Heptane and its many isomers are widely used in laboratories as a non-polar solvent. [11] As a liquid, it is ideal for transport and storage.In the grease spot test, heptane is used to dissolve an oil spot to show the previous presence of organic compounds on a stained paper.

Nonpolar solvent A / solvent B / polymer soluble in solvent B and water / salt / water e.g. 10.9% heptane, 15.5% dichloromethane, 7.1% polyethylene oxide, 66.5% sodium sulfate (> 0.1%) in water; Nonpolar solvent / Polar solvent / salt / water / Fluorinated solvent e.g. Hexane, isopropanol, brine, perfluoromethylcyclohexane; Non polar solvent ...
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Being an alkane, 2-methylhexane is insoluble in water, but is soluble in many organic solvents, such as alcohols and ether. However, 2-methylhexane is more commonly considered as a solvent itself. Therefore, even though it is present in many commercially available heptane products, it is not considered as a destructive impurity, as heptane is ...
A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid. Water is a solvent for polar molecules, and the most common solvent used by living things; all the ions and proteins in a cell are dissolved in water within the cell. Major uses of solvents are in paints, paint removers, inks, and dry cleaning. [2]
Since 1974, the United States Postal Service has issued self-adhesive stamps that some collectors find difficult to separate from envelopes via the traditional method of soaking in water. Heptane-based products, like Bestine, as well as limonene-based products, have become popular solvents for removing stamps more easily. [4]
