Fig. 7. The effect of various substances on the spin-state equilibriutn of bacterial cytochrome P-450. The fraction of protein in the high-spin state is plotted (in arbitrary units) against the concentration (in fiM) of the natural effector putidaredoxin (Pd°) or the concentration in percent (v/v) of the organic solvents ethylene glycol or n-butanol. It is apparent that butanol induces a shift in spin state which is similar to that induced by the protein effector.

Only one paper that we are aware of explores a combined synthesis and processing route to aluminosilicates. Kemmitt and Milestone use precursors made by reaction of sodium hydroxide, boehmite [Al(0)OH] and silica in ethylene glycol in a 4 3 1 ratio160. The precursor structures are related to those shown above. On removal of solvent (ethylene glycol) a glycolate precursor is obtained that contains a pentacoordinated... [Pg.2305]

The TR ESR spectrum of IRG651 in a viscous solvent ethylene glycol was subjected to a detailed analysis in Ref. 36. It was assumed that in ethylene glycol the following holds true T2. This assumption allows the simplification of calculations and to obtain for 1,1-dimethoxybenzyl radical T 2 = 0.8 J,s. ... [Pg.260]

Closely related to these investigations, Breslow and co-workers studied the Diels-Alder reaction of CP with methyl vinyl ketone (MVK) in water-like solvents, ethylene glycol and formamide, in the presence of lithium salts. They found clear differences and similarities between water and these two solvent systems. In the absence of Li salts, the second-order rate constant for the reaction at 20 °C increased in formamide ( 2 = 3184 X 10 m s" ), and even more in ethylene glycol (480 x 10 m" s" ), relative to a polar solvent such as methanol (75.5 x 10 m" s ) or non-polar solvent such as isooctane (5.940.3 x 10 m s ). The reactions in both polar solvents were faster in the presence of LiC104 than in the presence of LiCl, although the perchlorate ion has less salting-out effect than chloride ion in water [41].

D-glucose, D-galactose, and D-ribose have subsequently been prepared, however, by the action of potassium fluoride on the isopropylidene-pro-tected, primary sulfonic esters at elevated temperatures in a suitable solvent. Ethylene glycol appears to be the best solvent, although a large proportion of the 2-hydroxyethyl ether is formed in the preparation of... [Pg.179]

Currently, other catalytic systems have been developed, including N, M -disubstituted o-phenylenediamines, thiazolium cyclophane, ° and enzymes. The benzoin cndensa-tion is normally carried out in aqueous solution, and the addition of salt (LiCl, KCl) can increase the reaction rate however, the condensation can also be performed in organic solvent, such as anhydrous petroleum ether. In contrast to the salt effect in aqueous solution, the addition of salt (LiCl, LiClOa) into organic solvents (ethylene glycol, formamide, and DMSO) results in the decreasing of reaction rate. However, a few aldehydes were found not to form benzoin under the benzoin condensation condition instead ethylenediol and ethanediol were formed. This condensation when catalyzed by cyanide ion, is assumed... [Pg.331]

Ethylene glycol monoacetate is a colorless, odorless liquid and is structurally a primary alcohol and an ester. It is made by combining a dihydric alcohol and a manocarbaxylic acid. It will mix completely with water and many of the lacquer solvents. Ethylene glycol manoocetate will dissolve cellulose esters and ethers and many of the resins. [Pg.826]

Figure 11 shows the variation of surface tension of 15 wt% HCl with mutual solvent (ethylene glycol monobutylether, EGMBE) concentration. The surface tension decreases with mutual solvent concentration up to 10 wt%, then remains constant. Mutual solvent acts as a surface-active species. A similar behavior was noted by D Angelo and Santucci [63] when mutual solvent was added to distilled water. [Pg.342]
