Box 19395-4697, Iran _____________________________________________________________________________________________ ABSTRACT 3-Nitrophthalic anhydride was reacted with urea and cobalt salt in nitrobenzene under N 2 at 185°C and cobalt- tetraanitrophthalocyanine (CoTNP) was produced. Cobalt-tetraaminophthalocyanine (CoTAP) was produced by reduction of CoTNP caused by Sodium borohydride under N 2(g). CoTAP and chloromethylpolystyrene was refluxed in nitrobenzene or DMF at 180 oC for 12h. The mixture was cooled down to reach the room temperature and then solvent removed and the resulting precipitate was washed with water to remove excess CoTAP, and dried it to get a light green solid (CoTAP-linked-polymer). Kaywords Phthalocyanines, Cobaltetraminophthalocyanine, CoTAP ,Phthalocyanines linked polymer. _____________________________________________________________________________________________ INTRODUCTION Phthalocyanines are of interest not only as model compounds for the biologically important porphyrins but also because the intensely colored metal complexes are of commercial importance as dyes and pigments [1], the copper derivatives being an important blue pigment [2].

  • 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.

  • Phenolphthalein As Organic Teaching Materials: Small-Scale Preparation and Modeling for Some Functional Dyes
    Chemical Education Journal (CEJ), Vol. 13, No. 1 /Registration No. 13-11/Received July 29, 2009. URL = http://chem.sci.utsunomiya-u.ac.jp/cejrnlE.html Phenolphthalein as Organic Teaching Materials: Small-scale Preparation and Modeling for Some Functional Dyes AMIMOTO Kiichi* and KOGA Nobuyoshi Department of Science Education, Graduate School of Education, Hiroshima University, 1-1-1 Kagamiyama, Higashi-Hiroshima 739-8524, Japan *[email protected] Keywords: Organic dyes, teaching materials, phenolphthalein, small-scale experiment, modeling of functional materials Abstract Further possibilities for utilizing phenolphthalein as the sophisticated teaching materials were reinvestigated. It was proposed to use p-toluenesulfonic acid as the acid catalyst for the synthesis of phenolphthalein in conventional-scale and small-scale experiments in order to increase the reproducibility and to simplify the extraction procedures. Simplified model experiments for demonstrating the functionality of organic dyes were also developed using phenolphthalein and its derivatives. The practical usefulness of these experiments in chemistry courses at high schools was discussed. Introduction It is generally accepted that chemical changes accompanying with dramatic color changes serve to strengthen students’ enthusiasm and interest in studying chemistry. Various reaction systems which indicate such color changes have been continuously investigated for developing effective teaching materials [1-2]. The proton dissociation equilibrium of phenolphthalein (Scheme 1a), which indicates the color change between colorless and red-purple by the equilibrium shift, is one of the most popular color change phenomena for high school students, due to the utilizations as an acid-base indicator for neutralization titration, fountain of ammonia, and so on [3-4].

  • Benzyl Butyl Phthalate Or BBP)
    Toxicity Review for Benzyl­n­butyl Phthalate (Benzyl Butyl Phthalate or BBP) Introduction Benzyl butyl phthalate (BBP) is a man‐made phthalate ester that is mostly used in vinyl tile (CERHR, 2003). BBP can also be found as a plasticizer in polyvinyl chloride (PVC) for the manufacturing of conveyor belts, carpet, weather stripping and more. It is also found in some vinyl gloves and adhesives. BBP is produced by the sequential reaction of butanol and benzyl chloride with phthalic anhydride (CERHR, 2003). The Monsanto Company is the only US producer of BBP (IPCS, 1999). When BBP is added during the manufacturing of a product, it is not bound to the final product. However, through the use and disposal of the product, BBP can be released into the environment. BBP can be deposited on and taken up by crops for human and livestock consumption, resulting in its entry into the food chain (CERHR, 2003). Concentrations of BBP have been found in ambient and indoor air, drinking water, and soil. However, the concentrations are low and intakes from these routes are considered negligible (IPCS, 1999). Exposure to BBP in the general population is based on food intake. Occupational exposure to BBP is possible through skin contact and inhalation, but data on BBP concentrations in the occupational environment is limited. Unlike some other phthalates, BBP is not approved by the U.S. Food and Drug Administration for use in medicine or medical devices (IPCS, 1999; CERHR, 2003). Based on the National Toxicology Program (NTP) bioassay reports of increased pancreatic lesions in male rats, a tolerable daily intake of 1300 µg/kg body weight per day (µg/kg‐d) has been calculated for BBP by the International Programme on Chemical Safety (IPCS) (IPCS, 1999).

This is one of a series of experiments designed to determine whether selected chemicals have the capacity to produce cancer in animals. Negative results, in which the test animals do not have a greater incidence of cancer than control animals, do not necessarily mean that the test chemical is not a carcino­ gen, inasmuch as the experiments are conducted under a limited set of circumstances. Positive results demonstrate that the test chemical is carcinogenic for animals under the conditions of the test and indicate that exposure to the chemical is a potential risk to man.
