This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

Ethylmagnesium bromide is commercially available, usually as a solution in diethyl ether or tetrahydrofuran. It may be prepared in the normal manner of Grignard reagents — by reacting bromoethane with magnesium in diethyl ether : [ 2 ]
Solubility in water. 1.067 g/100 mL (0 °C) 0.914 g/100 mL (20 °C) ... Bromoethane, also known as ethyl bromide, is a chemical compound of the haloalkanes group.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Who is Gunner Stockton? Here's what to know on Georgia's backup quarterback as he came in for injured Carson Beck in the second half vs. Texas:
Addition of 1,4-dioxane causes precipitation of solid MgX 2 (μ-dioxane) 2, a coordination polymer. [4] This precipitation drives the Schlenk equilibrium toward (CH 3) 2 Mg. Related methods have been applied to other dialkylmagnesium compounds. [3] Dimethylmagnesium can also be prepared by combining dimethylmercury and magnesium. [5] [6]
Earlier this week, the Wall Street Journal reported that raw Arabica coffee prices soared to a record high of nearly $3.44 per pound, which beat the prior record of $3.35 from 1977. Volcafe, a top ...
