  • Working with Hazardous Chemicals
    A Publication of Reliable Methods for the Preparation of Organic Compounds Working with Hazardous Chemicals The procedures in Organic Syntheses are intended for use only by persons with proper training in experimental organic chemistry. All hazardous materials should be handled using the standard procedures for work with chemicals described in references such as "Prudent Practices in the Laboratory" (The National Academies Press, Washington, D.C., 2011; the full text can be accessed free of charge at http://www.nap.edu/catalog.php?record_id=12654). All chemical waste should be disposed of in accordance with local regulations. For general guidelines for the management of chemical waste, see Chapter 8 of Prudent Practices. In some articles in Organic Syntheses, chemical-specific hazards are highlighted in red “Caution Notes” within a procedure. It is important to recognize that the absence of a caution note does not imply that no significant hazards are associated with the chemicals involved in that procedure. Prior to performing a reaction, a thorough risk assessment should be carried out that includes a review of the potential hazards associated with each chemical and experimental operation on the scale that is planned for the procedure. Guidelines for carrying out a risk assessment and for analyzing the hazards associated with chemicals can be found in Chapter 4 of Prudent Practices. The procedures described in Organic Syntheses are provided as published and are conducted at one's own risk. Organic Syntheses, Inc., its Editors, and its Board of Directors do not warrant or guarantee the safety of individuals using these procedures and hereby disclaim any liability for any injuries or damages claimed to have resulted from or related in any way to the procedures herein.

  • Attachment 3-1 Guidance for Developing Ecological Soil
    Attachment 3-1 Guidance for Developing Ecological Soil Screening Levels (Eco-SSLs) Eco-SSL Standard Operating Procedure (SOP # 1): Plant and Soil Invertebrate Literature Search and Acquisition OSWER Directive 92857-55 November 2003 This page intentionally left blank OVERVIEW Currently, there is a lack of clear guidance in setting terrestrial effect thresholds when conducting risk assessments. Without an EPA-approved, peer-reviewed, ecologically-based terrestrial effect database, the process to develop thresholds is problematic both to EPA, other federal agencies, states, and concerned private parties. Identification of published toxicity studies on invertebrates, microbial processes and plants is a key step in the derivation of benchmarks. The purpose of the Task Group 4, Standard Operating Procedure Number 1: Literature Search and Acquisition (referred to as TG4-SOP#1) is to document procedures used to identify and acquire potentially relevant toxicology literature for use in setting ecological soil screening levels. The literature search strategy is designed to locate worldwide terrestrial toxicity literature that includes the effects of chemicals of concern on terrestrial soil-dwelling invertebrates and plants. The literature acquisition process is designed to ensure timely acquisition of relevant publications. LITERATURE IDENTIFICATION Potentially relevant literature for developing ecological soil screening levels (Eco-SSLs) is identified by examining hard copies of relevant journals, bibliographies and guidance publications and through the use of a comprehensive computerized literature search strategy. These procedures are designed to locate worldwide terrestrial toxicology literature that includes the effects of specific toxic substances with an emphasis on exposure via soil. Paper-based Literature Identification The paper-based literature identification process includes the scanning of relevant review article bibliographies and key journals held in the U.S.

Prepared under Contract No, NAS1-7418 by ELECTRO-OPTICAL SYSTEMS, INC A Xerox Company for NATIONAL AERONAUTICS AND SPACE ADMINISTRATION ABSTRACT Trial syntheses of beryllium Grignards yielded insufficient quantities of material required for the successful electrodeposition of beryllium. Aluminum-alloy and hardened-aluminum plating baths were developed through the use of inorganic and organic compound additives to an aluminum plating bath (AN1 and LiAtH in diethyl 3 4 ether). The ultimate yield strength of the aluminum deposits from 2 the improved baths was in the range of 145 - 228 MN/m (21K to 33K psi). A voltammetric technique using a triangular waveform was used to scan a large number of electrolytes in uncovering the im- proved plating baths. The triangular-wave voltametric scan also was found to be a useful method in monitoring for signs of deteri- oration of the plating bath. 7248-Final iii ACKNOWLEDGMENT The authors wish to aclcnowledge the support given by Jimmie Brower in the preparation of the large number of test solutions. 7 248- F ina 1 V s CONTENTS 1.

  • Block Elements?
    Chapter 10 S -BLOCK ELEMENTS Question and answers carrying 1 mark 1. What are s- block elements? s-block elements are those in which the last electron enters the outermost s-orbital . As the s-orbital can accommodate only two electrons, two groups (1 & 2) belong to the s-block of the Periodic Table. 2. Name the elements present in the 1 st Group of the Periodic Table lithium, sodium, potassium, rubidium, caesium and francium. They are collectively known as the alkali metals . 3. Why I group elements are called alkali metals ? These are called so because they form hydroxides on reaction with water which are strongly alkaline in nature. 4. Name the elements present in the 2 nd Group of the Periodic Table: beryllium, magnesium, calcium, strontium, barium and radium. These elements with the exception of beryllium are commonly known as the alkaline earth metals . 5. Why II group elements are called alkaline earth metals ? These are called so because their oxides and hydroxides are alkaline in nature and these metal oxides are found in the earth’s crust. 6. What is the reason for the diagonal relationship ? Diagonal relationship is due to the similarity in ionic sizes and /or charge/radius ratio of the elements. 7. Which is smaller in size between a metal ion and its parent atom? The monovalent ions (M +) are smaller than the parent atom. 8. Which group elements show very low ionization enthalpy in the periodic table? First group elements (alkali metals) 9. How the ionization enthalpy varies in alkali metals Ionization enthalpy decrease down the group from Li to Cs.

  • Group 2 Organometallic Chemistry
    GROUP 2 ORGANOMETALLIC CHEMISTRY: AN EXCURSION INTO THE CHEMISTRY OF HIGHLY REACTIVE ORGANOBERYLLIUM COMPLEXES by ROBERT JERARD GILLIARD, JR. (Under the direction of Gregory H. Robinson) ABSTRACT The syntheses and molecular structures of N-heterocyclic carbene-stabilized derivatives 1 1 i 1 2 of BeCl2 ([L :BeCl2] (1); L : = :C{N(2, 6- Pr2C6H3)CH}2), [L :BeCl2·THF] (2), ([L :BeCl2·THF] 2 1 1 (3); L : = :C{N(2, 4, 6-Me3C6H2)CH}2, [L :BeCl2]2·dioxane (4)) and Be(BH4)2 ([L :Be(BH4)2] (5)), are described herein. The reaction of lithium borohydride with 1 afforded carbene-stabilized beryllium borohydride, (5). Notably, compound 5 is the first structurally characterized compound containing the highly reactive Be(BH4)2 monomer. Structural analysis of 5 reveals a five-coordinate beryllium atom with distorted square pyramidal geometry. To probe the reactivity of 5, it was combined with a well-known reducing agent, disodium tetracarbonylferrate [Na2Fe(CO)4·dioxane]. The addition of one equivalent of Na2Fe(CO)4·dioxane to a toluene solution of 5 yielded a dually reduced compound containing a BH2 unit, (6). The BH2 fragment is stabilized by an N-heterocyclic carbene ligand and a reduced N-heterocyclic carbene moiety. The isolation of 6 represents the first example of the “dual reduction” of both the C=C carbene backbone (hydroboration) and the C2 carbene center (hydrogenation) of an N-heterocyclic carbene ligand. In comparison to carbene-complexed beryllium chlorides, the chemistry of electron-rich silicon compounds with beryllium chloride is also presented. The reaction of carbene-stabilized 1 1 1 i disilicon, L :Si=Si:L [L : = :C{N(2, 6- Pr2C6H3)CH}2], with BeCl2 in hexane quantitatively 1 1 yields [L :Si=Si:L ]BeCl2, (7).
