Bromoethane, also known as ethyl bromide, is a chemical compound of the haloalkanes group. It is abbreviated by chemists as EtBr (which is also used as an abbreviation for ethidium bromide ). This volatile compound has an ether-like odor.
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.
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] EtBr + Mg → EtMgBr
(However, PE only dissolves at temperatures well above 100 °C.) Poly(styrene) has a solubility parameter of 9.1 cal 1/2 cm −3/2, and thus ethyl acetate is likely to be a good solvent. Nylon 6,6 has a solubility parameter of 13.7 cal 1/2 cm −3/2, and ethanol is likely to be the best solvent of those tabulated. However, the latter is polar ...
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure.
Dibromomethane or methylene bromide, or methylene dibromide is a halomethane with the formula CH 2 Br 2. It is slightly soluble in water but very soluble in organic solvents . It is a colorless liquid.
2. Not refrigerating your cookie dough. It might be tempting to get your cookies into the oven as soon as possible so you can, well, eat them sooner. However, ...
2 CH 3 MgX + 2 dioxane ⇌ (CH 3) 2 Mg + MgX 2 (μ-dioxane) 2 ↓. In such procedures, the dimethylmagnesium exists as the ether adduct, not the polymer. [4] 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 ...
