G:\Haps\Haps Help\Haps Help Ver 2.Wpd HAPsHelp Version 2 Using HAPsHelp HapsHelp has been created to assist manufacturers in identifying sources of hazardous air pollutants (HAPs) in their manufacturing facilities, because many manufacturers use industrial products that may contain some amount of a HAP. While there are also a smaller number of companies that either manufacture HAPs or purchase HAPs for use in a manufacturing process, these companies should have no difficulty identifying and estimating their emissions. Here’s how to use HAPSHelp to identify sources of emissions for newly listed NR445 hazardous air pollutants, and other commonly reported HAPs: 1) Review the list of newly listed NR445 air toxics (see: Appendix) . Do you recognize any as chemicals that your company either manufactures, purchases as feedstock or produces as a process byproduct. If so, you must determine if you meet the definition of a regulated emitter under the rule, and if you do, calculate your emissions. 2) If possible, cross check your database of Material Safety Data Sheets (MSDS) against the list of NR445 chemicals using both the Chemical Abstract Service (CAS) number and the chemical name. If you find that your company purchases products containing regulated HAPs, search HAPsHelp for more information about the chemical. If you do not have a MSDS database, you can use HAPsHelp to identify the types of industrial products used by your company that might contain a listed HAPs. If you have any of those products in your facility, manually check the MSDS for that product to determine if it contains the listed HAP. 3) Review the HAPsHelp chemical profile for the listed HAP to determine the likely source of emission of the chemical, and identify opportunities for emission reduction, or product substitution so you can eliminate it from your facility entirely. How to Search in HAPsHelp HAPs Help utilizes the Adobe Acrobat Find option to help you locate the chemical profile you need. This search option is usually represented by the binocular icon, but can also be found in the Edit drop-down list. Either manually enter (or block and copy) the CAS number, or the chemical name or synonym into the search box, and your cursor will move to the appropriate profile. The name and CAS numbers of HAPs included in HAPSHelp are shown on the following list: i HAPs Help Chemicals CAS# NR445 Name 98-86-2 ACETOPHENONE 108-24-7 ACETIC ANHYDRIDE 124-04-9 ADIPIC ACID 106-92-3 ALLYL GLYCIDYL ETHER 97-56-3 AMINOAZOTOULENE; 0-(2-AMINOAZOTOULENE) 3825-26-1 AMMONIUM PERFLUOROOCTANOATE 7727-54-0 AMMONIUM PERSULFATE 1309-64-4 ANTIMONY TRIOXIDE 107-13-1 ACRYLONITRILE 207-08-9 BENZO[K]FLUORANTHENE 98-88-4 BENZOYL CHLORIDE 1304-82-1 BISMUTH TELLURIDE 75-27-4 BROMODICHLOROMETHANE 75-25-2 BROMOFORM 106-99-0 1,3-BUTADIENE 25013-16-5 BUTYLATED HYDROXYANISOLE 108171-26-2 CHLORINATED PARAFFINS 532-27-4 CHLOROACETOPHENONE 108-90-7 CHLOROBENZENE (MONOCHLOROBENZENE) 2698-41-1 CHLOROBENZYLIDENE MALONONITRILE 75-68-3 CHLORODIFLUOROETHANE 75-45-6 CHLORODIFLUOROMETHANE 106-89-8 1-CHLORO-2,3-EPOXYPROPANE (EPICHLOROHYDRIN) 569-61-9 C.I.

  • Numerical Simulation of a Two-Phase Flow for the Acrylonitrile Electrolytic Adiponitrile Process in a Vertical/Horizontal Electrolysis Cell
    energies Article Numerical Simulation of a Two-Phase Flow for the Acrylonitrile Electrolytic Adiponitrile Process in a Vertical/Horizontal Electrolysis Cell Jiin-Yuh Jang * and Yu-Feng Gan Department of Mechanical Engineering, National Cheng-Kung University, Tainan 70101, Taiwan; [email protected] * Correspondence: [email protected]; Tel.: +886-6-2088573 Received: 7 September 2018; Accepted: 6 October 2018; Published: 12 October 2018 Abstract: This paper investigated the effect of oxygen holdup on the current density distribution over the electrode of a vertical/horizontal electrolysis cell with a two-dimensional Eulerian–Eulerian two-phase flow model in the acrylonitrile (AN) electrolytic adiponitrile (ADN) process. The physical models consisted of a vertical/horizontal electrolysis cell 10 mm wide and 600 mm long. The electrical potential difference between the anode and cathode was fixed at 5 V, which corresponded to a uniform current density j = 0.4 A/cm2 without any bubbles released from the electrodes. The effects of different inlet electrolyte velocities (vin = 0.4, 0.6, 1.0 and 1.5 m/s) on the void fraction and the current density distributions were discussed in detail. It is shown that, for a given applied voltage, as the electrolyte velocity is increased, the gas diffusion layer thickness decreased and this resulted in the decrease of the gas void fraction and increase of the corresponding current density; for a given velocity, the current density for a vertical cell was higher than that for a horizontal cell. Furthermore, assuming the release of uniform mass flux for the oxygen results in overestimation of the total gas accumulation mass flow rate by 2.8% and 5.8% and it will also result in underestimation of the current density by 0.3% and 2.4% for a vertical cell and a horizontal cell, respectively.

  • A Quantum Chemical Study Involving Nitrogen Mustards
    The Pharmaceutical and Chemical Journal, 2016, 3(4):58-60 Available online www.tpcj.org ISSN: 2349-7092 Research Article CODEN(USA): PCJHBA Formation enthalpy and number of conformers as suitable QSAR descriptors: a quantum chemical study involving nitrogen mustards Robson Fernandes de Farias Universidade Federal do Rio Grande do Norte, Cx. Postal 1664, 59078-970, Natal-RN, Brasil Abstract In the present work, a quantum chemical study (Semi-empirical,PM6 method) is performed using nitrogen mustards (HN1, HN2 and HN3) as subjects in order to demonstrate that there is a close relationship between pharmacological activity and parameters such as formation enthalpy and number of conformers, which could, consequently, be employed as reliable QSAR descriptors. To the studied nitrogen mustards, a very simple equation o o relating log P, ΔH f and the number of conformers (Nc) was found: log P = [(log -ΔH f + logNc)/2]-0.28. Keywords QSAR, Descriptors, Formation enthalpy, Conformers, Semi-empirical, Nitrogen mustards, Log P Introduction It is well known that lipophilicity is a very important molecular descriptor that often correlates well with the bioactivity of chemicals [1]. Hence, lipophilicity, measured as log P, is a key property in quantitative structure activity relationship (QSAR) studies. In this connection, in the pharmaceutical sciences it is a common practice to use log P (the partition coefficient between water and octanol), as a reliable indicator of the hydrophobicity or lipophilicity of (drug) molecules [1-2]. For example, relying primarily on the log P is a sensible strategy in preparing future 18-crown-6 analogs with optimized biological activity [3].

  • Preparing to Manufacture Hydrogen Peroxide
    PREPARING TO MANUFACTURE HYDROGEN PEROXIDE Part of the Hydrogen Peroxide Propulsion Guide The early laboratory preparation of hydrogen peroxide was based on the technique that Thenard used during the initial preparation of hydrogen peroxide. In this technique, barium nitrate, purified by recrystallization, was decomposed by heating in air in a porcelain retort. The resulting oxide was further oxidized by heating in a stream of oxygen to a dull red heat. The barium peroxide which formed was then dampened, ground, and dissolved in hydrochloric acid (nitric acid was used in Thenard’s initial experiments). A slight excess of sulfuric acid was then added to precipitate barium sulfate and regenerate hydrochloric acid. The procedure of barium peroxide solution and sulfate precipitation was repeated several times in the same solution to increase the peroxide concentration (concentrations of up to 33 percent by weight hydrogen peroxide could be achieved in this manner). The concentrated solution containing water, hydrogen peroxide, and hydrochloric acid, along with accumulated impurities, was cooled with ice and saturated with barium peroxide; iron and manganese impurities in the solution were then precipitated out as phosphates. The hydrochloric acid was removed by the addition of silver sulfate and the sulfate ion was removed by the subsequent addition of barium oxide. Further concentration was accomplished by vacuum distillation until “no further density increase occurs.” Thenard reported that 100 w/o hydrogen peroxide (on the basis of density data and the measurement of the volume of oxygen released) could be obtained by this technique. The first record of commercial production of hydrogen peroxide appeared in the 1865 to 1875 period.

The strain was taxonomically studied and identified as Rhodococcus rhodochrous. The nitrilase was purified, with 9.08% overall recovery, through five steps from a cell extract of the stain. After the last step, the purified enzyme appeared to be homogeneous, as judged by polyacrylamide gel electrophoresis, analytical centrifugation, and double immunodiffusion in agarose. The relative molecular weight values for the native enzyme, estimated from the ultracentrifugal equilibrium and by high-performance liquid chromatog- raphy, were approximately 604,000 + 30,000 and 650,000, respectively, and the enzyme consisted of 15 to 16 subunits identical in molecular weight (41,000). The enzyme acted on aliphatic olefinic nitriles such as crotononitrile and acrylonitrile as the most suitable substrates. The apparent Km values for crotononitrile and acrylonitrile were 18.9 and 1.14 mM, respectively. The nitrilase also catalyzed the direct hydrolysis of saturated aliphatic nitriles, such as valeronitrile, 4-chlorobutyronitrile, and glutaronitrile, to the correspond- ing acids without the formation of amide intermediates.
