ʻO 3-((2-mercapto-1-methylpropyl) sulfur) -2-butanol (ʻike nui ʻia ʻo mercaptobutanol) he mea hoʻohuihui.

 

He pilau ikaika ko Mercaptobutanol a he wai melemele māmā ke ʻano. Hiki ke hoʻoheheʻe maikaʻi ʻia a hiki ke hoʻoheheʻe ʻia i ka wai a me ka hapa nui o nā mea hoʻoheheʻe organik. He ʻakika nāwaliwali nō hoʻi.

 

Hoʻohana nui ʻia ʻo Mercaptobutanol i ke kahua o ka synthesis organik. Hiki ke hoʻohana ʻia ma ke ʻano he mea hōʻemi no nā pūhui e like me catechol, phenolphthalein, a me hypoamine. Hiki ke hoʻohana ʻia ʻo Mercaptobutanol ma ke ʻano he mea paʻakikī no ka nickel a me ka cobalt e hāpai i nā hopena oxygenation.

 

Hiki ke loaʻa ke ʻano hoʻomākaukau o mercaptobutanol ma ka hopena o mercaptoethylene me 1-chloro-2-methylpropane. Penei nā ʻanuʻu kikoʻī: mercaptoethylene i hana ʻia me 1-chloro-2-methylpropane ma lalo o nā kūlana alkaline e hana i ka mercaptobutanol. A laila, hoʻomaʻemaʻe ʻia e ka distillation a i ʻole nā ​​​​ʻanuʻu hoʻomaʻemaʻe ʻē aʻe.

He ʻala koʻikoʻi kona a pono e hoʻohana ʻia ma kahi wahi e hoʻoheheʻe ʻia. Hōʻalo i ka pili ʻana me ka ʻili a me nā maka. Inā komo a inhaled, e ʻimi koke i ka lāʻau lapaʻau.
