  2. Dichloromethane - Wikipedia

    en.wikipedia.org/wiki/Dichloromethane

    DCM's volatility and ability to dissolve a wide range of organic compounds makes it a useful solvent for many chemical processes. [12] In the food industry, it is used to decaffeinate coffee and tea as well as to prepare extracts of hops and other flavourings.

  3. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    When comparing a polar and nonpolar molecule with similar molar masses, the polar molecule in general has a higher boiling point, because the dipole–dipole interaction between polar molecules results in stronger intermolecular attractions. One common form of polar interaction is the hydrogen bond, which is also

  4. Polar aprotic solvent - Wikipedia

    en.wikipedia.org/wiki/Polar_aprotic_solvent

    A polar aprotic solvent is a solvent that lacks an acidic proton and is polar. Such solvents lack hydroxyl and amine groups. In contrast to protic solvents, these solvents do not serve as proton donors in hydrogen bonding, although they can be proton acceptors. Many solvents, including chlorocarbons and hydrocarbons, are classifiable as aprotic ...

  5. Solvent - Wikipedia

    en.wikipedia.org/wiki/Solvent

    The following table shows that the intuitions from "non-polar", "polar aprotic" and "polar protic" are put numerically – the "polar" molecules have higher levels of δP and the protic solvents have higher levels of δH. Because numerical values are used, comparisons can be made rationally by comparing numbers.

  6. Carbon tetrachloride - Wikipedia

    en.wikipedia.org/wiki/Carbon_tetrachloride

    Because of this symmetric geometry, CCl 4 is non-polar. Methane gas has the same structure, making carbon tetrachloride a halomethane. As a solvent, it is well suited to dissolving other non-polar compounds such as fats and oils. It can also dissolve iodine.

  8. Organochlorine chemistry - Wikipedia

    en.wikipedia.org/wiki/Organochlorine_chemistry

    These solvents tend to be relatively non-polar; they are therefore immiscible with water and effective in cleaning applications such as degreasing and dry cleaning for their ability to dissolve oils and grease. They are mostly nonflammable or have very low flammability.
