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 ...
It is a popular solvent for commercial applications. [1] It is produced by the ethoxylation of ethanol (CH 3 CH 2 OH). Applications ... Toggle the table of contents ...
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.
It is formed by the ethoxylation chemical reaction of dodecanol (lauryl alcohol) to give a material with 5 repeat units of ethylene glycol. Multilamellar vesicle formation [ edit ]
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).
Figure 1: Calculate impurity profile after an infinite number of recycles as a function of the fraction of mother liquors reused Chemical law term - deprecated The mother liquor (or spent liquor) is the solution remaining after a component has been removed by a process such as filtration or more commonly crystallization .
Animal fat is hydrolysed to give a mixture of free fatty acids, typically oleic (37–43%), palmitic (24–32%), stearic (20–25%), myristic (3–6%), and linoleic (2–3%). ). These are then converted to fatty amines via the nitrile process before being ethoxylated with ethylene oxide; this makes them water-soluble and amphiphi
Similar monomers used are 1,6-hexanediol diacrylate and trimethylol propane triacrylate. It is a derivative of pentaerythritol [2] One of the key uses of the material is in polymeric synthesis where it can form micelles and block copolymers. [3] [4] The molecule's acrylate group functionality enables the molecule to do the Michael reaction with ...
