Hoʻolauna

ʻO 3,4-Xylenol, i kapa ʻia ʻo m-xylenol, he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 3,4-xylenol:

 

ʻAno maikaʻi:

- 3,4-Xylenol he wai kala ʻole me kahi ʻala ʻala kūikawā.

- Loaʻa iā ia ka waiwai o ka hoʻoheheʻe ʻia i ka wai a me nā mea hoʻoheheʻe organik he nui.

- Hōʻike ʻia ma ke ʻano he ʻano dimer transverse ma ka wela lumi.

 

E hoʻohana:

- Hoʻohana ʻia ia ma ke ʻano he antibacterial a me antiseptic i loko o nā fungicides a me nā preservatives.

- Hoʻohana ʻia ma ke ʻano he catalyst i kekahi mau hopena synthesis kemika.

 

Hanana:

- Hiki ke hoʻomākaukau ʻia ka 3,4-Xylenol e ka hopena condensation o ka phenol a me ka formaldehyde ma lalo o nā kūlana acidic.

- I ka hopena, hoʻopili ʻia ka phenol a me ka formaldehyde e kahi mea hoʻoheheʻe ʻakika e hana i ka 3,4-xylenol.

 

ʻIke palekana:

- ʻO 3,4-Xylenol ka haʻahaʻa haʻahaʻa, akā he mea nui ia e hoʻohana me ka palekana.

- Hiki i nā mahu a i ʻole nā ​​pulupulu ke hoʻonāukiuki a ʻino i ka maka a me ka ʻili.

- I ka hana ʻana, e hoʻohana i nā lako pale pilikino kūpono, e like me nā mīkina lima kemika a me nā maka aniani.

- I ka mālama ʻana a me ka mālama ʻana i ka 3,4-xylenol, he mea nui e hoʻokele pono i ka ʻōpala e pale aku ai i ka haumia o ke kaiapuni.
