  2. Ethoxylation - Wikipedia

    en.wikipedia.org/wiki/Ethoxylation

    In organic chemistry, ethoxylation is a chemical reaction in which ethylene oxide (C 2 H 4 O) adds to a substrate. It is the most widely practiced alkoxylation, which involves the addition of epoxides to substrates. In the usual application, alcohols and phenols are converted into R(OC 2 H 4) n OH, where n ranges from 1 to 10. Such compounds ...

  3. Alkoxylation - Wikipedia

    en.wikipedia.org/wiki/Alkoxylation

    The usual manifestation of this reaction is ethoxylation of alcohols (ROH), in which case ethylene oxide is the alkoxylating agent: ROH + C 2 H 4 O → ROCH 2 CH 2 OH. Another industrially significant epoxide is propylene oxide (PO, OCH 2 CHCH 3). PO is mainly used for alkoxylation to produce polyether polyols.

    Polysorbate 20 (common commercial brand names include Kolliphor PS 20, [2] Scattics, Alkest TW 20, Tween 20, and Kotilen-20) is a polysorbate-type nonionic surfactant formed by the ethoxylation of sorbitan monolaurate.

  6. Narrow-range ethoxylate - Wikipedia

    en.wikipedia.org/wiki/Narrow-range_ethoxylate

    Narrow-range ethoxylates (NREs) in chemistry are fatty alcohol polyglycol ethers with a narrow homolog distribution and are known nonionic surfactants.They can be produced industrially, for example, by the addition of ethylene oxide onto fatty alcohols in the presence of suitable catalysts (layer compounds which have been calcined or hydrophobized with fatty acids).

  7. Epoxide - Wikipedia

    en.wikipedia.org/wiki/Epoxide

    A generic epoxide. In organic chemistry, an epoxide is a cyclic ether, where the ether forms a three-atom ring: two atoms of carbon and one atom of oxygen.This triangular structure has substantial ring strain, making epoxides highly reactive, more so than other ethers.

  8. Putrefaction - Wikipedia

    en.wikipedia.org/wiki/Putrefaction

    Timeline of postmortem changes (stages of death), with putrefaction labeled near middle. The rough timeline of events during the putrefaction stage is as follows: 1–2 days: Pallor mortis, algor mortis, rigor mortis, and livor mortis are the first steps in the process of decomposition before the process of putrefaction.
