A SIMPLE LOW-PRESSURE TO MEDIUM-PRESSURE HYDROGENATION MANIFOLD

A hydrogenation/reactive gas manifold designed for rapid screening of a wide range of reaction conditions on limited amounts of material is described, The manifold delivers reactive gas to four independent reac tor ports, each equipped with inerting, pressurizing, and venting valv es, as well as thermocouple capability, Magnetic stirring and bath/man tle temperature control are used in the individual reactions; the reac tion vessels are available in a wide range of sizes, Delivery of diffe rent pressures of reactive gas to the individual reactions is enabled by insertion of in-line regulators between ports. The modular nature o f the design allows additional reaction ports to be added as needed, T he manifold accommodates reaction pressures of up to 60 psig.
