2,6-Dichlorophenol is a compound with formula C 6 H 3 Cl 2 OH. It is one of the six isomers of dichlorophenol. It is a colorless solid. Its pK a is 6.78, which is about 100x more acidic than 2-chlorophenol (8.52) and 1000x more acidic than phenol itself (9.95). [3]
Mixture of 41% of furfuryl alcohol, 41% of xylidine and 18% of methanol, called Furaline, was used in France for experimental rocket engines for aircraft, developed by SEPR. [ 13 ] In late 2012, Spectra, a concept liquid rocket engine using white fuming nitric acid as the oxidizer to furfuryl alcohol fuel was static tested by Copenhagen ...
2,6-DMP is produced by the methylation of phenol. With production >100,000 tons/y, it is the most important xylenol. The methylation is carried out by contacting gaseous phenol and methanol at elevated temperatures in the presence of a solid acid catalyst: [2] [3] C 6 H 5 OH + 2 CH 3 OH → (CH 3) 2 C 6 H 3 OH + 2 H 2 O
The 2,6 and 3,5 isomers do not form acceptably from toluene or chlorotoluenes, so these isomers are prepared by indirect methods. For example, 2,6-dichlorotoluene can be prepared by chlorination of 4-toluenesulfonyl chloride followed by desulfonation .

2,6-di-tert-butylphenol is a precursor to more complex compounds used as antioxidants and light-protection agents for the stabilization for polymers. Of particular note is methyl-3-(3,5-di- tert -butyl-4-hydroxyphenyl)-propionate (CAS# 6386-38-5), which is formed by the Michael addition of methyl acrylate .
Poly(2,6-diphenylphenylene oxide) is a low bleeding material with a low level of impurities, and has a high thermal stability (up to 350 °C). Before use poly(2,6-diphenylphenylene oxide) should be thermally conditioned with a high purity gas at elevated temperatures to remove any residual components.
2,6-Dichloroquinone-4-chloroimide (Gibbs reagent) is an organic compound used as an colorimetric indicator to detect phenolic compounds. [1] Upon reaction with phenol itself, 2,6-dichlorophenolindophenol is formed, [ 2 ] a chemical that is used as a redox indicator .
