DGA = Diglycol amine Jefferson Chemical Co., Fluor patented process (Econamine)... 

Econamine A process for removing acid gases from natural gas by selective absorption in diglycolamine (also called [2-(2-aminoethoxy) ethanol], and DGA). Developed by the Fluor Corporation, the El Paso Natural Gas Company, and the Jefferson Chemical Company and widely used. Later versions, developed by Fluor Daniel International, include the Fluor Daniel Econamine and the Econamine FG processes. More than 30 units were operating in 1996. See also Aromex. 

Jefferson Chemical Company, Austin, Texas), for the fiber surface analog. This substitution was made since the fabric used in this study had a PEG fabric finish. This fabric finish differed from the Jeffox PEG-300 only in the fact that the former was higher molecular weight and therefore solid, while the latter was a liquid and amenable to SDIT measurement of and Yfs- With these values, the remaining eight surface parameters can be calculated. 

Ethylene carbonate obtained from the Eastman Kodak Company or the Jefferson Chemical Company was vacuum distilled and the fraction, b.p. 125°/10 mm., was used. 

American Cyanamid, nonetheless, still considered itself a chemical enterprise and entered polymer/petrochemicals on the basis of its capabilities developed in plastics before World War 11. It became competitive in the production of acrylonitrile and then acrylic fiber. For the production of its intermediates, it formed in 1944 a joint venture with Texaco, the Jefferson Chemical Company. ...

The sources of amines included Geigy, Dow, Union Carbide, Jefferson Chemical, Ames Laboratories, and Matheson Coleman and Bell. Tertiary amines were generally obtained by N-permethylation of the corresponding technical-grade amine fraction using common techniques (16). 

In addition, bis(2-hydroxypropy 1) isophthalate (Arco Chemical Co.) and bis(2-hydroxyethyl) carbamate (Jefferson Chemical Co.) have been introduced into the market.
