Hoʻolauna

ʻO 3,4-Hexanedione (ʻike pū ʻia ʻo 4-Hexanediic Acid) kahi mea hoʻohui. He hoʻolauna pōkole kēia i kāna mau waiwai, hoʻohana, hana hana, a me ka ʻike palekana.

 

ʻAno maikaʻi:

- Ke ʻano: 3,4-Hexanedione kahi paʻa kala kala ʻole.

- Solubility: Hiki ke hoʻoheheʻe ʻia e like me ka wai, nā waiʻona a me nā ethers.

- Nā waiwai kemika: ʻO 3,4-hexanedione kahi hui ketone me ka hana ketone maʻamau. Hiki ke hoʻemi ʻia i ka diol a i ʻole hydroxyketone e pili ana, a hiki ke hana i nā hopena e like me ka esterification a me ka acylation.

 

E hoʻohana:

- Hiki ke hoʻohana ʻia ma ke ʻano he mea maka no ka uhi ʻana, plastics, a me ka rubber, a me ka mea waena no nā reagents kemika a me nā catalysts.

 

Hanana:

- Aia nā ʻano synthesis like ʻole o 3,4-hexanedione, ʻo kekahi o nā ʻano hoʻomākaukau maʻamau ʻo ka esterify formic acid a me propylene glycol e loaʻa ai ka ester o 3,4-hexanedione, a laila loaʻa ka huahana hope ma ka hydrolysis acid.

 

ʻIke palekana:

- ʻO 3,4-Hexanedione kahi hui kūlohelohe maʻamau a pono e pale ʻia mai ka hoʻopili ʻana me ka ʻili, inhalation a i ʻole ingestion.

- E ʻaʻahu i nā mea pale pilikino kūpono e like me nā mīkina lima, nā maka aniani, a me nā lole pale.

- I ka wā o ka mālama ʻana a me ka mālama ʻana, pono e nānā ʻia i nā kumu hoʻoheheʻe ʻia a pale ʻia ka pilina me nā mea puhi ahi, nā mea oxidants a me nā mea ʻē aʻe.
