Hoʻolauna

ʻO ka waiʻona Furfuryl. ʻO ka mea aʻe kahi hoʻolauna i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka furfuryl alcohol:

 

ʻAno maikaʻi:

ʻO ka waiʻona Furfuryl kahi wai ʻala ʻole me ka haʻahaʻa haʻahaʻa.

Hiki ke hoʻoheheʻe ʻia ka waiʻona Furfuryl i ka wai a hiki ke hui pū me nā mea hoʻoheheʻe organik.

 

E hoʻohana:

 

Hanana:

I kēia manawa, hoʻomākaukau nui ʻia ka furfuryl alcohol e ka synthesis kemika. ʻO kekahi o nā ʻano hana maʻamau ka hoʻohana ʻana i ka hydrogen a me ka furfural no ka hydrogenation i mua o kahi catalyst.

 

ʻIke palekana:

Manaʻo ʻia ka ʻona ʻo Furfuryl me ka palekana ma lalo o nā kūlana maʻamau o ka hoʻohana ʻana, akā hiki ke hoʻoulu i nā hopena maʻi i kekahi poʻe.

E hōʻalo i ka hoʻopili ʻana me ka waiʻona furfuryl ma nā maka, ka ʻili, a me nā membrane mucous, a holoi me ka wai nui inā loaʻa ka pili.

Pono ka ʻona ʻo Furfuryl e mālama pono i nā lima o nā keiki e pale aku i ka ʻai ʻana a i ʻole ka hoʻopā ʻana.
