Isingeniso

I-2,3-dimethyl-2-butene (DMB) iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:

 

Ikhwalithi:

Ukubukeka: I-DMB iwuketshezi olungenambala.

Ukunyibilika: Kuncibilika kuzincibilikisi eziningi eziphilayo njenge-ethanol, ama-ether, nama-hydrocarbon.

Ukuminyana: Ukuminyana kwayo kucishe kube ngu-0.68 g/cm³.

Ubuthi: I-DMB ayinabo ubuthi obuncane, kodwa ukuchayeka ngokweqile kungase kubangele ukucasuka kwamehlo nokucasuka kwesikhumba.

 

Sebenzisa:

I-Chemical synthesis: I-DMB ivamise ukusetshenziswa ku-organic synthesis njenge-solvent, i-intermediate, noma i-catalyst.

Imboni kaphethiloli: I-DMB iphinde isetshenziswe njengekhemikhali esetshenziswayo ebalulekile ku-jute petroleum refining kanye nezinqubo ze-petrochemical.

 

Indlela:

I-DMB ilungiswa ngokujwayelekile nge-alkylation ye-methylbenzene ne-propylene. Izinyathelo ezithile zibandakanya ukusabela kwe-methylbenzene ne-propylene ezingeni lokushisa elifanele kanye nengcindezi phambi kwe-catalyst ukuze kukhiqizwe i-DMB.

 

Ulwazi Lokuphepha:

Njengesincibilikisi esiphilayo, i-DMB iyaguquguquka. Ngesikhathi sokusebenzisa, kuyadingeka ukugcina umoya omuhle futhi ugweme ukuchayeka ngokweqile.

Ingabangela ukucasuka lapho ithinta isikhumba namehlo. Ukuthintana isikhathi eside, ukuhogela umoya, noma ukugwinya kufanele kugwenywe.

Lapho ugcina futhi uphatha i-DMB, ukusabela okunama-oxidants aqinile nama-asidi aqinile kufanele kugwenywe.

Uma uthinta le nto, hlambulula ngokushesha indawo yesikhumba engcolile noma amehlo ngamanzi amaningi futhi ufune usizo lwezokwelapha.
