She was trying to transfer up to 2 ounces (~50ml) of t-butyl lithium (pyrophoric chemical), which was dissolved in pentane from one sealed container to another by a 50 ml syringe. The barrel of the syringe was either ejected or pulled out of the syringe, causing liquid to be released. A flash fire set her clothing ablaze and spread second- and third-degree burns over 43% of her body. 2 4/24/2012 Root Causes of the Accident Poor technique and improper method Use a 50ml syringe to transfer~50 ml pyrophoric chemical Should use a 100ml syringe Should use Cannula Method for transfer of pyrophoric chemical > 50 ml Lack of proper training No safety training record Lack of supervision No follow up actions had been -
Catalysis of the Oxygen Evolution Reaction by 4–10 Nm Cobalt Nanoparticles
Topics in Catalysis https://doi.org/10.1007/s11244-018-0923-4 ORIGINAL PAPER Catalysis of the Oxygen Evolution Reaction by 4–10 nm Cobalt Nanoparticles Edward Locke1 · Shan Jiang1 · Simon K. Beaumont1 © The Author(s) 2018 Abstract Electrolysis of water is key technology, not only for clean energy production, but to ensure a continued supply of hydrogen beyond fossil resources, essential to the manufacture of many chemical goods other than fuels. Cobalt nanomaterials have been widely identified as a promising candidate for the anode (oxygen evolution) reaction in this process, but much work has focused on applied materials or electrode design. Given the importance of oxidation state changes Co(III) → Co(IV) in the accepted reaction mechanism, in this work we look at size effects in small (4–10 nm) cobalt nanoparticles, where the ease of oxidation for lower cobalt oxidation states is known to change with particle size. To discriminate between geometric and chemical effects we have compared the catalysts in this study to others in the literature by turnover frequency (widely used in other areas of catalysis), in addition to the more commonly employed performance metric of the overpotential required to produce a current density of 10 mA cm−2. Comparisons are drawn to key examples of using well defined nanomaterials (where the surface are of cobalt sites can be estimated). This has enabled an estimated intrinsic turnover rate of ~ 1 O2 mol- ecule per surface Co atom per second at an overpotential of 500 mV in the oxygen evolution reaction under typical alkaline reaction conditions (pH 14.0) to be identified. -

Synthesis and Properties of Simple and Complex Salts Of
PhD Theses SYNTHESIS AND PROPERTIES OF SIMPLE AND COMPLEX SALTS OF PERMANGANIC ACID Kótai László Institute of Materials and Environmental Chemistry Chemical Research Center, Hungarian Academy of Sciences 2006 1 1. INTRODUCTION AND AIMS Widespread applicapibility and the increased quality requirements of permanganate salts require development of new synthetic methods. The transition metal permanganates are precursors of numerous catalytically active metal-manganese oxide composites. Therefore, the exact kowledge of their structure, reactivity and the thermal decomposition characteristics of permanganate compounds is essenial to plan the properties of the decomposition products. The main target of this work was the development of new synthetic methods to prepare simple and complex salts of permanganic acid, including the preparation and the study of ammonium permanganate and some ammine-complex permanganates of transition metals such as Ag, Cu, Ni, Cd, Zn. 2. ANALYTICAL METHODS Classical inorganic analytical chemistry, IR and Raman spectroscopy, UV-VIS spectroscopy, ESR, XRD, GC-MS, single crystal X-ray and powder neutron diffractometry, TG-gas- titrimetry, TG-MS and DSC methods were used. 3. NEW RESULTS 3.1. SYNTHESES 3.1.1. Syntheses based on manganese heptoxide A method has been developed to prepare Ba, Mg, Ca, Ni, Zn, Cd, Cu(II), Al, Fe(III), Y, Ce(IV), Sm, Pr and Gd-permanganates by means of the reaction of KMnO4 with sulfuric acid monohydrate, followed by extraction of the Mn2O7 with CCl4 and the reaction of the Mn2O7 in CCl4 with catalytic amount of water and the oxide, hydroxide and carbonate of the appropriate metal. 3.1.2. Syntheses based on the metathesis reaction of KMnO4 Reaction of warm saturated solutions of NH4Cl and potassium permangnate provided Kx(NH4)1-xMnO4 (x=0.2-0.4) solid solutions instead of NH4MnO4 as it has been declared previously. -

Abstract The thesis describes a study of the reactions of a variety of manganese compounds with N204 or N205 leading to the synthesis of new manganese compounds with coordinated nitrate groups and other ligands, The aim of this work, to synthesise the first reported nitrato-complexes of manganese in an oxidation state higher than the common state (II), has been achieved, Manganese(II1) trinitrate, M~L(NO~)~,has been prepared by reaction of manganese(II1) trifluoride and dinitrogen pentoxide in dinltrogen tetroxide, Manganese (111) trinitrate is stable indefinitely below -14OC, but rapidly evolves N204 at room temperature and fumes in moist alr, The properties indicate that all nitrate groups are strongly coordinated and suggest that the compound fs polymeric with bridging nitrate groups. The bipyridyl, -o-phenanthroline, triphenylphosphine oxide and acetonitrile complexes of Mn(N0 have been prepared; all are stable at -

Owner DOC. NO. REV. DATE C.H.O SOP PYROPHORIC 2 12/16/2019 DOC. TITLE SOP FOR PYROPHORIC CHEMICALS Environmental Health & Safety STANDARD OPERATING PROCEDURES (SOP) FOR WORKING WITH PYROPHORIC CHEMICALS AT AMHERST COLLEGE ___________________________________________________________________ General Information Pyrophoric Chemicals are solid, liquid, or gas compounds that, when exposed to air or moisture at or below 54°C (130°F), can spontaneously ignite. Examples of Pyrophoric chemicals used at Amherst College Laboratories include: sodium hydride, zinc powder, and Grignard reagents. See the “Appendix” page below for a full list of Pyrophoric Chemicals. Pyrophoric chemicals are often used as catalysts in chemical reactions or as reducing and deprotonating agents in organic chemistry. Note that Pyrophoric chemicals may also be characterized by other hazards, hence, users of these chemicals may also need to refer to other SOPs that cover other hazards. In addition, each individual chemical’s Safety Data Sheet (SDS) should be consulted before they are used. _____________________________________________________________________________________ Personal Protective Equipment When working with Pyrophoric Chemicals, the following personal protective equipment (PPE) must be worn, at a minimum. Depending on the specific chemical, other forms of protection might be required. Consult the SDS for each chemical before use: Splash goggles Lab coat (Fire resistant lab coat highly recommended) Long pants Close toed shoes Gloves – Nitrile gloves adequate for accidental contact with small quantities. However, the use of fire resistant Nomex/ Leather Pilot’s gloves is highly recommended _____________________________________________________________________________________ Safety Devices All work with Pyrophoric chemicals must be done in a glove box, vacuum manifold, or any enclosed inert environment. If work must be done in a fume hood, ensure that the hood sash is in the lowest feasible position. -
