Hoʻolauna

ʻO 2-pentathiol, i ʻike ʻia he hexanethiol, he hui organosulfur. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:

 

ʻAno maikaʻi:

- Ke ʻano: ʻO ka wai kala ʻole me kahi ʻala ʻokoʻa.

- Paʻa: Paʻa ma lalo o nā kūlana maʻamau, akā hiki ke hoʻopili ʻia e ka oxygen, acid, a me ka alkali.

 

E hoʻohana:

- Hoʻohana ʻoihana: 2-pentylmercaptan hiki ke hoʻohana ʻia ma ke ʻano he mea maka no nā mea vulcanizing agents, anti-aging agents, lubricants and rust inhibitors.

 

Hanana:

- Ma ka hana ʻoihana, hoʻomākaukau nui ʻia ka 2-pentyl mercaptan e ka hopena o ka hexane a me ka sulfur i mua o kahi catalyst.

- I loko o ka hale hana, hiki ke hoʻomākaukau ʻia ka 2-pentyl mercaptan e ka dehydrogenation ma hope o ka hopena hexane me ka hydrogen sulfide.

 

ʻIke palekana:

- 2-Penylmercaptan he mea hoʻonāukiuki a hoʻomāinoino, e hoʻoulu ai i ka huhū a me ke ahi e pili ana i kaʻili a me nā maka.

- Hiki ke hōʻeha i ke poʻo, ʻūlū a me ka nausea ke hoʻohu ʻia.

- Inā ale ʻia, hiki ke make.

- I ka hoʻohana ʻana a me ka mālama ʻana, pono e mālama ʻia e pale aku i ka hoʻopili ʻana me ka oxygen, nā waikawa, a me nā alkalis e pale aku i nā hopena pōʻino.

- I ka wā e hoʻohana ai, pono ʻoe e ʻaʻahu i nā lako pale pilikino kūpono e like me nā mīkina lima, nā maka aniani, a me nā lole pale.

- Inā loaʻa ka pilikia a i ʻole ka inhalation, holoi koke i ka wahi i hoʻopilikia ʻia a ʻimi i ke kōkua olakino.
