P-tert-Butylphenol

A few synthetic substituted phenols are also used in the manufacture of oil-soluble resins. They include p-tert-butylphenol, / -tert-amylphenol, p-tert-octylphenol, /7-phenylphenol and dihydroxyphenylpropane (bis-phenol A).

A slurry prepared from 100 g (0.67 mol) of p-tert-butylphenol, 35 g (ca. 1.1 mol) of paraformaldehyde (Note 1), and 2.0 mL (0.02 mol) of 10 N sodium hydroxide (Note 2) 1n 600 mL of xylene Is placed in a 2-L, round-bottomed, three-necked flask fitted with a Dean-Stark water collector and a mechanical stirrer. The air in the flask is replaced with nitrogen, and the stirred contents of the flask are heated to reflux by means of a heating mantle. After 30 min a homogeneous solution is obtained, and after 1 hr a white precipitate begins to form. The reaction mixture is refluxed for 4 hr, the heating mantle is removed, the mixture is allowed to cool to room temperature, and the precipitate is removed by filtration. The crude product Is washed, in succession, with 400-mL portions of toluene, ether, acetone, and water and is... 

These include oxidation of l-phenyl-3-heptanol acetate (12 g) to 4-(acetyloxy) octanoic acid (RuClj/aq. IO(OH)j/CCl4-CH3CN) [251] phenylcyclohexane (4 g) to cyclohexanecarboxylic acid (RuClj/aq. Na(10yCCy p-tert-butylphenol (3 g) to pivalic acid, phenylcyclohexane (4g) to cyclohexanecarboxylic acid (RuClj or RnO/aq. Na(IO,)/CCy60 C) [241].

The bactericidal and fungicidal activity of p-trimethylsilylphenol 14b) was already reported in 1953 83. This compound (syntheses83-85 are described in Scheme 13) is a silicon analogue of the antiseptic p-tert-butylphenol (II4a) ... 

The calix[ ]arene ( indicates the number of aromatic units in the metacyclophane) building block provides a three-dimensional skeleton that is needed to fix different donor ligands in the optimal spatial positions for binding one ion selectively [94,95]. Calix[n]arenes are easily accessible from the base-eatalyzed condensation of p-tert-butylphenol and formaldehyde [96]. Gutsche proposed to define the two faces of a calix[4]arene molecule as the lower (phenolic groups) and the upper rim. The calix[4]arene with free hydroxyl groups is conformationally flexible and the...

Figure 1.31 gives one example of a comparison between results from two different techniques, applied to one and the same system. In this case the (rton-ionic) surfactant was specially synthesized and well-defined p-tert.butylphenol with 10 EO groups. It is seen that the results of the (faster) maximum bubble technique and the (slower) drop volume method, connect well. Many more...
