  3. Electrospinning - Wikipedia

    en.wikipedia.org/wiki/Electrospinning

    Affects the traveling time of the polymer jet; should be high enough to allow complete evaporation of the solvent. Voltage, Feed rate: Feed rate: Determines the amount of solution available per unit of time. Influences the jet velocity and the material transfer rate. Increasing the rate causes more polymer to be processed at a given instant ...

  4. Centrifugal evaporator - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_evaporator

    If only one sample required evaporation then a rotary evaporator is most often used. The most advanced modern centrifugal evaporators not only concentrate many samples at the same time, they eliminate solvent bumping and can handle solvents with boiling points of up to 220 °C. This is more than adequate for the modern high throughput laboratory.

  5. Circulation evaporator - Wikipedia

    en.wikipedia.org/wiki/Circulation_evaporator

    Evaporation is the elimination of the solvent in form of vapor from a solution. For most evaporation systems, the solvent is water and the heat is provided by steam condensation. [ 4 ] In a forced circulation evaporation liquid is constantly circulated through the system.

    The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure.

  7. Dimethyl carbonate - Wikipedia

    en.wikipedia.org/wiki/Dimethyl_carbonate

    Dimethyl carbonate has an ester- or alcohol-like odor, which is more favorable to users than most hydrocarbon solvents it replaces. Dimethyl carbonate has an evaporation rate of 3.22 (butyl acetate = 1.0), which slightly slower than MEK (3.8) and ethyl acetate (4.1), and faster than toluene (2.0) and isopropanol (1.7).

  8. Butanone - Wikipedia

    en.wikipedia.org/wiki/Butanone

    Butanone is an effective and common solvent [8] and is used in processes involving gums, resins, cellulose acetate and nitrocellulose coatings and in vinyl films. [11] For this reason it finds use in the manufacture of plastics, textiles, in the production of paraffin wax , and in household products such as lacquer , varnishes , paint remover ...

  9. Vapor pressure - Wikipedia

    en.wikipedia.org/wiki/Vapor_pressure

    Although the relation between vapor pressure and temperature is non-linear, the chart uses a logarithmic vertical axis to produce slightly curved lines, so one chart can graph many liquids. A nearly straight line is obtained when the logarithm of the vapor pressure is plotted against 1/(T + 230) [8] where T is the temperature in degrees Celsius ...
