Bimetallic Catalyst Catalyzed Carbonylation of Methanol to Acetic Acid
materials Article Study on Rh(I)/Ru(III) Bimetallic Catalyst Catalyzed Carbonylation of Methanol to Acetic Acid Shasha Zhang 1, Wenxin Ji 1,2,*, Ning Feng 2, Liping Lan 1, Yuanyuan Li 1,2 and Yulong Ma 1,2 1 College of Chemistry and Chemical Engineering, Ningxia University, Yinchuan 750021, China; [email protected] (S.Z.); [email protected] (L.L.); [email protected] (Y.L.); [email protected] (Y.M.) 2 State Key Laboratory of High-efficiency Utilization of Coal and Green Chemical Engineering, Ningxia University, Yinchuan 750021, China; [email protected] * Correspondence: [email protected]; Tel.: +86-135-1957-9989; Fax: +86-951-206-2323 Received: 13 July 2020; Accepted: 3 September 2020; Published: 11 September 2020 Abstract: In this study, a Rh(I)/Ru(III) catalyst with a bimetallic space structure was designed and synthesized. The interaction between the metals of the bimetallic catalyst and the structure of the bridged dimer can effectively reduce the steric hindrance effect and help speed up the reaction rate while ensuring the stability of the catalyst. X-ray photoelectron spectroscopy (XPS) results show that rhodium accepts electrons from chlorine, thereby increasing the electron-rich nature of rhodium and improving the catalytic activity. This promotes the nucleophilic reaction of the catalyst with methyl iodide and reduces the reaction energy barrier. The methanol carbonylation performance of the Rh/Ru catalyst was evaluated, and the results show that the conversion rate of methyl acetate and the yield of acetic acid are 96.0% under certain conditions. Furthermore, during the catalysis, no precipitate is formed and the amount of water is greatly reduced.

1 the Volumetric Determination of Hydroxylamine
VOLUMETRIC DETERMINATION OF HYDROXYLAMINE. I363 [CONTRIBUTION FROM THE CHEMICAL LABORATORYOF THE UNIVERSITY OF CALIFORNIA.1 THE VOLUMETRIC DETERMINATION OF HYDROXYLAMINE. BY WILLIAMC. BRAY,MIBUM E. SIMPSONAND ANNA A. MACKENZIE. Received July 17, 1919 In the present investigation 3 volumetric methods of determining hydroxylamine in aqueous solution have been studied : The titanous salt method,' in which the hydroxylamine is reduced by excess titanous salt in acid solution with exclusion of air, and the excess titrated with permanganate. 2NH20H + Ti2(S04)3 = (NH4)2S04 + 4TiOS04 + HzS04. (I) The ferric salt method,2 in which the hydroxylamine is oxidized in an acid solution by excess of a ferric salt, the mixture is boiled and the fer- rous salt formed titrated with permanganate. 2NH20H + 2Fe@04)3 = N2O + 4FeS04 + 2H2S04 + H20. (2) The iodine method,3 in which the hydroxylamine is oxidized by iodine in a neutral solution, e. g., in the presence of disodium phosphate. 2NH20H + 212 = N2O + 4HI + H2O (3) or 2NH20H + 213- = N20 + 61- + 4H+ + HzO. Our first experiments, with the iodine method, yielded irregular results which could not be interpreted until the concentration of the hydroxyl- amine solution was accurately determined. An examination of the literature showed a rather unsatisfactory state of affairs. The advocates of the ferric sulfate method furnish evidence that it is perfectly reliable, but Leuba4 gives detailed experimental data to prove the contrary, and Adams5 states that he could not obtain reproducible results with it. The investigators who have used the iodine method consider it to be fairly satisfactory, but some of them state that it is not very accurate, and Rupp and Maeder6 have recently concluded that correct results are obtained only by a compensation of errors.

A Fundamental Evaluation of the Atmospheric Pre-Leaching Section of the Nickel-Copper Matte Treatment Process
A FUNDAMENTAL EVALUATION OF THE ATMOSPHERIC PRE-LEACHING SECTION OF THE NICKEL-COPPER MATTE TREATMENT PROCESS by RODRICK MULENGA LAMYA Dissertation presented for the Degree of DOCTOR OF PHILOSOPHY (Extractive Metallurgical Engineering) in the Department of Process Engineering at the University of Stellenbosch, South Africa Promoter Prof. L. Lorenzen STELLENBOSCH March 2007 DECLARATION I the undersigned, hereby declare that the work contained in this dissertation is my own original work and that I have not previously in its entirety or in part submitted it at any university for a degree. Signature: ............................................... Date: ....................................................... Copyright © 2007 Stellenbosch University All rights reserved i SYNOPSIS Nickel-Copper sulphide ores are the most important Platinum Group Metal bearing ores. The South African deposits are exceptionally rich in the platinum group metals (PGMs) and production of the PGMs is the primary purpose of treating these ores. The methods used in the recovery of the PGMs from the nickel-copper ores generally consists of ore concentration by physical techniques, pyrometallurgical concentration and hydrometallurgical extraction of the base metals followed by the PGMs. Pyrometallurgical concentration produces Ni-Cu matte, which is treated by hydrometallurgical processes to recover the nickel, copper, cobalt and the precious metals. In this study, the leaching behaviour of a Ni–Cu matte in CuSO4–H2SO4 solution during the repulping (pre-leach) stage at Impala Platinum Refineries was studied. The repulping stage is basically a non–oxidative atmospheric leach stage, in which nickel, iron and cobalt are partially dissolved, while the copper is precipitated. To understand the nature of the leaching process during this stage of the base metal refining operation, the effects of variations in the key process variables such as temperature, stirring rate, particle size, pulp density, residence time, initial copper and acid concentrations were investigated.

Cyanide Remediation: Current and Past Technologies C.A
CYANIDE REMEDIATION: CURRENT AND PAST TECHNOLOGIES C.A. Young§ and T.S. Jordan, Department of Metallurgical Engineering, Montana Tech, Butte, MT 59701 ABSTRACT Cyanide (CN-) is a toxic species that is found predominantly in industrial effluents generated by metallurgical operations. Cyanide's strong affinity for metals makes it favorable as an agent for metal finishing and treatment and as a lixivant for metal leaching, particularly gold. These technologies are environmentally sound but require safeguards to prevent accidental spills from contaminating soils as well as surface and ground waters. Various methods of cyanide remediation by separation and oxidation are therefore reviewed. Reaction mechanisms are given throughout. The methods are compared in regard to their effectiveness in treating various cyanide species: free cyanide, thiocyanate, weak-acid dissociables and strong-acid dissociables. KEY WORDS cyanide, metal-cyanide complex, thiocyanate, oxidation, separation INTRODUCTION ent on the transport of these heavy metals through their tissues, cyanide is very toxic.

Combining Sodium Bicarbonate and Lidocaine Injection
Combining Sodium Bicarbonate and Lidocaine injection Tom Simpleman Consultant Pharmacist the FAWKS company http://dailymed.nlm.nih.gov/dailymed/lookup.cfm?setid=f9c826a7‐8f19‐4857‐b5be‐11dcafcfc7a9 Referenced information from National Institutes of Health DESCRIPTION: Sodium Bicarbonate Inj., 8.4% USP Neutralizing Additive Solution is a sterile, nonpyrogenic, solution of sodium bicarbonate (NaHCO3) in Water for Injection. It is added to an appropriate local anesthetic as a neutralizing agent immediately prior to administration. The solution contains no bacteriostat, antimicrobial agent or added buffer and is intended only for single-use. pH is adjusted with carbon dioxide. Per the USP monograph for Sodium Bicarbonate Inj., pH is between 7.0 and 8.5. Osmolar concentration is 2 mOsmol/mL (calc.). Sodium bicarbonate, 84 mg is equal to one milliequivalent each of Na+ and HCO3-. Sodium Bicarbonate, USP is chemically designated as NaHC03, a white crystalline powder soluble in water. Sodium bicarbonate in water dissociates to provide sodium (Na+) and bicarbonate (HCO3-) ions. Sodium (Na+) is the principal cation of the extracellular fluid and plays a large part in the therapy of fluid and electrolyte disturbances. Bicarbonate (HCO3-) is a normal constituent of body fluids and the normal plasma level ranges from 24 to 31 mEq/liter. Bicarbonate anion is considered “labile” since at a proper concentration of hydrogen ion (H+) it may be converted to carbonic acid (H2CO3) and thence to its volatile form, carbon dioxide (CO2) excreted by the lung. Normally a ratio of 1:20 (carbonic acid; bicarbonate) is present in the extracellular fluid. In a healthy adult with normal kidney function, practically all the glomerular filtered bicarbonate ion is reabsorbed; less than 1% is excreted in the urine.
