Mineral oil is the name given to light mixtures of higher alkanes, obtained from the distillation of petroleum. It is also known as liquid paraffin or pariffinum liquidum, white oil and liquid petroleum.
Mineral oil has little reactivity.
Mineral oil is colorless, odorless, viscous liquid. It is insoluble in water, but miscible with many organic solvents. It has a density of around 0.85 g/cm3, depending on the type of oil (light or heavy). It has a flash point of 168.33°C.
Mineral oil is available as baby oil, either pure or with perfume. The latter should be removed before using the oil in experiments.
It is also sometimes available as camp fuel. Some lamp and torch oils are 100% mineral oil.
Beekeeping suppliers will also sell mineral oil (labelled paraffin oil), used for the treatment of honey bee mites. It has good purity and generally lacks additives.
Mineral oil is best bought than made, as it's very cheap.
- Store alkali metals
- Make an oil bath
- Make sodium metal
Mineral oil poses little risk, but untreated mineral oil is considered hazardous. It is generally not flammable at room temperature, needs prior heating to ignite. Ingestion of mineral oil will lead to diarrhea, as oils are laxative.
Mineral oil should be kept in closed bottles. As it is not volatile, you can use any clean bottle.
No special disposal is required. Should be disposed like any other oil.
