Surfactant composition comprising ether compound and catalytic process for manufacturing thereof
First Claim
1. A process for preparing at least one ether compound, the process comprising reacting at least one alcohol (I) with at least one polyol (II) in the presence of a functional polymer [polymer (F)] as a catalyst (X), wherein:
- the alcohol (I) is a compound represented by the general formula (1);
R1—
OH
(1)wherein R1 is a hydrocarbon group having 1 to 36 carbon atoms, the polyol (II) is represented by the general formula (2);
R2—
(OH)m
(2)wherein R2 represents the skeleton moiety of the polyol and m is an integer of from 2 to 20,and the polymer (F) is a polymer comprising recurring units derived from at least one ethylenically unsaturated monomer [monomer (M)] and bearing at least one cation exchange group;
wherein the reaction of the at least one alcohol (I) with the at least one polyol (II) in the presence of the functional polymer [polymer (F)] as the catalyst is performed in the absence of a solvent, and a medium for the reaction of the at least one alcohol (I) with the at least one polyol (II) in the presence of the functional polymer [polymer (F)] as the catalyst is substantially free of any surfactant at the start of the reaction.
