I-Menthol [1490-04-6]
I-Menthol wutshwala obutholakala emafutheni ahlukahlukene e-mint noma owenziwe ngokwenziwa.I-Menthol ingaba i-levorotatory (L-Menthol), evela emithonjeni yemvelo noma yokwenziwa, noma i-racemic (DL-Menthol).
Ukupakisha nokugcina-Londoloza ezitsheni eziqinile, okungcono ekamelweni lokushisa elilawulwayo.
Ukulebula-Kufake ilebula ukuze ubonise ukuthi i-levorotatory noma i-racemic.
Ukuhlonza-Uma ihlanganiswa ngesisindo esilinganayo se-camphor, se-chloral hydrate, noma se-phenol, ingxube iyancibilika.
Ukuncibilika kwebanga le-L-Menthol <741>: phakathi kuka-41° no-44°
Uhla oluqinile lwe-DL-Menthol <651>-[QAPHELA-Yenza lokhu kuhlola okungcono kakhulu ekamelweni elinezinga lokushisa elingaphansi kuka-30° kanye nomswakama ohlobene ongaphansi kuka-50%.] Beka cishe u-10 g we-Racemic Menthol, omiswe ngaphambilini ku-desiccator phezu kwe-silica ijeli amahora angu-24, kushubhu yokuhlola eyomile ukusuka ku-18- kuya ku-20-mm ububanzi bangaphakathi, bese uncibilikisa okuqukethwe ekushiseni okungaba ngu-40 °.Misa ishubhu lokuhlola emanzini anezinga lokushisa elingu-23° ukuya ku-25°, bese ushukumisa okuqukethwe kweshubhu ngokuqhubekayo nge-thermometer, ugcine isibani se-thermometer sicwiliswa oketshezini.I-Racemic Menthol igoqeka emazingeni okushisa aphakathi kuka-27° no-28°.Ngokushesha ngemva kokuba izinga lokushisa lizinzile endaweni yokugxumela, engeza ama-mg ambalwa e-racemic Menthol eningi elijiyile, bese uqhubeka nokunyakazisa: ngemva kwemizuzu embalwa izinga lokushisa lesisindo likhuphuka ngokushesha libe ngu-30.5 ° kuya ku-32.0 °.
Ukuzungezisa okuqondile <781S>: phakathi kuka -45° no -51° ku-L-Menthol;phakathi kuka -2° kanye +2° ku-DL-Menthol.Isixazululo sokuhlola: 100 mg ngemL ngayinye, kutshwala.
Umkhawulo wezinsalela ezingaguquguquki-Vulanisa u-2 g, ukalwe ngokunembile, endishini ye-porcelain evulekile enethayela ebhavini lesitimu, bese womisa insalela ku-105° ihora elingu-1: isisindo esisele singeqi ku-1 mg (0.05%).
Ubumsulwa beChromatographic-
Ukulungiswa kokufaneleka kwesistimu-Dissolve decanol kanye ne-Mentho ku-ether ukuze uthole isixazululo esinokugxila okungaba ngu-0.05 mg ku-mL ngayinye.
Ukulungiselela ukuhlolwa-Chaza u-10 mg weMenthol ku-50 mL we-ether, bese uxuba.Nciphisa u-25 ml walesi sixazululo nge-ether uye ku-100mL, bese uxuba.
Isistimu ye-Chromatographic-I-chromatograph yegesi ifakwe umtshina we-ionization yomlilo futhi iqukethe ikholomu engu-1.8-m× 2-mm epakishwe nesigaba esingu-10% se-G16 ekusekelweni kwe-S1AB.Ikholomu igcinwa cishe ku-170 °, imbobo yomjovo igcinwa cishe ku-260 °, futhi ibhulokhi yomtshina igcinwa cishe ku-240 °.I-helium eyomile isetshenziswa njengegesi ethwala ngesilinganiso sokugeleza esingaba ngu-50 mL ngomzuzu.I-Chromatograph yokulungiswa kokufaneleka Kwesistimu, futhi urekhode izimpendulo eziphezulu njengoba kuqondiswe ngaphansi Kwenqubo: isikhathi sokugcinwa kwe-menthol sicishe sibe ngu-0.7 ngokuhlobene ne-decanol.Ku-chromatogram efanelekile, ukulungiswa R, kweziqongo ezingu-2 akukho ngaphansi kuka-2.5, futhi ukuchezuka okujwayelekile okuhlobene kwesilinganiso sempendulo ephakeme kakhulu etholwe nge-Menthol naleyo etholwe nge-decanol ayikho ngaphezu kuka-2%.
Inqubo-Jova cishe u-2 µL wokulungiselelwa Kokuhlola ku-chromatograph yegesi, bese ukala izimpendulo eziphezulu.Impendulo ephezulu ngenxa ye-menthol ayikho ngaphansi kwama-97% yenani lazo zonke izimpendulo eziphakeme, ngaphandle kwanoma yiziphi ngenxa ye-ether.
Izinto ezitholakala kalula ku-DL-Menthol-Place 500mg ye-DL-Menthol eshubhuni lokuhlola elihlanzekile, elomile, engeza u-10 mL wesisombululo se-potassium permanganate, esilungiswe ngokuhlanjululwa u-3 mL we-0.1 N potassium permanganate ngamanzi ku-100 mL, bese ubeka ithubhu lokuhlola kubhekha wamanzi ezingeni lokushisa eliphakathi kuka-45° no-50°.Susa ithubhu ekugezeni ngezikhathi zemizuzwana engu-30, bese uxuba ngokushesha ngokuthuthumela: umbala onsomi we-potanganum permanganate usabonakala ngemva kwemizuzu engu-5.
