Tshuaj Tshuaj Muaj Zog:

Methylene chloride reacts muaj zog nrog cov khoom siv hlau xws li potassium, sodium, thiab Lithcacy, thiab muaj zog, potassium tert-butoxide. Txawm li cas los xij, cov compound yog incompatibatibatibatibatibatibatibat phim, muaj zog oxidizers, thiab cov hlau uas yog cov tshuaj muaj tshuaj xws li cov hmoov magnesium thiab txhuas.
Nws yog qhov tsis tseem ceeb uas methylene chloride tuaj yeem tua qee hom kev pleev xim, yas, thiab roj hmab. Ib qho ntxiv, dichloromethane reacts nrog cov pa oxygen, sodium-potassium alloy, thiab nitrogen tetroxide. Thaum cov kab sib txuas los rau hauv kev sib cuag nrog dej, nws corrodes ib co hlau hlau, npib tsib xee, tooj liab thiab hlau.
Thaum raug cua sov los yog dej, dichloromethane yuav rhiab heev raws li nws yog raug rau hydrolysis uas nrawm nrawm ntawm lub teeb. Nyob rau hauv ib txwm muaj mob, kev daws teeb meem ntawm dcm xws li acetone lossis ethanol yuav tsum ruaj khov rau 24 teev.
Methylene chloride tsis hnov ​​qab zib nrog cov makali metrals, zinc, amines, magnesium, ntxiv rau alloys ntawm zinc thiab txhuas. Thaum sib xyaw nrog nitric acid lossis dinitrogen pentoxide, qhov sib txuas tuaj yeem ua rau tawg. Methylene chloride yog nplaim taws thaum sib xyaw nrog Methanol vapor hauv huab cua.
Txij li thaum lub compound tuaj yeem tawg, nws yog ib qho tseem ceeb kom zam qee yam mob xws li cov kab hluav taws, kub tawm, cua sov, thiab lwm yam kev tawm tsam.

Daim Ntawv Thov:

1, siv rau cov hmoov nplej lis thiab tub yees ntawm cov freezer qis thiab cua txias.
2, siv raws li cov kuab tshuaj, extractant, mutagen.
3, siv hauv kev lag luam hluav taws xob. Feem ntau siv raws li tu thiab muaj cov neeg sawv cev.
4, siv los ua cov tshuaj loog hauv cheeb tsam ib cheeb tsam, khov tus neeg sawv cev, tua hluav taws tus neeg saib xyuas, cov xim hlau tu thiab kho cov neeg sawv cev.
5, siv los ua cov organic synthemes intermediates.
