    AN ABSTRACT OF THE THESIS OF JOHN ARTHUR HAUSCHILD for the MASTER OF SCIENCE (Name) (Degree) in CHEMISTRY (ANALYTICAL) presented on (Major) Title: CHROMATOGRAPHIC SEPARATION OF ALKALINE EARTH METALS USING ALPHA-HYDROXYISOBUYRIC ACID Abstract approved: Redacted for Privacy Max B. Williams A systematic study of the elution of magnesium and calcium from Dowex 50 X 8 resin using a-hydroxyisobutyric acid (a-HIBA) at various pH values and concentrations, indicated that the difference in the equilibrium distribution coefficients of these two elements was large enough for a good separation.This fact was applied to develop a chromatographic procedure for the separationof milligram quantities of magnesium, calcium, strontium, and barium.After magnesium was eluted with 0. 22M a-HIBA at pH 4. 5, thethree remaining elements were eluted by varying the concentration and pH of a-HIBAduring the course of the elution (exponential gradient elution).After its respec- tive elution, each alkaline earth metal was directly determined by atomic absorption spectroscopy.Using this method, several success- ful analyses of synthetic samples (similar to the composition of sea water) were performed.Yield determinations of the alkaline earth metals from these analyses were consistently greater than 93%, with the overall average yield being 98%.

The information on the summary is basic information and is not intended to provide emergency response information, medical information or treatment information. The summary should not be used to provide in-depth safety and health information. In-depth safety and health information can be found in the Safety Data Sheet (SDS) for the chemical substance. Names • Ammonium bifluoride (ABF) • Ammonium difluoride • Ammonium acid fluoride • Ammonium hydrogen difluoride • Ammonium fluoride compound with hydrogen fluoride (1:1) Product Overview Solvay Fluorides, LLC does not sell ammonium bifluoride directly to consumers. Ammonium bifluoride is used in industrial applications and in other processes where workplace exposures can occur. Ammonium bifluoride (ABF) is used for cleaning and etching of metals before they are further processed. It is used as an oil well acidifier and in the etching of glass or cleaning of brick and ceramics. It may also be used for pH adjustment in industrial textile processing or laundries. ABF is available as a solid or liquid solution (in water). Ammonium bifluoride is a corrosive chemical and contact can severely irritate and burn the skin and eyes causing possible permanent eye damage. Breathing ammonium bifluoride can severely irritate and burn the nose, throat, and lungs, causing nosebleeds, cough, wheezing and shortness of breath. On contact with water or moist skin, ABF can release hydrofluoric acid, a very dangerous acid. Inhalation or ingestion of large amounts of ammonium bifluoride can cause nausea, vomiting and loss of appetite.

It also is found in many sewer gases. It is a by-product of many industrial processes. Trace amounts of dis- solved H2S are found in wastewaters in equilibrium with dissolved sulfides and hydrosulfides. It also is found in volcanic eruptions, hot springs and in troposphere. The average concentration of H2S in the air is about 0.05 ppb. The most important applications of hydrogen sulfide involve the production of sodium sulfide and other inorganic sulfides. Hydrogen sulfide obtained as a by-product often is converted into sulfuric acid. It also is used in organic syn- thesis to make thiols or mercaptans. Other applications are in metallurgy for extracting nickel, copper, and cobalt as sulfides from their minerals; and in classical qualitative analytical methods for precipitation of many metals (see Reactions). It also is used in producing heavy water for nuclear reactors. Physical Properties Colorless gas; characteristic odor of rotten eggs; odor threshold 1ppm; sweetish taste; fumes in air; flammable gas, burns with a pale blue flame; refractive index at 589.3nm, 1.000644 at 0°C and 1 atm; density 1.539 g/L at 0°C; critical temperature 100.4°C; critical pressure 88.9 atm; liquefies at –60.7°C; solidifies at –85.5°C; velocity of sound 289 m/sec in H2S gas; slightly soluble in water (0.4% at 20°C); pH of a saturated aqueous solution 4.5; slight- ly acidic; diffusivity in water at 16°C, 1.77x105 cm2/sec; soluble in carbon disulfide, methanol, acetone; very soluble in N-methylpyrrolidinone and alka- nolamines (salt formation occurs: salt dissociates on heating); liquid H2S dis- solves sulfur and SO2.

    Mechanochemical Catalytic Transfer Hydrogenation of Aromatic Nitro Derivatives

    Article Mechanochemical Catalytic Transfer Hydrogenation of Aromatic Nitro Derivatives Tomislav Portada, Davor Margetić and Vjekoslav Štrukil * Division of Organic Chemistry and Biochemistry, Ruđer Bošković Institute, Bijenička cesta 54, 10000 Zagreb, Croatia; [email protected] (T.P.); [email protected] (D.M.) * Correspondence: [email protected]; Tel.: +385‐1‐468‐0197 Received: 15 November 2018; Accepted: 29 November 2018; Published: date Abstract: Mechanochemical ball milling catalytic transfer hydrogenation (CTH) of aromatic nitro compounds using readily available and cheap ammonium formate as the hydrogen source is demonstrated as a simple, facile and clean approach for the synthesis of substituted anilines and selected pharmaceutically relevant compounds. The scope of mechanochemical CTH is broad, as the reduction conditions tolerate various functionalities, for example nitro, amino, hydroxy, carbonyl, amide, urea, amino acid and heterocyclic. The presented methodology was also successfully integrated with other types of chemical reactions previously carried out mechanochemically, such as amide bond formation by coupling amines with acyl chlorides or anhydrides and click‐type coupling reactions between amines and iso(thio)cyanates. In this way, we showed that active pharmaceutical ingredients Procainamide and Paracetamol could be synthesized from the respective nitro‐precursors on milligram and gram scale in excellent isolated yields. Keywords: mechanochemistry; catalytic transfer hydrogenation; aromatic nitro derivatives; ammonium formate; aging; ball milling; synthesis 1. Introduction Catalytic hydrogenation is one of the most significant functional group transformation reactions in organic synthesis and numerous procedures and reagents have been developed for that purpose [1,2]. As such, the hydrogenation reaction plays one of the key roles in many industrially important processes, for example hydrogenation of carbon monoxide to methanol or in food industry for the conversion of unsaturated vegetable oils into saturated triglycerides [3].

    Chem. Anal. (Warsaw), 38, 639 (1993) Gravimetric Determination of Vanadium as V(IV)-Oxinate by S. Kaur, A. K. Chhakkarand L. R. Kakkar* Department ofChemistry, Kurukshetra University, Kurukshetra -132119, Haryana; India Key words: vanadium(V), oxine, 8-hydroxyquinoline, gravimetry A very simple gravimetric method for the determination of vanadium has been worked out. In acid medium vanadium is reduced to tetravalent state which forms greenish-black precipitate with 8-hydroxyquinoline (2 % in 2 mol 1-1 CH3COOH) in the presence of ammonium acetate. The precipitate is dried and weighedas VO(C9H60 N)2. The con­ version factor for vanadium is 0.1437. The method is free from the interference of molybdenum(VI), chromium(III,VI), uranium(VI), selenium(IV), arsenic(I1I), bis­ muth(III), lead(U), calcium(II), manganese(I1) and maguesium(II).

Cup ferron [4b] is generally recommended for the precipitation of vanadium, but several precautions are necessary because ofthe instability of cupfer­ ron and many other elements are precipitated by the reagent under conditions ofthe * Senior author for correspondence.
