The reaction takes several hours for completion. Frank and Caro developed this reaction for a large-scale, continuous production process. This substance is used in the following products: fertilisers. [3], Reducing calcium nitride with carbon at 800-900 °C in a nitrogen atmosphere will also give calcium cyanamide. 6(6), Reg. Release to the environment of this substance can occur from industrial use: formulation of mixtures. This white solid is widely used in agriculture and the production of pharmaceuticals and other organic compounds. ECHA has no public registered data indicating whether or into which articles the substance might have been processed. 156-62-7), https://en.wikipedia.org/w/index.php?title=Calcium_cyanamide&oldid=986623423, Chemical articles with multiple compound IDs, Multiple chemicals in an infobox that need indexing, Pages using collapsible list with both background and text-align in titlestyle, Articles containing unverified chemical infoboxes, Wikipedia articles needing clarification from February 2018, Wikipedia articles incorporating a citation from the 1911 Encyclopaedia Britannica with Wikisource reference, Creative Commons Attribution-ShareAlike License, White solid (Often gray or black from impurities), 1,150 to 1,200 °C (2,100 to 2,190 °F; 1,420 to 1,470 K) (sublimes), This page was last edited on 2 November 2020, at 00:39. 2(b)(i), Directive 98/24/EC on Protection of Workers from Chemical Agent-related Risks, 5 May 1998 (Table 3 of Annex VI to CLP, as amended), EU. It was first synthesized in 1898 by Adolph Frank and Nikodem Caro (Frank-Caro process). If generated, an InChI string will also be generated and made available for searching. 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). Deutsches Reichspatent DRP 88363, "Verfahren zur Darstellung von Cyanverbindungen aus Carbiden", Erfinder: A. Frank, N. Caro, erteilt am 31. (5) Commercial grades of calcium cyanamide occur as grayish-black lumps of powder. [4], Reacting ammonia with calcium carbonate above 600 °C is another route.[5][6]. [5] Fritz Rothe, a colleague of Frank and Caro, succeeded in 1898 in overcoming problems with the use of calcium carbide and clarified that at around 1,100 °C not calcium cyanide but calcium cyanamide is formed in the reaction. This chemical is used as fertilizer and is commercially known as nitrolime. Here you can find all of the regulations and regulatory lists in which this substance appears, according to the data available to ECHA. The chemical formula for calcium cyanamide is CCaN. F. Brezina, J. Mollin, R. Pastorek, Z. Sindelar. [fertilizer] [Note: Commercial grades may contain calcium carbide.] EU. This directive requires employers to ensure proper signage is posted in areas where hazards cannot be avoided or reduced. Opposite motor responses elicited by ethanol in the posterior VTA: the role of acetaldehyde and the non-metabolized fraction of ethanol. The chemical formula for calcium cyanamide is CCaN. GHS02, GHS05, GHS07. The quality and correctness of the information submitted to ECHA remains the responsibility of the data submitter. In some places it's hard to find, as the compounds readily hydrolyzes in the presence of moisture, and water-sensitive materials are generally not sold in most stores due to safety. 2. , and its molecular weight is 80.11 g/mol. As urea (formed via the Haber–Bosch process) was significantly more nitrogen-rich (46% compared to ca. %%EOF The ‘Hazard classification and labelling’ section shows the hazards of a substance based on the standardised system of statements and pictograms established under the CLP (Classification Labelling and Packaging) Regulation. Substances for which an agreed set of classification and labelling data has been agreed at EU level by Member States. CAS Number. Examples include recommended measures on fire-fighting, transport and recycling and disposal. [14], Cyanamide calcium salt, Lime Nitrogen, UN 1403, Nitrolime, Except where otherwise noted, data are given for materials in their. Shanghai Jizhi Biochemical Technology Co., Ltd, calcium,(E)-4-oxopent-2-en-2-olate,hydrate, calcium,sodium,2-[bis[2-[carboxylatomethyl-[2-(methylamino)-2-oxoethyl]amino]ethyl]amino]acetate, calcium,5-(4-chlorophenoxy)pyridine-2-carboxylate, dust mask type N95 (US);Eyeshields;Faceshields;Gloves. The main use of calcium cyanamide is in agriculture as a fertilizer. 156-62-7. Derivatives of this compound are also referred to as cyanamides, the most common being calcium cyanamide (CaCN 2 ). 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. Calcium cyanamide must be kept in closed containers, away from moisture. This process requires meticulous temperature control since the melting point of calcium cyanamide is only about 120°C lower than the boiling point of sodium chloride. It is known to cause alcohol intolerance, before or after the consumption of alcohol. Substances potentially subject to further regulatory management. H.H. 2(b)(i) - Hazardous Agents, EU Ecolabels - Restrictions for Hazardous Substances/Mixtures, Workplace Signs - minimum requirements & signs on containers and pipes, Waste Framework Directive, Annex III - Waste - Hazardous Properties, CALCIUM CYANAMIDE with more than 0.1% calcium carbide, Inland Transport of Dangerous Goods Directive, Annex III - ADN, Inland Transport of Dangerous Goods Directive, Annex I - ADR, Inland Transport of Dangerous Goods Directive, Annex II - RID, EC Inventory, C&L Inventory, Registration dossier, Pre-Registration process, Other, CAD - Chemical Agents Directive, Art. Properties of concern are calculated at four "levels" of certainty: The following properties of concern are calculated: The substance properties displayed in this section are derived from Harmonised classification and labelling (CLH) data, entries in the Candidate list of substances of very high concern for authorisation, the PBT assessment list, the ED assessment list, REACH registered dossier data and from notifications made under CLP. The EC Inventory is a combination of three independent European lists of substances from the previous EU chemicals regulatory frameworks (EINECS, ELINCS and the NLP-list).
