Title Formation and Properties of Various Amine Complexes of Iron
Formation and Properties of Various Amine Complexes of Title Iron-Phthalocyanine (Commemoration Issue Dedicated to Professor Eiji Suito on the Occasion of his Retirement) Author(s) Kobayashi, Takashi; Kurokawa, Fumio; Uyeda, Natsu Bulletin of the Institute for Chemical Research, Kyoto Citation University (1975), 53(2): 186-199 Issue Date 1975-09-25 URL http://hdl.handle.net/2433/76604 Right Type Departmental Bulletin Paper Textversion publisher Kyoto University Bull.Inst. Chem.Res., KyotoUniv., Vol. 53,No. 2, 1975 Formation and Properties of Various Amine Complexes of Iron-Phthalocyanine Takashi KOBAYASHI,Fumio KUROKAWA, and Natsu UYEDA* ReceivedMay 12, 1975 Theformation of additivecomplexes was studied in regard to iron-phthalocyanine(FePc) dispersed in variousamines. The compositionswere determinedby means of weight-lossmeasurement and fromthe thermal behavior of the additivecomplexes as observedby DTA and X-raypowder diffraction. The decompositiontemperature ranges from 100 to 300°C,above which the crystallitesare converted into the a-formof pure FePc. Infraredabsorption spectra indicated that amine molecules are co- ordinatedto the centralmetal of FePc, whilesome extra moleculesare freelyincluded in the space of crystallattice. Fromkinetic study of visiblelight absorptionspectra, it was foundthat newabsorption appearswhen the secondmolecule of the two is combinedto the Fe atom of Pc-ring,indicating that a chargetransfer mechanism is involvedin the complexformation. INTRODUCTION The behavior of transition metal derivatives of porphyrin calls for biological signifi- cance when it forms additive complexes with various n-donor molecules which have the ability of co-ordinating to the central metal ion. In the previous paper,') we reported on the formation and properties of similar complexes of zinc-derivative of tetrabenztetraazapor- phyrin (zinc-phthalocyanine) suspended in various n-donor dispersion media. -

Polycyclic aromatic hydrocarbons (PAHs) are a significant source of secondary organic aerosol (SOA) in urban areas. We investigated the toxic effects of by-products of naphthalene SOA on lung cells. These by- products were 1,4-naphthoquinone (1,4-NQ), 2-hydroxy-1,4-naphthoquinone (2-OH-NQ), phthalic acid (PA) and phthaldialdehyde (OPA). Two different assessment methodologies were used to monitor the toxic effects: real-time cell analysis (RTCA) and the Holomonitor, a quantitative phase contrast microscope. The chemicals were tested in concentrations of 12.5 to 100 µM for 1,4-NQ and 1 to 10 mM for 2-OH-NQ, PA and OPA. We found that 1,4-NQ is toxic to cells from 25 to 100 µM (EC50: 38.7 µM ± 5.2); 2-OH-NQ is toxic from 1 to 10mM (EC50: 5.3 mM ± 0.6); PA is toxic from 5 to 10 mM (EC50: 5.2 mM ± 0.3) and OPA is toxic from 2.5 to 10 mM (EC50: 4.2 mM ± 0.5). -

This macrocyclic structure like porphyrins(biopigments) is highly coloured Phthalocyanine derivatives derived from the basic compound of (C6H4C2N)4N4 are used as light-fast blue or green pigments. The hosted metals and substituted groups result in distinct colors; phthalocyanine (blue-green), copper phthalocyanine (blue), chlorinated copper phthalocyanine (green), and sulfonated copper phthalocyanine (green). They have also been involved in the study of photosensitizer chemistry or metal complex chemistry such as transition-metal complex catalyst chemistry for uniform polymerization, luminescence chemistry and spectrophotometric analysis, organic synthesis and polymerization. Phthalocyanine pigments are used in enamels, linoleum, inks, plastics, and rubber goods. Photoisomerizable phthalocyanines are used in rewritable CD or DVD printing. Some phthalocyanines such as fluoraluminium phthalocyanine are used in cancer treatment. Due to pi-electron cloud overlaps, phthalocyanines exhibit semiconductor property. -

6.5 Phthalic Anhydride
6.5 Phthalic Anhydride 6.5.1 General1 Phthalic anhydride (PAN) production in the United States in 1972 was 0.9 billion pounds per year; this total is estimated to increase to 2.2 billion pounds per year by 1985. Of the current production, 50 percent is used for plasticizers, 25 percent for alkyd resins, 20 percent for unsaturated polyester resins, and 5 percent for miscellaneous and exports. PAN is produced by catalytic oxidation of either orthoxylene or naphthalene. Since naphthalene is a higher-priced feedstock and has a lower feed utilization (about 1.0 lb PAN/lb o-xylene versus 0.97 lb PAN/lb naphthalene), future production growth is predicted to utilize o-xylene. Because emission factors are intended for future as well as present application, this report will focus mainly on PAN production utilizing o-xylene as the main feedstock. The processes for producing PAN by o-xylene or naphthalene are the same except for reactors, catalyst handling, and recovery facilities required for fluid bed reactors. In PAN production using o-xylene as the basic feedstock, filtered air is preheated, compressed, and mixed with vaporized o-xylene and fed into the fixed-bed tubular reactors. The reactors contain the catalyst, vanadium pentoxide, and are operated at 650 to 725EF (340 to 385EC). Small amounts of sulfur dioxide are added to the reactor feed to maintain catalyst activity. Exothermic heat is removed by a molten salt bath circulated around the reactor tubes and transferred to a steam generation system. Naphthalene-based feedstock is made up of vaporized naphthalene and compressed air. -
