Recrystallization is a method used to purify chemicals by dissolving a mixture of a compound and its impurities, in an appropriate solvent, prior to heating the solution. [1]
Neutral spirit is legally defined as spirit distilled from any material distilled at or above 95% ABV (190 US proof) and bottled at or above 40% ABV. [5] When the term is used in an informal context rather than as a term of U.S. law, any distilled spirit of high alcohol purity (e.g., 170 proof or higher) that does not contain added flavoring may be referred to as neutral alcohol.

Flambé is a technique where alcohol, such as brandy, is poured on top of a dish and then ignited to create a visual presentation. [3]A variation of the flambé tradition is employed in Japanese teppanyaki restaurants where a spirit is poured onto the griddle and then lit, providing both a dramatic start to the cooking, and a residue on the griddle which indicates to the chef which parts of ...

Mixing solvents creates cooling baths with variable freezing points. Temperatures between approximately −78 °C and −17 °C can be maintained by placing coolant into a mixture of ethylene glycol and ethanol, [1] while mixtures of methanol and water span the −128 °C to 0 °C temperature range.
These species are chemically inert, which allows the salt to serve as an inert electrolyte over a wide potential range. Given the sensitivity of electrochemical experiments, this salt is usually further purified, e.g., by recrystallization from aqueous or absolute ethanol. [1]
