Solubeness: hiki ʻole ke hoʻoheheʻe ʻia i ka wai a hiki ke hoʻoheheʻe ʻia i ka phenol, aldehyde, ketone, glacial acetic acid, triethyl phosphate, ethyl acetoacetate, a me cyclohexane; kāwili a hoʻoheheʻe me nā waihā koloke hydrocarbon solvent ethyl waiʻona, diethyl ether, a me N, N-dimethylformamide;    

ʻO ke kūpaʻa: I ka mahana maʻamau (ke ana wela o ka lumi) a ke ʻaʻohe ona mau, ʻoi aku ka paʻa o ka dichloromethane ma mua o nā mea like (chloroform a me carbon tetrachloride);
Hoʻohuli hopena: Inā pili ka wai i kahi manawa lōʻihi, e lohi mālie ia a hana i ka hydrogen chloride;  
ʻO ka polymerization weliweli: ʻaʻole e hiki

Ke kumu o ka dichloromethane:
Hiki i ka Dichloromethane ke hoʻopau loa a haʻahaʻa i ka ʻawahia; pili nui ia i ka hana ʻana i ke kiʻi ʻoniʻoni palekana a me Makrolon; Hoʻohana ʻia ke koena no ka mea hoʻoheheʻe pena, mea hoʻohaʻahaʻa metala, uahi a me ka ʻenekini hoʻowali kinoea, agena puhi polyurethane, mea hoʻokuʻu hoʻokuʻu a me ka mea hoʻoneʻe pena;

ʻO Dichloromethane kahi wai kala ʻole. Hoʻohana ʻia ia ma ke ʻano he ʻano hana i loko o ka hale kūʻai lāʻau lapaʻau a noi ʻia i ka hoʻomākaukau ʻana o penbritin, carbenicillin, cephalosporin, a pēlā aku, i ka mea hoʻoheheʻe no ka hana kiʻiʻoniʻoni, aila dewaxing mea hoʻoheheʻe, aerosol propellant, ʻenehana synthesion extraction agents, polyurethane a me nā ʻāpana ʻehu ʻē aʻe a me mea hoʻomaʻemaʻe metala i ka wā o ka hana ʻana i ka plastic foamed.
