Yintoni i-L-Menthol CAS 2216-51-5?

I-L-Menthol iikristale ezimile njengenaliti ezingenambala kunye nevumba elimnandi le-mint. Uxinzelelo olunxulumeneyo d1515=0.890, iqondo lokunyibilika 41~43℃, iqondo lokubilisa 216℃, 111℃ (2.67kPa), ukujikeleziswa okuthe ngqo kwe-optical αD Chemicalbook20=-49.3°, isalathisi serefractive nD20=1.4609. Inyibilika kwizinyibilikisi eziphilayo ezifana ne-ethanol, i-acetone, i-ether, i-chloroform kunye ne-benzene, kwaye i-soluble kancinane emanzini. Iimpawu zekhemikhali zizinzile kwaye zinokuguquka kunye nomphunga.

Isicelo

I-1.Menthol sisiqholo esityiwayo esivumelekileyo ukuba sisetyenziswe kwilizwe lam kwaye sisetyenziswa ikakhulu ukwenza intlama yamazinyo, iilekese kunye neziselo.
2.Zombini i-menthol kunye ne-racemic menthol zingasetyenziswa njenge-flavoring agents kwi-toothpaste, i-perfume, iziselo kunye neelekese. Isetyenziswe njengento evuselelayo kwiyeza, isebenze kwesikhumba okanye i-mucous membranes, kwaye inomphumela wokupholisa kunye ne-antipruritic; xa ithathwa ngomlomo, ingasetyenziselwa njenge-carminative yentloko kunye nokuvuvukala kweempumlo, i-pharynx, kunye ne-larynx. Ii-esters zayo zisetyenziselwa iziqholo kunye namayeza.
3.Icandelo eliphambili leoli yepeppermint. Ngenxa yencasa yayo ekhethekileyo ye-mint kunye nesiphumo sokupholisa, isetyenziswa kakhulu kwiilekese, izithambiso kunye nentlama yamazinyo.
