IiPropati zoMzimba kunye nezeMichiza (s) -3-hydroxy-gamma butyrolactone lulwelo olungenambala, lunyibilika emanzini, utywala kunye nezinye izinyibilikisi eziphilayo, ezinganyibilikiyo kwi-petroleum ether, njl., ibaluleke kakhulu i-organic synthesis intermediates, ikwangumthombo obaluleke kakhulu ububele. Isetyenziswa kakhulu njengengundoqo ephakathi kwe-Modulator (R) -gamma-hydroxy-beta-Q i-hydroxybutyric acid [(R) -GABOB], (R) -GABOB isetyenziselwa ukunyanga i-hyperlipidemia; (s) -I-Oxiracetam ngumgqugquzeli wengqondo imetabolism, kodwa kunye ne-synthesis yayo; Ukunciphisa kwayo kunokufumaneka (s) -3-hydroxytetrahydrofuran, eyona nto ibalulekileyo ephakathi kunyango lwe-AIDS; i-(s) -3-hydroxy-4-bromobutyric acid edityaniswe kuyo yi-stabilizer enokubakho; Iguqulwa ibe yi-(s) -5-hydroxymethyl-1, i-3-oxazolin-2-enye ekhoyo kwisizukulwana samva samachiza e-antibacterial; Ukongeza, (s)-n-methyl-3-hydroxypyrrole kunye (R)-N-methyl -3-methyl-pyrrole nazo zinomsebenzi obalulekileyo we-physiological, zinokufunyanwa ngokuguqulwa okulula kwe (s) -3-hydroxy- gamma butyrolactone. Iimveliso ezininzi zendalo zinokuphinda zenziwe ukusuka kwi-(s) -3-hydroxy-γbutyrolactone.

Intshayelelo

(S) -3-hydroxy-γ-butyrolactone i-organic compound. Lulwelo olungenambala nencasa eswiti, eneziqhamo.

 

Kukho iindlela ezininzi zokulungiselela (S) -3-hydroxy-γ-butyrolactone, efumaneka ngokuqhelekileyo nge-catalytic hydrogenation. Indlela ethile yokusabela umlinganiselo ofanelekileyo we-γ-butyrolactone kunye ne-catalyst (efana ne-alloy-lead alloy) kwiqondo lokushisa elifanelekileyo kunye noxinzelelo, kwaye emva kwe-catalytic hydrogenation, (S) -3-hydroxy-γ-butyrolactone ifunyenwe.

 

Ulwazi loKhuseleko: (S) -3-hydroxy-γ-butyrolactone inetyhefu ephantsi phantsi kweemeko zokusetyenziswa ngokubanzi kwaye ayiyiyo ikhemikhali eyingozi. Ukunyamekela kufuneka kuthathwe ukuphepha ukudibanisa nolusu, amehlo, kunye nokuphefumula ngexesha lokusetyenziswa. Kwimeko yokudibana ngengozi, hlambulula ngamanzi kwaye ufune unyango ngexesha. Ikhompawundi kufuneka igcinwe kude nokutshisa kunye neendawo zokushisa eziphezulu, kwaye ugweme ukudibanisa nee-oxidants kunye ne-acids. Ukongezelela, kufuneka isetyenziswe ngokuhambelana neenkqubo ezifanelekileyo zokusebenza kunye nemilinganiselo yokusebenza ekhuselekileyo.
