Nonylphenol is used in manufacturing antioxidants, lubricating oil additives, laundry and dish detergents, emulsifiers, and solubilizers. [2] It can also be used to produce tris(4-nonyl-phenyl) phosphite (TNPP), which is an antioxidant used to protect polymers, such as rubber, Vinyl polymers, polyolefins, and polystyrenics in addition to being ...
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 ...
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 ...
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 ...
But I am suspicious of everything that comes from the g*vernment (if you can't read Portuguese, the site describes commercial Nonylphenol, with 90% para-nonylphenol, 4% orto-nonylphenol and 5% 2,4-dinonylphenol; this may explain why the data differs slightly from de:Nonylphenol: Freezing point (Ponto de fusão -10 x Schmelzpunkt 2)
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 ...
Liebermann reagent. The Liebermann reagent named after Hungarian chemist Leo Liebermann (1852-1926) is used as a simple spot-test to presumptively identify alkaloids as well as other compounds. It is composed of a mixture of potassium nitrite and concentrated sulfuric acid. [ 1 ][ 2 ] 1 g of potassium nitrite is used for every 10 mL of sulfuric ...
C ratio of 1.12372%. [2] A related standard is the use of wood, which has a δ 13 C of -25‰, as the material for which radiocarbon ages are calibrated. Since different materials have different δ 13 C values, it is possible for two samples of different materials, of the same age, to have different levels of radioactivity and different 14 C ...
