Ko te 4-Hydroxybenzophenone, e mohiotia ana ko te p-benzoylphenol me te p-hydroxybenzophenone, he matū paura tioata ma me te tauira mole C13H10O2 me te taumaha ngota 198, ka taea te whiwhi ma te whakamahana me te whakatikatika i te waikawa benzoic phenyl ester.Kei te whakamahia i roto i te whakahiato waro, he takawaenga o te exoclomiphene tarukino anti-kore.He whakapataritari ki nga kanohi, te punaha manawa me te kiri, karohia te pa ki te kiri me nga kanohi.
Nature me te pumau:
Karekau he pirau ki te whakamahia me te rongoa i runga i nga whakaritenga, kaore he tauhohenga morearea e mohiotia ana, karohia te waikura
Tikanga Rokiroki:
Kia hiri nga ipu, rongoa ki te waahi makariri, maroke, kia pai te hau, te ruha ranei i roto i te rūma mahi.
Tikanga Whakakotahi:
Whakawerahia te phenyl ester waikawa benzoic ki te 70 ℃ rewa, te whakaoho tere ki te konumohe trichloride anhydrous, te tauhohenga mawhiti hauwai pūhaumāota, me te whakamahana whaiaro, te tauhohenga i te 130 ℃ mo te 15 min.mātao, tāpiri waikawa pūmāota waimeha.Tātarihia ka horoi ki te wai kia kūpapa.I rerystallized te keke tātari ki te benzene ki te hoatu 4-hydroxydiphenyl ketone i roto i te 62% hua.
Whakaahuatanga o nga whakamahinga:
Ka whakamahia i roto i te whakahiato waro, nga takawaenga rongoa me te anti-UV.
Raraunga Kaiao:
