Abstract:
A process for preparing a composition (C 1 ) represented by the formula (I): HO—CH 2 —(CHOH) n —CH 2 —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 (A 1 ): HO—CH 2 —(CHOH) n —CH 2 —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 (C a ), and in that the acid catalyst (C a ) is chosen from phosphorous acid, phosphoric acid and polyphosphoric acid.

Claim (Index 1):
A process for preparing a composition (C 2 ), said composition (C 2 ) comprising, per 100% of its weight:\n from 1% to 70% by weight of a polyol of formula (A 1 ):\n HO\u2014CH 2 \u2014(CHOH) n \u2014CH 2 \u2014OH\u2003\u2003(A 1 ), \n in which n is an integer equal to 2, 3 or 4;\n from 25% to 98.9% by weight of a composition (C 1 ) represented by the formula (I):\n HO\u2014CH 2 \u2014(CHOH) n \u2014CH 2 \u2014O-(G) x -H\u2003\u2003(I), \n \n in which G represents the residue of a reducing sugar selected from the residues of glucose, xylose and arabinose, n is an integer equal to 2, 3 or 4 and x, which indicates the mean degree of polymerization of said residue G, represents a decimal number of greater than 1 and less than or equal to 5;\n from 0.1% to 5% by weight of a compound (B) or of a mixture of compounds (B) chosen from:\n the compound of formula (B 11 ): \n \n the compound of formula (B 12 ): the compound of formula (B 13 ): and the compound of formula (B 14 ): said process comprising at least one stage a) of reaction of a polyol of formula (A 1 ):\n HO\u2014CH 2 \u2014(CHOH) n \u2014CH 2 \u2014OH\u2003\u2003(A 1 ), \n in which n is an integer equal to 2, 3 or 4, with a reducing sugar of formula (II):\n HO-G-H\u2003\u2003(II) \n in which G represents the residue of a reducing sugar, in the presence of an acid catalyst (C a );\n wherein said acid catalyst (C a ) is chosen from hypophosphorous acid, phosphoric acid and polyphosphoric acid; \n wherein, in stage a), the molar ratio, of a reducing sugar of formula (II) to polyol of formula (A 1 ), is greater than or equal to 1/6 and less than or equal to 4/1; and \n wherein, in stage a), the proportion by weight of acid catalyst (C a ) employed is greater than or equal to 0.05% and less than or equal to 2% per 100% of the sum of the weights of a reducing sugar of formula (II) and of polyol of formula (A 1 ).
