Abstract
A process for preparing a composition (C1) represented by the formula (I): HO—CH2—(CHOH)n—CH2—O-(G)x-H, in which G represents the remainder of a reducing sugar, n is an integer equal to 2, 3 or 4 and x, which indicates the mean degree of polymerization of the remainder G, represents a decimal number greater than 1 and less than or equal to 5, characterized in that the process includes at least one step a) of reacting a polyol of formula (A1): HO—CH2—(CHOH)n—CH2—OH, in which n is an integer equal to 2, 3 or 4, with a reducing sugar of formula (II): HO-G-H, in which G represents the remainder of a reducing sugar, in the presence of an acid catalyst (Ca), and in that the acid catalyst (Ca) is chosen from phosphorous acid, phosphoric acid and polyphosphoric acid.
