2,3-Dimethyl-2-butene(CAS#563-79-1)
Iikhowudi zoMngcipheko | I-R11 – Iyatsha kakhulu I-R65 – Inobungozi: Inokubangela umonakalo emiphungeni ukuba iginyiwe R36/37/38 – Ukucaphuka kwamehlo, inkqubo yokuphefumla kunye nolusu. I-R22 – Iyingozi xa iginyiwe I-R19 – Isenokwenza iiperoxide ezidubulayo R40 – Ubungqina obuncinane besiphumo somhlaza R36/37 – Iyacaphukisa emehlweni nakwinkqubo yokuphefumla. |
Inkcazelo yoKhuseleko | S16 – Gcina kude kwimithombo yomlilo. S33 -Thatha amanyathelo okhuseleko ngokuchasene nokukhutshwa okungatshintshiyo. S62 – Ukuba iginyiwe, musa ukugabha; funa iingcebiso zonyango ngokukhawuleza kwaye ubonise esi sikhongozeli okanye ileyibhile. S9 – Gcina isikhongozeli kwindawo engenamoya. S36/37/39 – Nxiba iimpahla ezikhuselayo ezifanelekileyo, iiglavu kunye nokhuseleko lwamehlo/ubuso. S26 – Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango. S36/37 – Nxiba iimpahla ezifanelekileyo zokukhusela kunye neeglavu. |

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.
