Qhov sib txawv tseem ceeb ntawm DMSO thiab MSM yog DMSO yog ib qho organosulfur compound uas muaj nyob rau hauv cov kua theem, whereas MSM yog ib qho organosulfur compound uas muaj nyob rau hauv cov khoom theem.
Lub sij hawm DMSO sawv cev rau dimethyl sulfoxide thaum lub sij hawm MSM stands rau methylsulfonylmethane. Ob qho no yog organosulfur compounds. Qhov ntawd txhais tau tias; cov tebchaw no muaj sulfur atoms khi rau cov organic tebchaw. Qhov sib txawv loj ntawm DMSO thiab MSM yog nyob rau theem ntawm cov teeb meem uas cov ntsiab lus muaj nyob rau hauv chav tsev kub. Muaj qee qhov sib txawv thiab ntxiv rau qhov sib txawv tseem ceeb no.
DMSO yog dab tsi?
DMSO yog dimethyl sulfoxide. Nws yog ib qho organosulfur compound uas muaj nyob rau hauv cov kua theem ntawm chav tsev kub. Cov tshuaj formula rau DMSO yog (CH3)2SO. Cov tshuaj no yog cov kua tsis muaj xim uas yog ib qho tseem ceeb raws li cov kuab tshuaj polar aprotic, piv txwv li, nws tuaj yeem yaj ob qho tib si polar thiab nonpolar tebchaw rau qee qhov. Yog li ntawd, qhov sib xyaw no yog miscible nrog ntau yam sib txuas. Nws qhov hnyav yog 78.13 g / mol. Lub melting point ntawm no compound yog kuj siab (19 ° C). Feem ntau, DMSO muaj qej zoo li saj hauv qhov ncauj.
Thaum xav txog cov qauv tshuaj, DMSO muaj trigonal pyramidal geometry. Nws yog vim hais tias nws muaj sulfur atom ntawm qhov chaw nrog ib leeg electron khub ntawm nws thiab ob pawg methyl thiab ib qho oxygen atom txuas rau sulfur atom. Hauv kev lag luam nplai, peb siv dimethyl sulfide rau kev tsim DMSO raws li cov khoom lag luam ntawm cov txheej txheem Kraft.
Daim duab 01: Cov Qauv Tshuaj ntawm DMSO
DMSO tsis muaj zog acidic vim tias pawg methyl ntawm cov tshuaj no tsis muaj zog acidic. Rau cov electrophiles mos, DMSO yog nucleophilic. Tsis tas li ntawd, qhov sib xyaw no tseem siv tau los ua oxidant hauv cov organic synthesis cov tshuaj tiv thaiv. Hauv kev sib koom ua ke chemistry, DMSO yog ib qho ligand.
DMSO muaj ntau yam kev siv, suav nrog nws siv cov polar aprotic hnyav uas tuaj yeem yaj ob qho tib si polar thiab nonpolar compounds, txhawm rau tiv thaiv cov txheej txheem thib ob uas tsim ntawm DNA template thaum PCR, ua lwm yam tshuaj, thiab lwm yam.
MSM yog dab tsi?
MSM yog methylsulfonylmethane. Nws yog ib qho organosulfur compound uas muaj nyob rau hauv cov khoom theem ntawm chav tsev kub. Cov tshuaj formula yog (CH3)2SO2 Cov tshuaj no suav tias yog tshuaj lom neeg tsis muaj zog.. Nws ib txwm tshwm sim hauv qee cov zaub mov, cov nroj tsuag thaum ub, dej haus, thiab lwm yam. Nws qhov hnyav yog 94.13 g / mol. Lub melting point yog 109 ° C. Tsawg los yog tsis muaj reactivity ntawm MSM yog vim oxidation lub xeev ntawm cov sulfur atom; nws twb nyob hauv lub xeev oxidation siab tshaj plaws uas nws tuaj yeem nyob.
Daim duab 02: Cov qauv tshuaj ntawm MSM
Thaum xav txog kev siv cov tshuaj no, nws yog siv los ua cov kuab tshuaj vim nws cov polarity thiab thermal stability; nws muaj daim ntawv thov kev kho mob thiab kev noj haus ib yam nkaus.
Qhov txawv ntawm DMSO thiab MSM yog dab tsi?
Lub sij hawm DMSO sawv cev rau dimethyl sulfoxide thaum lub sij hawm MSM stands rau methylsulfonylmethane. Ob qho no yog organosulfur compounds. Qhov sib txawv tseem ceeb ntawm DMSO thiab MSM yog DMSO yog ib qho organosulfur compound uas muaj nyob rau hauv cov kua theem, whereas MSM yog ib qho organosulfur compound uas muaj nyob rau hauv cov khoom theem. Ntxiv mus, DMSO yog polar aprotic; Yog li, nws tuaj yeem yaj ob qho tib si polar thiab nonpolar compounds. Txawm li cas los xij, MSM yog qhov sib xyaw ua ke. Thaum xav txog cov geometry ntawm cov molecules, DMSO muaj ib tug trigonal pyramidal qauv thaum MSM muaj ib tug trigonal planar qauv.
Hauv qab infographic qhia txog qhov sib txawv ntawm DMSO thiab MSM.
Summary – DMSO vs MSM
Lub sij hawm DMSO sawv cev rau dimethyl sulfoxide thaum lub sij hawm MSM stands rau methylsulfonylmethane. Ob qho no yog organosulfur compounds. Txawm li cas los xij, qhov sib txawv tseem ceeb ntawm DMSO thiab MSM yog DMSO yog ib qho organosulfur compound uas muaj nyob rau hauv cov kua theem, whereas MSM yog ib qho organosulfur compound uas muaj nyob rau hauv cov khoom theem.
