“solvent”的概念、定义、翻译、参考文献-科学参考

solvent

Physics

A liquid that dissolves another substance or substances to form a solution. Polar solvents are compounds such as water and liquid ammonia, which have dipole moments and consequently high dielectric constants. These solvents are capable of dissolving ionic compounds or covalent compounds that ionize (see solvation). Nonpolar solvents are compounds such as ethoxyethane and benzene, which do not have permanent dipole moments. These do not dissolve ionic compounds but will dissolve nonpolar covalent compounds.

Chemistry

A liquid that dissolves another substance or substances to form a solution. Polar solvents are compounds such as water and liquid ammonia, which have dipole moments and consequently high dielectric constants. These solvents are capable of dissolving ionic compounds or covalent compounds that ionize (see solvation). Nonpolar solvents are compounds such as ethoxyethane and benzene, which do not have permanent dipole moments. These do not dissolve ionic compounds but will dissolve nonpolar covalent compounds. Solvents can be further categorized according to their proton-donating and accepting properties. Amphiprotic solvents self-ionize and can therefore act both as proton donators and acceptors. A typical example is water:
${2H}_{2} O ⇌ H_{3} O^{+} {+ OH}^{-}$
Aprotic solvents neither accept nor donate protons; tetrachloromethane (carbon tetrachloride) is an example.

Chemical Engineering

The liquid part of a solution in dissolving another substance or substances. Water is a commonly used solvent. Being polar, water is capable of dissolving ionic compounds or covalent compounds that ionize. Non-polar solvents, such as benzene, do not dissolve ionic compounds but will dissolve non-polar covalent compounds. In alloys, the solvent is taken as the major component in the solid solution.

Biology

A liquid that dissolves another substance or substances to form a solution. Polar solvents are compounds, such as water, in which there is some separation of charge in the chemical bonds. These solvents are capable of dissolving ionic compounds or covalent compounds that ionize. Nonpolar solvents are compounds, such as benzene, that do not dissolve ionic compounds but will dissolve nonpolar covalent compounds.
