Because this group is the functional group of aldehydes, ketones, and carboxylic acids and their derivatives, it is one of the most important functional groups in organic chemistry and in the chemistry of biological systems. The chemical properties of the carbonyl group are straightforward, and an understanding of its characteristic reaction themes leads very quickly to an understanding of a wide variety of organic reactions.

Hebert A THESIS submitted to Oregon State University Honors College in partial fulfillment of the requirements for the degree of Honors Baccalaureate of Science in Chemical Engineering and Chemistry (Honors Associate) Presented May 26, 2020 Commencement June 2020 AN ABSTRACT OF THE THESIS OF Joseph J. Hebert for the degree of Honors Baccalaureate of Science in Chemical Engineering and Chemistry presented on May 26, 2020. Title: Quantification of Lithium via Redox Titration and pH Titration - A Method Comparison. Abstract approved:_____________________________________________________ Michael Lerner Lithium serves an unparalleled role for high energy-density storage applications and is vital for the continued advancement of the world economy. However, global supply is heavily reliant on lithium deposits situated in select locations, creating unpredictability in the price and concerns for the sustained production of the resource. Additionally, future demands for applications in the small electronics, automotive, and renewable energy industries threaten to place further strain on the lithium supply. Thus, the implementation of lithium battery recycling methods is critical meet this expected surge in demand for lithium-based battery technologies. Several economic obstacles and safety considerations have halted the advancement of these necessary recycling techniques. A prominent barrier to recycling efforts revolves around the reactivity of active lithium compounds that remain in used lithium batteries. As a result, significant safety precautions must be taken when handling and transporting lithium-based batteries, adding to the costs associated with recycling methods. Current research has been dedicated to developing a passivation method for the remaining active lithium in used cells, seeking to lower the classification, and subsequently the costs, associated with these materials.

Rosamilia1, Maurizio Rigo1, Andrea Maranzana1,3, and Glauco Tonachini3 1Interuniversity Consortium “Chemistry for the Environment”, Via delle Industrie, 21/8 30175 Marghera, Venice, Italy; 2Department of Environmental Sciences, Ca’ Foscari University of Venice, Dorsoduro 2137-30123, Venice, Italy; 3Department of General Chemistry and Organic Chemistry, University of Torino, Corso Massimo D’Azeglio 48, I-10125 Torino, Italy Abstract: A series of dialkyl and methyl alkyl carbonates has been synthesized and their re- activity investigated. The behavior of preferential leaving and entering groups for the newly synthesized carbonates has been accurately investigated. Both experimental and computa- – – ≥ tional studies agreed that the scale of leaving groups follows the trend: PhCH2O , MeO – – – – – EtO , CH3(CH2)2O , CH3(CH2)7O > (CH3)2CHO > (CH3)3CO . Accordingly, the scale of the entering group has the same trend, with t-butoxide being the worst entering group. A preliminary attempt to rationalize the nucleofugality trends, lim- – – ited to the (CH3)3CO and CH3O groups, has indicated that a likely origin of the observed trends lies in the different entropic contributions and solvation effects. Keywords: computational studies; dimethyl carbonate; green chemistry; synthesis; theoreti- cal chemistry. INTRODUCTION Since the 1980s, when dimethyl carbonate (DMC) was synthesized for the first time using a green process [1], its exploitation both in industrial [2] and laboratory scale [3] has grown exponentially.

    How to Use This Guide Dielectric Constant Table

    Dielectric Constant Table.xls Dielectric Constant Table Dielectric Constant (k) is a number relating the ability of a material to carry alternating current to the ability of vacuum to carry alternating current. The capacitance created by the presence of the material is directly related to the Dielectric Constant of the material. Alphabetic Table A B C D Knowing the Dielectric Constant (k) of a material is needed to properly E F G H design and apply instruments such as level controls using radar, RF I J K L admittance, or capacitance technologies. There are also analytical M N O P reasons to know the (k) of a material. Q R S T U V W X How to use this guide Y Z # CLIPPER CONTROLS has compiled an extensive list of products with Dielectric Constants. Many of these Dielectric Constants are given at specific temperatures. If your product's temperature is significantly different from those listed there is a good chance that the Dielectric Constant may be different from the values listed. The products in this reference are listed in alphabetical order and are grouped in sections by the first letter of their name.

    Acroseal Packaging Your Solution for Air- and Moisture- Sensitive Reagents

    AcroSeal Packaging Your solution for air- and moisture- sensitive reagents Extra dry solvents Deuterated solvents Organometallic compounds Reagents in solution Organics Introduction Since the launch of AcroSealTM packaging we have introduced a new septum, which helps preserve product quality for longer. In addition, our AcroSeal portfolio has been expanded to include a broad range of solvents, organometallics, reagents in solution and organic compounds. In this brochure we have categorized our products under chemical families to make it easier to locate the product you need. Introduction Page no.

Through the innovative quadrant-style screw cap and specially designed septum, AcroSeal packaging ensures that you have access to high-quality and low-moisture products every use, guaranteeing improved yield and consistency of your research experiments while reducing chemical waste. AcroSeal packaging highlights New septum developed from a polymeric elastomer with an inert fluoropolymer-coated surface, preserves product quality for longer with better re-seal around needle punctures.

Received: 16 October 2017; Accepted: 29 November 2017; Published: 30 November 2017 Abstract: Carbonate-type macrodiols synthesized by base-catalyzed polycondensation of co-diols and dimethyl carbonate as an environmentally-friendly route were subsequently utilized for the preparation of transparent and self-healable thermoplastic polyurethanes (TPUs) containing a carbonate-type soft segment. Three types of macrodiols, obtained from mono, dual and triple diol-monomers for target molecular weights of 1 and 1.5 kg mol−1, were analyzed by 1H NMR integration and the OH titration value.
