PROCESS FOR THE REDUCTION OF REGIOISOMER WHERE THE DOUBLE BOND IS SHIFTED FROM ETHYLENICALLY UNSATURATED ALKOXYLATED ALCOHOLS
A process for the reduction of the content of a compound I of general formula (II)where R1 is hydrogen or methyl, each R2, independently from each other, is hydrogen or methyl, R3 is hydrogen or an aliphatic or cycloaliphatic or aromatic hydrocarbon with 1-8 carbon atoms, AO is a C2-C12 oxyalkylene group, x=0 or 1, and n=2-350, from a mixture including or consisting of a compound I of general formula (II) and an alkoxylated alcohol A of general formula (I)where R1, R2, R3, AO, x, and n are as described in general formula (II) above, characterized in that the process includes a treatment of the mixture including or consisting of a compound I and an alkoxylated alcohol A with an acid. Also, the use of the alkoxylated alcohols A for the production of polycarboxylate ethers.
