methylene chloride 75 09 2 ua li cas?
Dichloromethane feem ntau yog tsim los ntawm chlorination ntawm methane. methane reacts nrog chlorine roj nyob rau hauv tshav kub los yog UV teeb, tsim methyl chloride, uas yog ntxiv chlorinated los tsim dichloromethane. Tom qab ntawd qhov sib xyaw ua ke yog sib cais los ntawm distillation kom cais dichloromethane.
DCM Ntau npaum li cas (75 09 2) Puas Toxic?
Lub toxicity ntawm methylene chloride nyob ntawm seb hom kev raug. Ob qho tib si nqus tau thiab noj tuaj yeem ua rau khaus khaus, nrog rau xeev siab thiab ntuav, txawm tias me me. Thaum ntau dua, nws tuaj yeem ua rau tuag taus.
Raws li EPA, muaj 85 tus neeg tuag los ntawm dichloromethane txij li xyoo 1980, feem ntau yog vim kev nqus pa hauv qhov chaw tsis zoo.
Hauv Tebchaws Europe, Pawg Saib Xyuas Kev Tshawb Fawb Txog Kev Ua Haujlwm Kev Ua Haujlwm Tsis Muaj Qhov Tseem Ceeb (SCOEL) pom zoo ib lub sijhawm - hnyav nruab nrab ntawm 100 feem ntawm ib lab (ppm) dhau 8 teev, nrog rau luv luv -lub sijhawm raug txwv (STEL) ntawm 200 rau 15 feeb.
Hauv Teb Chaws Asmeskas, Kev Tswj Xyuas Kev Nyab Xeeb thiab Kev Noj Qab Haus Huv (OSHA.gov) thiab Lub Tsev Haujlwm Saib Xyuas Kev Nyab Xeeb Hauv Lub Tebchaws rau Kev Ua Haujlwm Kev Nyab Xeeb thiab Kev Noj Qab Haus Huv (CDC.gov/NIOSH) tau teeb tsa cov kev txwv ntawm 25 ppm tshaj 8 teev lossis 125 ppm tshaj 15 feeb.
Dab tsi yog Lwm Txoj Kev rau methylene chloride 75 09 2?
Qee qhov kev xaiv rau methylene chloride (CAS 75-09-2) suav nrog cov kuab tshuaj tsis zoo xws liacetoneethanol,ethyl acetate hmoov, thiab methyl ethyl ketone.
