Tyrosol

Isicelo
ITyrosol sisimbindi sepetalol kwaye isetyenziswa ikakhulu ukwenza i-cardiovascular drug metoprolol.Isetyenziselwa ukutshisa i-zero valent iron ukwenzela i-catalytic oxidation ye-organic acids kumanzi amdaka e-olive mill.

p-Hydroxyphenethylalcohol, p-Hydroxy-benzeneethanol, ekwaziwa njenge 4-Hydroxyphenethyl alcohol, beta-(4-hydroxyphenyl) ethanol, 2-(4-hydroxyphenyl) ethanol, kunye neTyrosol.Hydroxyphenyl) ethanol, 2-(4-hydroxyphenyl) ethanol, eyaziwa njengeTyrosol.Yikristale emhlophe kubushushu begumbi, inyibilika etywaleni nakwi-ether, inyibilika kancinane emanzini.Inokutsha kwaye inomngcipheko wokutshisa xa ibonakaliswe kwiqondo lokushisa eliphezulu, ilangatye elivulekileyo okanye i-oxidizing agent.Inokucaphukisa amehlo, ulusu kunye nenkqubo yokuphefumla, ukungabikho kwedatha kwityhefu, ubuthi bayo bunokubhekiswa kwi-phenol.Ikakhulu isetyenziswa kwi-synthesis ye-cardiovascular drug Medocin.Ifomula yemolekyuli yi-C8H10O2.

Ubuthi kunye nefuthe lokusingqongileyo: inokucaphukisa amehlo, ulusu kunye nenkqubo yokuphefumula, ukungabikho kwedatha yetyhefu, ubuthi bayo bunokubhekiswa kwi-phenol.Kufuneka uzixhalabise ngeziphumo ezibi zenkunkuma yenkqubo yemveliso kunye neemveliso eziphuma kwindalo esingqongileyo.

Ukupakisha, ukuthuthwa kunye nokugcinwa: i-p-hydroxyphenylethanol ifakwe kwiidramu zekhadibhodi ezihlanganiswe kunye neengqimba ezimbini zefilimu ye-polyethylene okanye i-kraft paper, i-25KG / idrum.Gcina kude ne-oxidizing agent, umlilo kunye nomthombo wobushushu, gcina kwindawo evaliweyo kwaye uyibeke kwindawo engena umoya, epholileyo kunye neyomileyo.

Izindlela zokuvelisa: (1) I-Hydroxyacetophenone njengento eluhlaza, i-oxidized nge-aliphatic nitrile, emva koko i-hydrolyzed ukufumana i-p-hydroxyphenyl glyoxal, enokufumaneka ngokunciphisa i-p-hydroxyphenylethanol.
(2) efunyenwe nge-oxidation kunye ne-β-aminophenethyl yotywala njengento eluhlaza.
