Silver acetylide can be formed on the surface of silver or high-silver alloys, e.g. Silver acetylide is an inorganic chemical compound with the formula Ag2C2, a metal acetylide. You do not need to reset your password if you login via Athens or an Institutional login. Buying Leads | Product Classification | Articles of sodium acetylide are included as well. With nitric acid present in solution, a double salt is produced, probably a mixed salt/covalent bonding type of compound, with the nitrate ion present as a real ion and the acetylide connected to the silver atoms in a mostly covalent bond. It is more dense than water so it all sinks nicely to the bottom. The sodium acetylide product is, of course, a salt. diazonium salts, halides of organic acids, and organometallic compounds. Congratulations on this excellent venture… what a great idea! Dany . The salt's anion consists of two carbon atoms linked by a triple bond. For corporate researchers we can also follow up directly with your R&D manager, or the information For a long time, it was assumed to have the unusual property that on ignition it does not evolve any gas, only decomposing through the reaction: However, it has been shown that some gaseous products do form, containing water, carbon dioxide, carbon monoxide, hydrogen, and methane. "Ueber eine neue Klasse zusammengesetzter metallhaltiger Radicale (A new class of combined metallic radicals)". The salt's anion consists of two carbon atoms linked by a triple bond.

Silver acetylide is an inorganic chemical compound with the formula Ag2C2, a metal acetylide. Terminal alkynes can also form salts with certain heavy-metal cations, notably silver(I) and copper(I). I use WIKI 2 every day and almost forgot how the original Wikipedia looks like. It is sometimes called as silver carbide and is expressed using the formula . This is the same synthesis from Berthelot in which he first found silver acetylide in 1866.[2].

Silver acetylide is a high explosive. Any problem here? silver acetylides and their physical properties is given. This site uses cookies. New double salts 3 and 4 are now obtained by dissolving silver acetylide in an aqueous solution of silver trifluoromethanesulfonate (triflate) followed by addition of acetonitrile or propionitrile. That's it. | Service | PubChem Substance ID 24855004. On raising the acetylene flow rate the proportion of the carbon-aceous substance is raised to 5-6%, but that of Cu(OH) falls. above types of compounds and the mechanism of the oxidative condensation of acetylenes are considered. in pipes used for transport of acetylene, if silver brazing was used in their joints. The detonation velocity of the silver acetylide-silver nitrate double salt is 1980 m/s, while that of pure silver acetylide is 1200 m/s.[3]. 2 The above investigations were carried out with acetyl-ides obtained in alkaline solutions. The alternate name "silver carbide" is rarely used, although the analogous calcium compound CaC2 is called calcium carbide. Copyright © 2003 Elsevier Science B.V. All rights reserved.

The alternate name "silver carbide" is rarely used, although the analogous calcium compound CaC2 is called calcium carbide. solution of copper (I) salt contains on average 91-93% of an acetylide of the empirical formula (Cu2C 2) 2.H 2 O, 4-6% Cu(OH) 2, and 3-5% of a carbonaceous substance. To install click the Add extension button. Silver Acetylide DS storage Hi, I am thinking the best way to store silver acetylide double salt (1-4 grams) is under clean distilled water in a plastic sealed container in a dark cool environment. You will only need to do this once. It will enhance any encyclopedic page you visit with the magic of the WIKI 2 technology. Number 10, A M Sladkov and Lev Yu Ukhin 1968 Russ. However, no double salt of silver acetylide with silver triflate has been reported so far. Instead of the conventional synthesis of passing acetylene gas through silver nitrate solution, an amateur chemist by the username fdnjj6 discovered that a purer and whiter precipitate can be formed by passing acetylene gas through acetone and adding the acetylene solution drop-wise to a dilute silver nitrate and nitric acid solution. Performing the synthesis in basic ammonia solution does not allow the double salt to form, producing pure silver acetylide. Silver acetylide can be produced by passing acetylene gas through a solution of silver nitrate:[1], The reaction product is a greyish to white precipitate. The compound can be regarded as a salt of the weak acid, acetylene. RIS. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. Pure silver acetylide is a heat- and shock-sensitive high explosive. Silver acetylide is not soluble in water and is not appreciably soluble in any other solvent.
