  2. Nonylphenol - Wikipedia

    en.wikipedia.org/wiki/Nonylphenol

    A branched nonylphenol, 4-nonylphenol, is the most widely produced and marketed nonylphenol. [12] The mixture of nonylphenol isomers is a pale yellow liquid, although the pure compounds are colorless. The nonylphenols are moderately soluble in water [12] but soluble in alcohol.

  3. Alkylphenol - Wikipedia

    en.wikipedia.org/wiki/Alkylphenol

    Alkylphenol. Alkylphenols are a family of organic compounds obtained by the alkylation of phenols. The term is usually reserved for commercially important propylphenol, butylphenol, amylphenol, heptylphenol, octylphenol, nonylphenol, dodecylphenol and related "long chain alkylphenols" (LCAPs). Methylphenols and ethylphenols are also ...

  4. Triton X-100 - Wikipedia

    en.wikipedia.org/wiki/Triton_X-100

    Triton X-100 (C. 14H. 22O (C. 2H. 4O)n) is a nonionic surfactant that has a hydrophilic polyethylene oxide chain (on average it has 9.5 ethylene oxide units) and an aromatic hydrocarbon lipophilic or hydrophobic group. The hydrocarbon group is a 4- (1,1,3,3-tetramethylbutyl)- phenyl group. Triton X-100 is closely related to IGEPAL CA-630, which ...

  5. Phenol formaldehyde resin - Wikipedia

    en.wikipedia.org/wiki/Phenol_formaldehyde_resin

    The negative charge is delocalised over the aromatic ring, activating sites 2, 4 and 6, which then react with the formaldehyde. Being thermosets, hydroxymethyl phenols will crosslink on heating to around 120 °C to form methylene and methyl ether bridges through the elimination of water molecules. At this point the resin is a 3-dimensional ...

  6. Ethoxylation - Wikipedia

    en.wikipedia.org/wiki/Ethoxylation

    Ethoxylation. In organic chemistry, ethoxylation is a chemical reaction in which ethylene oxide (C2H4O) 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 (OC2H4)nOH, where n ranges from 1 to 10.

  7. Phenols - Wikipedia

    en.wikipedia.org/wiki/Phenols

    Phenols. In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of one or more hydroxyl groups (− O H) bonded directly to an aromatic hydrocarbon group. [1] The simplest is phenol, C. 6H. 5OH.

  8. Phenol - Wikipedia

    en.wikipedia.org/wiki/Phenol

    Phenol is a component in liquid–liquid phenol–chloroform extraction technique used in molecular biology for obtaining nucleic acids from tissues or cell culture samples. Depending on the pH of the solution either DNA or RNA can be extracted. Phenol is so inexpensive that it also attracts many small-scale uses.

  9. NP-40 - Wikipedia

    en.wikipedia.org/wiki/NP-40

    NP-40 (also known as Tergitol-type NP-40 and nonyl phenoxypolyethoxylethanol [1]) is a commercially available detergent with CAS Registry Number 9016-45-9. NP-40 is an ethoxylated nonylphenol for non-ionic surfactants and can act as emulsifier and demulsifier agent. NP-40 is often used to break open all membranes within a cell, including the ...
