Intshayelelo

I-2,3-dimethyl-2-butene (i-DMB) i-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, iindlela zokwenza kunye nolwazi lokhuseleko:

 

Umgangatho:

Imbonakalo: I-DMB lulwelo olungenambala.

Ukunyibilika: Kunyibilika kwizinyibilikisi ezininzi eziphilayo ezifana ne-ethanol, ii-ethers, kunye neehydrocarbons.

Ubuninzi: Ubuninzi bayo bumalunga ne-0.68 g/cm³.

Ubutyhefu: I-DMB ayinayo ityhefu encinci, kodwa ukuvezwa okugqithisileyo kunokubangela ukucaphuka kwamehlo kunye nokucaphuka kolusu.

 

Sebenzisa:

I-Chemical synthesis: I-DMB isetyenziswa ngokuqhelekileyo kwi-organic synthesis njenge-solvent, ephakathi, okanye i-catalyst.

Ishishini lePetroleum: I-DMB iphinda isetyenziswe njengekhemikhali yesicelo esibalulekileyo kwi-jute petroleum refining kunye neenkqubo zepetrochemical.

 

Indlela:

I-DMB ilungiswa ngokuqhelekileyo nge-alkylation ye-methylbenzene kunye nepropylene. Amanyathelo athile abandakanya ukusabela kwe-methylbenzene kunye nepropylene kwiqondo lokushisa elifanelekileyo kunye noxinzelelo phambi kwe-catalyst yokuvelisa i-DMB.

 

Ulwazi ngoKhuseleko:

Njenge-solvent ye-organic, i-DMB iyaguquguquka. Ngethuba lokusetyenziswa, kuyimfuneko ukugcina umoya omhle kwaye ugweme ukubonakaliswa okugqithisileyo.

Inokubangela ukucaphuka xa udibana nolusu kunye namehlo. Ukudibana ixesha elide, ukuphefumla, okanye ukuginya kufuneka kuphetshwe.

Xa ugcina kwaye uphatha i-DMB, ukuphendula okune-oxidants eyomeleleyo kunye neeasidi ezomeleleyo kufuneka kuphetshwe.

Xa udibana nale nto, hlambulula ngokukhawuleza indawo yesikhumba engcolileyo okanye amehlo ngamanzi amaninzi kwaye ufune unyango.
