Quantification of Lithium Via Redox Titration and Ph Titration – a Method Comparison
Quantification of Lithium via Redox Titration and pH Titration – A Method Comparison by Joseph J. 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. -
Salts in Organic Synthesis: an Overview and Their Diversified Use
Salts in Organic Synthesis: an overview and their diversified use Dirgha Raj Joshi1* and Nisha Adhikari2 1. College of Pharmacy, Yonsei University International Campus, Incheon, Republic of Korea 2. College of Pharmacy, Gachon University Medical Campus, Incheon, Republic of Korea *Correspondence: Dirgha Raj Joshi Email:[email protected], [email protected] ORCID ID: 0000-0002-0303-5677 Abstract The chemistry of salt is of great importance due to its immense potential from the daily life use to the synthetic chemistry like as workup material, as reagents, as phase transfer catalyst, as acid, as base, as catalyst, as agents for asymmetric synthesis, for some specific reaction transformation, to increase yield, decrease reaction time, ecofriendly synthesis, handling easiness and many more. This review summarizes the basic background of salts, its application, synthesis of new salts, and list of individual categories of major commercially available salts with some structure. Keywords: Organic synthesis, green chemistry, salts, catalyst, reagent, asymmetric synthesis, acid, base Introduction In chemistry, the salt is usually a solid chemical compound having related numbers of positively charged ions called cation and negatively charged ions called anions which are assembled to form a solid mass, so the whole mass is electrically neutral 2- (no net charge). These ions particle can be either organic (acetate- CH3CO ) or inorganic (chloride- Cl-, fluoride- F- etc.) and can be as a monoatomic (chloride- - 2- Cl ) or polyatomic (sulfate- SO 4)[1]. For organic synthesis, the considerations about various factors play a crucial role. With this respect, the organic and inorganic salts always remain core corner in the reagents category. -

H2TPP Organocatalysis in Mild and Highly Regioselective Ring Opening of Epoxides to Halo Alcohols by Means of Halogen Elements

Received: 10 January 2012; in revised form: 6 April 2012 / Accepted: 12 April 2012 / Published: 9 May 2012 Abstract: We found that elemental iodine and bromine are converted to trihalide nucleophiles (triiodine and tribromide anion, respectively) in the presence of catalytic amounts of meso-tetraphenylporphyrins (H2TPP). Therefore a highly regioselective method for the synthesis of -haloalcohols through direct ring opening of epoxides with elemental iodine and bromine in the presence of H2TPPs as new catalysts is described. At room temperature a series of epoxide derivatives were converted into the corresponding halohydrins resulting from an attack of trihalide species anion atoms at the less substituted carbon atom. This method occurs under neutral and mild conditions with high yields in various aprotic solvents, even when sensitive functional groups are present. Keywords: oxirane; ring opening; nucleophilic addition; elemental halogen; meso-tetraarylporphyrine; halohydrine 1. Introduction Oxiranes are among the most versatile intermediates in organic synthesis, as they can be easily prepared from a variety of other functional groups [1] and due to their ring strain and high reactivity, their reactions with various nucleophiles lead to highly regio and stereoselective ring opened products [2–4]. -
