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. -
Retention Indices for Frequently Reported Compounds of Plant Essential Oils
Retention Indices for Frequently Reported Compounds of Plant Essential Oils V. I. Babushok,a) P. J. Linstrom, and I. G. Zenkevichb) National Institute of Standards and Technology, Gaithersburg, Maryland 20899, USA (Received 1 August 2011; accepted 27 September 2011; published online 29 November 2011) Gas chromatographic retention indices were evaluated for 505 frequently reported plant essential oil components using a large retention index database. Retention data are presented for three types of commonly used stationary phases: dimethyl silicone (nonpolar), dimethyl sili- cone with 5% phenyl groups (slightly polar), and polyethylene glycol (polar) stationary phases. The evaluations are based on the treatment of multiple measurements with the number of data records ranging from about 5 to 800 per compound. Data analysis was limited to temperature programmed conditions. The data reported include the average and median values of retention index with standard deviations and confidence intervals.

Scientific Advisory Board
OPCW Scientific Advisory Board SAB-III/1 27 April 2000 Original: ENGLISH REPORT OF THE THIRD SESSION OF THE SCIENTIFIC ADVISORY BOARD 1. Introduction 1.1 The Scientific Advisory Board (hereinafter referred to as the “Board”) held two meetings during its third session, which took place from 14 - 16 December 1999 and from 15 - 16 March 2000 in The Hague. 1.2 Dr Claude Eon of France, the Chairman of the Board, presided over its proceedings. 1.3 The Board considered the following issues: (a) adamsite; (b) analytical procedures; (c) equipment issues; (d) destruction technologies; (e) bio-medical samples; (f) future contributions of the Board to the preparation of the first Review Conference; and (g) any other business. 1.4 In preparation for its meeting the Board had received reports from its temporary working groups (TWGs) on adamsite and analytical procedures, and a report on a joint meeting of the temporary working groups on equipment issues and on chemical weapons destruction technologies. 1.5 During its meeting in December 1999, the Board received a briefing by the Deputy Director-General on the status of implementation of the Convention and on work priorities. The Board was also briefed by staff from the Verification and Inspectorate Divisions on experiences with the conduct of different types of inspection, as well as on analytical and equipment-related matters. It was further briefed on the results of an expert meeting on bio-medical samples conducted by the Secretariat in December 1999. CS-2000-1867 SAB-III/1 page 2 2. Work on substantive issues Adamsite 2.1 The Board received and discussed the draft report of the TWG on adamsite dated 7 October 1999, noted additional comments, and decided to include in its report the following considerations in relation to this matter: 2.2 Adamsite (10-chloro-5,10-dihydro-phenarsazine, code name DM, CAS registry number 578-94-9) is a yellow-green crystalline solid with a boiling point of 410ºC and a melting point of 195ºC. -

Published 2011 by John Wiley & Sons, Ltd. 2 ANALYSIS OF CHEMICAL WARFARE DEGRADATION PRODUCTS 1.1 ORGANOPHOSPHORUS NERVE AGENTS Organophosphorus (OP) type compounds, that is, deriva- tives containing the P=O moiety, were first discovered in the 1800s when researchers were investigating useful applica- tions for insecticides/rodenticides. There are many derivatives of organophosphorus compounds, however, the OP deriva- tives that are typically known as ‘nerve agents’ were discov- ered accidentally in Germany in 1936 by a research team led by Dr. Gerhard Schrader at IG Farben [1–4]. Schrader had noticed the effects and lethality of these organophosphorus compounds towards insects and began developing a new class of insecticides. While working towards the goal of an improved insecticide, Schrader experimented with numerous phosphorus-containing compounds, leading to the discovery of the first nerve agent, Tabun (or GA) (Figure 1.1). The potency of these insecticides towards humans was not realized until there was yet another accident, which involved a Tabun spill. Schrader and coworkers began experiencing symptoms, such as miosis (constriction of the pupils of the eyes), dizziness and severe shortness of breath, with numerous effects lasting several weeks [1, 4, 5]. -
