I-Natural L-Menthol Crystal esetshenziswa njenge-Organic Phakami

Imininingwane Yomkhiqizo

Izakhiwo ze-L-MeTH, ukusetshenziswa kanye nenqubo yokukhiqiza
Izakhiwo zamakhemikhali ze-L-MeTH
Amakristalu afana nombala onjengemvuzo, ngephunga elipholile le-minty. I-REPORTE DENSITY D1515 = 0.890, I-Seling Point 41-43 ℃, I-Boiling Point 216 ℃, 111 ℃ (2.67kpa), ukujikeleza okuthile αd20 = 1.4609. Incibilika ku-organic solvents efana ne-ethanol, i-acetone, ether, chloroform kanye ne-benzen, incane kancane emanzini. Izinzile ngamakhemikhali futhi ingathathwa nge-Steam. I-Oral LD503.3G / KG / KG kumagundane, adi0-0.2mg / kg (FAO / WHO, 1994).
Ukusetshenziswa kwe-L-MeTH
(1) I-Menthol ingasetshenziswa njengokunambitheka okudliwayo, okusetshenziselwa amazinyo ikakhulukazi, uswidi, ukunambitheka okungezwa.
. Kwezokwelapha, kusetshenziswa njengezikhuthazayo, ezisebenza esikhunjeni noma esigabeni se-mucous, ngokupholisa nokuhleleka komphumela; Ngaphakathi, ingasetshenziswa njengomuthi wokuxosha umoya wekhanda nokuvuvukala kwempumulo, umphimbo kanye ne-larynx. I-Ester yayo isetshenziswa kwizinongo nemithi.
(3) isakhi esiyinhloko samafutha we-peppermint. Ngenxa yokunambitheka kwayo okucacisiwe kanye nomphumela wokupholisa, kusetshenziswa kabanzi kuswidi, izimonyo kanye namazinyo. Indlela yokukhiqiza ingahlanzwa kusuka kumafutha we-peppermint wemvelo noma kungahlanganiswa. Amafutha abalulekile atholwe yi-Steam Distillation yezingxenye ezingaphezulu (iziqu, amagatsha, amaqabunga kanye nama-inflorescence) we-mint emndenini weLabiatae abizwa nge-peppermint uwoyela, futhi isivuno sika-oyili singu-0.5-0.6. Izindlela Zokukhiqizwa ze-Menthol emincane
Uhlobo lwe-I-hlobo lutholakala kumafutha we-peppermint we-peppermint crude ngokupholisa, i-crystallization kanye nokwehlukana. Amafutha we-Peppermint aqukethe ubuchopho u-50% kuya ku-60%, apholile kuya ku-15 ℃, i-MentH ahlukaniswe nemvula yezulu, i-centrifugal, i-menhong bese ihlehliswa ukuya ku-5 ℃, bese ipholile amahlandla amathathu ziphakanyiswe ku-50% we-menthol (namanje ezansi cishe ngo-50% we-menthol). Kusuka ku-L-Menthol Ketone System L-menthol. Amafutha asele atholwe yindlela engenhla, ngaphansi kwengcindezi encishisiwe yokuthola ingcindezi ye-vaporize (cishe ama-20% kuya ku-25%), okusele nge-96% ethanol echithiwe, bese kuncishiswa ku-menthol nge-sodium yensimbi. Umkhiqizo wokwenziwa (i-DL-) ukhiqizwa kusuka kuma-aldehyde amnandi. Indlela yokukhiqiza i-Ment Uwoyela we-peppermint uwoyela uzoqandiswa ku-20 ° C, ukuhlukaniswa kwe-Crystalline Crude Menthol; Utshwala bomama buzophinde baqandwe buze kufike ku-40 ° C, bungahlukaniswa nengxenye ye-Crude Menthol. I-Crude Menthol yancibilika ngokushisa, icindezelekile ukususa amanzi, futhi yahlungwa ngenkathi kushisa. Ipholile cishe 0 ℃, i-7 ~ 9d, ihlukaniswe ne-crystallization, 42 ℃ yokomisa i-24h, yomile emazingeni okushisa aqediwe.

Imininingwane yenkampani

Imikhiqizo yokungenisa impahla eyinhloko yenkampani ifaka phakathi

. _ Ngenxa yalokho, izimilo ezisuselwa ku-polymer zingabizi kakhulu ekwenzeni. Ama-polymers angaphendula futhi ukuze ama-molekyuli ahlukene amakhemikhali angakwazi ukunamathisela ebusweni bokufakelwa, okwenza ukuthi ihambisane kakhulu nendawo yokudlela yomzimba.

(2) Ukwelashwa kwamanzi: Indlela yokulashwa kwamanzi ifaka ukwelashwa ngokomzimba kanye nokwelashwa kwamakhemikhali. Izindlela zokwelashwa kwamanzi zibe yiminyaka embalwa yomlando, izindlela zomzimba, kufaka phakathi ukusetshenziswa kosayizi obuhlukahlukene obuhlukile be-pore offiple, ukusetshenziswa kwe-adsorption noma indlela yokuvilapha, ukungcola kwamanzi ngaphandle, indlela ye-adsorption ku Okubaluleke kakhulu kwi-adsorption of carbon eyenziwe nge-carbon, i-barrier indlela yokudlula kwamanzi ngokusebenzisa impahla yokuhlunga, ukuze ukungcola ngosayizi omkhulu kungadlula, futhi ngaleyo ndlela thola amanzi ahlanzekile.

. _ _ Ukunambitheka: Ingxube yezinhlobonhlobo zamakha (kwesinye isikhathi futhi iqukethe inani elithile le-solvent) elihlanganiswe iphunga elithile, lingasetshenziswa ngokuqondile ngephunga elithile, lingasetshenziswa ngokuqondile kumakha athile, lingasetshenziswa kabanzi kumakha amakha, ama-cosmetics, ama-gels okugeza kanye nokunye nsuku zonke izidingo. Kalula nje, ukunambitheka kwenziwa ngenhlanganisela yamakha ahlukahlukene.
