Test for Acetone in Urine 189 AN IMPROVED TEST FOR ACETONE IN URINE. R. E. Lyons and J. T. Brundage, Indiana University. Lieben's test for acetone 1 depends upon the formation of iodoform when potassium iodide, iodine solution, and a few drops of sodium hydroxide solution are added to an acetone containing mixture. The iodoform is recognized by its distinctive odor and, microscopically, by the 1 star, or hexagonal crystals. The test is not specific since both ethyl alcohol and acetic aldehyde also react with these reagents to yield iodo- form. This sometimes leads to erroneous results because of alcohol formed through sugar fermentation in diabetic urine. The difficulty is obviated" by substituting ammonium hydroxide for the caustic alkali as proposed by Gunning'5 in a modification of the Lieben Test. In either test the reaction is much more sensitive if a urine dis- tillate is used. The distillation not only frees the acetone from non- volatile interfering substances, but converts some acetonacetic (di-acetic) 4 acid, if present, into acetone. Protein interferes and, if present, the separation of acetone by distillation or aeration is necessary. M. KohlthofF' states that 100 mg. each of potassium iodide and chlor- amine T, 10-20 drops of 4N ammonium hydroxide and 10 cc. of a solu- tion of one part acetone in 10,000 parts of 2 per cent ethyl alcohol when warmed to 60 °C. gave an iodoform precipitate in two hours. The object of our investigation has been to determine (a) whether this reaction could be applied as a specific test for acetone in urine, (b) what urinary constituents or preservatives interfere, (c) if the necessity of distillation, or aeration, of the urine could be dispensed with, and (d) the conditions for attaining the maximum sensitiveness of the reaction. -
Laboratory 23: Properties of Aldehydes and Ketones
Laboratory 23: Properties of Aldehydes and Ketones Introduction Aldehydes and Ketones represent an important class of organic molecules containing a carbonyl carbon. In this experiment you will study the chemical properties of aldehydes and ketones. Solubility in water, and organic solvents, combustibility, and reactivity with various chemical reagents will be examined. Discussion Structure of Aldehydes and Ketones Aldehydes and Ketones are organic compounds containing a carbonyl carbon (R−C−O−R') (Figure 1 below) functional group. Carboxylic Acids and Esters also contain a carbonyl carbon, and will be explored in a future experiment. The carbonyl carbon is a polar group with the carbon having a slight excess of positive charge and the oxygen atom having a slight excess of negative charge. Chemical Properties Aldehydes and ketones are created by the mild oxidation of primary and secondary alcohols. One such method to oxidize alcohols is with copper (II) oxide. Upon heading, copper wire (Cu0) in an open flame leads to the formation of copper (II) oxide. The copper (II) oxide is then reacted with an alcohol to form an aldehyde or ketone, copper (I) oxide and water. [O] Primary Alcohol −−! Aldehyde [O] Secondary Alcohol −−! Ketone Chemically aldehydes and ketones both contain a carbonyl carbon and thus have similar chemical reactivities. However, aldehydes are more susceptible to oxidation because of the hydrogen atom attached to the carbonyl group. This is the basis for distinguishing between these two classes of compounds. Several tests are useful for differentiating between aldehydes and ketones. The first test is referred to as the Tollens' or Silver Mirror test. -

Haloform Reaction - Wikipedia
6/13/2020 Haloform reaction - Wikipedia Haloform reaction The haloform reaction is a chemical reaction where a haloform Haloform reaction (CHX , where X is a halogen) is produced by the exhaustive 3 Named after Adolf Lieben halogenation of a methyl ketone (RCOCH3, where R can be either a hydrogen atom, an alkyl or an aryl group), in the presence of a Reaction type Substitution base.[1][2][3] The reaction can be used to transform acetyl groups into reaction carboxyl groups or to produce chloroform (CHCl3), bromoform Identifiers (CHBr3), or iodoform (CHI3) and also cyanide. Organic haloform-reaction Chemistry Portal Contents Mechanism Scope Applications Laboratory scale Industrially As a by-product of water chlorination History References Mechanism In the first step, the halogen disproportionates in the presence of hydroxide to give the halide and hypohalite (example with bromine, but reaction is the same in case of chlorine and iodine; one should only substitute Br for Cl or I): If a secondary alcohol is present, it is oxidized to a ketone by the hypohalite: If a methyl ketone is present, it reacts with the hypohalite in a three-step process: 1. Under basic conditions, the ketone undergoes keto-enol tautomerization. The enolate undergoes electrophilic attack by the hypohalite (containing a halogen with a formal +1 charge). https://en.wikipedia.org/wiki/Haloform_reaction#Iodoform_reaction 1/5 6/13/2020 Haloform reaction - Wikipedia 2. When the α(alpha) position has been exhaustively halogenated, the molecule undergoes a nucleophilic − acyl substitution by hydroxide, with CX3 being the leaving group stabilized by three electron- − withdrawing groups. -
Iodoform Packing
Created by the British Columbia Provincial Nursing Skin and Wound Committee in collaboration with the Wound Clinicians from / Skin and Wound Product Information Sheet Iodoform Packing Classification Antimicrobial/Antiseptic: Iodine Key Points A ravel-resistant strip gauze packing impregnant with Iodoform, an antiseptic effective against pseudomonas. In the presence of exudate, iodoform breaks down to release Iodine (96%) and therefore should be used with caution. The packing’s colour may be opaque to yellowish and may have an oily appearance, as a small amount of oil may have been use to aid in easier removal of product from the container. Should be packed dry. Indications Use under the direction of a Physician, NP, NSWOC/Wound Clinician: o For wounds with or without undermining, sinus tract/tunnels which have signs and symptoms (S&S) of, or are at risk for, local wound infection. Precautions May cause some discomfort/pain, especially when first applied. Avoid using before and after radio-iodine diagnostic tests Make Physician/NP aware of Iodine usage for clients: o Taking lithium, as Iodine may increase the possibility of hypothyroidism when used in combination with lithium. Blood work should be monitored on a regular basis. o With renal impairment, as poor renal function is thought to be a factor in increased iodine levels in serum and urine with prolonged use and use in large wounds. o With thyroid disorders, as they are more susceptible to thyroid metabolism changes in long-term therapy. Thyroid function should be monitored if large areas are being treated for a prolonged period of time. -

Identification of an Unknown – Alcohols, Aldehydes, and Ketones
Identification of an Unknown: Alcohols, Aldehydes, and Ketones How does one determine the identity and structure of an unknown compound? This is not a trivial task. Modern x-ray and spectroscopic techniques have made the job much easier, but for some very complex molecules, identification and structure determination remains a challenge. In addition to spectroscopic information and information obtained from other instrumental methods, chemical reactions can provide useful structural information, and physical properties can contribute significantly to confirming the identity of a compound. In this experiment, you will be asked to identify an unknown liquid, which will be either an alcohol, aldehyde, or ketone. Identification will be accomplished by carrying out chemical tests, called classification tests, preparing a solid derivative of the unknown and determining its melting point (MP), making careful observations, and analyzing the NMR spectrum of the unknown. the carbonyl group O O R OH R H R R alcohol aldehyde ketone A list of alcohols, aldehydes, and ketones, along with the MP of a solid derivative of each compound, is posted on the website. The unknown will be one of these listed compounds. If one can determine to which functional group class (alcohol, aldehyde, or ketone) the unknown belongs, two of the three lists need not be considered and the task will be greatly simplified. To accomplish this, classification tests will be carried out. First, consider some general ways in which alcohols, aldehydes, and ketones react. 1 CLASSIFICATION TESTS, which are simple chemical reactions that produce color changes or form precipitates, can be used to differentiate alcohols, aldehydes, and ketones, and also to provide further structural information.
