Ion carbonyle
Carbonyl iron is a highly pure (97.5% for grade S, 99.5+% for grade R) iron, prepared by chemical decomposition of purified iron pentacarbonyl. It usually has the appearance of grey powder, composed of spherical microparticles. Most of the impurities are carbon, oxygen, and nitrogen. BASF invented carbonyl iron powder in 1925 and claims to be the world's leading producer. In 1934, BASF was also involved in the development of the very first magnetic tapes used by the … Webcomposer ultérieurement le support de catalyseur avec un composé organique comprenant au moins un atome d'azote lié de manière covalente et au moins une fraction carbonyle, sans calcination ultérieure, de telle sorte le catalyseur obtenu a un rapport du composé organique sur la teneur en métal d'hydrogénation totale d'au moins 0,01 : 1 ...
