KAYAMBIDWE:
Chidule:
Dimethyl sulfoxide (chidule cha DMSO) ndi mankhwala achilengedwe okhala ndi sulfure; formula ya molekyulu: (CH3) 2SO; Imawoneka ngati madzi opanda mtundu, opanda fungo, osalala komanso oyaka kutentha kwa chipinda. Ili ndi polarity yayikulu komanso malo otentha kwambiri. Ilinso ndi mawonekedwe a aprotic ndi osakanikirana ndi madzi. Ili ndi poizoni wochepa, kutentha kwabwino, ndipo siisakanikirana ndi paraffin. Imasungunuka m'madzi, ethanol, propanol, ether, benzene ndi chloroform ndi mitundu ina yambiri ya zinthu zachilengedwe ndipo imatchedwa "universal solvent." Ndi mankhwala wamba achilengedwe omwe ali ndi mphamvu yosungunuka kwambiri. Imatha kusungunula mankhwala ambiri achilengedwe kuphatikiza chakudya, ma polima, ma peptide, komanso mchere ndi mpweya wambiri wosapangidwa. Imatha kusungunula kuchuluka kwa solute komwe kulemera kwake kuli kofanana ndi 50-60% yokha (mankhwala ena wamba nthawi zambiri amasungunula 10-20%), kotero ndikofunikira kwambiri pakuyang'anira zitsanzo komanso kufufuza mwachangu mankhwala. Pazifukwa zina, kukhudzana pakati pa dimethyl sulfoxide ndi chloride kungayambitse kuphulika.

Kagwiritsidwe Ntchito
1. Ingagwiritsidwenso ntchito pochotsa arene, komanso ngati njira yochitira zinthu yomwe imagwiritsidwa ntchito popanga ma resin ndi utoto, komanso imagwiritsidwa ntchito pa acrylic polymerization ndi spinning solvent.
2. Itha kugwiritsidwa ntchito ngati organic solvent, reaction medium komanso pakati pa organic synthesis. Ndi yosinthasintha kwambiri. Chogulitsachi chili ndi mphamvu yosankha kwambiri yochotsera, ndipo chingagwiritsidwe ntchito ngati polymerization ndi condensation solvent ya acrylic resin ndi polysulfone resin, monga polymerization ndi spining solvent ya polyacrylonitrile ndi cellulose acetate, ngati solvent yochotsera yolekanitsa alkanes ndi arenes, komanso ngati reaction medium ya arenes, butadiene extraction, acrylic fiber, plastic solvents, organic and synthetic dyes, ndi ma pharmaceutical industry. Mu gawo la mankhwala, dimethyl sulfoxide ili ndi anti-inflammatory effect komanso analgesic effect yokhala ndi mphamvu yayikulu yolowera pakhungu, motero imatha kusungunula mankhwala ena ndikuwonjezera kulowa kwawo m'thupi la munthu kuti ikwaniritse zolinga zochizira. Kutenga katundu wonyamula wa dimethyl sulfoxide kungapangitse kuti igwiritsidwe ntchito ngati zowonjezera zophera tizilombo. Kuonjezera pang'ono dimethyl sulfoxide m'mankhwala ena ophera tizilombo kungathandize kuti mankhwala ophera tizilombo alowe m'chomera kuti apititse patsogolo kugwira ntchito. Dimethyl sulfoxide ingagwiritsidwenso ntchito ngati chosungunulira utoto, chochotsera utoto, komanso chonyamulira utoto wa ulusi wopangidwa. Ingagwiritsidwenso ntchito ngati choyamwitsa acetylene ndi sulfur dioxide yobwezeretsanso komanso chosinthira ulusi wopangidwa, choletsa kuzizira ndi capacitor dielectric, mafuta oletsa brake, ndi chotsitsa cha zitsulo zosowa.
3. Ingagwiritsidwe ntchito ngati zosungunulira zowunikira komanso chothandizira kukonza chromatography ya mpweya komanso chosungunulira chowunikira ma spectra a UV.
Kulongedza ndi Kutumiza
225KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
