Can methanol be miscible with mineral spirits?
Thread Content
Is methanol miscible with mineral spirits? Water and oil can separate into layers; will a mixture of methanol and mineral oil also form layers?
To determine whether two substances belong to the same category of organic compounds, if they are both organic compounds, they should be mutually soluble; otherwise, they will not be soluble.
Similar and compatible substances are definitely mutually soluble
It depends on the density of your solvent oil and the separation method you use; if you opt for liquid-liquid separation, the density difference between the solvent oil and methanol needs to be significant.
Agree with what was said on the 5th floor; they are definitely mutually soluble. The original poster can check it online
This mainly relates to solubility; you can refer to the (solvent compatibility table). Methanol is miscible with cyclohexane, cyclopentane, n-heptane, n-hexane, isooctane, and pentane. Solvent oils are generally in the C5-C12 range; therefore, it depends on the type of solvent oil you are referring to
Solvent oils can be divided into three types: alkanes, cycloalkanes, and aromatics. In fact, aside from a few pure hydrocarbon solvent oils such as ethane, toluene, and xylene, solvent oils are all mixtures of hydrocarbons with various structures. From a chemical composition perspective, they can be divided into alkanes, cycloalkanes, and aromatics, etc. The so-called 6#, 120#, and 200# solvents are, in fact, alkanes. Aromatic hydrocarbons refer to benzene, toluene, xylene, etc. Methanol is a colorless, transparent, flammable, and volatile toxic liquid that is non-corrosive to metals at room temperature (with the exception of lead and aluminum), and it has a slight alcohol-like odor. Molecular weight: 32.04; relative density: 0.792 (20/4°C); melting point: -97.8°C; boiling point: 64.5°C; heat of combustion: 725.76 KJ/mol; flash point: 12.22°C; autoignition temperature: 463.89°C; vapor density: 1.11; vapor pressure: 13.33 KPa (100 mmHg at 21.2°C); the lower and upper limits for the vapor-air mixture are 6–36.5% (by volume). It is miscible with water, ethanol, ether, benzene, toluene, halogenated hydrocarbons, and many other organic solvents. Therefore, methanol is miscible with solvent oil!
Reply to 9# liushijia: I have been working with solvent oil of type 6#, whose main component is hexane. It would be advisable to conduct a compatibility test through inspection services; the results show that its solubility in methanol is only around 10%, and a clear separation occurs between the oil and methanol Thank you
Many people upstairs probably haven’t checked the solvent manuals or aren’t majoring in chemistry; methanol and many alkane-based solvents are layered, as are petroleum ether and No. 120 mineral spirits
