Homologous mono-alkyl ethers of ethylene glycol, such as monoethyl glycol (or 2-ethoxyethanol), HOC2H4OC2H5, form excellent solvents as they combine to a large extent the solvent properties of alcohols and ethers. The monoethyl and the monomethyl members have the technical names of ethyl cellosolve and methyl cellosolve respectively. Dioxan... 

In general, the tetracyclines are yellow crystalline compounds that have amphoteric properties (Fig. 2) (15). They are soluble in both aqueous acid and aqueous base. The acid salts tend to be soluble in organic solvents such as 1-butanol, dioxane, and 2-ethoxyethanol In fact, 1-butanol is used to extract the salts from aqueous solution. 

Butyl glycol ethers, the largest volume derivatives of -butyl alcohol used ia solvent appHcations (10), are obtained from the reaction of 1-butanol with ethylene oxide. The most important of these derivatives, 2-butoxyethanol, is used principally ia vinyl and acryHc paints as well as ia lacquers and varnishes. It is also employed ia aqueous cleaners to solubilize organic surfactants. 2-Butoxyethanol [111-76-2] has achieved some growth at the expense of the lower alkoxyethanols (ie, methoxy and ethoxyethanol) because of 2-butoxyethanol s lower toxicity. 

Many catalysts are sold as water-wet and are useful when water can be tolerated. These wetted catalysts are much less apt to start fires. Catalysts can be wetted with safety with methylcellosolve (2 ethoxyethanol) before adding them to volatile solvents 40). 

A mixture of benzo[/]isoindolinediimine (1.5g, 7.7 mmol), RuClj 3H20 (500mg, 1.9 mmol), DBU (1.02 g, 1 mL, 6.5 mmol), and 2-ethoxyethanol (30 mL) was refluxed for 24 h. After cooling, the mixture was poured into McOH and the precipitate was filtered, dried, and washed with hexane. The residue was stirred in pyridine for 1 h at 100 C. Excess solvent was removed at reduced pressure and the crude product was purified by column chromatography (silica gel. CHCI,) and dried at 100 C/0.01 Torr yield 610 mg (67%). 

To obtain a sample, the reactor was manually pressurized with nitrogen to 10 to 12 psi, and the four-port switching valve was activated to divert the flow of reactor solvent to recycle. The pressure forced about 4 ml of sample through the 5-pl slot of the tantalum valve. The valve was then switched to transfer the sample to the HPLC located about 15 feet away. The solvent for transfer and dynamic dilution was ethoxyethanol, with a boiling point of... 

On April 8, 2003, U.S. EPA proposed to add benzene and 2-ethoxyethanol to the list of solvents whose mixtures with wastewater are exempted from the definition of hazardous waste.23 U.S. EPA is proposing to provide flexibility in the way compliance with the rule is determined by adding the option of directly measuring solvent chemical levels at the headworks of the wastewater treatment system. In addition, U.S. EPA is proposing to include scrubber waters derived from the combustion of spent solvents to the headworks exemption. Finally, U.S. EPA is finalizing the Headworks Rule, as follows24 ...

R,5)-lbuprofen acid (20 g, 96.9 mmol), p-toluenesulfonic acid (0.44 g, 2.27 mmol) and 2-ethoxyethanol (21.9 mL, 224 mmol) were dissolved in the organic solvent, isooctane (180 mL). The boiling chips were added into the reaction flask as anti-bumping agent. Then the reaction mixtures were refluxed for 8—9 h using a Dean-Stark apparatus.

Thermal decomposition of metal acetates in the presence of PVP was proposed by Bradley et al. (30), where the preparative procedure of Esumi et al. (31) was modified. Thus, heating of palladium and copper acetates in a solvent with a high boiling point (ethoxyethanol) provides PVP-stabilized Pd/Cu bimetallic nanoparticles. In this method, not only thermal decomposition but also reduction by ethoxyethanol could be involved. However, the Bradley method can provide Cu/Pd bimetallic nanoparticles that contain less than 50 mol% of Cu, while our method mentioned earlier can provide fine particles with 80 mol% of Cu. In Esumi s original procedure, methyl iso-butyl ketone (MIBK) was used as a solvent without a stabilizer. In his method, Cu" was not completely reduced to Cu°, but Cu20 was involved in the bimetallic nanoparticles. Probably, thanks to Cu1 species in the surface of the particles, no stabilizer is necessary for the stable dispersion.

Ford and co-workers have also recently developed a homogeneous catalyst system for the water-gas shift reaction (95). Their system consists of ruthenium carbonyl, Ru3(CO)12, in an ethoxyethanol solvent containing KOH and H20 under a CD atmosphere. Experiments have been conducted from 100-120°C. The identity of the H2 and CD2 products has been confirmed, and catalysis by both metal complex and base has been verified since the total amount of H2 and COz produced exceeds the initial amounts of both ruthenium carbonyl and KOH. The authors point out that catalysis by base in this system depends on the instability of KHC03 in ethoxyethanol solution under the reaction conditions (95). Normally the hydroxide is consumed stoichiometrically to produce carbonate, and this represents a major reason why a water-gas shift catalyst system has not been developed previously under basic conditions. As has been noted above, coordinated carbonyl does not have to be greatly activated in order for it to undergo attack by the strongly nucleophilic hydroxide ion. Because of the instability of KHC03... 

Figure 7 shows the degradation quantum yield, d of a-guaiacoxyacetoveratrone in 7 deaerated solvents acetonitrile (ACN), dioxane (DIOX), 1,2-dimethoxyethane (DME), methanol (MeOH), ethanol (EtOH), isopropanol (iPrOH) and ethoxyethanol (EtOEtOH) (40,41). The 4 was significantly larger in alcohols, 0.34 to 0.52, than in pure aprotic solvents, < 0.1. There was very little difference in d in polar aprotic solvents, 0.08 in acetonitrile, compared to that in non-polar aprotic solvents,... 

Reproductive System. Epoxy resins and curing agents themselves do not seem to affect pregnancy and reproduction in humans. However, some of the diluents and solvents that are used may affect reproduction. Two solvents sometimes found in epoxy resin systems (ethoxyethanol and methoxyethanol) have been determined to cause birth defects in laboratory animals and reduced sperm counts in men. Some diglycidyl ethers also damage the testes and cause birth defects in test animals. It is not known whether these materials cause the same effect in humans. 

Cellosolve is the trade name for 2-ethoxyethanol, a common industrial solvent. This compound is produced in chemical plants that use ethylene as their only organic feedstock. Show how you would accomplish this industrial process. 

The complexes are very soluble in methanol, ethanol, butanol, methyl Cellosolve (2-methoxyethanol), and ethyl Cellosolve (2-ethoxyethanol), and to a fair degree, quite soluble in 1,2-dimethoxyethane and di- and triglyme. They are initially quite soluble in tetrahydrofuran, acetone, pyridine, nitro-methane, acetonitrile, dimethyl sulfoxide, and iV,A/-dimethyl-formamide, but usually precipitation of the nickel halide-solvent complex occurs if attempts are made to prepare moderately concentrated solutions in these solvents. They are only very slightly soluble, or are quite insoluble in dioxane, ethyl ether, hexane, dichloromethane, ethyl acetate, and methyl- and butyl-cellosolve acetate (2-methoxyethyl and 2-butoxyethyl acetate). 

Cellosolve C2H5O.CH2.CH2OH (2-ethoxyethanol, ethylene glycol monoethyl ether). The commercial solvent is a clear liquid with a characteristic odour. It has a density of 0 93 g cm-3 and boils at 134°C. 

For the work discussed in the following sections, we have used as low temperature laser solvents for BTFA chelates a 2 1 1 mixture of / -ethoxypropionitrile, -ethoxyethanol, and acetonitrile, (EEA), which forms a clear medium to about 135 °K., and a mixture, reported by Samelson, Lempicki, and Brecher (26), of equal parts of propionitrile, butyronitrile, and isobutyronitrile ( nitrile solvent ) which seems to remain clear at lower temperatures. 

The protic solvents most widely used are methanol, ethanol, ethoxyethanol and methoxyethanol in which most organic molecules are soluble. Aprotic solvents that have found extensive use are diglyme, dimethoxyethane, tetrahydrofuran, methylene chloride and chloroform.
