Chemical Designations - Synonyms Bis(2-chloroethyl) Ether 2,2 -Dichloroethyl Ether Dichlorodiethyl Ether Di-(2-chloroethyl) Ether Chlorex DCEE beta,beta -Dichloroethyl Ether Chemical Formula (ClCHjCH2)20. [Pg.117]

Chlorex (1) A process for extracting lubricating oil stocks from petroleum fractions using 0,0-dichloro diethyl ether. Chlorex is also the trademark for this compound. Developed by Standard Oil Company (Indiana) in the early 1930s and used until the 1960s. [Pg.63]

Chlorex (2) A process for removing hydrogen chloride from hydrocarbons by aqueous alkaline extraction, using a bundle of hollow fibers. Developed by the Meridiem Company, Houston, TX and used in three installations in Japan in 1991. [Pg.63]

The extraction of TcO with methyl ethyl ketone, acetone, and pyridine results in a ruthenium decontamination factor of about 10 . Another effective separation method is based on the extraction of technetium as triphenylguanidinium pertechnetate from sulfuric acid by means of chlorex ()S-chloroethyl ether). Pertechnetate can be re-extracted with 3 N NH OH solution . [Pg.126]

Solvents used in commercial operations at the present time are furfural, phenol, cresylic acid, Chlorex, nitrobenzene, and sulfur dioxide. The Duosol process utilizes a solvent called Selecto which is a mixture of phenol and cresylic acid. The propane used in the Duosol process precipitates the asphalt (18). [Pg.185]

Chlorex (/3,/3 -dichlorodiethyl ether) also has a high solvent power which makes it particularly suitable for Pennsylvania-type oils. The hydrogen chloride in commercial Chlorex (5.5 mg. per 100 ml.) must be removed before use to prevent corrosion of common construction materials. Injection of ammonia into recovery system vapor lines is required to control corrosion. [Pg.185]

Chlorex Process (0,/3 -Dichloroethyl Ether). The Chlorex process developed by Standard Oil (Indiana) (8) was patented in 1934. The first commercial plant to be put into operation was at Casper, Wyo., in June 1932. By August 1936 there were seven commercial plants in operation with a total throughput of 6150 barrels daily. [Pg.188]

Because of its high solvent power, Chlorex extraction takes place at 75° to 150° F. Such ambient temperature operation effects heating and cooling economies but necessitates dewaxing prior to extraction or the use of scraped exchangers. [Pg.188]

The Chlorex process utilizes simple countercurrent mixing and settling tanks (four to seven stages) or modern vertical packed towers. Solvent recovery involves conventional flash columns and strippers operated under vacuum (26 to 28 inches of mercury) at about 300° to 325° F. Low temperatures are desirable to minimize decomposition and formation of hydrochloric acid. [Pg.188]
