5.1 Exposure data. 1,3-Butadiene is a monomer used in high volume in the manufacture of a wide range of polymers, including styrene butadiene rubber, polybutadiene, nitrile rubber, acrylonitrile butadiene styrene resins and styrene butadiene latexes. It is also an intermediate in the production of various other chemicals.. Occupational exposure to 1,3-butadiene occurs in the production of monomeric 1,3-butadiene and of 1,3-butadiene-based polymers and 1,3-butadiene-derived products. The mean full-shift, time-weighted average exposure levels measured for workers in these industries have usually been below 10 ppm [22 mg/m3], although that level may be exceeded during some short-term activities. Recent data from monomer extraction and styrene butadiene rubber plants showed lower average concentrations (, 5 ppm [, 11 mg/m3]. 1,3-Butadiene is not usually found at detectable levels in workplace air during manufacture of finished rubber and plastic products. The general population may be exposed to ...
1,3-Butadiene is a general air pollutant associated with combustion of organic matter and is also an extensively used monomer in polymer production. The cancer risk estimation of 1,3-butadiene is encumbered with large uncertainties. Extrapolation from tumour frequencies in long-term animal tests has led to a relatively high figure for the risk associated with 1,3-butadiene exposure. This is mainly based on observations of very high tumour incidences in butadiene-exposed mice, which in this respect are about 100 times more sensitive than rats. It has been hypothesized that a high cancer risk from 1,3-butadiene could be associated with its metabolism to the bifunctional 1,2:3,4-diepoxybutane (DEB) which, in comparison with monofunctional epoxides, 1,2-epoxy-3-butene (EB) and 1,2-epoxy-3,4-butanediol (EBdiol), is a highly effective mutagen, i.e. cancer initiator. Measurement of in vivo doses of DEB is therefore essential for the risk assessment of 1,3-butadiene. Reaction products with hemoglobin ...
The chemical kinetics of 1,3-butadiene (1,3-C4H6) are important because 1,3-butadiene is a major intermediate during the combustion of real fuels. However, there is only limited information on the chemical kinetics of 1,3-butadiene combustion, which has applications in several combustion schemes that are currently being developed, including spark-assisted homogeneous charge compression ignition and fuel reformate exhaust gas recirculation. In the present work, the ignition delay times of 1,3-butadiene mixtures has been investigated using pressure data. Oxidation of 1,3-butadiene/oxygen mixtures diluted in argon or nitrogen at equivalence ratios (Φ) of 0.3 behind reflected shock waves has been studied at temperatures ranging from 1100 to 1300K and at pressures ranging from 1 to 2atm. Reaction progress was monitored by recording concentration time-histories of 1,3-butadiene and OH* radical at a location 2cm from the end wall of a 13.4m long shock tube with an inner diameter of 14cm. 1,3-Butadiene
The present invention relates to a method of preparing butadiene and a device for preparing the same. According to the present invention, when butadiene is prepared by oxidative dehydrogenation of butene, unlike conventional methods, in which nitrogen is used as a diluent gas and an absorption method is used to separate butadiene from reaction products, butane is used as a diluent gas and a condensation method, in which butadiene is liquefied and separated from reaction products using a low-temperature refrigerant or cooling water, is used. In addition, an absorption method of recovering all hydrocarbons from an upper stream generated in a condensation process is used, so that loss of hydrocarbons is minimized. Therefore, the method and device of the present invention may provide high-purity butadiene while reducing raw material costs, production costs, and energy consumption, thereby improving economic efficiency of processes.

Butadiene is a material indispensable to synthetic rubber, and it is currently produced from a byproduct of ethylene that is produced from naphtha. That is, naphtha is vital for the production of butadiene that is an ingredient of tire. As the production cost of shale gas decreases, shale gas will grow more popular as the raw material to produce ethylene. Production of ethylene using shale gas does not produce butadiene. More specifically, growing popularity of shale gas decreases the supply of butadiene and increases the cost of tire production. ...

Dissociative double-photoionization of butadiene in the 25-45 eV energy range has been studied with tunable synchrotron radiation using full three-dimensional ion momentum imaging. Using ab initio calculations, the electronic states of the molecular dication below 33 eV are identified. The results of the measurement and calculation show that double ionization from π orbitals selectively triggers twisting about the terminal or central C-C bonds. We show that this conformational rearrangement depends upon the dication electronic state, which effectively acts as a gateway for the dissociation reaction pathway. For photon energies above 33 eV, three-body dissociation channels where neutral H-atom evaporation precedes C-C charge-separation in the dication species appear in the correlation map. The fragment angular distributions support a model where the dication species is initially aligned with the molecular backbone parallel to the polarization vector of the light, indicating a high probability ...
The reaction kinetics of 1,3-butadiene with Criegee Intermediate (CH2OO, CI) was investigated over T = 200-400 K using the CCSD(T)/aug-cc-pVTZ//B3LYP/6-311G (d, p) level of theory. Reaction pathways involving distinguished conformational addition variants of both the reactants proceeds via a 1,3-dipolar cycloaddition to form the SOZ. The effect of temperature suggested that, the contribution by the inner-facing TSs decreases, while outer-facing reaction channels become more significant, as the temperature increases. At low pressures, the effect of pressure was more prominent at temperatures close to 200 K. However, at 760 Torr, the effect was insignificant over the complete temperature range ...

Aberrant transforming development aspect-β (TGF-β) has an important function in the introduction of cancer such as for example tumor metastasis and invasion. motility in a variety of malignancy cells were dose-dependently decreased by LY2109761. TGF-β1 increased FN MMP-2 and MMP-9 expression in HCC1806 TNBC cells. TGF-β1-induced MMP-9 expression was decreased by both a MEK inhibitor UO126 and a smad3 inhibitor SIS3. Induction of FN and MMP-2 by TGF-β1 was just decreased by SIS3. Overexpression of smad3 significantly increased FN MMP-2 and MMP-9 expression. Interestingly ZER significantly suppressed TGF-β1-induced FN MMP-2 and MMP-9 expression in HCC1806 cells. In addition ZER completely decreased TGF-β1-induced the phosphorylation of smad3. Finally we observed that ZER suppressed the tumorigenecity such as tumor volume weight Ki67 expression and metastasis in TNBC cells xenograft models. Taken together we exhibited that ZER suppresses TGF-β1-induced FN MMP-2 and MMP-9 expression through ...

While one elevated result of 1,3 butadiene was found in the first round of monitoring, overall results show the toxics being tested were below levels of concern and the EPA will not continue monitoring. ...
Within the framework of the FP7 project CoPIRIDE, funded by the EU, novel process operations have developed in order to enable significant process intensification. High-throughput devices allow a compact, modular process design, so that the whole process can be installed inside a standard container. This concept provides a faster response to the market demands and allows shipping of the containers to places where educts are cheap and available, or the products required [1].. The often used multipurpose batch reactors allow a high number of different chemical reactions, but they are not optimized for a special chemistry and their handling provokes accidents [2]. Thus, stirred tank reactors are not feasible for fast exothermic reactions [3]. Microfluidic reactors are characterized by their enhanced heat and mass transfer rates, which is useful when researching an exothermic reaction [4]. Several working groups, e.g., Bally et al. [5] or Commenge et al. [6] have examined the advantages and the ...

An efficient adsorbent for butadiene was synthesized via soft hydrothermal treatment (2 h in boiling water followed by 1 h calcination at 573 K) of industrial Na-X. The adsorption capacity of the zeolite was studied in the low concentration range (20-300 ppmv). Whereas original Na-X presents a very small adsorption, its treated counterpart shows a large capacity. The characterization of the zeolite suggests that the soft hydrothermal treatment dealuminates the zeolite leaving behind new OH-groups responsible for the adsorption of butadiene on the zeolite lattice. The adsorption isotherms were determined for the hydrothermally treated zeolites and the results were found to be consistent with the Dubinin-Astakhov (D-A) model. The adsorption enthalpy of butadiene on the treated Na-X was obtained from the D-A equation and from the modeling of temperature-programmed desorption profiles. Both methods gave a value of −45 kJ mol−1 suggesting chemical interactions of butadiene with the zeolite ...
