Certain alcohol initiators containing halogen, aldehyde, ketone or nitro substitution can be alkoxylated with excellent efficiency and low production of by-products using a metal cyanide catalyst. The products contain halogen, aldehyde, ketone or nitro groups that can undergo subsequent reactions to form amino groups.
Selon l'invention, certains initiateurs d'alcool comprenant une substitution halogène, aldéhyde, cétone ou nitro peuvent être alcoxylés, au moyen d'un catalyseur à base de cyanure pour métaux, de manière efficace et avec une faible production de sous-produits. Les produits contiennent des groupes halogène, aldéhyde, cétone ou nitro pouvant subir des réactions consécutives de manière qu'ils forment des groupes amino.
