Puas yog dimethyl sulfoxide soluble hauv dej?
Dimethyl sulfoxide (DMSO) yog soluble hauv dej thiab miscible nrog dej hauv txhua qhov kev faib ua feem. Nws yog ib qho polar heev, tsis yog -protonic hnyav. Cov qauv molecular ntawm DMSO endows nws muaj zog polarity thiab hydrophilicity. Nyob rau hauv chav tsev kub, nws yog kiag li miscible nrog dej nyob rau hauv ib tug ratio, tsim ib homogeneous, pob tshab kua.
Dab tsi yog qhov zoo ntawm dimethyl sulfoxide ua cov kuab tshuaj?
- High polarity: dimethyl sulfoxide muaj cov polarity siab, ua kom nws yaj ntau cov polar thiab nonpolar tebchaw, yog li nrhiav kev siv dav hauv tshuaj lom neeg thiab kev sib cais.
- Solubility zoo heev: DMSO nthuav tawm zoo heev solubility rau ntau cov organic thiab inorganic tshuaj, txhawb kev loj hlob ntawm ntau hom tshuaj tiv thaiv.
- Ruaj khov: Dimethyl sulfide nthuav tawm cov tshuaj lom neeg ruaj khov, tiv thaiv cov tshuaj tiv thaiv yooj yim thiab ua kom siv ntev ntev raws li cov kuab tshuaj.
- Tsawg viscosity: Piv nrog rau lwm cov kuab tshuaj, DMSO muaj viscosity qis dua, txo cov tshuaj viscosity thiab txhim kho fluidity los pab txhawb cov tshuaj tiv thaiv.
- Kev Npaj Yooj Yim: Kev sib xyaw ntawm DMSO yog qhov ncaj ncaj, ua tiav los ntawm kev sib ntxiv ntawm hydrogen sulfide thiab sulfur dioxide, nrog cov txheej txheem uas yooj yim los tswj.
