Hoʻolauna

ʻO Cresol, i kapa ʻia ʻo methylphenol (inoa Pelekane ʻo Cresol), he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka p-toluenol:

 

ʻAno maikaʻi:

ʻAno: He wai kala ʻole a melemele paha ʻo Cresol me kahi ʻala phenolic kūikawā.

Solubility: Hiki ke hoʻoheheʻe ʻia i loko o nā ʻawaʻawa, nā etera a me nā etera, a hiki ke hoʻoheheʻe iki ʻia i ka wai.

Nā waiwai kemika: He mea ʻakika ka Cresol e hoʻopili me ka alkali e hana i ka paʻakai pili.

 

E hoʻohana:

Hoʻohana ʻenehana: Hoʻohana ʻia ʻo Cresol ma ke ʻano he preservative, disinfectant, a me ka solvent i ka hana ʻana i nā preservatives. Hoʻohana pū ia ma ke ʻano he catalyst a me ka solvent i loko o nā ʻoihana lāʻau a me ka resin.

Hoʻohana mahiʻai: Hiki ke hoʻohana ʻia ka Toluene i ka ʻoihana mahiʻai ma ke ʻano he insecticide a me ka fungicide.

 

Hanana:

Nui nā ala e hoʻomākaukau ai i ka toluenol, hoʻohana maʻamau ʻia kekahi o ia mea e loaʻa ai ia ma o ka hopena oxidation o toluene. ʻO ka ʻanuʻu kikoʻī e hana mua i ka toluene me ka oxygen e hana ai i toluol ma lalo o ka hana a kahi catalyst.

 

ʻIke palekana:

He mea ʻawaʻawa ʻo Cresol, a ʻo ka hoʻopili pololei ʻana a i ʻole ka inhalation o ka nui o ka cresol hiki ke hōʻeha i ke olakino. Pono e hahai ʻia nā kaʻina hana palekana pili i ka wā e hoʻohana ʻia ai, a pono e hoʻohana ʻia nā mea pale kūpono.

Hōʻalo i ka pili lōʻihi me ka ʻili a pale i ka hoʻohu ʻana i kona mahu.

I ka mālama ʻana a me ka mālama ʻana i ka toluenol, pono e hoʻopaʻa pono ʻia a mālama ʻia mai ka ʻā a me nā wela kiʻekiʻe.
