A process for the preparation of acylated secondary alcohol alkoxylates, said process comprising : (i) reaction of one or more internal olefins with one or more carboxylic acids in the presence of a catalyst composition in order to form one or more carboxylic acid esters; (ii) reaction of one or more carboxylic acid esters from step (i) with one or more alkylene oxide reactants, in the presence of a catalytically effective amount of a catalyst composition comprising: (a) one or more alkaline earth metal salts of carboxylic and/or hydroxycarboxylic acids and/or hydrates of the former; (b) an oxy-acid selected from sulphuric acid and ortho-phosphoric acid; (c) an alcohol and/or an ester; and/or products of the reciprocal reactions of (a), (b) and/or (c) in order to form one or more acylated secondary alcohol alkoxylates; and optionally (iii) hydrolysis or transesterification of one or more acylated secondary alcohol alkoxylates from step (ii) in order to form one or more secondary alcohol alkoxylates; and a process for making secondary alcohol alkoxy sulphates comprising the steps of: preparing secondary alcohol alkoxylates by the afore-mentioned process; and sulphating the secondary alcohol alkoxylates.
Procédé de préparation dalcoxylates d'alcools secondaires acylés, ledit procédé comprenant : (i) la réaction d'une ou de plusieurs oléfines internes avec un ou plusieurs acides carboxyliques en présence d'une composition catalytique pour former un ou plusieurs esters d'acide carboxylique; (ii) la réaction d'un ou de plusieurs esters d'acide carboxylique de l'étape (i) avec un ou plusieurs réactifs de type oxyde d'alkylène, en présence d'une quantité catalytiquement efficace d'une composition catalytique comprenant : (a) un ou plusieurs sels de métaux alcalino-terreux d'acides carboxyliques et/ou hydroxycarboxyliques et/ou d'hydrates desdits sels; (b) un oxyacide choisi parmi l'acide sulfurique et l'acide orthophosphorique; (c) un alcool et/ou un ester; et/ou les produits des réactions réciproques de (a), (b) et/ou (c) pour former un ou plusieurs alcoxylates d'alcools secondaires acylés; et éventuellement (iii) l'hydrolyse ou la transestérification d'un ou de plusieurs alcoxylates d'alcools secondaires acylés de l'étape (ii) pour former un ou plusieurs alcoxylates d'alcools secondaires; et procédé de production dalcoxysulfates d'alcools secondaires comprenant les étapes suivantes : préparation d'alcoxylates d'alcools secondaires par le procédé décrit ci-avant; et sulfatation des alcoxylates d'alcools secondaires.
