Selelekela

2,3-dimethyl-2-butene (DMB) ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa sebopeho sa eona, tšebeliso, mekhoa ea tlhahiso le tlhaiso-leseling ea polokeho:

 

Boleng:

Ponahalo: DMB ke mokelikeli o se nang 'mala.

Sollubility: E qhibiliha ka har'a metsoako e mengata ea tlhaho e kang ethanol, ethers le hydrocarbons.

Boima: Boima ba eona bo ka bang 0.68 g/cm³.

Chefo: DMB ha e na chefo e nyane, empa ho pepeseha ho feteletseng ho ka baka ho teneha ha mahlo le ho hlohlona ha letlalo.

 

Sebelisa:

Motsoako oa lik'hemik'hale: DMB e atisa ho sebelisoa ho organic synthesis e le solvent, intermediate, kapa catalyst.

Indasteri ea peterole: DMB e boetse e sebelisoa e le k'hemik'hale ea bohlokoa ea ts'ebeliso ea jute petroleum refining le mekhoa ea petrochemical.

 

Mokhoa:

DMB e hlophisitsoe ka mokhoa o tloaelehileng ka alkylation ea methylbenzene le propylene. Mehato e tobileng e kenyelletsa ho itšoara ka methylbenzene le propylene mocheso o loketseng le khatello ka pel'a mokelikeli oa ho hlahisa DMB.

 

Lintlha tsa Tšireletseho:

Joalo ka sehlapolli sa lintho tse phelang, DMB ha e fetohe. Nakong ea tšebeliso, hoa hlokahala ho boloka moea o motle le ho qoba ho pepeseha ho feteletseng.

E ka baka ho teneha ha e kopana le letlalo le mahlo. Ho kopana nako e telele, ho hema, kapa ho koenya ho lokela ho qojoa.

Ha u boloka le ho sebetsana le DMB, ho lokela ho qojoa karabelo ea li-oxidants tse matla le li-acid tse matla.

Ha u kopana le ntho ena, hang-hang hlatsoa sebaka sa letlalo kapa mahlo a silafetseng ka metsi a mangata 'me u batle ngaka.
