Dimethyl sulfate (tseem hu ua dimethyl methanedioate sulfate) yog cov kua tsis muaj xim. Nws cov khoom tseem ceeb muaj xws li:
- Solubility: soluble nyob rau hauv ntau cov organic solvents xws li cawv, ethers thiab aliphatic hydrocarbons.
- Stability: Zoo li ruaj khov ntawm chav tsev kub, tab sis cua sov rau qhov kub thiab txias los yog kev sib cuag nrog cov oxidizing muaj zog yuav ua rau muaj kev puas tsuaj.
Dimethyl sulfate yog siv dav hauv kev lag luam tshuaj, kev siv tseem ceeb suav nrog:
- Raws li tus neeg sawv cev acylating hauv cov organic synthesis thiab ua lub luag haujlwm tseem ceeb hauv kev tsim cov polyester fibers thiab yas.
- Raws li ib tug hnyav nyob rau hauv kev npaj ntawm pigments, resins thiab coatings.
- Siv nyob rau hauv kev tsim cov polyurethane ua npuas ncauj hloov tau rau cov khoom xws li lub txaj thiab lub rooj zaum hauv tsheb.
Kev ceev faj txog kev nyab xeeb yuav tsum tau ua thaum siv thiab tuav dimethyl sulphate:
- Dimethyl sulfate yog irritating thiab tej zaum yuav ua rau puas tsuaj rau daim tawv nqaij, qhov muag thiab ua pa system. Cov hnab looj tes tiv thaiv, tsom iav thiab cov khaub ncaws tiv thaiv tsim nyog yuav tsum hnav thaum tuav.
- Tsis txhob tiv tauj dimethyl sulphate nrog qhib nplaim taws lossis qhov chaw cua sov kom tsis txhob muaj hluav taws kub lossis tawg.
- Khaws cia deb ntawm qhov chaw ntawm qhov hluav taws kub thiab oxidising cov neeg ua hauj lwm nyob rau hauv ib qho chaw zoo -ventilated cheeb tsam thiab tsis txhob raug huab cua ntev.
- Pov tseg cov dimethyl sulphate raws li cov cai hauv zos thiab tsis txhob muab pov tseg lossis tso rau hauv ib puag ncig.
Thov ua tib zoo saib xyuas tshwj xeeb rau qhov tseeb tias Dimethyl Sulphate yog cov tshuaj lom thiab tsis haum tshuaj thiab yuav tsum tau siv raws li cov lus qhia kev nyab xeeb tsim nyog thiab ua raws li Daim Ntawv Qhia Txog Kev Nyab Xeeb Tshuaj rau cov ncauj lus kom ntxaws.
