D-menthol CAS 15356-70-4 Ruzivo
Zvenyama
Chitarisiko uye kunhuwa: Pakamuri tembiricha uye kumanikidzwa, D-menthol inopa sekristaro isina ruvara uye yakajeka tsono, ine yakapfuma uye inozorodza mint inonhuhwirira, ino zivikanwa zvakanyanya uye ndiyo siginecha inonhuwira inonhuhwirira yezvigadzirwa zvepeppermint. Yayo crystal morphology inoita kuti igadzikane panguva yekuchengetera uye isiri nyore kukanganisa uye kunamatira.
Solubility: Iine kunyungudika kwakashata mumvura, ichitevera musimboti we "kunyungudika kwakafanana", inonyungudika nyore nyore muzvinonyungudutsa zveorganic senge ethanol, ether, chloroform, nezvimwewo semuenzaniso, mune zvigadzirwa zvinoshandisa doro sechinhu chinonyungudutsa senge mapefiyumu uye zvigadzirwa zvekuchengetedza ganda, D-menthol inogona kunyatsoparadzirwa nekunyungudutswa, uye kunhuhwirira kunotonhorera. inosunungurwa zvakaenzana.
Mapoinzi ekunyunguduka uye ari kufashaira: Kunyunguduka 42 – 44 °C, kuvira 216 °C. Iyo yekunyungudika inojekesa mamiriro ekuchinja kwemamiriro ayo ezvinhu padyo nekamuri tembiricha, uye inogona kunyungudutswa kuita yemvura yakakwira zvishoma pane tembiricha yekamuri, iri nyore kune inotevera kugadzirwa. Nzvimbo yepamusoro yekubikira inova nechokwadi chekuti inogona kuvapo yakadzikama uye isingaite kurasikirwa nekusagadzikana mune yakajairwa distillation uye mamwe mabasa ekuparadzanisa nekuchenesa.
Chemical properties
Redox reaction: Sedoro, D-menthol inogona kuiswa oxidized neakasimba oxidizing agent, senge acidic potassium permanganate solution, kugadzira ketone inoenderana kana carboxylic acid derivatives. Pasi pemamiriro ekuderedza zvinyoro, inenge yakagadzikana, asi neine catalyst yakakodzera uye hydrogen sosi, zvisungo zvayo zvisina kuvharwa zvine hunyanzvi hwekuve hydrogenated uye kushandura kuzara kwema molecular.
Esterification reaction: Iine yakakwira hydroxyl chiitiko, uye iri nyore kuita esterify ne organic acids uye inorganic acids kugadzira akasiyana menthol esters. Iyi menthol esters haingochengetedzi kutonhora kwayo chete, asiwo inoshandura kunhuhwirira kwavo uye kushamwaridzana kweganda nekuda kwekuiswa kwemapoka ester, uye inowanzoshandiswa mukunhuhwirira kusanganiswa.
4. Kwakabva uye kugadzirira
Natural source: Nhamba huru yemiti mint, yakadai seAsia mint, spearmint mint, kuburikidza nekuchera chirimwa, kushandiswa kweiyo organic solvent extract, steam distillation uye mamwe maitiro, iyo mint inosiya mukupfumisa, kupatsanura, kuti uwane zvigadzirwa zvemhando yepamusoro. inofarirwa nekutsvaga kwezvinhu zvakasikwa zvevatengi.
Kemikari synthesis: D-menthol ine chaiyo-matatu-dimensional kumisikidza inogona kuvakwa nenzira kwayo kuburikidza neasymmetric synthesis, catalytic hydrogenation uye dzimwe dzakaomarara nzira dzemakemikari dzinoshandisa akakodzera terpenoids sezvinhu zvekutanga, izvo zvinogona kusangana nezvinodiwa zvehukuru-hukuru kugadzirwa kwemaindasitiri uye kugadzira. nokuda kwokushayiwa zvibereko zvechisikigo.
use
Indasitiri yechikafu: Sekuwedzera kwechikafu, inoshandiswa zvakanyanya mukucheka chingamu, zvihwitsi, zvinwiwa uye zvimwe zvigadzirwa, ichipa kuravira kunotonhorera, inosimudzira kuravira zvinogamuchira, kuunza inozorodza uye inonakidza chiitiko chekudya, uye kuwedzera zvakanyanya kunaka kwechigadzirwa. muzhizha rinopisa.
Zuva nezuva makemikari munda: Mumazuva ese emakemikari zvigadzirwa senge mushonga wemazino, muromo, zvigadzirwa zvekuchengetedza ganda, shampoo, nezvimwe, D-menthol inowedzerwa, iyo isingangogone kuzorodza pfungwa nekunhuhwirira, asi zvakare inounza manzwiro anozorodza pakarepo kune vashandisi nekuda kwe kutonhora kwekunzwa kunogadzirwa nekusangana neganda uye mucous membranes, uye kuvhara kunhuhwirira kwakashata.
Mishonga inoshandiswa: Kushandiswa kwepamusoro kwemishonga ine D-menthol inogona kuunza kutonhora uye anesthetic effect pamusoro peganda, kubvisa kuputika uye kurwadziwa zvishoma paganda; Iyo menthol nasal madonhwe anogona zvakare kunatsiridza kufema kwemhino uye kuderedza kuungana uye kuzvimba kwenasal mucosa.
