D-menthol CAS 15356-70-4 Zambiri

Zakuthupi
Mawonekedwe ndi fungo: Pa kutentha ndi kupanikizika, D-menthol imawoneka ngati kristalo wopanda mtundu komanso wowonekera ngati singano, wokhala ndi fungo lonunkhira la timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timadzi tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono timakhala tating'ono ting'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono ting'onoting'ono tomwe timatulutsa fungo la peppermint. Maonekedwe ake a kristalo amapangitsa kuti ikhale yokhazikika panthawi yosungidwa komanso kuti ikhale yosavuta kufooketsa ndi kumamatira.
Kusungunuka: Lili ndi kusungunuka kosauka m'madzi, motsatira mfundo ya "solubility yofanana", imasungunuka mosavuta mu zosungunulira za organic monga ethanol, etha, chloroform, ndi zina zotero. Mwachitsanzo, muzinthu zomwe zimagwiritsa ntchito mowa ngati zosungunulira monga mafuta onunkhira ndi zinthu zosamalira khungu, D-menthol imatha kumwazikana ndikusungunuka, komanso kununkhira koziziritsa. imatulutsidwa mofanana.
Kusungunuka ndi kuwira: Malo osungunuka 42 - 44 °C, malo otentha 216 °C. Kusungunuka kwa malo osungunuka kumamveketsa bwino za kusintha kwa zinthu zomwe zimakhala pafupi ndi kutentha kwa chipinda, ndipo zimatha kusungunuka mumadzimadzi okwera pang'ono kusiyana ndi kutentha kwa chipinda, chomwe chiri choyenera kukonzedwanso. Malo otentha okwera amatsimikizira kuti akhoza kukhalapo mokhazikika ndipo samakonda kutayika kosasunthika mu distillation wamba ndi ntchito zina zolekanitsa ndi zoyeretsa.

Mankhwala katundu
Redox reaction: Monga mowa, D-menthol imatha kuwotchedwa ndi oxidizing agent, monga acidic potassium permanganate solution, kuti apange ketone kapena carboxylic acid zotumphukira. Pansi pamikhalidwe yochepetsetsa, imakhala yokhazikika, koma yokhala ndi chothandizira choyenera ndi gwero la haidrojeni, zomangira zake zopanda unsaturated mwakuti zimatha kukhala hydrogenated ndikusintha kuchuluka kwa maselo.
Esterification reaction: Imakhala ndi zochita zambiri za hydroxyl, ndipo ndiyosavuta kuyipanga ndi ma organic acid ndi ma inorganic acid kuti ipange ma menthol esters osiyanasiyana. Ma menthol ester awa samangokhala ndi zinthu zoziziritsa, komanso amasintha kununkhira kwawo komanso kukhazikika pakhungu chifukwa choyambitsa magulu a ester, ndipo nthawi zambiri amagwiritsidwa ntchito pophatikiza kununkhira.
4. Gwero ndi kukonzekera
Gwero lachilengedwe: Mitengo yambiri ya timbewu tonunkhira, monga timbewu tating'onoting'ono ta Asia, timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu ta timbewu timapanga timbewu tating'onoting'ono, kugwiritsa ntchito organic zosungunulira m'zigawo, nthunzi distillation ndi njira zina, ndi timbewu masamba kulemeretsa, kulekana, kupeza zachilengedwe khalidwe mankhwala, kukondedwa ndi kufunafuna zinthu zachilengedwe za ogula.
Kaphatikizidwe ka Chemical: D-menthol yokhala ndi kasinthidwe katatu-dimensional imatha kupangidwa molondola kudzera mu kaphatikizidwe ka asymmetric, catalytic hydrogenation ndi njira zina zovuta zama mankhwala pogwiritsa ntchito ma terpenoids oyenera ngati zida zoyambira, zomwe zimatha kukwaniritsa zosowa zamafakitale akuluakulu ndikupanga chifukwa chosowa zokolola zachilengedwe.

ntchito
Makampani azakudya: Monga chowonjezera cha chakudya, chimagwiritsidwa ntchito kwambiri pakutafuna chingamu, maswiti, zakumwa zozizilitsa kukhosi ndi zinthu zina, kuwapatsa kukoma koziziritsa, zopatsa chidwi zolandilira kukoma, kubweretsa chakudya chotsitsimula komanso chosangalatsa, komanso kukulitsa kukopa kwa zinthuzo. m’chilimwe chotentha.
Munda wamankhwala watsiku ndi tsiku: Muzinthu zatsiku ndi tsiku monga mankhwala otsukira mkamwa, zotsukira mkamwa, zosamalira khungu, shampu, ndi zina zotere, D-menthol amawonjezeredwa, zomwe sizimangotsitsimula malingaliro ndi fungo, komanso kubweretsa chisangalalo kwa ogwiritsa ntchito nthawi yomweyo. kuzirala kutengeka opangidwa ndi kukhudzana ndi khungu ndi mucous zimagwira ntchito zosiyanasiyana, ndi kubisa fungo loipa.
Kugwiritsa ntchito mankhwala: Kugwiritsa ntchito pamutu kwa mankhwala okhala ndi D-menthol kumatha kutulutsa kuziziritsa komanso kukomoka pakhungu, kuchepetsa kuyabwa ndi kupweteka pang'ono pakhungu; Madontho a m'mphuno a menthol amathanso kusintha mpweya wabwino wa m'mphuno ndi kuchepetsa kusokonezeka ndi kutupa kwa mucosa yamphuno.
