white crystalline powder or chips. 4-Hydroxybenzonitrile [767-00-0], 4-cyanophenol, 1-cyano-4-hydroxybenzene, Mr 119.2, forms colorless crystals of mp 113℃. 4-Hydroxybenzonitrile is produced by reaction of 4-bromophenol with copper (I) cyanide, by ammoxidation of p-cresol, by reaction of 4-chlorobenzonitrile with sodium methoxide, or by the catalyzed gas phase reaction of ethyl 4-hydroxybenzoate with ammonia. The nitrile is used for the production of the herbicides 3,5-dibromo- and 3,5-diiodo-4- hydroxybenzonitrile (Bromoxynil, Ioxynil, May & Baker).??
4-Cyanophenol is a precursor for the synthesis of a vasodilator, Levcromakalim. Bromination of 4-cyanophenol results in bromoxynil, a commercial herbicide. It can also be used as a component of deep eutectic solvent (DES) mixture.?? ??
4-Cyanophenol is produced by reaction of 4-bromophenol with copper (I) cyanide, by ammoxidation of p-cresol, by reaction of 4-chlorobenzonitrile with sodium methoxide, or by the catalyzed gas phase reaction of ethyl 4-hydroxybenzoate with ammonia.Purification Methods
Crystallise the phenol from pet ether, *benzene or water and keep it under vacuum over P2O5. [Bernasconi & Paschelis J Am Chem Soc 108 2969 1986.] [Beilstein 10 H 167, 10 IV 441.]4-?????? ?? ?? ? ???
