Patent number: 9273019Abstract: There is provided a process for manipulating the amount of alkyl alcohol in a product stream, e.g., such as an alkylene oxide product stream. More particularly, and in contrast to conventional processes wherein substantially all of the alkyl alcohol must be separated and desirably recycled, in the present process, a greater amount of alkyl alcohol may be allowed to remain in a partially refined alkylene oxide product stream. The residual alkyl alcohol is subsequently substantially entirely reacted to form a downstream product, e.g., a glycol ether, which is more easily separated from the alkylene oxide product stream. Indeed, the amount of alkyl alcohol in the partially refined alkylene oxide product stream can be selected based upon the output of glycol ethers, if desired.Type: GrantFiled: July 22, 2015Date of Patent: March 1, 2016Assignee: Dow Global Technologies LLCInventors: Tina L. Arrowood, Derrick W. Flick, John F. Ackford
