Title (EN) ISOCYANATE MANUFACTURE
(FR) FABRICATION D'ISOCYANATES
Abstract: front page image
(EN)The present invention encompasses the finding that improvements can be achieved in manufacture of isocyanates through the use of a substitute for or a precursor of phosgene. Methods and compositions utilized in accordance with the present invention can be useful in situations in which it is difficult to use phosgene, and in particular gaseous phosgene. In some embodiments, a substitute for or a precursor of phosgene used in accordance with the present invention for preparing isocyanates is or comprises diphosgene (ClCO2CCl3).
(FR)La présente invention comprend la découverte selon laquelle des améliorations peuvent être apportées dans la fabrication d'isocyanates grâce à l'utilisation d'un substitut ou d'un précurseur de phosgène. Des procédés et des compositions, utilisés selon la présente invention, peuvent être utiles dans des situations dans lesquelles il est difficile d'utiliser du phosgène, et en particulier du phosgène gazeux. Dans certains modes de réalisation, un substitut ou un précurseur de phosgène, utilisé selon la présente invention pour préparer des isocyanates, est ou comporte du diphosgène (ClCO2CCl3).
