Benzenesulfonic acid CAS 98-11-3
Benzenesulfonic acid ke kristale e se nang 'mala ea sebopeho sa nale kapa e bōpehileng joaloka lekhasi, e qhibilihang haholo metsing le ethanol, ha e qhibilihe ka har'a ether le carbon disulfide, 'me e qhibiliha hanyenyane ho benzene. E na le asiti e matla, e ka bapisoa le sulfuric acid, empa ha e na oxidizing. The dissociation Chemicalbook constant K=0.2 (25 ℃). Sehlopha sa sulfonic acid sa benzenesulfonic acid se ka nkeloa sebaka ke lihlopha tse fapaneng tse sebetsang 'me sa kopanngoa le sodium hydroxide ho etsa sodium phenolate; Sebetsa ka sodium cyanide ho hlahisa benzonitrile; Etsa ka bromine ho hlahisa bromobenzene;

Benzenesulfonic acid e atisa ho sebelisoa e le ntho e thusang le ho monya metsi ho esterification le ho felloa ke metsi 'meleng. Molemo oa eona ke hore e na le thepa e fokolang ea oxidizing ho feta sulfuric acid 'me e ka fokotsa maikutlo a mahlakoreng. Benzenesulfonic acid e sebelisoa haholo-holo bakeng sa ho qhibiliha ha alkali ho hlahisa phenol, hammoho le bakeng sa tlhahiso ea resorcinol, 'me hangata e sebelisoa e le mohloli oa esterification le dehydration reactions. Benzenesulfonic acid e ka boela ea sebelisoa bakeng sa ente ea metsi sebakeng sa oli, e ka imollang ho thibela sebopeho le ho ntlafatsa ho phunyeha ha sebopeho. Asiti ea Benzenesulfonic e boetse e sebelisoa e le sesosa sa karabelo ea esterification le dehydration, hape e le sesebelisoa se phekolang indastering ea ho lahla.
