Chemical Properties:

I-methylene chloride isabela ngokuqinile ngezinsimbi ezisebenzayo ezifana ne-potassium, i-sodium, ne-lithium, nezisekelo eziqinile, isibonelo, i-potassium tert-butoxide. Kodwa-ke, inhlanganisela ayihambisani ne-caustics eqinile, ama-oxidizer aqinile, nezinsimbi ezisebenza ngamakhemikhali njengezimpushana ze-magnesium ne-aluminium.
Kuyaphawuleka ukuthi i-methylene chloride ingahlasela ezinye izinhlobo zokumboza, ipulasitiki, nerabha. Ngaphezu kwalokho, i-dichloromethane isabela nge-oxygen ewuketshezi, ingxubevange ye-sodium-potassium, ne-nitrogen tetroxide. Lapho ingxube ihlangana namanzi, igqwala ezinye izinsimbi ezingenasici, i-nickel, ithusi kanye nensimbi.
Uma ichayeke ekushiseni noma emanzini, i-dichloromethane izwela kakhulu njengoba ingaphansi kwe-hydrolysis esheshiswa ukukhanya. Ngaphansi kwezimo ezijwayelekile, izixazululo ze-DCM ezifana ne-acetone noma i-ethanol kufanele zizinzile amahora angu-24.
I-methylene chloride ayiphenduli ngezinsimbi ze-alkali, i-zinc, ama-amine, i-magnesium, kanye nama-alloys e-zinc ne-aluminium. Uma ihlanganiswe ne-nitric acid noma i-dinitrogen pentoxide, inhlanganisela ingaqhuma ngamandla. I-Methylene chloride iyasha uma ixutshwe nomhwamuko we-methanol emoyeni.
Njengoba inhlanganisela ingaqhuma, kubalulekile ukugwema izimo ezithile ezifana nezinhlansi, izindawo ezishisayo, amalangabi avulekile, ukushisa, ukukhishwa okumile, neminye imithombo yokuthungela.

Isicelo:

1, Isetshenziselwa ukufutha okusanhlamvu kanye nesiqandisi sefriji enengcindezi ephansi kanye nedivayisi yokupholisa umoya.
2. Isetshenziswa njenge-solvent, i-extractant, i-mutagen.
3, Isetshenziswa embonini ye-elekthronikhi. Ngokuvamile isetshenziswa njenge-ejenti yokuhlanza kanye ne-de-greasing.
4, Isetshenziswa njengezibulala-zinzwa zendawo zamazinyo, i-ejenti eqandisayo, i-ejenti yokucisha umlilo, ukuhlanza upende ongaphezulu wensimbi kanye ne-ejenti yokwehlisa amafutha.
5. Isetshenziswa njengama-organic synthesis intermediates.
