Hoʻolauna

ʻO 2,3-dimethyl-2-butene (DMB) kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, hana hana a me ka ʻike palekana:

 

ʻAno maikaʻi:

ʻAno: He wai kala ʻole ka DMB.

Solubility: Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol, ethers, a me nā hydrocarbons.

Density: ʻO kona mānoanoa ma kahi o 0.68 g/cm³.

ʻAiʻona: ʻAʻole ʻona ka DMB, akā hiki i ka hoʻolaha nui ʻana ke hoʻonāukiuki i ka maka a me ka ʻili.

 

E hoʻohana:

Hoʻohui kemika: Hoʻohana mau ʻia ka DMB i ka synthesis organik ma ke ʻano he solvent, intermediate, a i ʻole catalyst.

ʻOihana ʻaila: Hoʻohana ʻia ʻo DMB ma ke ʻano he mea hoʻohana waiwai nui i ka jute petroleum refining a me nā kaʻina petrochemical.

 

Hanana:

Hoʻomākaukau maʻamau ka DMB e ka alkylation o methylbenzene a me propylene. ʻO nā ʻanuʻu kikoʻī e pili ana i ka hana ʻana i ka methylbenzene a me ka propylene i ka mahana kūpono a me ke kaomi ma ke alo o kahi mea hoʻoheheʻe e hoʻohua i ka DMB.

 

ʻIke palekana:

Ma ke ʻano he mea hoʻoheheʻe organik, hiki ke hoʻololi ʻia ka DMB. I ka wā o ka hoʻohana ʻana, pono ia e mālama i ka ventila maikaʻi a pale i ka hoʻolaha nui.

Hiki ke hoʻonāukiuki ke pili me ka ʻili a me nā maka. Pono e pale i ka pili lōʻihi, inhalation, a i ʻole ka ʻai ʻana.

I ka mālama ʻana a me ka mālama ʻana i ka DMB, pono e pale ʻia nā hopena me nā oxidants ikaika a me nā waikawa ikaika.

Inā pili me kēia mea, holoi koke i ka ʻili i haumia a i ʻole nā ​​maka me ka wai nui a ʻimi i ka lāʻau lapaʻau.
