I-P-tert-butyl phenol crystal emhlophe, evutha umlilo, enephunga elincane le-phenol.Iphoyinti elincibilikayo 98-101℃, indawo yokubilisa 236-238℃, 114℃ (1.33kPa), ukuminyana kwesihlobo 0.908 (80/4℃), inkomba ye-refractive 1.4787.Incibilika ku-acetone, benzene, methanol, inyibilika kancane emanzini.Ingahwamuka ngomhwamuko wamanzi.Lungiselela...Funda kabanzi -
Izici zamakhemikhali ze-p-tert-butylphenol
I-flake elimhlophe noma elimhlophe eliqinile, elivutha umlilo kodwa elingashi, elinephunga elihlukile le-alkyl phenol.Incibilika otshwaleni, i-ester, i-alkane, iphunga elimnandi nezinye izincibilikisi eziphilayo, njenge-ethanol, i-acetone, i-butyl acetate, uphethiloli, i-toluene, inyibilika kusixazululo esiqinile se-alkali.Ngezici ezijwayelekile ze...Funda kabanzi -
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, kanye...Funda kabanzi -
Idatha ye-Toxicological nokuziphatha kwemvelo kwe-4-tert-butylphenol
Ubuthi obunamandla: LD503250mg/kg(igundane elidlulayo);2520mg/kg(Rabbit Transdermal) Iyacasula: Iso le-rabbit meridian: 250ug(amahora angama-24), ukuvuselela okukhulu.I-Rabbit transdermal: 500mg(24 h), ukucasuka okuncane.Izici eziyingozi: ezivuthayo uma kwenzeka ilangabi elivulekile noma ukushisa okuphezulu.Ingasabela ngokuqinile nge-oxidan...Funda kabanzi -
Ubuthi kanye nemiphumela yemvelo ye-p-tert-butyl phenol
Ubuthi kanye nomthelela emvelweni Lo mkhiqizo ungowobuthi bamakhemikhali.Ukuhogela umoya, ukuthintana nekhala, amehlo noma ukumunca kungacasula amehlo, isikhumba nolwelwesi lwamafinyila.Ukuthintana kwesikhumba kungabangela i-dermatitis kanye nobungozi bokusha.Umkhiqizo ungasha emlilweni ovulekile;Ukubola kokushisa kukhipha igesi enobuthi;T...Funda kabanzi -
Ukusetshenziswa kwe-p-tert-butyl phenol
I-P-tert-butyl phenol iyingxenye ebalulekile ye-organic synthesis.Ukusetshenziswa okuyinhloko yilezi: isetshenziswa njengesithuthukisi sokukhiqizwa kwe-alkyd resin;Isetshenziswa njengowoyela wokusika, isengezo samafutha okugcoba;Isetshenziswa njenge-polypropylene nucleating agent;Isetshenziswa njengesivikelo sokudla;Isilawuli se-polyester polymerizatio...Funda kabanzi -
