Hoʻolauna

ʻO 2-Propantomercaptan, i ʻike ʻia ʻo propanol isosulfide, he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, hana hana a me ka ʻike palekana:

 

ʻAno maikaʻi:

- Ke ʻano: 2-He wai kala ʻole a melemele paha ka Propanol.

- Aala: He ʻala kūikawā e like me ke ʻala o ke kāleka.

- Solubility: Hiki ke hoʻoheheʻe ʻia i loko o ka wai a me nā mea hoʻoheheʻe he nui e like me ka ethanol a me ka ether.

- Paʻa: He hui paʻa ia, akā hiki ke hoʻoheheʻe ʻia i nā wela kiʻekiʻe a i ʻole nā ​​wahi oxygen kiʻekiʻe.

 

E hoʻohana:

- Nā hopena o ka Vulcanization: Loaʻa iā ia ka sulfur, a ua hoʻohana pinepine ʻia ka 2-propyl mercaptan e hoʻopale i nā hopena sulfidation.

 

Hanana:

- Hiki ke hoʻomākaukau ʻia ka 2-Propanthiol e nā ʻano hana like ʻole, loaʻa kahi ala maʻamau e ka hopena o ka propylene oxide a me ka sodium hydrosulfide.

 

ʻIke palekana:

- 2-He ʻala ʻala ko ka Propanol a hiki ke hoʻonāukiuki i ka maka, ka ʻili, a me ka ʻōpū hanu ke hoʻopili ʻia. E hoʻohana i nā mea pale kūpono, e like me nā mīkina lima, nā pale maka, a me nā maka aniani, e hōʻoia i ka maikaʻi o ka ea i ka wā e hoʻohana ai.

- Pono e mālama ʻia nā hana palekana i ka wā o ka mālama ʻana a me ka hoʻokuʻu ʻana e pale aku i ka hoʻopili ʻana a me ka hui ʻana me nā mea puhi. Pono e mālama ʻia i loko o kahi pahu hau, ma kahi mamao o ke ahi a me nā wela kiʻekiʻe.

- Ma mua o ka hoʻohana ʻana a me ka hoʻokuʻu ʻana, pono e heluhelu pono ʻia nā ʻōlelo aʻoaʻo palekana kūpono a me nā alakaʻi hana.
