Menthol [1490-04-6]
I-Menthol butywala obufunyenwe kwii-oyile ezahlukeneyo ze-mint okanye ezilungiselelwe ngokwenziwa.I-Menthol ingaba yi-levorotatory (L-Menthol), ukusuka kwimithombo yendalo okanye yokwenziwa, okanye i-racemic (DL-Menthol).
Ukupakishwa kunye nokugcinwa-Londoloza kwizikhongozeli eziqinileyo, ngokukodwa kwiqondo lokushisa elilawulwayo.
Ileyibheli-Ileyibhelishe ukubonisa ukuba i-levorotatory okanye i-racemic.
Ukuchonga-Xa i-triturated malunga nobunzima obulinganayo be-camphor, ye-chloral hydrate, okanye ye-phenol, umxube uyanyibilika.
Uluhlu olunyibilikayo lwe-L-Menthol <741>: phakathi kwe-41 ° kunye ne-44 °
Uluhlu olujiyileyo lwe-DL-Menthol <651>-[QAPHELA-Qinisekisa olu vavanyo kukhethwa kwigumbi elineqondo lobushushu elingaphantsi kwe-30 ° kunye nokufuma okungaphantsi kwama-50%.] Beka malunga ne-10 g ye-racemic Menthol, yomiswe ngaphambili kwi-desiccator phezu kwe-silica ijeli kwiiyure ezingama-24, kwityhubhu yokuvavanya eyomileyo ukusuka kwi-18 ukuya kwi-20-mm ububanzi bangaphakathi, kwaye unyibilike iziqulatho kwiqondo lokushisa malunga ne-40 °.Gxisa ityhubhu yovavanyo emanzini aneqondo lobushushu elingama-23° ukuya kuma-25°, kwaye ushukumise imixholo yombhobho ngokuqhubekayo ngethemometha, ugcine ibhalbhu yethemometha intywiliselwe kulwelo.I-Menthol yeRacemic ijiya kwiqondo lobushushu phakathi kwe-27 ° kunye ne-28 °.Kungekudala emva kokuba iqondo lokushisa lizinzile kwindawo yokudibanisa, yongeza i-mg ye-racemic eyomileyo i-Menthol kwi-mass mass, kwaye uqhubeke nokuvuselela: emva kwemizuzu embalwa ubushushu bobunzima buphakama ngokukhawuleza kwi-30.5 ° ukuya kwi-32.0 °.
Ukujikeleza okuthe ngqo <781S>: phakathi -45 ° kunye -51 ° ye-L-Menthol;phakathi -2 ° kunye +2 ° ye-DL-Menthol.Isisombululo sovavanyo: 100 mg nge-mL nganye, etywaleni.
Umda we-nonvolatile residue-Volatilize 2 g, ulinganiswe ngokuchanekileyo, kwisitya se-porcelain esivulekileyo se-tared kwindawo yokuhlamba umphunga, kwaye uyomise intsalela kwi-105 ° ngeyure ye-1: intsalela inobunzima obungaphezu kwe-1 mg (0.05%).
Ukucoceka kweChromatographic-
Ukulungiswa kokufaneleka kwenkqubo-Dibanisa i-decanol kunye ne-Mentho kwi-ether ukufumana isisombululo esinogxininiso malunga ne-0.05 mg nganye nge-mL.
Ukulungiswa kovavanyo-Dibanisa i-10 mg ye-Menthol kwi-50 mL ye-ether, kwaye udibanise.Nciphisa i-25 mL yesi sisombululo nge-ether ukuya kwi-100mL, kwaye udibanise.
Inkqubo yeChromatographic-I-chromatograph yegesi ixhotyiswe nge-flame-ionization detector kwaye iqulethe ikholomu ye-1.8-m× 2-mm epakishwe nge-10% isigaba se-G16 kwinkxaso ye-S1AB.Ikholomu igcinwe malunga ne-170 °, i-injection port igcinwe malunga ne-260 °, kwaye ibhloko ye-detector igcinwe malunga ne-240 °.I-helium eyomileyo isetyenziswa njengerhasi yokuthwala ngesantya sokuhamba malunga ne-50 mL ngomzuzu.I-Chromatograph Ukulungiswa kokufaneleka kweSistim, kwaye urekhode iimpendulo eziphezulu njengoko zilawulwa phantsi kweNkqubo: ixesha lokugcinwa kwe-menthol malunga ne-0.7 malunga ne-decanol.Kwichromatogram efanelekileyo, isisombululo esingu-R, seencopho ezi-2 azikho ngaphantsi kwe-2.5, kwaye ukuphambuka komgangatho ohambelana nomlinganiselo wempendulo ephezulu efunyenwe nge-Menthol kuleyo ifunyenwe nge-decanol ayikho ngaphezu kwe-2%.
Inkqubo-Tofa malunga ne-2 µL yoLungiselelo loVavanyo kwikhromatograph yerhasi, kwaye ulinganise iimpendulo eziphezulu.Incopho yokuphendula ngenxa ye-menthol ayikho ngaphantsi kwe-97% yesamba sazo zonke iimpendulo eziphezulu, ngaphandle kweyiphi na ngenxa ye-ether.
I-oxidizable substances kwi-DL-Menthol-Place 500mg ye-DL-Menthol kwityhubhu yokuvavanya ecocekileyo, eyomileyo, yongeza i-10 mL yesisombululo se-potassium permanganate, elungiswe ngokuxutywa kwe-3 mL ye-0.1 N potassium permanganate ngamanzi kwi-100 mL, kwaye ubeke ityhubhu yokuvavanya kwi-beaker yamanzi kwiqondo lokushisa phakathi kwe-45 ° kunye ne-50 °.Susa ityhubhu kwindawo yokuhlambela ngexesha lemizuzwana engama-30, kwaye udibanise ngokukhawuleza ngokuxubha: umbala omfusa we-potassium permanganate usabonakala emva kwemizuzu emi-5.
