No ill effects appear to be produced by limited exposure to hydrocarbon solvent vapour, but a higher degree of exposure may cause symptoms such as headaches and nausea, which disappear as soon as exposure ceases.

"' Benzyl potassium "'is an organopotassium compound with the formula C 6 H 5 CH 2 K . It is an orange solid that is so extremely basic that it is compatible only with hydrocarbon solvents.
23.
Due to concerns over atmospheric pollution and hazardous waste disposal, the electronics industry has been gradually shifting from rosin flux to water-soluble flux, which can be removed with deionized water and detergent, instead of hydrocarbon solvents.
24.
The study of 990 Parkinson's patients found that those exposed to hydrocarbon solvents found in common petroleum-based products such as paints and glues were an average of three years younger at the first sign of disease symptoms.

In 1987, a research group led by Dr . Kenneth S . Suslick, a chemist at the University of Illinois in Champaign-Urbana, created clouds of sonoluminescent bubbles in a bath of liquid dodecane, a hydrocarbon solvent similar to gasoline.

Vapor Extraction Process ( VAPEX ) is an " in situ " technology, similar to SAGD . Instead of steam, hydrocarbon solvents are injected into an upper well to dilute bitumen and enables the diluted bitumen to flow into a lower well.
27.
An organic solvent composed of 30 % tributyl phosphate ( TBP ) in a hydrocarbon solvent, such as kerosene, is used to extract the uranium as UO 2 ( NO 3 ) 2 ?TBP complexes, and plutonium as similar complexes, from other fission products, which remain in the aqueous phase.
28.
Since kauri resin is readily soluble in butyl alcohol but not in most hydrocarbon solvents, the resin solution will tolerate only a certain amount of dilution . " Stronger " solvents such as benzene can be added in a greater amount ( and thus have a higher Kb value ) than " weaker " solvents like mineral spirits.
29.
Common enhanced methods include the use of stripping gas, the use of a vacuum system ( lowering the entire stripper pressure ), the DRIZO process, which is similar to the use of stripping gas but uses a recoverable hydrocarbon solvent, and the Coldfinger process where the vapors in the reboiler are partially condensed and drawn out separately from the bulk liquid.
