A solvent is a substance, most often a liquid, that can dissolve other substances. Here, the substance being dissolved is called a solute. When a solvent and a solute combine, they form a solution - a homogenous mixture of both the solvent and the solute. Water is a universal biological solvent. Its polar structure allows it to dissolve many other polar compounds. The ability of water to dissolve is governed by a balance between water molecules binding to each other and binding to the solute. A...

Rotary Evaporation to Remove Solvent

Source: Dr. Melanie Pribisko Yen and Grace Tang — California Institute of Technology Rotary evaporation is a technique most commonly used in organic chemistry to remove a solvent from a higher-boiling point compound of interest. The rotary evaporator, or "rotovap", was invented in 1950 by the chemist Lyman C. Craig. The primary use of a rotovap is to dry and purify samples for downstream applications. Its speed and ability to handle large volumes of solvent make rotary evaporation a preferred...

Source: Hsin-Chun Chiu and Tyler J. Morin, laboratory of Dr. Ian Tonks—University of Minnesota Twin Cities Schlenk lines and high vacuum lines are both used to exclude moisture and oxygen from reactions by running reactions under a slight overpressure of inert gas (usually N2 or Ar) or under vacuum. Vacuum transfer has been developed as a method separate solvents (other volatile reagents) from drying agents (or other nonvolatile agents) and dispense them to reaction or storage vessels while...

A new way for the production of biopolymer-based aerogels by carbon dioxide (CO2) induced gelation is shown. The technique utilizes pressurized carbon dioxide (5 MPa) for the production of biopolymer hydrogels and supercritical CO2 (12 MPa) to convert gels into aerogels. The only solvents needed besides CO2 are water and ethanol.

Titration in Nonaqueous Solvents

Most acid-base titrations are performed in an aqueous medium. In aqueous titrations, water competes with weaker acids or bases for proton donation or acceptance, leading to ambiguous endpoints in the titration curve. Water also affects the partial ionization of weak acids or bases. For example, water accepts a proton from acetic acid to form hydronium and acetate ions. The hydronium ion formed is a stronger acid than acetic acid, and the acetate ion is a stronger base than water. As a result,...
FAQs
Benzene’s six-carbon ring contains delocalized pi electrons, but the molecule remains low in polarity overall. As a result, its interactions with dissolved substances rely mainly on dispersion and other weak intermolecular forces rather than strong polarity-driven interactions. This electronic structure helps explain why benzene is most compatible with nonpolar or weakly polar materials in chemical systems.
Materials with low or modest polarity are generally the best candidates for dissolution in benzene solvent. Their compatibility reflects the absence of strong polarity requirements and the ability of benzene to provide dispersion-based interactions. This behavior is important when interpreting whether a compound will remain in a solvent phase during laboratory extraction or other organic-chemistry operations.
Benzene shares solvent-use roles with toluene, heptane, and cyclohexane, but the overview identifies these substances as safer alternatives when they are suitable for the task. The comparison therefore involves more than dissolving ability: solvent selection must also consider benzene’s volatility, flammability, and established carcinogenicity alongside the chemical requirements of the process.
These properties make safety a central part of any decision to use benzene. High volatility can increase the presence of benzene in the surrounding environment, while flammability creates a fire concern and established carcinogenicity adds a serious health consideration. Consequently, laboratories and industrial operations increasingly favor a suitable alternative rather than treating solvent performance as the only criterion.
In extraction, benzene can provide a liquid phase that dissolves compatible nonpolar or weakly polar substances. The resulting distribution between liquid phases helps researchers interpret phase separations and assess where a substance has moved during processing. Its use must be weighed against safety concerns, so a safer solvent may be selected when it can provide the needed separation.
Benzene has been used as a medium for chemical reactions and in industrial processes connected with chemical manufacture. In these settings, its solvent behavior can support contact between compatible reactants or help process dissolved materials. Modern decisions require balancing that established usefulness with volatility, flammability, and carcinogenicity, which have encouraged substitution by safer options when appropriate.
