Equivolume mixture

After 2 hours the mixture is cooled to about 0°C and the crude product Is collected by filtration, washed with diethyl ether and dried in a vacuum oven. After treatment with decolorizing charcoal and recrystallization from an equivolume mixture of isopropanol and methanol, the product, 2,5-bis(2,2,2-trifluoroethoxy)-N-(2-piperidylmethyl)benzamide hydrochloride has a MP of 228°C to 229°C. [Pg.644]

The HRP-catalyzed polymerization of (-l-)-catechin was carried out in an equivolume mixture of 1,4-dioxane and buffer (pH 7) to give the polymer with molecular weight of 3.0 x 10 in 30% yield. Using methanol as co-solvent improved the polymer yield and molecular weight. In the polymerization of... [Pg.240]

Into a Schlenk tube was placed Auf 1,5-cyclooctadiene)-nickeI(0) (2.6 mmol), 2,2 -bipyridyl (2.6mmol), 1,5-cyclooctadiene (0.2ml), DMF (4ml), and toluene (8 ml). The reaction mixture was heated to 80°C for 0.5 h under argon. The dibromide comonomers 623 and 634 dissolved in degassed toluene (8 ml molar ratio of dibromides to nickel complex 0.65) were added under argon to the DMF-toluene solution and the polymerization maintained at 80°C for 3 days in the dark. 2-Bromofluorene (molar ratio of dibromides to monobromide 0.1) dissolved in degassed toluene (1ml) was added and the reaction continued for 12 h. The polymers were precipitated by addition of the hot solution dropwise to an equivolume mixture of concentrated HC1, methanol, and acetone. The isolated polymers were then dissolved in toluene or dichlor-omethane and reprecipitated with methanol/acetone (1 1). The copolymers were dried at 80°C in vacuo. The isolated yields of copolymers 240a-c were 79-85%. [Pg.255]

Three grams of oxalic add 2-hydrate are dissolved in 30ml of an equivolume mixture of water and ethanoL The solution is cooled and 6g of aquopentamminechromium (III) nitrate (No. 112) are stirred in. The mixture is continually stirred for 5 minutes on the steam bath the orange solid changes to a reddish tint during this time. The prod-... [Pg.225]

Two and one-half grams of oxalatobromidc <126 d) are allowed to stand for 24 hours with 10-15ml of concentrated hydrobromic add shake occasionally. An equivolume mixture of alcohol and ether is added to the red-violet mixture until precipitation is complete the entire mixture is cooled in ice, The reddish solid is washed with 95% alcohol and with ether, and then dried in air. [Pg.229]

The we/a-photocycloadducts 9 and 10 were prepared in > 5 g quantities by 24-hour irradiation at 254 nm of an equivolume mixture of the aromatic compound and alkene contained in four 50 X 1-cm silica tubes. [Pg.992]

Peroxidase (CiP) oxidatively polymerized cardol, a major component of CNSL [105]. The efficient polymer production was achieved in an equivolume mixture... [Pg.178]

Peroxidase-catalyzed polymerization of various flavonoids was investigated in an equivolume mixture of 1,4-dioxane and pH 8 buffer [110]. Flavonols (quercetin) as well as isoflavones (diadzein and 5,6,4 -trihydroxyisoflavone) were subjected to the enzymatic oxidative polymerization to produce the flavonoid polymers. From diadzein, the polymer soluble in DMF and DMSO was formed in a high yield. [Pg.181]

Catalyst samples were ground into fine powder, freed of moisture, and sealed in glass bulbs, which were ultimately broken within a Dewar-flask calorimeter. A heater, Beckmann thermometer, sample holder, and stirrer were introduced into the calorimeter through an evacuated lid. The dissolutions were carried out at 160° in equivolume mixtures of H2SO4 and H3PO4. The calorimeter constant was reproducible within 0.05% the over-all precision of the determinations is estimated to be within 1 cal./g. [Pg.257]

Thus, permittivity of equivolume mixture of two chemically non-interacting solvents can be calculated from the equation... [Pg.514]

A water-soluble rutin derivative consisting of A and B (20 80 mol %, Fig. 6) is a commercially available product. This derivative was also polymerized by the laccase catalyst the laccase-catalyzed polymerization in an equivolume mixture of methanol and acetate buffer produced a polymer with molecular weight of 1 x 10" in a high yield. [Pg.59]
