Hoʻolauna

ʻO Guaiacol kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o guaiacol luff:

 

ʻAno maikaʻi:

- Ke ʻano: ʻO Guaiac kahi wai aniani me kahi ʻala kūikawā.

- Solubility: Hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe, e like me ka ethanol a me ka ether.

 

E hoʻohana:

- Pesticides: Hoʻohana ʻia ʻo Guaiacol ma ke ʻano he mea hoʻohui i nā pesticides.

 

Hanana:

Hiki ke unuhi ʻia ka Guaiacol mai ka lāʻau guaiac (kahi mea kanu) a i ʻole synthesized e ka methylation o ka cresol a me ka catechol. ʻO nā ʻano hana synthesis ka hopena o ka p-cresol me ka chloromethane i hoʻopaʻa ʻia e ka alkali a i ʻole ka p-cresol a me ka waikawa formic ma lalo o ka catalysis acid a pēlā aku.

 

ʻIke palekana:

- He mea hoʻonāukiuki ka mahu a Guaiacol a loaʻa paha kahi hopena hoʻonāukiuki i ka maka, ka ʻili, a me ka ʻōnaehana hanu. E hoʻohana i nā maka maka pale, nā mīkina lima a me ka mask inā pono.

- Pono e mālama ʻia mai ke ahi a me nā wela kiʻekiʻe, a mālama ʻia i loko o kahi pahu ea e pale aku ai i ka hoʻopili ʻana me nā mea oxidants.

- I ka hoʻohana ʻana i ka guaiacol i loko o kahi kaiapuni maikaʻi a pale i ka hoʻohu ʻana i kona mau mahu no ka manawa lōʻihi.

- E mālama pono i ka hui e like me nā kaʻina hana kūpono a me nā alakaʻi alakaʻi palekana. Inā pili me ka ʻili a hoʻohana paha, holoi koke me ka wai nui a ʻimi i ke kōkua olakino.
