  2. Recrystallization (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Recrystallization_(chemistry)

    However, a second solvent is allowed to evaporate from one container into a container holding the compound solution (gas diffusion). As the solvent composition changes due to an increase in the solvent that has gas diffused into the solution, the compound becomes increasingly insoluble in the solution and crystallizes.

    en.wikipedia.org/wiki/Aseptic_processing

    Aseptic processing was derived from Olin Ball's heat-cool-fill (HCF) machine that was developed in 1927. [5] While HCF was successful in improving the sensory quality of the processed chocolate milk as compared to canned product, the use of the equipment was hindered by its cost, maintenance, and inflexibility to process various container sizes, rendering the machine a failure.

  7. Ethoxylation - Wikipedia

    en.wikipedia.org/wiki/Ethoxylation

    Typically 5-10 units of ethylene oxide are added to each alcohol, [7] however ethoxylated alcohols can be more prone to ethoxylation than the starting alcohol, making the reaction difficult to control and leading to the formation of a product with varying repeat unit length (the value of n in the equation above).

  8. Recrystallization (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/Recrystallization_(metallurgy)

    Variation of recrystallized volume fraction with time. Recrystallization kinetics are commonly observed to follow the profile shown. There is an initial 'nucleation period' t 0 where the nuclei form, and then begin to grow at a constant rate consuming the deformed matrix. Although the process does not strictly follow classical nucleation theory ...

  9. Chafing fuel - Wikipedia

    en.wikipedia.org/wiki/Chafing_fuel

    Chafing fuel is a fuel used for heating food, typically placed under a chafing dish. [1] It is usually sold in a small canister and burned directly within that canister, with or without a wick. [1] The fuel often contains methanol, ethanol, or diethylene glycol, as these may be burned safely indoors, and produce minimal soot or odour.
