Okwu mmalite

2-Methylthiothanol, nke a makwaara dị ka 2-methylthioethanol, bụ ngwakọta organic. Ndị a bụ mmalite nke akụrụngwa ya, ojiji ya, ụzọ nrụpụta ya na ozi nchekwa:

 

Ogo:

- Ọdịdị: 2-Methylthioethanol bụ mmiri na-acha odo odo na-enweghị agba.

- Odor: nwere isi ike nke hydrogen sulfide.

- Solubility: Soluble na mmiri na ụfọdụ ihe mgbaze organic dị ka alcohols na ethers.

- Njirimara: Ọ na-enwe mmetụta nke ikuku ma nwee ike oxidized ka disulfide, nke dị mfe ime ka ọkụ.

 

Jiri:

- Ngwakọta kemịkalụ: 2-methylthiothanol nwere ike iji dị ka etiti na njikọ organic.

- Detergent: Enwere ike iji ya dị ka ihe mkpuchi na ncha na nkwadebe nke ihe ncha.

- Mgbochi ire ọkụ na-aba n'anya: 2-methylthioethanol nwere ike iji mee ihe dị ka ihe na-egbochi ọkụ mmanya.

 

Usoro:

2-Methylthioethanol nwere ike kwadebere site na:

- Thiothanol na-etolite site na mmeghachi omume na methyl chloride.

- Ethiohydrazine na-etolite site na mmeghachi omume na ethanol.

 

Ozi nchekwa:

- 2-Methylthiothanol nwere isi na-esi ísì ụtọ ma nwee ike ịkpasu anya na mgbakasị anụ ahụ mgbe emetụrụ ya aka.

- Mgbe ikuru ume, ọ nwere ike ịkpata mgbakasị iku ume na ahụ erughị ala n'obi.

- Iri ma ọ bụ iri nnukwu ego nwere ike ịkpata nsị, na-ebute mgbakasị afọ.

- Yiri akụrụngwa nchebe kwesịrị ekwesị dị ka uwe aka na ugo nchekwa mgbe ị na-eji.

- Mgbe ị na-arụ ọrụ, zere ọkụ na-emeghe na ebe okpomọkụ dị elu iji zere ịkpalite combustion.
