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.
Acetone (2-propanone or dimethyl ketone) is an organic compound with the formula (CH 3) 2 CO. [22] It is the simplest and smallest ketone (R−C(=O)−R').It is a colorless, highly volatile, and flammable liquid with a characteristic pungent odour, very reminiscent of the smell of pear drops.
Vapor pressure of acetone based on formula, ... Vapor-liquid Equilibrium of Acetone/water [4] P = 760 mmHg BP Temp. °C % by mole acetone liquid vapor 100.00: 0.0: 0.0
The threshold value is the concentration at which an aroma or taste can be detected (air, water and fat). The recognition threshold or arousal threshold of olfactory neurons is the concentration at which you can identify an odor (air, water and fat). The odour activity value is the concentration divided by the threshold.
Acetone and acetic anhydride ((CH 3 C(O)) 2 O) upon the addition of boron trifluoride (BF 3) catalyst: [11] (CH 3 C(O)) 2 O + CH 3 C(O)CH 3 → CH 3 C(O)CH 2 C(O)CH 3 A second synthesis involves the base-catalyzed condensation (e.g., by sodium ethoxide CH 3 CH 2 O − Na + ) of acetone and ethyl acetate , followed by acidification of the sodium ...
At laboratory scale, MIBK can be produced via a three-step process using acetone as the starting material. Self-condensation , a type of aldol reaction , produces diacetone alcohol , [ 3 ] which readily dehydrates to give 4-methylpent-3-en-2-one (commonly, mesityl oxide ). [ 4 ]
Natural gas leaks happen nearly every day in the U.S. — and they can be deadly if they go undetected. A report from a group of Texas environmental nonprofits released in June found around 2,600 ...
Triethylamine is soluble in water to the extent of 112.4 g/L at 20 °C. [3] It is also miscible in common organic solvents, such as acetone, ethanol, and diethyl ether. Laboratory samples of triethylamine can be purified by distilling from calcium hydride .
