DMSO ndi DMF: Mphamvu zamagetsi pamakampani

Dimethyl Sulfoxide (Dmbusa) ndi N,N-dimethlfermamide (DMF) onse ndi dipolar aprotic solvents ndi ofanana thupi katundu. DMSO ndi yocheperapo kuposa DMF, ndipo amatengedwa ngati m'malo otetezeka.

N,N-Dimethylformamide (DMF) ndi Dimethyl Sulfoxide (Dmbusa) ndi zosungunulira ziwiri zamphamvu zomwe zimagwira ntchito yofunika kwambiri pamakampani opanga mankhwala. Makhalidwe awo apadera, kusinthasintha, ndi ntchito zosiyanasiyana zimawapangitsa kukhala ofunikira kwambiri popanga mankhwala, mapulasitiki, Zolemba, ndi zinthu zina zambiri.

Kumvetsetsa N,N-Dimethylformamide (DMF):

N,N-Dimethylformamide ndi China N,Wopanga N-Dimethylformamide, omwe amadziwika kuti DMF, ndi organic pawiri wa banja amide. Nazi zinthu zake zazikulu ndi mawonekedwe ake:

Katundu:

1. Zopanda mtundu, hygroscopic madzi okhala ndi fungo labwino
2. Malo otentha kwambiri (153°C) ndi malo ozizirirapo otsika (-61°C)
3. Kusungunuka kwabwino kwamitundu yambiri yama organic ndi inorganic compounds
4. Polar aprotic zosungunulira ndi mkulu dielectric mosasinthasintha

Mapulogalamu:

1. Amagwiritsidwa ntchito kwambiri popanga ulusi wa polyurethane ndi kupanga
2. Amatumikira monga zosungunulira popanga mankhwala, utoto, ndi mankhwala ophera tizilombo
3. Amagwiritsidwa ntchito m'makampani opanga zamagetsi kuti azitsuka ndi kuchotsa mafuta
4. Amagwiritsidwa ntchito ngati sing'anga munjira zosiyanasiyana zama mankhwala

Kufufuza Dimethyl Sulfoxide (Dmbusa) mwa China Dimethyl Sulfoxide katundu:

Kapangidwe ka mankhwala: DMSO ili ndi magulu awiri a methyl omwe amamangiriridwa ku sulfur oxide (S=O). DMF ili ndi magulu awiri a methyl omwe amamangiriridwa ku atomu ya nayitrogeni yomwe imamangiriridwa ku gulu la formyl (C(=O)H).

Thupi katundu:

1. Malo otentha: DMSO ili ndi kuwira kwa 189 ° C, pamene DMF ili ndi kuwira kwa 153 ° C.
2. Mtundu: DMF ndi madzi opanda mtundu mpaka achikasu.
3. Kununkhira: DMF ili ndi fungo lodziwika bwino.
4. Kuchulukana: DMF ndi yocheperako pang'ono poyerekeza ndi madzi.
5. pophulikira: DMF ili ndi kung'anima kwa 136 ° F.

Mapulogalamu:

1. Amagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala monga zosungunulira komanso zowonjezera
2. Amagwiritsidwa ntchito popanga mapulasitiki, Zolemba, ndi zomatira
3. Amatumikira monga zosungunulira pakupanga utoto, zokutira, ndi inki
4. Amagwiritsidwa ntchito ngati cryoprotectant posungira zitsanzo zamoyo

Kuyerekeza Pakati pa DMSO Ndi DMF

Dmbusa: Atha kuperekedwa pakamwa, kudzera m'mitsempha, kapena pamutu. Itha kugwiritsidwanso ntchito ngati cryoprotectant ya minofu yamunthu.
DMF: Ndiwotulutsa bwino kuposa DMSO-acetone wa mitundu ya chlorococcalean.

Zolinga Zachitetezo Kwa Onse N,N-Dimethylformamide Ndi Dimethyl Sulfoxide

Ngakhale DMF ndi DMSO ndi zosungunulira zamtengo wapatali, ndikofunikira kuyika patsogolo njira zachitetezo pozigwira:

1. Mpweya wabwino: Onetsetsani mpweya wokwanira kuti mupewe mpweya wabwino.
2. Zida zoteteza: Valani zovala zoyenera zodzitetezera, magolovu, ndi kuteteza maso kuti achepetse kukhudzana ndi khungu.
3. Kusamalira Mosamala: Gwirani DMF ndi DMSO m'malo olowera mpweya wabwino kutali ndi komwe kumatentha komanso malawi otseguka.
4. Kusunga ndi Kutaya: Sungani zosungunulirazi m'mitsuko yotsekedwa mwamphamvu ndipo mutayire moyenera malinga ndi malamulo akumaloko.

Monga Kutsogolera China Benzene ogulitsa, HANGDACHEM imapereka mankhwala apamwamba kwa makasitomala akunja ndi mitengo yampikisano yogulitsa. Ngati mukuganiza kugula, chonde funsani nafe nthawi yomweyo.
