PROCESS FOR THE REDUCTION OF REGIOISOMER WHERE THE DOUBLE BOND IS SHIFTED FROM ETHYLENICALLY UNSATURATED ALKOXYLATED ALCOHOLS
The present invention relates to 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, andn = 2 - 350,from a mixture comprising 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 said process comprises a treatment of said mixture comprising or consisting of a compound I and an alkoxylated alcohol A with an acid.The present invention also relates to the use of such alkoxylated alcohols A for the production of polycarboxylate ethers.
