The experimentally determined optimum composition of the mixtures occurs at an acetone mass fraction of 75%. The trend of concentration varying with mixture compositions could be well predicated by the model, which relates the concentration to the mixing enthalpy within the scope of HSP theory. The...
By the mid-1960s, however, that mixture reached its boiling point when poor urban blacks pushed back against the presence of police brutality in their neighborhoods. Many of the urban riots of the era were, in fact, touched off ... DF Tibbs - Palgrave Macmillan US 被引量: 1发表: 2012...
Acetone (0.50 mL) as disperser solvent containing 20.0 μ L carbon disulfide (extraction solvent) was rapidly injected into the sample solution using a 0.50-mL syringe (gas-tight; Hamilton, USA). A cloudy water–acetone–carbon disulfide mixture was formed in the test tube. The ...

The APX enzyme activity was measured at 290 nm for 1 min. Using 1.95 ml of the reaction mixture that contained (50 mM phosphate buffer (pH 6.0) + 0.1 mM EDTA + 0.5 mM ascorbate + 1.0 mM H2O2 + 65 ml enzyme extract). The reaction was started by monitoring the degr...
Only the boiling temperature and liquid composition are specified for each experimental data point, as the vapour phase in equilibrium is constituted by pure acetone or pure water due to the negligible volatility of the ILs at the experimental conditions of pressure and temperature investigated. This...
This means that the clay will have to adsorb essentially all of the pore water, even in the 5% sand-bentonite mixture. However, not all of this water was tightly bound to the mineral surfaces. Assuming that the bentonite reduces the dielectric constant of the first three monolayers of water...
Acetone (0.50 mL) as disperser solvent containing 20.0 μL carbon disulfide (extraction solvent) was rapidly injected into the sample solution using a 0.50-mL syringe (gas-tight; Hamilton, USA). A cloudy water–acetone–carbon disulfide mixture was formed in the test tube. The mixture ...
(3) the organic solvents can weaken the interactions between dyes and HL-HBPs. Following these principles, a series of organic solvents with low boiling point and varied polarity can be used, such as ACN, ethanol, EA, TCM,n-hexane, tetrahydrofuran (THF), methanol, acetone, dichloromethane (...
To dissolve the monomers thoroughly, the mixture can be heated to an elevated temperature up to the boiling point of water i.e. 100° C. The polyvinyl monomer to be used in both embodiments of the invention should be miscible with or soluble in water so that the monomer will be ...
