal compound for processes such as chemical vapor deposition.
