synthetic vitamin E by methylation to give 2,3,6-trimethylphenol [3] antiseptics, such as amylmetacresol; a solvent for polymers. For example, polyaniline is cast from a solution of m-cresol to form a polyaniline film with a superior conductivity than polyaniline alone. This phenomenon is known as secondary doping. [4] preservatives in some ...

ch 3 c 6 h 4 so 3 h + 2 naoh → ch 3 c 6 h 4 oh + na 2 so 3 + h 2 o Other methods for the production of p -cresol include chlorination of toluene followed by hydrolysis. In the cymene-cresol process, toluene is alkylated with propene to give p -cymene , which can be oxidatively dealkylated in a manner similar to the cumene process .
4-Isopropylphenol is an organic compound with the formula (CH 3) 2 CHC 6 H 4 OH.The molecule consists of an isopropyl group affixed to the para (p-) position of phenol.The compound, a white solid, is produced by the alkylation of phenol with propylene and is relevant to the production of the commodity chemical bisphenol A (BPA).
