solvent mixture

Rate retardation relative to water was observed in all solvent mixtures studied.

Prepare standards of suitable concentrations in the same solvent mixture as in 4.1.

For example, ethanol/water solvent mixtures give rate constants 10-fold higher than sulfolane.

Chemical dispersant, a surfactant and solvent mixture, was applied to the slick.

For example, the standard state of water:dioxane 9:1 is precisely that solvent mixture, with no added solutes.

The sample is dissolved in a suitable solvent mixture; say a hydrocarbon and an alcohol which also must contain a small amount of water.

Relative to traditional cooling baths, solvent mixtures are adaptable for a wide temperature range.

The Grunwald-Winstein equation cannot fit all data for different kinds of solvent mixtures.

A simplified technique with test results is presented for use in particular with cryoscopic solvent mixtures.

This interesting result compares well with previous data reported by Murto for the solvolysis of 2,4-dinitrofluorobenzene in the same solvent mixtures.

A powerful (but generally toxic) solvent or solvent mixture must be used to remove the graffiti.

Determining the best gradient program, column length, pH, solvent mixture, or other experimental conditions has never been so easy!

A sample is dissolved in a solvent mixture of Toluene/ Propan-2-ol with 0.5% deionised water.

As an example of the latter The reaction proceeds at room temperature, with 1 mole% catalyst loading in an acetonitrile-water solvent mixture.

It can contain some black copal but it is still perfectly and easily dissolved in alcohol solvent mixtures.

The reactivity is enhanced, first slowly, and then more rapidly, by increasing the concentration of tert-bulyl alcohol in the solvent mixtures.

Painted objects must be cleaned with polar/non polar solvents or solvent mixtures.

This solvent mixture is non-flammable in the closed space of the reservoir and has a flash point of 100 F. when fully exposed to air.

The use of toluene and xylene to blend paint solvent mixtures is an example of processing without changes in chemical form.

Experimental conductivity data were analysed using the Fuoss–Hsia equation, and the chosen salt was found to associate to a certain extent in these solvent mixtures.

No long lived complexes are observed in solvent mixtures of water or methanol with ethanenitrile or propanone.

The compound is stable in a THF/ethylbenzene solvent mixture and commercially available as such.

To stabilise these almost hollow structures a resin and solvent mixture was painstakingly injected into the holes with a hypodermic needle.

A reversed-phase column allowed direct injection of extracts prepared in the conventional manner (90% acetone or other solvent mixtures containing water).

Solvent mixtures of cyclohexane and ethanol gave spectra which were very sensitive to the mole fraction of alcohol in the range 0–1%.
