Okwu mmalite

Diiodomethan. Ihe na-esonụ bụ mmalite nke njirimara, ojiji, ụzọ nkwadebe na ozi nchekwa nke diiodomethane:

 

Ogo:

Ọdịdị: Diiodomethane bụ mmiri mmiri na-acha odo odo na-enweghị ụcha nke nwere isi pụrụ iche.

Njupụta: Njupụta ahụ dị elu, ihe dịka 3.33 g/cm³.

Solubility: soluble na organic solvents dị ka alcohols na ethers, insoluble na mmiri.

Nkwụsi ike: O siri ike, mana ọ nwere ike mebie ya site na okpomọkụ.

 

Jiri:

Nnyocha kemịkalụ: Enwere ike iji Diiodomethane dị ka reagent n'ime ụlọ nyocha maka mmeghachi omume njikọ organic na nkwadebe nke ihe mkpali.

Ihe na-egbu egbu: Diiodomethane nwere ihe na-akpata nje na enwere ike iji ya dị ka ihe na-efe efe n'ọnọdụ ụfọdụ akọwapụtara.

 

Usoro:

Enwere ike ịkwado Diiodomethane site na:

Mmeghachi omume nke methyl iodide na ọla kọpa iodide: Methyl iodide na-emeghachi omume na ọla kọpa iodide iji mepụta diodomethane.

Methanol na ayodiin mmeghachi omume: methanol na-emeghachi omume na ayodiin, na methyl iodide emepụtara na-emeghachi omume na ọla kọpa iodide iji nweta diodomethane.

 

Ozi nchekwa:

Nsi: Diiodomethane na-akpasu iwe ma na-emebi akpụkpọ ahụ, anya, na usoro iku ume, ma nwee ike inwe mmetụta na usoro nhụjuanya nke etiti.

Usoro nchekwa: Yiri ugogbe anya nchebe, uwe aka na ihe mkpuchi gas mgbe ị na-eji hụ na gburugburu ụlọ nyocha nwere ikuku nke ọma.
