Ukulungiswa nokuphepha kwe-p-tert-butylphenol

Indlela yokulungiselela: i-phenol ne-isobutene ziphekwe phambi kwe-zinc chloride noma i-tert-butanol yasetshenziswa njenge-catalyst ne-sulfuric acid ku-100 ℃.Umkhiqizo ongahluziwe uhlanganiswa kabusha nge-ethanol ukuze uthole umkhiqizo owufunayo.

Ukuphepha: I-acute transoral LD50 yamagundane ingu-0.56-3.5g/kg, kanti i-LD50 ye-percutaneous yonogwaja ingu-7.5g/kg.Ngaphansi kwesimo esivaliwe, umkhiqizo wasetshenziswa esikhumbeni sikanogwaja usuku olungu-1 futhi watholakala unomphumela ocasulayo.Ukuhlolwa kokuthinta isikhumba kuka-1% uVaseline kwenziwa emzimbeni womuntu.Akukho ukucasuka okutholakele ngemuva kwezinsuku ezimbili zokufaka isicelo.
