English

Subject field(s)
  • Chemical Elements and Compounds
DEF

An aromatic alcohol having the composition (C6H4OH)2 (that of phenol being C6H5OH) [which] has isomeric modifications crystallizing in colourless rhombic crystals and in shining needles.

CONT

The dose of ozone varies according to whether the water contains pure phenol which is rare or diphenols, triphenols, cresols or naphthols, and according to whether these substances are associated with other compounds such as thiocyanates, sulphides, etc.

OBS

diphenol: This name must be replaced by the expression "aromatic diol." It is also erroneously used to designate the following compounds: 1,1'-biphenyldiol, 2,2'-biphenyldiol, and 4,4'-biphenyldiol (q.v.).

DEF

Composé possédant deux fois la fonction phénol, comme l'hydroquinone, l'alizarine, l'adrénaline, etc.

CONT

Les doses d'ozone à mettre en œuvre varient suivant qu'on est en présence de phénol pur, ce qui est rare, de di ou triphénols, de crésols ou de napthols et suivant que ces corps sont conjugués à d'autres composés tels que des thiocyanates, des sulfures, etc.

OBS

diphénol : Ce nom doit être remplacé par l'expression «diol aromatique». Il est aussi utilisé, à tort, pour désigner le 1,1'-biphényldiol, le 2,2'-biphényldiol et le 4,4'-biphényldiol (voir aussi ces fiches).
