Methyl phenolate

Diasomethane Method. Diazomethane readily methylates phenolic hydroxy-compounds, primary and secondary amines, and carboxylic acids,... 

Actual water treatment challenges are multicomponent. For example, contamination of groundwater by creosote [8021-39-4], a wood (qv) preservative, is a recurring problem in the vicinity of wood-preserving faciUties. Creosote is a complex mixture of 85 wt % polycycHc aromatic hydrocarbons (PAHs) 10 wt % phenohc compounds, including methylated phenols and the remaining 5 wt % N—, S—, and O— heterocycHcs (38). Aqueous solutions of creosote are therefore, in many ways, typical of the multicomponent samples found in polluted aquifers.

However, heterocycles containing thiophenols have not been reported. It has been observed that the thiophe-nolate ion undergoes nucleophilic attack by the halo/ nitro compounds more easily than the phenolate ion in displacement reactions [37-39]. The experimental result shows that the reactivity of 3-nitro-N-phenyl-phthali-mide with 4-methyl-thiophenolate (reaction 1) is 100 times faster than that of 4-methyl phenolate [40] (reaction 2) ... 

A subsequent study, using clearly homogeneous conditions, of the dedeutera-tion of [2-2H]-4-nitro-, -chloro-, and -methyl-phenols by aqueous sulphuric acid showed that the rate coefficients clearly increased with increasing acidity (Table 120) and plots of log rate coefficient versus the acidity function — H0 were linear,...

Die Bamberger-Umlagerung zu Amino-phenolen ist oft Ziel der elektrochemischen Reduktion, so z. B. bei der kathodischen Reduktion von 6-Chlor-2-nitro-toluol zu 2-Chlor-4-amino-3-methyl-phenol (an Pt bis 78% d.Th.)2 und von 2-Chlor-l-nitro-benzol zu 3-Chlor-4-amino-phenol (bis 63% d.Th.)3 (die leicht zu 1,4-Benzochinonen oxidiert werden konnen). 

Clear soluble fluids. Cresol is a mixture of o-, m- and p-methyl phenol (Fig. 10.7A). Because of its poor solubility, it is solubilized with a soap prepared fiom linseed oil and potassium hydroxide. It forms a clear solution on dilution. This preparation, known as Lysol (Cresol and Soap Solution BP 1968) has been widely used as a general purpose disinfectant but has largely been superseded by less irritant phenolies. 

The pure enzyme was tested for activity against several methylated phenolic and cinnamic acids (Table 2). The enzyme was active on methyl esters of cinnamic acids caffeio p-coumaric> ferulic, and is therefore termed a cinnamoyl esterase (CinnAE).

Varma [106] determined iodide in seawater in amounts down to 2 mg/1 by a method based on pre-column derivatisation of the iodide into 4-iodo-2,6-di-methyl phenol. An ultraviolet detector was employed.
