Patent number: 9822087Abstract: There is provided a manufacturing assembly for the production of an alkylene oxide and a stream of glycol ethers. The manufacturing assembly produces the alkylene oxide and stream of glycol without the use of equipment for separating substantially all of the alkyl alcohol from the alkylene oxide product stream. Thus, the use of additional pieces of equipment can be avoided, or the equipment required to effectuate any required further separation and/or purification may be smaller and/or cheaper to purchase and/or operate.Type: GrantFiled: February 12, 2016Date of Patent: November 21, 2017Inventors: Tina L. Arrowood, Derrick W. Flick, John F. Ackford

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

Patent number: 8722944Abstract: The invention relates to processes for the etherification of olefins with alcohols. According to one aspect, a heterogeneous etherification catalyst is used under conditions that permit limiting the contact time between the desired product and the catalyst, thereby mitigation reverse reactions. According to a second aspect, a recycling process is used that significantly increases the yield of desired product.Type: GrantFiled: April 27, 2009Date of Patent: May 13, 2014Assignee: Dow Global Technologies LLCInventors: Edward D. Daugs, Derrick W. Flick, Cynthia L. Rand, Michael L. Tulchinsky, Wanglin Yu

Patent number: 8541629Abstract: Glycol ethers are made by a process in which an alcohol, an alkylene oxide and a catalytic amount of an aromatic, heterocyclic amine catalyst are contacted under reactive conditions. Representative catalysts include substituted and unsubstituted pyridines and imidazoles. The process uses known oxides and alcohols, and produces more mono- and di-adduct products than does a corresponding process using a caustic catalyst. Moreover, the process can be conducted at a lower reaction temperature than a corresponding process using a caustic catalyst without sacrificing oxide conversion rates yet producing fewer carbonyl impurities.Type: GrantFiled: April 17, 2009Date of Patent: September 24, 2013Assignee: Dow Global Technologies LLCInventors: Scott P. Christensen, Derrick W. Flick
