Title
(EN) DIALKYL AND DIARYL ETHER PRODUCTION FROM METAL ALCOHOLATE
(FR) PRODUCTION D'UN DIALKYL ET DIARYL ÉTHER À PARTIR D'UN ALCOOLATE MÉTALLIQUE
Abstract
(EN)
A dialkyl or diaryl ether is produced by reacting carbon dioxide with a metal alcoholate having the formula, M(RO)x, where "M" is a Group 1, Group 2, or Group 3 metal; "x" is the valence of the metal M; "R" is a C1 to C6 lower alkyl or aryl, wherein the reaction produces a dialkyl or diaryl ether having a formula, R-O-R, and a metal carbonate having a formula M2CO3 where M is a Group 1 metal, MCO3 where M is a Group 2 metal, and M2(CO3)3 where M is a Group 3 metal. The metal carbonate may be removed by conventional means, such as filtration. The dialkyl or diaryl ether may be recovered and used as a fuel, fuel additive, propellant, or building block for other fuels or petrochemicals.
(FR)
Un dialkyle ou diaryl éther est obtenu par réaction de dioxyde de carbone avec un alcoolate métallique ayant la formule, M(RO)x, où « M » est un métal du Groupe 1, du Groupe 2 ou du Groupe 3 ; « x » est la valence du métal M ; « R » est un alkyle inférieur en C1 à C6 ou un aryle, la réaction produisant un dialkyl ou diaryl éther ayant une formule, R-O-R, et un carbonate métallique ayant une formule M2CO3 où M est un métal du Groupe 1, MCO3 où M est un métal du Groupe 2, et M2(CO3)3 où un M est métal du Groupe 3. Le carbonate métallique peut être éliminé par des moyens classiques, tels que la filtration. Le dialkyl ou le diaryl éther peut être récupéré et utilisé comme combustible, additif pour combustible, propulseur ou composant de base pour autres combustibles ou produits pétrochimiques.
