| 20110319670 | CRYSTALLIZER AND METHOD FOR PRODUCING PHENOL-BPA ADDUCT CRYSTALS - Both a crystallizer and method for the evaporative production of phenol-BPA adduct crystals are provided that achieve more uniform crystal growth while suppressing undesired crystal nucleation. The crystallizer includes a cylindrical vessel; a draft tube concentrically disposed within the cylindrical vessel such that an annular space is defined between the vessel and tube; an impeller that circulates liquid in the vessel through the draft tube and the annular space, and a plurality of nozzles mounted around an inner wall of said cylindrical vessel that introduce an evaporative coolant into the vessel. Each of the nozzles includes a discharge end disposed between about 30% and 60% of a radial extent of the annular space, and is located below an upper end of the draft tube a distance of between about 50% to 150% of the diameter of the vessel. Such a nozzle arrangement provides a consistent and uniform concentration of coolant across the surface of the boiling zone that prevents or at least reduces unwanted crystal nucleation on the inner surfaces of the vessel and promotes uniform crystal growth by providing a consistent and uniform degree of supersaturation across the annular space within the boiling zone. | 12-29-2011 |

| 20140024862 | Metabolically Engineered Cells For The Production of Pinosylvin - A genetically engineered micro-organism having an operative metabolic pathway producing cinnamoyl-CoA and producing pinosylvin therefrom by the action of a stilbene synthase is used for pinosylvin production. Said cinnamic acid may be formed from L-phenylalanine by a L-phenylalanine ammonia lyase (PAL) which is one accepting phenylalanine as a substrate and producing cinammic acid therefrom, preferably such that if the PAL also accepts tyrosine as a substrate and forms coumaric acid therefrom, the ratio Km(phenylalanine)/Km(tyrosine) for said PAL is less than 1:1 and if said micro-organism produces a cinammate-4-hydroxylase enzyme (C4H), the ratio K | 01-23-2014 |

| 20120165575 | NOVEL COORDINATION COMPLEXES AND PROCESS OF PRODUCING POLYCARBONATE BY COPOLYMERIZATION OF CARBON DIOXIDE AND EPOXIDE USING THE SAME AS CATALYST - Provided are a complex prepared from ammonium salt-containing ligands and having such an equilibrium structural formula that the metal center takes a negative charge of 2 or higher, and a method for preparing polycarbonate via copolymerization of an epoxide compound and carbon dioxide using the complex as a catalyst. When the complex is used as a catalyst for copolymerizing an epoxide compound and carbon dioxide, it shows high activity and high selectivity and provides high-molecular weight polycarbonate, and thus easily applicable to commercial processes. In addition, after forming polycarbonate via carbon dioxide/epoxide copolymerization using the complex as a catalyst, the catalyst may be separately recovered from the copolymer. | 06-28-2012 |
