Abstract Medications that inhibit aldehyde dehydrogenase when coadministered with alcohol produce accumulation of acetaldehyde. Acetaldehyde toxic effects are characterized by facial flushing, nausea, vomiting, tachycardia and hypotension, symptoms known as acetaldehyde syndrome, disulfiram-like reactions or antabuse effects. Severe and even fatal outcomes are reported. Besides the aversive drugs used in alcohol dependence disulfiram and cyanamide (carbimide), several other pharmaceutical agents are known to produce alcohol intolerance, such as certain anti-infectives, as cephalosporins, nitroimidazoles and furazolidone, dermatological preparations, as tacrolimus and pimecrolimus, as well as chlorpropamide and nilutamide. The reactions are also observed in some individuals after the simultaneous use of products containing alcohol and disulfiram-like reactions inducers.

  • 44. Heat of Combustion of Calcium Cyanamide
    No. 3.] 161 44. Heat of Combustion of Calcium Cyanamide. Naoto KAMEYAMAand Sojiro OKA. Institute of Applied Chemistry, Tokyo Imperial University. (Rec. March 8, 1927. Comm. by K. TAW1ARA,M.I.A., March 12, 1927.) How much of heat is developed when nitrogen is fixed by carbide of calcium in the form of cyanamideof calcium is a question which remains still to be solved. One of the present authors') tried to determine it calorimetrically, soon after he had succeeded to prepare calcium cyanamide ofhigh purity by the repeated calcination of calcium oxide with dicyanodiamide in current of nitrogen. The cyanamide burns in oxygen quantitatively according to the following equation: CaCN2+3/2. 02=CaO+CO2+N, This reaction was utilized for the determination of heat of combustion of the cyanamide and the result was 1935.5 calories per gram of CaCNa, which gave the following value for the heat of formation of the cyanamide from the carbide: CaC2 + N,= CaCN.,+ Cgraphite+77.830 cal. In the Fixed Nitrogen Research Laboratory of the United States, the heat of the last named reactionwas determined directly by the nitrogenation of calcium carbide in the calorimetric bomb, and the result was 97,800 call As this value was widely different from the above mentioned, it was much desired to redetermine the heat of combustion, though it was not possible at the time to do it, because the author had been staying in Europe. Recentlythe work was resumed with improvements in many points and has lead to the result here to be presented. During the while, another workdone by Frank and Hoch- wald3' was published, and the heat of combustion was foundto be 2036 cal.

Brimble Received: 9 March 2017; Accepted: 7 April 2017; Published: 12 April 2017 Abstract: The application of alkyl and aryl substituted cyanamides in synthetic chemistry has diversified multi-fold in recent years. In this review, we discuss recent advances (since 2012) in the chemistry of cyanamides and detail their application in cycloaddition chemistry, aminocyanation reactions, as well as electrophilic cyanide-transfer agents and their unique radical and coordination chemistry. Keywords: cyanamide; synthesis; aminocyanation; cycloaddition; electrophilic cyanation; radical reaction; coordination chemistry 1. Introduction Cyanamide enjoys a rich chemical history, which can be traced to its unique and chemically promiscuous nitrogen-carbon-nitrogen (NCN) connectivity. The chemistry of the nitrile-substituted amino-group of the ‘cyanamide-moiety’ is dominated by an unusual duality of a nucleophilic sp3-amino nitrogen and an electrophilic nitrile unit. The reported use of unsubstituted cyanamide (NH2CN) and metal cyanamides (MNCN, where M = metal) date back as far as the late 19th century, where the likes of calcium cyanamide (CaNCN) was used as a fertilizer, and later as source of ammonia and nitric acid, which fueled the industrial production of metal cyanamides. In contrast, the reported use of the corresponding substituted organic cyanamides (RNHCN or RR’NCN) gathered pace only in more recent years.

  • The Mechanism of the Decomposition of Cyanamide in the Soil
    THE MECHANISM OF THE DECOMPOSITION OF CYANAMIDE IN THE SOIL. BY G. A. COWIE. (Rothamsted Experimental Station, Harpenden.) (With Five text-figures.) A PREVIOUS investigation by the writer (i) showed that cyanamide readily breaks down, yielding ammonia in normal clay and sandy soils. The evidence, however, threw no light upon the cause or nature of this change. This question was accordingly reserved for a later investigation. The concensus of the available evidence indicated that the production of ammonia from cyanamide in the soil is due to direct bacterial action. This view was held by Immendorff(2) and Kappen(3), who concluded that in poor soils of low bacterial activities cyanamide is not converted into ammonia but is chemically transformed into dicyanodiamide. L6hnis(4) at first accounted in a similar way for the formation of ammonia from cyanamide in the soil. He (5) assumed later, however, that cyana- mide is normally decomposed by soil colloids into urea or possibly some other substances, and the latter are then converted into ammonia by the soil organisms. He adduced no direct evidence of the production of urea from cyanamide in the soil. Ulpiani (6) regarded the formation of ammonia as primarily due to a purely chemical, not a bacterial, change. He had formerly considered that cyanamide changed into dicyanodiamide in the soil and its value as a fertiliser depended on this change, an opinion also held by Perotti(7). Ulpiani's later work, however, led him to the view that cyanamide breaks down by a purely chemical change to urea which then is con- verted into ammonia.

This information is distributed solely for the purpose of pre dissemination public comment under applicable information quality guidelines. It has not been formally disseminated by the Agency for Toxic Substances and Disease Registry. It does not represent and should not be construed to represent any agency determination or policy. ***DRAFT FOR PUBLIC COMMENT*** ACETONE iii FOREWORD This toxicological profile is prepared in accordance with guidelines developed by the Agency for Toxic Substances and Disease Registry (ATSDR) and the Environmental Protection Agency (EPA). The original guidelines were published in the Federal Register on April 17, 1987. Each profile will be revised and republished as necessary. The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for these toxic substances described therein. Each peer-reviewed profile identifies and reviews the key literature that describes a substance's toxicologic properties. Other pertinent literature is also presented, but is described in less detail than the key studies. The profile is not intended to be an exhaustive document; however, more comprehensive sources of specialty information are referenced. The focus of the profiles is on health and toxicologic information; therefore, each toxicological profile begins with a relevance to public health discussion which would allow a public health professional to make a real-time determination of whether the presence of a particular substance in the environment poses a potential threat to human health.

  • HPLC Analysis of Melamine and Related Substances in Fertilisers
    51 HPLC Analysis of Melamine and Related Substances in Fertilisers by Azusa Morita, Shimadzu Corporation, Japan Gesa J. Schad, Shimadzu Europa GmbH Shirai Yuji, Food and Agricultural Materials Inspection Center, Japan Calcium cyanamide is a multipurpose nitrogen fertiliser, which is also effective as a pesticide and soil amendment. It plays an important role in crop cultivation by ensuring that plants are supplied with nitrogen. Recently, high levels of melamine were discovered as a by-product in some calcium cyanamide hydrate products, pelletised by added water. Due to the risk of agricultural products absorbing melamine from soil, it has been identified as a potential public health risk. Health issues associated with melamine have been in the public eye since the Chinese milk scandal in 2008. A widely utilised precursor for many applications on the one hand, harmful contamination for feedstock and milk on the other, its use in fertiliser can also facilitate the introduction of melamine into the food chain. Long-term exposure to melamine and its related substance, cyanuric acid, through ingestion can result in bladder or kidney stones which ultimately can lead to bladder cancer [1, 2], concentration of this compound in food and feed needs to be controlled carefully.
