Njirimara anụ ahụ na kemịkalụ: mmiri na-agbanwe agbanwe na-enweghị agba, dị ka isi nke ether na ụtọ.
Njupụta dị n'etiti: D4201.326Kg/L.
ebe esi mmiri: 40.4 DEG C.
Ebe agbaze: -96.7 degrees, ebe ọkụ nke 615 DEG C. A na-agbaze ntakịrị na mmiri, a na-agbaze na ethanol, ethyl ether, ihe na-egbu egbu, mkpali ọgwụ ọjọọ. Dichloromethane na mmeghachi omume hydrolysis mmiri, dichloromethane nwere ihe na-eme ka ihe kwụsie ike na azụmahịa, iji gbochie hydrolysis. Dichloromethane na oxygen dị elu ga-emepụta ngwakọta na-agbawa agbawa, mana ọ bụghị ihe na-ere ọkụ, a na-ejikarị ya eme ihe n'ụlọ ọrụ na-anaghị egbu egbu, ihe mgbaze na-anaghị ere ọkụ na obere ebe esi mmiri.

Ebumnuche
Maka ihe mgbaze na-anaghị ere ọkụ: nhicha ígwè, ihe na-ewepụ agba, ihe na-eme ka mmanụ ghara ire ọkụ, ihe na-agbaze cellulose acetate atọ; ihe nkiri, aerosol, ọgwụ nje na vitamin na mmepụta ihe mgbaze; ihe na-agba ụfụfụ maka imepụta plastik injinia; ngwaahịa ihe na-egbochi ire ọkụ; ejiri dochie ojiji F11 na F12 maka mmepụta ngwaahịa; ngwaahịa kemịkalụ dị mma.

Nkwakọ ngwaahịa, nchekwa na njem
Ngwugwu ihe eji eme ka ihe dị n'ime ya, nke e ji ígwè galvanized, drum ígwè ojii ma ọ bụ tank kpuchie, nke ruru pasentị iri asatọ, nwere ike inye nchebe nitrogen maka ndị ọrụ nwere ihe pụrụ iche achọrọ. A ga-echekwa ebe nchekwa ahụ n'ebe dị jụụ ma kpọọ nkụ, a ga-ekuru ikuku n'ụlọ nkwakọba ihe ahụ iji zere ịkpọtụrụ oke ikuku oxygen ma ọ bụ oxides, iji zere imetụ mmiri aka iji gbochie mmiri ịbanye n'ime ya. Ụgbọ njem ahụ ga-agbaso iwu nke Ndị China gbasara mbufe kemịkalụ dị ize ndụ site n'okporo ụzọ na ụgbọ okporo ígwè.
