Use descriptors are adapted from ECHA guidance to improve readability and may not correspond textually to descriptor codes described in Chapter R.12: Use Descriptor system of ECHA Guidance on information requirements and chemical safety assessment. Release to the environment of this substance can occur from industrial use: manufacturing of the substance. These notifications can be provided by manufacturers, importers and downstream users. Other reasons for its loss of popularity were its dirty-black color, dusty appearance and irritating properties, as well as its inhibition of an alcohol-degrading enzyme which causes temporary accumulation of acetaldehyde in the body leading to dizziness, nausea and hot flashes when alcohol is consumed around the time of bodily exposure. This substance is used in the following products: fertilisers. The POPs Regulation bans or severely restricts the production and use of persistent organic pollutants in the European Union. Common Name. It applies the European Agreements on the international transport of dangerous goods by road (ADR) and inland waterways (ADN), and the Regulations concerning the international carriage of dangerous goods by rail (RID). Calcium cyanamide is the inorganic compound with the formula CaCN2. Deutsches Reichspatent DRP 88363, "Verfahren zur Darstellung von Cyanverbindungen aus Carbiden", Erfinder: A. Frank, N.

It is the responsibility of the substance manufacturers and importers to consult official publications, e.g. ECHA has no public registered data on the routes by which this substance is most likely to be released to the environment. ECHA maintains the C&L Inventory, but does not review or verify the accuracy of the information. Calcium cyanamide is harmful and should be handled with care. The process was particularly challenging due to the equipment requirements required by the high temperatures during the initial igniter step. Calcium cyanamide is prepared from calcium carbide. Dangerous Goods List (ADR, Chap. [9] It was at the time the cheapest nitrogen fertilizer with additional efficacy against weeds and plant pests and had great advantages over conventional nitrogen fertilizers. Harmonisation is based on the substance’s physical, toxicological and eco-toxicological hazard assessment. Buying Leads | The main use of calcium cyanamide is in agriculture as a fertilizer. This directive requires employers to ensure proper signage is posted in areas where hazards cannot be avoided or reduced. It was first synthesized in 1898 by Adolph Frank and Nikodem Caro (Frank-Caro process). (5) Commercial grades of calcium cyanamide occur as grayish-black lumps of powder. Calcium cyanamide must be kept in closed containers, away from moisture. This database contains the ADN's Dangerous Goods List, as implemented by the EU's Directive 2008/68/EC.

Calcium cyanamide is a white (gray or black if impure) solid, which reacts with water. The CAS number is the substance numerical identifier assigned by the Chemical Abstracts Service, a division of the American Chemical Society, to substances registered in the CAS registry database. [14], Cyanamide calcium salt, Lime Nitrogen, UN 1403, Nitrolime, Except where otherwise noted, data are given for materials in their. 52 0 obj <>stream It is also used as an alcohol-deterrent drug in Canada, Europe, and Japan. 46; (1924); p. 1358 - 1366, Franklin; Journal of the American Chemical Society; vol. The advantage of lowering the reaction temperature by about 400 °C, however, must be weighed against the high amount of calcium chloride required and the discontinuous process control. Other reasons for its loss of popularity were its dirty-black color, dusty appearance and irritating properties, as well as its inhibition of an alcohol-degrading enzyme which causes temporary accumulation of acetaldehyde in the body leading to dizziness, nausea and hot flashes when alcohol is consumed around the time of bodily exposure.
