D-menthol CAS 15356-70-4 Cov ntaub ntawv
Lub cev
Qhov tsos thiab tsis hnov tsw: Nyob rau hauv chav tsev kub thiab siab, D-menthol nthuav tawm raws li ib tug tsis muaj xim thiab pob tshab koob zoo li siv lead ua, nrog ib tug nplua nuj thiab refreshing mint aroma, uas yog heev recognizable thiab yog tus kos npe tshuaj tsw qab ntawm peppermint khoom. Nws siv lead ua morphology ua rau nws ruaj khov thaum lub sijhawm cia thiab tsis yooj yim rau deform thiab adhesion.
Solubility: Nws muaj tsis zoo solubility nyob rau hauv dej, raws li lub hauv paus ntsiab lus ntawm "zoo solubility", nws yog yooj yim soluble nyob rau hauv organic solvents xws li ethanol, ether, chloroform, thiab lwm yam. Piv txwv li, nyob rau hauv cov khoom uas siv cawv raws li cov kuab tshuaj xws li perfumes thiab cov khoom siv tu tawv nqaij, D-menthol tuaj yeem ua kom tawg tau zoo thiab yaj, thiab cov ntxhiab tsw txias yog sib npaug. tso tawm.
Melting thiab boiling point: Melting point 42 - 44 ° C, boiling point 216 ° C. Lub melting point range qhia meej txog qhov kev hloov pauv ntawm nws lub xeev ntawm qhov teeb meem nyob ze ntawm chav tsev kub, thiab nws tuaj yeem yaj mus rau hauv cov kua hauv lub xeev me ntsis siab dua qhov kub ntawm chav tsev, uas yooj yim rau kev ua haujlwm tom ntej. Qhov kub siab dua ua kom ntseeg tau tias nws tuaj yeem nyob ruaj khov thiab tsis ua rau poob qis hauv cov pa distillation thiab lwm yam kev sib cais thiab kev ua kom huv.
Cov khoom siv tshuaj
Cov tshuaj tiv thaiv Redox: Raws li kev haus cawv, D-menthol tuaj yeem oxidized los ntawm cov tshuaj oxidizing muaj zog, xws li acidic potassium permanganate tov, los tsim cov ketone los yog carboxylic acid derivatives. Raws li kev txo qis me me, nws yog qhov ruaj khov, tab sis nrog cov khoom siv hluav taws xob tsim nyog thiab cov khoom siv hydrogen, nws cov ntawv cog lus tsis txaus ntseeg muaj peev xwm ua tau hydrogenated thiab hloov cov molecular saturation.
Esterification cov tshuaj tiv thaiv: Nws muaj hydroxyl kev ua haujlwm siab, thiab nws yooj yim rau esterify nrog cov organic acids thiab inorganic acids los tsim ntau yam menthol esters. Cov menthol esters no tsis tsuas yog khaws lawv cov khoom cua txias xwb, tab sis kuj hloov lawv cov aroma persistence thiab cov tawv nqaij-phooj ywg vim yog kev taw qhia ntawm ester pawg, thiab feem ntau yog siv hauv cov tshuaj tsw qab blending.
4. Qhov chaw thiab kev npaj
Ntuj qhov chaw: Ntau tus mint nroj tsuag, xws li Asian mint, spearmint mint, los ntawm cov nroj tsuag extraction, siv cov organic solvent extraction, chav distillation thiab lwm yam txheej txheem, cov mint nplooj nyob rau hauv enrichment, sib cais, kom tau tej yam ntuj tso khoom, nyiam los ntawm kev nrhiav cov khoom xyaw ntuj ntawm cov neeg siv khoom.
Chemical synthesis: D-menthol nrog rau qhov tshwj xeeb peb-dimensional configuration yuav raug tsim los ntawm asymmetric synthesis, catalytic hydrogenation thiab lwm yam complex zoo tshuaj txoj kev siv terpenoids haum raws li cov ntaub ntawv pib, uas muaj peev xwm ua tau raws li cov kev xav tau ntawm loj-scale industrial ntau lawm thiab tsim. rau qhov tsis muaj natural yield.
siv
Kev lag luam khoom noj khoom haus: Raws li cov khoom noj ntxiv, nws tau siv dav hauv cov pos hniav, khoom qab zib, dej qab zib thiab lwm yam khoom, muab nws saj txias, stimulating saj receptors, coj ib tug refreshing thiab qab ntxiag noj kev paub, thiab zoo heev txhim kho cov attractiveness ntawm cov khoom. nyob rau lub caij ntuj sov.
Cov tshuaj lom neeg txhua hnub: Hauv cov khoom siv tshuaj niaj hnub xws li tshuaj txhuam hniav, tshuaj ntxuav qhov ncauj, cov khoom tu tawv nqaij, tshuaj zawv plaub hau, thiab lwm yam, D-menthol ntxiv, uas tuaj yeem tsis tsuas yog ua kom lub siab los ntawm kev hnov tsw, tab sis kuj ua rau muaj kev xav zoo siab rau cov neeg siv vim yog txias hnov tsw ua los ntawm kev sib cuag nrog daim tawv nqaij thiab mucous daim nyias nyias, thiab npog li cov ntxhiab tsw phem.
Kev siv tshuaj: Kev siv tshuaj pleev xim rau kev npaj muaj D-menthol tuaj yeem ua kom txias thiab tshuaj loog rau ntawm daim tawv nqaij, txo qhov khaus thiab mob me ntsis ntawm daim tawv nqaij; Cov menthol qhov ntswg tee kuj tuaj yeem txhim kho qhov ntswg qhov ntswg thiab txo qhov congestion thiab o ntawm qhov ntswg mucosa.
