Abubuwan Sinadarai:

Methylene chloride yana amsawa da ƙarfi tare da ƙarfe masu aiki kamar potassium, sodium, da lithium, da tushe mai ƙarfi, misali, potassium tert-butoxide. Duk da haka, fili bai dace ba tare da caustics masu ƙarfi, masu ƙarfi mai ƙarfi, da ƙarfe waɗanda ke aiki da sinadarai irin su magnesium da foda na aluminum.
Abin lura ne cewa methylene chloride zai iya kai hari ga wasu nau'ikan sutura, filastik, da roba. Bugu da ƙari, dichloromethane yana amsawa tare da oxygen ruwa, sodium-potassium alloy, da nitrogen tetroxide. Lokacin da mahadi ya haɗu da ruwa, yana lalata wasu bakin karfe, nickel, jan karfe da baƙin ƙarfe.
Lokacin da aka fallasa shi zuwa zafi ko ruwa, dichloromethane ya zama mai hankali sosai yayin da aka yi shi da hydrolysis wanda haske yake sauri. A ƙarƙashin yanayi na al'ada, mafita na DCM kamar acetone ko ethanol yakamata su kasance barga na awanni 24.
Methylene chloride baya amsawa tare da alkali karafa, zinc, amines, magnesium, kazalika da gami na zinc da aluminum. Lokacin da aka haɗe shi da nitric acid ko dinitrogen pentoxide, fili zai iya fashewa da ƙarfi. Methylene chloride yana ƙonewa lokacin da aka haɗe shi da tururin methanol a cikin iska.
Tun da fili na iya fashewa, yana da mahimmanci a guje wa wasu yanayi kamar tartsatsin wuta, filaye masu zafi, buɗe wuta, zafi, fiɗa a tsaye, da sauran hanyoyin kunna wuta.
