EC number: 270-745-6 | CAS number: 68477-64-5 The gas produced by the reaction of oxygen with natural gas to obtain acetylene. It consists primarily of hydrogen, carbon monoxide, carbon dioxide, natural components of air and hydrocarbons having carbon numbers predominantly in the range of C1 through C2.

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
