Xylene is used in the laboratory to make baths with dry ice to cool reaction vessels, [17] and as a solvent to remove synthetic immersion oil from the microscope objective in light microscopy. [18] In histology, xylene is the most widely used clearing agent. [19] Xylene is used to remove paraffin from dried microscope slides prior to staining.
Dihydrolevoglucosenone (Cyrene) is a bicyclic, chiral, seven-membered heterocyclic cycloalkanone which is a waste derived and fully biodegradable aprotic dipolar solvent. [4] [5] [6] It is an environmentally friendly alternative to dimethylformamide (DMF) and N-methyl-2-pyrrolidone (NMP). [7]

Green solvents are environmentally friendly chemical solvents that are used as a part of green chemistry.They came to prominence in 2015, when the UN defined a new sustainability-focused development plan based on 17 sustainable development goals, recognizing the need for green chemistry and green solvents for a more sustainable future.

Likewise, the para-xylene consumption showed unprecedented growth in 2010, growing by 2,800,000 tons, a full ten percent growth from 2009. [1] Toluene is also a valuable petrochemical for use as a solvent and intermediate in chemical manufacturing processes and as a high octane gasoline component. [2] [3] [4] [5]

Triton X-100 is soluble at 25 °C in water, toluene, xylene, trichloroethylene, ethylene glycol, ethyl ether, ethyl alcohol, isopropyl alcohol, and ethylene dichloride. Triton X-100 is insoluble in kerosene, mineral spirits, and naphtha, unless a coupling agent like oleic acid is used.
Unlike the other common ketone solvents, acetone and MEK, MIBK has quite low solubility in water, making it useful for liquid-liquid extraction.It has a similar polarity to ethyl acetate, but greater stability towards aqueous acid and base.
