The flame temperature of pure acetone is 1980 °C. [44] Like most ketones, acetone exhibits the keto–enol tautomerism in which the nominal keto structure (CH 3) 2 C=O of acetone itself is in equilibrium with the enol isomer (CH 3)C(OH)=(CH 2) (prop-1-en-2-ol). In acetone vapor at ambient temperature, only 2.4 × 10 −7 % of the molecules are ...

Petroleum jelly. Petroleum jelly, petrolatum, white petrolatum, soft paraffin, or multi-hydrocarbon, CAS number 8009-03-8, is a semi-solid mixture of hydrocarbons (with carbon numbers mainly higher than 25), [1] originally promoted as a topical ointment for its healing properties. [2] Vaseline has been an American brand of petroleum jelly since ...
It contains 87.5–91% by volume of absolute ethyl alcohol. The rest consists of water and the denaturants, with or without color additives, and perfume oils. Rubbing alcohol contains in each 100 ml more than 355 mg of sucrose octaacetate or more than 1.40 mg of denatonium benzoate. The preparation may be colored with one or more color additives.
Cooling bath. A typical experimental setup for an aldol reaction. Both flasks are submerged in a dry ice/acetone cooling bath (−78 °C) the temperature of which is being monitored by a thermocouple (the wire on the left). A cooling bath or ice bath, in laboratory chemistry practice, is a liquid mixture which is used to maintain low ...
Acetone peroxide (/ æ s ə ˈ t ə ʊ n p ɛr ˈ ɒ k s aɪ d / ⓘ also called APEX and mother of Satan [3] [4]) is an organic peroxide and a primary explosive. It is produced by the reaction of acetone and hydrogen peroxide to yield a mixture of linear monomer and cyclic dimer, trimer, and tetramer forms. The monomer is dimethyldioxirane.
Ibuprofen is practically insoluble in water, but very soluble in most organic solvents like ethanol (66.18 g/100 mL at 40 °C for 90% EtOH), methanol, acetone and dichloromethane. [60] The original synthesis of ibuprofen by the Boots Group started with the compound isobutylbenzene. The synthesis took six steps.
Acetone, commonly found as a fraction of nail polish remover (or at hardware stores in pure form), is a widely available solvent capable of softening cured cyanoacrylate. [36] Other solvents include nitromethane , dimethylformamide , [ 37 ] dimethyl sulfoxide , and methylene chloride . [ 38 ]
