Claims
- 1. A process for the preparation of a composition (D), comprising:mixing a sugar of formula (V): H-G-OH (V) in acidic medium with an excess of at least one alcohol of formula (VI): HO—RA (VI) thereby to form a reaction mixture comprising at least one alcohol of formula (VI) and at least one compound with the following formula (III): (G)x—O—RA (III), mixing said reaction mixture with a compound of the following formula (IV): HO—[CH2—CH(R1)—O]n—RB (IV), in a weight ratio of (III)/(IV) between 0.1 and 10, thereby to form a mixture comprising at least an alcohol of formula (VI), a compound of formula (III) and at least one compound of formula (IV),neutralizing said mixture, and distilling said mixture to obtain said composition (D), said (D) composition consisting essentially of: (a) at least one compound of the formula (III): (G)x—O—RA (III) and (b) at least one compound of the formula (IV): HO—[CH2—CH(R1)—O]n—RB (IV) wherein x represents a decimal number between 1 and 5, n represents an integer between 1 and 30, R1 represents hydrogen or methyl, G represents the residue of a saccharide, RA and RB represent independently of one another, a saturated or unsaturated, linear or branched hydrocarbon comprising 1 to 30 carbon atoms, and said composition (D) being devoid of water and of fatty alcohols.
- 2. A process as claimed in claim 1, wherein said saccharide is glucose, and x is between 1.05 and 2.5.
- 3. A process as claimed in claim 1, wherein RA and RB are, independently of one another, linear or branched hexyl, octyl, heptyl, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, hexadecyl, octadecyl, octadecenyl, octadecadienyl, or octadecatrienyl.
- 4. A process as claimed in claim 1, in which RA and RB are identical and are octyl, nonyl, decyl, or 2-ethylhexyl.
- 5. A process as claimed in claim 1, wherein said saccharide is glucose.
- 6. A process as claimed in claim 1, wherein RA and RB are identical.
- 7. A process as claimed in claim 1, wherein said saccharide is glucose, is mixed in acidic medium with an excess of a mixture of alcohols of formula (VI) in order to form a mixture of compounds of formula (VI) and compounds of formula (III),the last-named mixture is then mixed with a mixture of compounds (IV1) HO—[CH2—CH(R1)—O]n—RA (IV1) in a weight ratio of (III)/(IV) between 0.2 and 5, in order to form a mixture of compounds of formula (VT) and formula (I) and formula (IV), which mixture is then subjected to said neutralization and distillation steps.
