Hoʻolauna

ʻO ka P-cresol acetate, ka mea i kapa ʻia ʻo ethoxybenzoate, he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka acetic acid p-cresol ester:

 

ʻAno maikaʻi:

ʻO ka p-cresol acetate he wai kala ʻole me ka ʻala ʻala. Hiki ke hoʻoheheʻe ʻia ka pūhui i loko o nā mea hoʻoheheʻe organik e like me ka ethanol a me nā ethers, akā kakaʻikahi i ka wai.

 

E hoʻohana:

Loaʻa i ka p-cresol acetate nā ʻano hoʻohana i ka ʻoihana. He mea hoʻoheheʻe ʻenehana maʻamau i hiki ke hoʻohana ʻia i nā uhi, nā mea hoʻopili, nā resins, a me nā mea hoʻomaʻemaʻe. Hiki ke hoʻohana ʻia ma ke ʻano he fixative no nā ʻala a me nā musks, e ʻae ana i nā ʻono a me nā mea ʻala e lōʻihi.

 

Hanana:

Hiki ke hoʻomākaukau ʻia ka p-cresol acetate e ka transesterification. ʻO ke ala maʻamau, ʻo ia ka wela a me ka hana ʻana i ka p-cresol me ka acetic anhydride i mua o kahi mea hoʻoheheʻe waika e hana i ka p-cresol acetate a me ka acetic acid.

 

ʻIke palekana:

He mea ʻawaʻawa a hoʻonāukiuki i ka cresol ester. I ka hoʻohana ʻana a i ʻole ka hana ʻana, pono e mālama pono i ka pale ʻana i ka ʻili a me nā maka a pale i ka hoʻopili pololei ʻana. Inā komo a inhaled, e ʻimi koke i ka lāʻau lapaʻau. Pono e mālama ʻia ma kahi ʻoluʻolu, ventilated a maloʻo, mamao mai ke ahi a me nā oxidizers, e hōʻoia i ka hoʻohana palekana.
