Tom ntej: Benzenesulfonic Acid CAS 98-11-3
Benzenesulfonic acid yog cov xim tsis muaj xim zoo li lub ntsej muag lossis nplooj zoo li lub ntsej muag uas yog soluble hauv dej thiab ethanol, insoluble hauv ether thiab carbon disulfide, thiab me ntsis soluble hauv benzene. Nws muaj zog acidic, piv rau sulfuric acid, tab sis tsis oxidizing. Lub dissociation Chemicalbook tas li K = 0.2 (25 ℃). Cov pab pawg sulfonic acid ntawm benzenesulfonic acid tuaj yeem hloov tau los ntawm ntau pawg ua haujlwm thiab fused nrog sodium hydroxide los ua sodium phenolate; React nrog sodium cyanide los tsim benzonitrile; React nrog bromine los tsim bromobenzene;

Benzenesulfonic acid feem ntau yog siv los ua catalyst thiab dej absorbent hauv esterification thiab lub cev qhuav dej. Nws qhov zoo dua yog tias nws muaj zog oxidizing tsis muaj zog dua li sulfuric acid thiab tuaj yeem txo cov kev mob tshwm sim. Benzenesulfonic acid feem ntau yog siv rau alkali yaj los tsim phenol, nrog rau kev tsim cov resorcinol, thiab feem ntau yog siv los ua cov catalyst hauv esterification thiab lub cev qhuav dej. Benzenesulfonic acid kuj tseem siv tau rau kev txhaj tshuaj hauv dej, uas tuaj yeem txo qhov tsim thaiv thiab txhim kho kev tsim permeability. Benzenesulfonic acid kuj tseem siv los ua ib qho catalyst rau esterification thiab lub cev qhuav dej, thiab ua tus neeg sawv cev kho hauv kev lag luam casting.
