Ethylene glycol ether

Figure 6.3 Conparlson of the separation of the octylphenol poly(ethylene glycol) ether, Triton X-16S on a packed column, left, and an open tubular column, right, using UV detection. For the packed column separation al0cmx2mmI.D. column packed with Nucleosil C g, d. 3 micrometers, temperature > 170 C, and mobile phase carbon dioxide (2 ml/min] and methanol (0.15 nl/rnin). pressure programmed from 130 to 375 bar in 12 min were used. For the open tubular column separation a 10 m x 50 micrometers I.O., SB-Biphenyl-30, temperature = 175°C, mobile phase carbon dioxide (0.175 ml/min) and 2-propanol (0.0265 ml/min) pressure programmed, 125 bar for 5 min, then ramped from 125 to 380 bar over 19.5 min, and held at 380 bar for 15 min. were used.

Toxicology. Dipropylene glycol methyl ether (DPGME) at very high concentrations causes narcosis in animals, and it is expected that severe exposure will produce the same effect in humans. Because the propylene glycol ethers are metabolized differently from the ethylene glycol ethers, they are not associated with potent teratogenic, spermatotoxic, or hematopoietic effects. ...

Fermentation-derived organic acids and their esters are potentially important chemical feedstocks for polymers and specialty polymers, but most significantly as alternative solvents for industrial and consumer applications. For example, lactate esters are derived from renewable carbohydrate raw materials such as cornstarch. They exhibit much lower toxicity compared with halogenated hydrocarbons and ethylene glycol ethers and are environmentally benign. Some studies suggested that lactate ester solvents have the potential of replacing petroleum-based solvents... [Pg.376]

Surface active poly(ethylene glycol) ethers have been found to exert a aippressive effect on tuberculosis The greatest activity is observed wdien the number of ethylene oxide urtits is IS to 20 and the activity is completely abolished in those polymers where the number of imits ranges between 25 and 30. Conforth and coworkers have also found that when the number of ethylene oxide units was 45—70 the polymers, instead of displaying chemotherapeutic activity, significantly enhanced the infection, the so-caUed protuberculous effect. Thus, as the lipophflic to hydro-phflic ratio decreases, activity passes from antituberculosis to inactive protuberculous. These observations demonstrate the importance of two physical parameters in chemotherapy, namely surface activity and molecular size. [Pg.84]
