| titleOfInvention | A process for making butyl ethers of glycols |
| abstract | A process for the production of n-butyl glycol ether which comprises: (i) forming a mixture of n-butenyl glycol ether and secondary butenyl glycol ether by reacting butadiene with a saturated aliphatic glycol in the presence of a heterogeneous catalyst which is modified by the addition of at least one counterion selected from the group consisting of: an alkyl pyridinium quaternary ammonium, quaternary arsonium and quaternary phosphonium; (ii) separating the n-butenyl glycol ether and secondary butenyl glycol ether formed in step (i); and (iii) hydrogenating the n-butenyl glycol ether separated in step (ii) in the presence of a catalyst to the corresponding n-butyl glycol ether. |
