2-Ethylphenol is an organic compound with the formula C 2 H 5 C 6 H 4 OH. It is one of three isomeric ethylphenols. A colorless liquid, it occurs as an impurity in xylenols and as such is used in the production of commercial phenolic resins. It is produced by ethylation of phenol using ethylene or ethanol in the presence of aluminium phenolate. [2]
In water, measurable pK a values range from about −2 for a strong acid to about 12 for a very weak acid (or strong base). A buffer solution of a desired pH can be prepared as a mixture of a weak acid and its conjugate base. In practice, the mixture can be created by dissolving the acid in water, and adding the requisite amount of strong acid ...
Phenol is readily alkylated at the ortho positions using alkenes in the presence of a Lewis acid such as aluminium phenoxide: [citation needed] CH 2 =CR 2 + C 6 H 5 OH → R 2 CHCH 2 -2-C 6 H 4 OH More than 100,000 tons of tert-butyl phenols are produced annually (year: 2000) in this way, using isobutylene (CH 2 =CMe 2 ) as the alkylating agent.
Ortho effect is an organic chemistry phenomenon where the presence of a chemical group at the at ortho position or the 1 and 2 position of a phenyl ring, relative to the carboxylic compound changes the chemical properties of the compound.
The general structure of a phenol ether. In chemistry, a phenol ether (or aromatic ether) is an organic compound derived from phenol (C 6 H 5 OH), where the hydroxyl (-OH) group is substituted with an alkoxy (-OR) group.
For instance, hydrogen fluoride, whether dissolved in water (= 3.2) or DMSO (= 15), has values indicating that it undergoes incomplete dissociation in these solvents, making it a weak acid. However, as the rigorously dried, neat acidic medium, hydrogen fluoride has an H 0 {\displaystyle H_{0}} value of –15, [ 1 ] making it a more strongly ...
1/2 c. (40 g.) unsweetened cocoa powder. Directions. Preheat oven to 350°. Grease a 13"-x-9" metal baking pan with cooking spray. Line pan with foil, leaving an overhang on 2 opposite sides ...
Phenolic acids can be found in many plant species. Their content in dried fruits can be high.. Natural phenols in horse grams (Macrotyloma uniflorum) are mostly phenolic acids, namely 3,4-dihydroxy benzoic, p-hydroxy benzoic, vanillic, caffeic, p-coumaric, ferulic, syringic, and sinapinic acids.
