    Polymer Journal, Vol. 22, No. 12, pp 1043-1050 (1990) Synthesis of Polyesters by the Reaction of Dicarboxylic Acids with Alkyl Dihalides Using the DBU Method Tadatomi NISHIKUBO* and Kazuhiro OZAKI Department of Applied Chemistry, Faculty of Engineering, Kanagawa University, Rokkakubashi, Kanagawa-ku, Yokohama 221, Japan (Received July 6, 1990) ABSTRACT: Some polyesters with moderate viscosity were synthesized by reactions of dicarboxylic acids with alkyl dihalides using 1,8-diazabicyclo-[5.4.0]-7-undecene (DBU) in aprotic polar solvents such as dimethylformamide (DMF) and dimethyl sulfoxide (DMSO) under relatively mild conditions. The viscosity and yield of the resulting polymer increased with increasing monomer concentration. Although polymers with relatively high viscosity were obtained when the reaction with p-xylylene dichloride was carried out at 70°C in DMSO, the viscosity of the resulting polymers decreased with increasing reaction temperature when the reaction with m-xylylene dibromide was carried out in DMSO.

Busch*a,b Received 29th September 2009, Accepted 18th November 2009 First published as an Advance Article on the web 15th January 2010 DOI: 10.1039/b920262e The Co/Mn/Br catalyzed oxidation of p-xylene to terephthalic acid (TPA) is demonstrated in CO2-expanded solvents at temperatures lower than those of the traditional Mid-Century (MC) process. As compared with the traditional air (N2/O2) oxidation system, the reaction with CO2/O2 ◦ mixture at 160 C and using an additional inert gas (N2 or CO2) pressure of 100 bar increases both the yield of TPA and the purity of solid TPA via a more efficient conversion of the intermediates, 4-carboxybenzaldehyde and p-toluic acid. At the same time, the amount of yellow colored by-products in the solid TPA product is also lessened, as determined by spectroscopic analysis. Equally important, the decomposition or burning of the solvent, acetic acid, monitored in terms of the yield of the gaseous products, CO and CO2, is reduced by ca.20%basedonlabeledCO2 experiments. These findings broaden the versatility of this new class of reaction media in homogeneous catalytic oxidations by maximizing the utilization of feedstock carbon for desired products while simultaneously reducing carbon emissions. 1.

  • AP-42, CH 6.11: Terephthalic Acid
    6.11 Terephthalic Acid 6.11.1 Process Description1 Terephthalic acid (TPA) is made by air oxidation of p-xylene and requires purification for use in polyester fiber manufacture. A typical continuous process for the manufacture of crude terephthalic acid (C-TPA) is shown in Figure 6.11-1. The oxidation and product recovery portion essentially consists of the Mid-Century oxidation process, whereas the recovery and recycle of acetic acid and recovery of methyl acetate are essentially as practiced by dimethyl terephthalate (DMT) technology. The purpose of the DMT process is to convert the terephthalic acid contained in C-TPA to a form that will permit its separation from impurities. C-TPA is extremely insoluble in both water and most common organic solvents. Additionally, it does not melt, it sublimes. Some products of partial oxidation of p-xylene, such as p-toluic acid and p-formyl benzoic acid, appear as impurities in TPA. Methyl acetate is also formed in significant amounts in the reaction. 6.11.1.1 C-TPA Production - Oxidation Of p-Xylene - p-Xylene (stream 1 of Figure 6.11-1), fresh acetic acid (2), a catalyst system such as manganese or cobalt acetate and sodium bromide (3), and recovered acetic acid are combined into the liquid feed entering the reactor (5). Air (6), compressed to a reaction pressure of about 2000 kPa (290 psi), is fed to the reactor. The temperature of the exothermic reaction is maintained at about 200°C (392°F) by controlling the pressure at which the reaction mixture is permitted to boil and form the vapor stream leaving the reactor (7).

It becomes especially difficult if you need to combine several metals in one framework to obtain a heterometallic node. The use of presynthesized complexes for obtaining of new heterometallic metal–organic frameworks could be essential to solve the problem of tailored synthesis. In our study we use presynthesized heterometallic pivalate complex [Li2Zn2(piv)6(py)2] to obtain new MOFs with heterometallic core as a node of the framework. We are managed to obtain four new heterometallic MOFs: [H2N(CH3)2]2[Li2Zn2(bdc)4]·CH3CN·DMF (1), [Li2Zn2(H2Br2-bdc)(Br2-bdc)3]·2DMF (2), [H N(CH ) ][LiZn (ndc) ]·CH CN (3) and [{Li Zn (dmf)(py) }{LiZn(dmf) } (NO -bdc) ]·5DMF 2 3 2 2 3 3 2 2 2 2 2 2 6 (4).

  • 7. Explosive Hazards in the Manufacture of Terephthalic Acid D. H. Derbyshire View Document
    EXPLOSION HAZARDS IN THE MANUFACTURE OF TEREPHTHALIC ACID By D. H. DERBYSHIRE, B.Sc, D.Phil.* SUMMARY The manufacture of terephthalic acid by the oxidation of p-xylene with nitric acid involves an explosion hazard. This arises since the gases evolved during the oxidation are capable of supporting the combustion of p-xylene. The paper discusses this problem and indicates how the plant has been designed to operate safely. The operation of the plant could have been safeguarded by the injection of inert gas but considerable quantities of inert gas would have been required and the process would have been costly to operate. Instead, each plant unit has been considered individually and separate safeguards were either incorporated into the design of each unit or into the method of operation. The safety of the oxidation autoclaves is ensured by keeping the partial pressure of the steam high enough to inhibit combustion. The explosion hazard in the condensing system is accepted and the unit is designed to minimise damage if an explosion occurred. Large storage tanks are necessary to enable the recovery of nitric acid to be carried out continuously and safety in these is ensured by keeping the p-xylene content below the lower limit of flammability. An account is given of some of the experimental techniques and apparatus used to obtain basic data for the design and operation of the plant. Introduction Terephthalic acid is made in large quantities by Imperial Chemical Industries Limited as an intermediate in the manu­ facture of Terylene. p-Xylene is the raw material and this is oxidised in one stage to terephthalic acid using nitric acid as the oxidising agent at elevated temperatures and pressures.

  • Biotransformation of P-Xylene Into Terephthalic Acid by Engineered Escherichia Coli
    ARTICLE Received 4 Feb 2017 | Accepted 18 Apr 2017 | Published 31 May 2017 DOI: 10.1038/ncomms15689 OPEN Biotransformation of p-xylene into terephthalic acid by engineered Escherichia coli Zi Wei Luo1 & Sang Yup Lee1,2,3 Terephthalic acid (TPA) is an important industrial chemical currently produced by energy intensive and potentially hazardous p-xylene (pX) oxidation process. Here we report the development of metabolically engineered Escherichia coli system for biological transformation of pX into TPA. The engineered E. coli strain harbours a synthetic TPA pathway optimized through manipulation of expression levels of upstream and downstream modules. The upstream pathway converts pXtop-toluic acid (pTA) and the downstream pathway transforms pTA to TPA. In a two-phase partitioning fermentation, the engineered strain converts 8.8 g pX into 13.3 g TPA, which corresponds to a conversion yield of 96.7 mol%. These results suggest that the E. coli system presented here might be a promising alternative for the large-scale biotechnological production of TPA and lays the foundations for the future development of sustainable approaches for TPA production. 1 Metabolic and Biomolecular Engineering National Research Laboratory, Department of Chemical and Biomolecular Engineering (BK21 Plus Program), Center for Systems and Synthetic Biotechnology, Institute for the BioCentury, Korea Advanced Institute of Science and Technology (KAIST), 291 Daehak-ro, Yuseong-gu, Daejeon 34141, Republic of Korea. 2 BioProcess Engineering Research Center, KAIST, Daejeon 34141, Republic of Korea. 3 BioInformatics Research Center, KAIST, Daejeon 34141, Republic of Korea.
