An oil is any nonpolar chemical substance that is composed primarily of hydrocarbons and is hydrophobic (does not mix with water) and lipophilic (mixes with other oils).
Amateur use of mineral oil follows industrial use, since it typically is the insulating and cooling fluid in large electrical transformers and similar equipment, such as small switches used for high-voltages. Mineral oil is used as a brake fluid in some cars, such as Citroën models with hydrodynamic suspension, and bicycle disc brakes.
It is an odorless, colorless oil, although commercial samples may be yellowish due to the presence of impurities. In chemical terms, oleic acid is classified as a monounsaturated omega-9 fatty acid , abbreviated with a lipid number of 18:1 cis -9, and a main product of Δ9-desaturase . [ 2 ]
Petroleum play (or "play"): A group of oil prospects that are controlled by the same set of geological circumstances. Pig: A device inserted into a pipeline for cleaning purposes. The act of using a pig is called pigging. Piston corers: Advanced piston corer, extended core barrel systems [clarification needed]
Naphtha (/ ˈ n æ f θ ə /, recorded as less common or nonstandard [1] in all dictionaries: / ˈ n æ p θ ə /) is a flammable liquid hydrocarbon mixture.Generally, it is a fraction of crude oil, but it can also be produced from natural-gas condensates, petroleum distillates, and the fractional distillation of coal tar and peat.
Spearmint essential oil has had success as a larvicide against mosquitoes. Using spearmint as a larvicide would be a greener alternative to synthetic insecticides due to their toxicity and negative effect to the environment. [31] Used as a fumigant, spearmint essential oil is an effective insecticide against adult moths. [32]
A sample of synthetic motor oil Synthetic oil is a lubricant consisting of chemical compounds that are artificially modified or synthesised. Synthetic oil is used as a substitute for petroleum-refined oils when operating in extreme temperature, in metal stamping to provide environmental and other benefits, and to lubricate pendulum clocks .
Linseed oil is an edible oil in demand as a dietary supplement, as a source of α-linolenic acid, an omega-3 fatty acid. In parts of Europe, it is traditionally eaten with potatoes and quark. [citation needed] Food-grade flaxseed oil is cold-pressed, obtained without solvent extraction, in the absence of oxygen, and marketed as edible flaxseed oil.
