Ethylene monoethyl ether

Cellosolve A trade name for ethylene glycol monoethyl ether. Also known as Oxitol. 

Glycol Ethers. The addition of one mole of ethylene oxide [75-21-8] to ethanol gives ethylene glycol monoethyl ether [109-86-4]. 

Diethylene glycol monoethyl ether [111-90-0] M 134.2, b 201.9", d 0.999, n 1.4273, n 1.4254. Ethylene glycol can be removed by extracting 250g in 750mL of benzene with 5mL portions of water, allowing for phase separation, until successive aqueous portions show the same volume increase. Dried, and freed from peroxides, as described for diethylene glycol mono-n-butyl ether.

The solubility of latex in water can be improved by replacing the solvent used in the system. Initially, the water is removed and than a hydrophobic organic solvent is replaced by a hydrophilic solvent, which has a boiling point above 100 C. This last solvent can be ethylene glycol, diethyl ether of diethylene glycol, monoethyl ether of ethylene glycol, or polyethylene glycols. This treatment results in a pastelike composition that can be easily mixed with water and used as a final product.

DMC and EG were main products of the transesterification reaction. No by-product such as dimethyl ether and glycol monoethyl ether was observed in the resulting products. Only small peaks of ethylene oxide from the decomposition of EC could be detected at longer reaction time and at high temperature. 

In addition, water motion has been investigated in reverse micelles formed with the nonionic surfactants Triton X-100 and Brij-30 by Pant and Levinger [41]. As in the AOT reverse micelles, the water motion is substantially reduced in the nonionic reverse micelles as compared to bulk water dynamics with three solvation components observed. These three relaxation times are attributed to bulklike water, bound water, and strongly bound water motion. Interestingly, the overall solvation dynamics of water inside Triton X-100 reverse micelles is slower than the dynamics inside the Brij-30 or AOT reverse micelles, while the water motion inside the Brij-30 reverse micelles is relatively faster than AOT reverse micelles. This work also investigated the solvation dynamics of liquid tri(ethylene glycol) monoethyl ether (TGE) with different concentrations of water. Three relaxation time scales were also observed with subpicosecond, picosecond, and subnanosecond time constants. These time components were attributed to the damped solvent motion, seg-... 

Davidow (19), of the Food and Drug Administration, has described a colorimetric method applicable to technical chlordan. The method is based on the observation that when technical chlordan is heated with a mixture of diethanolamine and methanolic potassium hydroxide, a purple color is produced. When known amounts of this insecticide were added to cabbage, pears, and fresh and rancid rat fat, recoveries of 74 to 104% of the insecticide were obtained. However, because two crystalline isomers of chlordan isolated from the technical product do not give a colored reaction product with the reagent, further investigation of the method is being made. The red color obtained when technical chlordan is heated with pyridine, alcoholic alkali, and ethylene glycol monoethyl ether, as described by Ard (2), likewise fails with the crystalline isomers of this insecticide. 

Poisons. These were the phosphorofluoridates prepared by the Cambridge team of chemists (pp. 2-7), and eserine. Since the phosphorofluoridates slowly hydrolyse in water, stock solutions of these and of eserine were prepared in ethylene glycol monoethyl ether, and... 

Fluoro- and 2-hydroxy-2 -2"-fluoroethoxydiethyl ether were both toxic the former had a l.d. 50 of 15-20 mg./kg. and the latter of 30-40 mg. /kg. If the former is readily oxidized to the corresponding acid in the animal body, then we should expect it to be non-toxic in view of the non-toxicity of ethyl 2-fluoroethoxyacetate referred to above. It must be concluded then that the ether alcohols exert some toxic action per se. Ethylene glycol monoethyl ether, was examined physiologically but was found to be non-toxic,1 showing that the activity of 2-fluoro-2 -hydroxydiethyl ether was again closely associated with the 2-fluoroethoxy group in the molecule.
