Isicelo
I-Tyrosol iyi-intermediate ye-petalol futhi isetshenziselwa ikakhulukazi ukuhlanganisa umuthi wenhliziyo nemithambo ye-metoprolol.Isetshenziselwa ukugaya i-zero valent iron for catalytic oxidation of organic acids emanzini angcolile okugaya i-olive.
i-p-Hydroxyphenethylalcohol, p-Hydroxy-benzeneethanol, eyaziwa nangokuthi i-4-Hydroxyphenethyl alcohol, beta-(4-hydroxyphenyl) ethanol, 2-(4-hydroxyphenyl) ethanol, neTyrosol.I-Hydroxyphenyl) ethanol, i-2-(4-hydroxyphenyl) ethanol, evame ukubizwa ngeTyrosol.Kuyikristalu emhlophe ekamelweni lokushisa, kuncibilika otshwaleni ne-ether, kuncibilika kancane emanzini.Iyakwazi ukuvutha futhi inobungozi bokuvutha lapho ibhekene nezinga lokushisa eliphezulu, ilangabi elivulekile noma i-oxidizing agent.Ingacasula amehlo, isikhumba nesistimu yokuphefumula, ukuntuleka kwedatha ngobuthi, ubuthi bayo bungabhekiselwa ku-phenol.Ikakhulukazi esetshenziswa ekuhlanganiseni izidakamizwa senhliziyo nemithambo yegazi Medocin.Ifomula yemolekyuli ithi C8H10O2.
Ubuthi kanye nomthelela wemvelo: kungacasula amehlo, isikhumba kanye nesistimu yokuphefumula, ukuntuleka kwedatha yobuthi, ubuthi bayo bungabhekiselwa ku-phenol.Kufanele sikhathazeke ngemiphumela emibi yenqubo yokukhiqiza udoti kanye nemikhiqizo etholakalayo endaweni ezungezile.
Ukupakisha, ukuthutha kanye nokugcinwa: i-p-hydroxyphenylethanol ifakwe ezigubhu zekhadibhodi ezifakwe izingqimba ezimbili zefilimu ye-polyethylene noma iphepha le-kraft, 25KG/ isigubhu.Gwema i-oxidizing ejenti, umthombo womlilo nokushisa, gcina endaweni evalekile bese uyibeka endaweni engenawo umoya, epholile futhi eyomile.
Izindlela zokukhiqiza: (1) I-Hydroxyacetophenone njengento eluhlaza, i-oxidized nge-aliphatic nitrile, bese i-hydrolyzed ukuthola i-p-hydroxyphenyl glyoxal, engatholakala ngokunciphisa i-p-hydroxyphenylethanol.
(2) etholwe nge-oxidation nge-β-aminophenethyl alcohol njengento eluhlaza.
