  • 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.

  • Manufacturing of Potassium Permanganate Kmno4  This Is the Most Important and Well Known Salt of Permanganic Acid
    Manufacturing of Potassium Permanganate KMnO4 This is the most important and well known salt of permanganic acid. It is prepared from the pyrolusite ore. It is prepared by fusing pyrolusite ore either with KOH or K2CO3 in presence of atmospheric oxygen or any other oxidising agent such as KNO3. The mass turns green with the formation of potassium manganate, K2MnO4. 2MnO2 + 4KOH + O2 →2K2MnO4 + 2H2O 2MnO2 + 2K2CO3 + O2 →2K2MnO4 + 2CO2 The fused mass is extracted with water. The solution is now treated with a current of chlorine or ozone or carbon dioxide to convert manganate into permanganate. 2K2MnO4 + Cl2 → 2KMnO4 + 2KCl 2K2MnO4 + H2O + O3 → 2KMnO4 + 2KOH + O2 3K2MnO4 + 2CO2 → 2KMnO4 + MnO2 + 2K2CO3 Now-a-days, the conversion is done electrolytically. It is electrolysed between iron cathode and nickel anode. Dilute alkali solution is taken in the cathodic compartment and potassium manganate solution is taken in the anodic compartment. Both the compartments are separated by a diaphragm. On passing current, the oxygen evolved at anode oxidises manganate into permanganate. At anode: 2K2MnO4 + H2O + O → 2KMnO4 + 2KOH 2- - - MnO4 → MnO4 + e + - At cathode: 2H + 2e → H2 Properties: It is purple coloured crystalline compound. It is fairly soluble in water. When heated alone or with an alkali, it decomposes evolving oxygen. 2KMnO4 → K2MnO4 + MnO2 + O2 4KMnO4 + 4KOH → 4K2MnO4 + 2H2O + O2 On treatment with conc. H2SO4, it forms manganese heptoxide via permanganyl sulphate which decomposes explosively on heating. 2KMnO4+3H2SO4 → 2KHSO4 + (MnO3)2SO4 + 2H2O (MnO3)2SO4 + H2O → Mn2O7 + H2SO4 Mn2O7 → 2MnO2 + 3/2O2 Potassium permanganate is a powerful oxidising agent. A mixture of sulphur, charcoal and KMnO4 forms an explosive powder.

  • Perkin's Mauve: the History of the Chemistry
    REFLECTIONS Perkin’s Mauve: The History of the Chemistry Andrew Filarowski Those of us who owe our living in part to the global dyestuff and chemical industry should pause today and remember the beginnings of this giant industry which started 150 years ago today with William Perkins’ discovery of mauveine whilst working in his home laboratory during the Easter holiday on April 28, 1856. Prior to this discovery, all textiles were dyed with natural dyestuffs and pigments. What did Perkin’s Reaction Entail? William Henry Perkin carried out his experiments at his home laboratory in the Easter break of 1856. He was trying to produce quinine (C20H24N2O2). This formula was known but not the structural formula. Because chemistry was in such an early stage of development Perkin thought that by simply balancing the masses (simple additive and subtractive chemistry) in an equation he would obtain the required compound. He therefore believed that if he took two allyltoluidine molecules, C10H13N, and oxidised them with three oxygen atoms (using potassium dichromate) he would get quinine (C20H24N2O2) and water. 2 (C10H13N) + 3O C20H24N2O2 + H2O It is unsurprising to us now but Perkin reported “that no quinine was formed, but only a dirty reddish brown precipitate.” However, he continued in his trials and decided to use aniline (C6H5NH2) and its sulphate, and to oxidise them using potassium dichromate. This produced a black precipitate that Perkin at first took to be a failed experiment, but he noticed on cleaning his equipment with alcohol that a coloured solution was obtained. Perkin’s Patent W H Perkin filed his patent on the 26th August 1856 for “Producing a new colouring matter for the dyeing with a lilac or purple color stuffs of silk, cotton, wool, or other materials.” (sic) Patent No.

  • Experiment 14: a Kinetic Study of the "Breathalyzer" Reaction
    1 Experiment 14: A Kinetic Study of the "Breathalyzer" Reaction Objective: In this experiment, you will study the kinetics of the reaction of ethanol and acidic potassium dichromate to determine whether the reaction is zero, first or second order with respect to dichromate concentration and to determine the rate constant of the reaction. Introduction In the 1960's, as concern over the increasing number of injuries and fatalities caused by drunken drivers began to rise, chemists looked toward the development of simple screening tests that could be used by police officers to determine the level of alcohol in the blood of a car operator. Drinking alcohol, referred to by chemists as ethanol, has the following chemical structure: H H H C C O H H H It can react with a variety of oxidizing agents to produce the compound acetaldehyde, which has the structure shown: H O H C C H H One oxidizing agent that will accomplish this transformation is potassium dichromate, K2Cr2O7. (See Tro, pp 1004-1008, for further discussion regarding alcohols and aldehydes.) Potassium dichromate produces a yellow solution when dissolved in acid. As an acidic solution of dichromate reacts with ethanol, the Cr(VI) species is reduced to a Cr(III) species, which is green in aqueous solution. The overall reaction is as follows: 2– + 3+ 3 CH3CH2OH + Cr2O7 + 8 H → 3 CH3C(O)H + 2 Cr + 7 H2O (1) yellow green Because the reaction is accompanied by this dramatic color change, it is possible to monitor it spectrophotometrically. In a “Breathalyzer”, a portable instrument used by the police to test alcohol levels in the blood, the breath is passed through an ampoule that contains an aqueous solution of K2Cr2O7 and sulfuric acid.
