Hoʻolauna

ʻO Furoyl acetate, ka mea maʻamau i kapa ʻia ʻo acetylsalicylate, he mea hoʻohuihui. ʻO ka mea aʻe kahi hoʻolauna i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka furfuryl acetate:

 

ʻAno maikaʻi:

ʻO Furfuryl acetate kahi wai ʻole i ka ʻeleʻele melemele me kahi ʻala kūikawā. Hiki ke hoʻoheheʻe ʻia i loko o nā ʻano mea hoʻoheheʻe organik, e like me nā ʻona a me nā ethers, ma ka lumi wela.

 

Hoʻohana: He ʻono hua ʻala a hoʻohana pinepine ʻia i nā mea ʻala a me nā mea ʻala e hoʻonui ai i ka ʻala a me ka ʻono o ka huahana. Hiki ke hoʻohana ʻia ʻo Furfur acetate i nā noi ʻoihana e like me nā uhi, plastics a me ka lāʻau.

 

Hanana:

Hoʻomākaukau ʻia ʻo Furfur acetate e ka esterification reaction, ʻo ka hana kikoʻī e hana i ka furfuric acid me ka acetic anhydride, e hoʻohui i nā catalysts esterification e like me ka sulfuric acid a i ʻole ammonium formate, a hana i kahi mahana a me ka manawa. I ka pau ʻana o ka hopena, hoʻoneʻe ʻia nā haumia e ka dehydration a me ka distillation e loaʻa ai ka furfuryl acetate maʻemaʻe.

 

ʻIke palekana:

ʻO ka Furfuryl acetate he haʻahaʻa haʻahaʻa, akā hiki i ka inhalation lōʻihi ke loaʻa i nā hopena olakino. ʻO ka Furfur acetate kahi wai wela a pono e mālama ʻia mai nā lapalapa ākea a me nā kumu wela kiʻekiʻe, a mālama ʻia i kahi anuanu a me ka makani. E noʻonoʻo i nā hana pale i ka wā e hoʻohana ai, e like me ke komo ʻana i nā aniani pale, nā mīkina lima pale a me nā lole pale. Inā he wai a make paha, e hana koke i nā hana kōkua mua a e ʻimi i ka lāʻau lapaʻau i ka manawa.
