    Abstract: PROBLEM TO BE SOLVED: To provide a reactor system useful for conducting reactions including a gas phase and a liquid phase.SOLUTION: A liquid-gas phase reactor system including a slinger located in an upper section (headspace region) of a reaction vessel. The slinger comprises an upper horizontal surface including a plurality of vertically raised vanes extending radially outward along a curved path which effectively distribute liquid about the reactor vessel. A method for conducting an oxidation reaction using the liquid-gas phase reactor system is also disclosed. The disclosed reactor system and method have a broad range of applications but are particularly suited for the production of terephthalic acid.

    Abstract: A system for aerobic fermentation includes a vessel, an aeration system including a gas sparger fluidly coupled to the vessel to introduce a compressed gas to an internal volume of the vessel, and a recirculation loop fluidly coupled to an outlet of the vessel. The recirculation loop includes an eductor fluidly coupled to an oxygen-containing gas source, a static mixer downstream of the eductor, a heat exchanger downstream of the eductor, and a distributor downstream of the heat exchanger. The distributor is fluidly coupled to the vessel. The aeration system provides mixing and oxygen mass transfer to the fermentation composition in the vessel. The fermentation composition passes through the eductor, static mixer, heat exchanger, and distributor of the recirculation loop, and back into the vessel. Oxygen is transferred from an oxygen containing gas to the fermentation composition and heat is removed from the fermentation composition in the recirculation loop.

    Abstract: Please be informed that the "follow up required item" does not work properly. For TOC and SL indication there is a follow-up required item although there is no warning in Bibadmin. See following example : A vinyl monomer polymerization inhibitor composition comprising a liquid mixture comprising a vinyl monomer and a polymerization inhibiting effective amount of a captive polymerization inhibitor, wherein the composition lacks a fugitive polymerization inhibitor of polymerization of the vinyl monomer and the captive polymerization inhibitor independently is characterizable as being an inhibitor of polymerization of the vinyl monomer and polymerization of the vinyl monomer is inhibited by the captive polymerization inhibitor, and wherein the captive polymerization inhibitor is a compound of formula (I): or a first acid addition salt thereof, wherein R1 is hydrogen or (C1-C3)alkyl.
