High-purity terephthalic acid: High-purity terephthalic acid. (Mitsubishi Chemical Industries Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59093029 A2 29 May 1984 Showa, 6 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C07C063-26; C07C051-265. ICA: B01J027-08; B01J031-04. APPLICATION: JP 82-200582 16 Nov 1982. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 25 Terephthalic acid (I) [100-21-0] pure enough to be used directly for polyester manuf. is prepd. by oxidn. of p-xylene (II) [106-42-3] by mol. O in HOAc at 180-230° using catalysts contg. heavy metals and/or Br, followed by addn. of more heavy metal and/or Br and further treatment with O, first at a temp. below the initial oxidn. temp., then above it. Thus, II 1, HOAc-H2O 4.5, Co(OAc)2.4H2O [6147-53-1] 0.0025, Mn(OAc)2.4H2O [6156-78-1] 0.0027, and 47% aq. HBr 0.0039 part/h were fed along with an excess of air to a Ti reactor at 200°, 18 kg/cm2 (gage), and av. residence time (t) 90 min. The crude I product stream was mixed with addnl. catalysts (0.25 times the initial catalyst feed rate), then treated with excess air at 185° and 11 kg/cm2 for t 30 min, and at 260° and 55 kg/cm2 for t 30 min, after which the mixt. was cooled to ppt. I, and centrifuged. The resulting product contained 270 ppm 4-carboxybenzaldehyde [619-66-9], compared with 360 ppm for I prepd. similarly without addn. of catalysts after initial oxidn., and 340 ppm when 25% more catalyst was added with the feed to the 1st reactor stage.

DOCUMENT TYPE: Journal CA Section: 75 (Crystallography and Liquid Crystals) Section cross-reference(s): 78 The title compd.There are some reagents with their cas registry numbers 6156-78-1 and 651027-47-3 are used in this study., {[Mn(C4H4O6)(C12H8N2)]×6H2O}n, has a linear chain structure contg. monomeric [Mn(C4H4O6)(C12H8N2)] repeat units. Each Mn ion is six-coordinate, with the two phenanthroline N atoms [Mn-N = 2.229(2) and 2.235(2) ?] and four O atoms from two tartrate anions [Mn-OCOO = 2.1252(19) and 2.1310(19) ?, and Mn-OOH = 2.2404(19) and 2.2424(19) ?] forming a seriously distorted octahedral coordination environment. Six H2O mols. exist outside every repeat unit as solvate mols. Extensive H-bonding interactions and p-p stacking of the phenanthroline moieties exist between the chains. Crystallog. data are given. .
