Patent

CA 2673036

This invention relates to a process of producing one or more of an alkylene glycol or poly-alkylene glycol by the reaction of an alkylene oxide and water whereby reduced levels of undesired by products such as carbonyl compounds, ultraviolet light absorbing compounds and various metal species are produced.

Cette invention porte sur un procédé de fabrication d'un ou de plusieurs types d'alkylène parmi un alkylène glycol et un polyalkylène glycol par la réaction d'un oxyde d'alkylène et d'eau, permettant ainsi d'obtenir des taux réduits de sous-produits indésirés tels que des composés carbonyle, des composés absorbant la lumière ultraviolette et diverses espèces métalliques.
