  • Process for making symmetrical alkanediols and the bis-ethers thereof
    Patent number: 4434032
    Abstract: A process for making symmetrical alkanediols and the bis-ethers thereof by electrochemically coupling the haloalkylethers that are the equivalent of one-half of the symmetrical bis-ether. A symmetrical alkanediol may be obtained from the symmetrical bis-ether. The method significantly increases the yield of alkanediols as for example 1,4-butanediol from electrochemical processes.
