  2. Synthetic oil - Wikipedia

    en.wikipedia.org/wiki/Synthetic_oil

    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.

  3. Polyolester - Wikipedia

    en.wikipedia.org/wiki/Polyolester

    Polyolester oil (POE oil) is a type of wax-free synthetic oils used in refrigeration compressors that is compatible with the refrigerants R-134a, R-410A, and R-12. [1] POE oils are used as a lubricant in systems using the refrigerant HFC-134a when replacing CFC-12 , as these systems traditionally use mineral oil , [ 2 ] which HFC-134a does not ...

  4. List of esters - Wikipedia

    en.wikipedia.org/wiki/List_of_esters

    An ester of carboxylic acid. R stands for any group (organic or inorganic) and R′ stands for organyl group. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).

  5. Ester - Wikipedia

    en.wikipedia.org/wiki/Ester

    An ester of a carboxylic acid. R stands for any group (typically hydrogen or organyl) and R ′ stands for any organyl group. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (R ′).

  6. Types of plant oils - Wikipedia

    en.wikipedia.org/wiki/Types_of_plant_oils

    A press developed at MIT's D-Lab, for example, is capable of exerting 800–1,000psi to extract peanut oil. [2] Industrial machines for extracting oil mechanically are call expellers. Many expellers add heat and pressure, in order to increase the amount of oil extracted. If the temperature does not exceed 120 °F, the oil can be called "cold ...

  7. Natural oil polyols - Wikipedia

    en.wikipedia.org/wiki/Natural_oil_polyols

    Differences and modifications in the process regime and reaction conditions used to make a given NOP also generally lead to different chemical architectures and therefore different end use performance of that NOP; so that even though two NOPs may have been made from the same Natural Oil root, they may be surprisingly different when used and ...

  8. Is There a Difference Between Canola and Vegetable Oil?

    Canola oil and vegetable oil are both neutral-flavored oils that can be used for a wide range of kitchen tasks. We discuss the difference and when to use both.

  9. Polypropylene glycol - Wikipedia

    en.wikipedia.org/wiki/Polypropylene_glycol

    Chemically it is a polyether, and, more generally speaking, it's a polyalkylene glycol (PAG) H S Code 3907.2000. The term polypropylene glycol or PPG is reserved for polymer of low- to medium-range molar mass when the nature of the end-group , which is usually a hydroxyl group, still matters.
