Selelekela

4,5-Dimethylthiazole ke motsoako oa lintho tse phelang. Mona ke tse ling tsa thepa ea eona, ts'ebeliso, mekhoa ea tlhahiso, le tlhaiso-leseling ea polokeho:

 

Boleng:

- Ponahalo: Mokelikeli o se nang 'mala kapa o tiileng oa kristale.

- Solubility: E qhibiliha ka har'a lihlapolli tse ngata tsa tlhaho tse kang joala, ethers le ketone.

- Botsitso: E batla e tsitsitse mocheso oa kamore.

 

Sebelisa:

- E ka boela ea sebelisoa e le accelerator ea rabara le ntho e senyang rabara ho ntlafatsa thepa ea mochini ea rabara.

 

Mokhoa:

- 4,5-Dimethylthiazole e ka hlahisoa ke karabelo ea dimethyl sodium dithiolate le 2-bromoacetone.

- Rection equation: 2-bromoacetone + dimethyl dithiolate → 4,5-dimethylthiazole + sodium bromide.

 

Lintlha tsa Tšireletseho:

- 4,5-Dimethylthiazole ke motsoako oa lintho tse phelang 'me o lokela ho qojoa ka mehato e nepahetseng ea ho tšoara.

- Liatlana tse sireletsang, likhalase le moaparo oa hlokahala nakong ea ts'ebeliso.

- Qoba ho hema mouoane oa eona le ho netefatsa ts'ebetso sebakeng se nang le moea o motle.

- Haeba ho na le ho phatloha ka phoso mahlong, hlatsoa hang-hang ka metsi a mangata 'me u batle thuso ea bongaka hang-hang.

- Boloka 4,5-dimethylthiazole sebakeng se phodileng, se omileng hole le li-oxidants le li-acid tse matla.
