  2. Photochlorination - Wikipedia

    en.wikipedia.org/wiki/Photochlorination

    An example of photochlorination at low temperatures and under ambient pressure is the chlorination of chloromethane to dichloromethane. The liquefied chloromethane (boiling point -24 °C) is mixed with chlorine in the dark and then irradiated with a mercury-vapor lamp. The resulting dichloromethane has a boiling point of 41 °C and is later ...

  5. Dichloromethane - Wikipedia

    en.wikipedia.org/wiki/Dichloromethane

    DCM is produced by treating either chloromethane or methane with chlorine gas at 400–500 °C. At these temperatures, both methane and chloromethane undergo a series of reactions producing progressively more chlorinated products. In this way, an estimated 400,000 tons were produced in the US, Europe, and Japan in 1993. [12] CH 4 + Cl 2 → CH ...

  6. Ebulliometer - Wikipedia

    en.wikipedia.org/wiki/Ebulliometer

    Ebulliometer of Świętosławski. In physics, an ebulliometer (from Latin ēbullīre 'to boil') is an instrument designed to accurately measure the boiling point of liquids by measuring the temperature of the vapor–liquid equilibrium either isobarically (at constant pressure) or isothermally (at constant temperature).

  7. Zeotropic mixture - Wikipedia

    en.wikipedia.org/wiki/Zeotropic_mixture

    A larger gap between the boiling points creates a larger temperature glide between the boiling curve and dew curve at a given mass fraction. [4] However, with any zeotropic mixture, the temperature glide decreases when the mass fraction of a component approaches 1 or 0 (i.e. when the mixture is almost separated into its pure components) because ...
