Kev piav qhia ntawm cov morphology ntawm dimethyl sulfoxide (DMSO):

Tsos: Tsis muaj xim, pob tshab los yog me ntsis daj kua.
Tsw: Tsis muaj ntxhiab los yog yuav luag tsis muaj ntxhiab.
Hygroscopicity: Nws muaj zog hygroscopicity thiab tuaj yeem nqus tau ntau dua 70% ntawm nws qhov hnyav ntawm dej.
Kev yaj: Nws tuaj yeem sib xyaw nrog dej thiab ethanol ntawm qhov xav tau, thiab tsis yaj hauv alkanes. Nws 2.16% aqueous kua yog isotonic nrog plasma.
Lwm yam ntxwv: Lub ntsiab lus khov ntawm cov kua dej yog qis heev, thiab lub ntsiab lus khov ntawm dej tuaj yeem txo qis rau -80 degrees ntawm qhov concentration ntawm 60%. Nws muaj ntau yam solubility thiab tuaj yeem yaj cov dej-soluble, rog-soluble thiab ntau yam tshuaj uas nyuaj rau yaj hauv lwm cov kuab tshuaj. Nws yog hu ua "universal solvent".
DMSO yog ib yam kua tsis muaj xim, pob tshab thaum sov li chav tsev. Nws muaj cov yam ntxwv tshwj xeeb ntawm lub cev thiab tshuaj lom neeg, uas ua rau nws siv dav hauv ntau qhov chaw.

Kev siv cov dimethyl sulfoxide (tshuaj lom neeg):

Cov kuab tshuaj thiab cov tshuaj tiv thaiv: Ua ib qho kuab tshuaj polar aprotic, nws tuaj yeem yaj ntau yam organic compounds thiab siv dav ua cov kuab tshuaj thiab cov tshuaj tiv thaiv hauv cov organic synthesis.
Cov ntawv thov tshuaj:
Tshuaj tiv thaiv kev o thiab analgesic: Nws muaj cov teebmeem tiv thaiv kev o thiab analgesic tseem ceeb thiab tuaj yeem siv los kho cov kab mob o xws li mob pob qij txha thiab gout thiab txo qhov mob.
Txhawb kev nkag mus rau hauv cov tshuaj: Vim nws qhov permeability, nws pab cov tshuaj nkag mus rau hauv tib neeg lub cev thiab feem ntau siv ua tus nqa tshuaj lossis diluent.
Cov Ntawv Thov Kev Lag Luam:
Kev zas xim thiab rov ua dua tshiab: siv ua cov tshuaj zas xim, cov tshuaj tshem tawm cov xim rau cov xov paj thiab cov dej nqus rau kev rov qab tau acetylene thiab sulfur dioxide.
Lwm tus: Nws kuj tseem siv rau hauv cov tshuaj ua los ntawm cov fiber ntau uas ua rau cov kua qaub ncaug sib xyaw, cov tshuaj thermoplastic high-strength polysulfone, thiab cov roj pleev xim kws tshuaj.
Vim nws cov khoom siv lub cev thiab tshuaj lom neeg tshwj xeeb, dimethyl sulfoxide tau pom tias muaj kev thov dav hauv ntau qhov chaw.
