2-Ethoxyethanol, oxidation

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. 

Imanaka—heterogenization of Rh complexes. In 1991, Imanaka and coworkers124 reported the heterogenization of Rh complexes by binding them to aminated polymers. As discussed previously, these findings led to fruitful research by Ford, Pardey, and others. The isolated polymer-bound Rh carbonyl anion complex was found to be reusable for reactions such as water-gas shift and reduction of nitro compounds. The polymer-bound Rh complexes were characterized by infrared spectroscopy. Water-gas shift activity (80 mol H2 per mol Rh6(CO)i6 in 24 hours) was recorded using the Rh complexes at 100 °C with 0.92 atm of CO, 2.16 ml H20, 0.05 mmol Rh6(CO)16, aminated polystyrene, 5.0 mmol of N, 5.56 ml ethoxyethanol and reduction of nitro-compounds (e.g., aliphatic nitro compounds to nitriles, oximes to nitriles, hydroxylamines to nitriles, and N-oxides to amines) occurred at 40 °C. 

Photolytic. Grosjean (1997) reported a rate constant of 1.87 x lO " cm /molecule-sec at 298 K for the reaction of 2-ethoxyethanol and OH radicals in the atmosphere. Based on an atmospheric OH radical concentration of 1.0 x 10 molecule/cm , the reported half-life of methanol is 0.35 d (Grosjean, 1997). Stemmier et al. (1996) reported a rate constant of 1.66 x 10 " cm /molecule-sec for the OH radical-initiated oxidation of 2-ethoxyethanol in synthetic air at 297 K and 750 mmHg. Major reaction products identified by GC/MS (with their yields) were ethyl formate, 34% ethylene glycol monoformate, 36% ethylene glycol monoacetate, 7.8% and ethoxyacetaldehyde, 24%.

Oxidative cyclization with DDQ of amino(ribosylamino)maleonitrile in methanol gives a 64% yield of 4-cyano-5-methoxy-2-(D-ribotetrahydroxybutyl)-imidazole, whereas an anomeric mixture of 2-(D-erythrofuranosyl)-4-cyano-5-methoxyimidazole is obtained in 77% total yield by heating the open chain species for 3h at 150°C in a mixture of 2-ethoxyethanol and acetic acid [41]. 

Resist films 0.5 to 1 ym thick were spin-coated on 3-inch diameter silicon wafers (oxide coated). The polymers were applied from 10% solutions in chlorobenzene, 2-ethoxyethanol, or 2-methoxyethyl acetate using a Headway Research Model EC-101D spinner. Prebaked (1 hr, 80°C, vac.) films were exposed to the e-beam and then extracted with about 4 ml of tetrahydrofuran, THF. About 4 to 8 hrs was allowed for dissolving to take place. Molecular weights were estimated using a Waters Model 201 HPLC equipped with 4 y-Styragel columns of nominal sizes 500, 10, ...

Uniform bimetallic copper-palladium colloids (the metals are completely miscible) have been prepared by thermolysis of mixtures of the acetates in high boiling solvents such as bromobenzene, xylenes, and methyl- o-butyl ketone [86] in the absence of polymer stabilizers. The resulting agglomerated bimetallic particles often contained CuO in addition to the metals. Smaller particle sizes and narrower size distributions without oxide formation were reported to result from the analogous reaction in 2-ethoxyethanol in the presence of PVR [38] In both cases the homogeneous composition of the particles was established during the electron microprobe analysis used to determine the Cu Pd ratio in the individual particles.
