Hoʻolauna

He mea hoʻohui ʻia. ʻO C8H5NO2 kāna kumu mole, ʻo HO-C6H3(CN)2 ke kumu hoʻohālike.

 

he paʻa waihoʻoluʻu ʻole me ka ʻala phenol. He kiʻekiʻe ka heheʻe a me ka paila paila, hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me nā ethers, nā ʻona a me nā ketones, hiki ʻole ke hoʻoheheʻe ʻia i ka wai.

 

ʻO ka hoʻohana nui ʻana o kēia pūhui he mea koʻikoʻi i waena o ka synthesis organik. Hiki ke hoʻohana ʻia i ka synthesis o nā polyesters novel no ka hoʻomākaukau ʻana i nā pūhui optical, uila a me nā lāʻau lapaʻau. Eia kekahi, hiki ke hoʻohana ʻia ma ke ʻano he mea maka no nā mea hoʻopili hana a me nā uhi.

 

ʻOi aku ka paʻakikī o ke ʻano hoʻomākaukau o ka hana. ʻO kekahi o nā kumu nui ka hopena o ka p-phenolate sulfate me ka sodium cyanide ma lalo o nā kūlana alkaline e hana ai i ka 4-hydroxy-2-phenylbenzonitrile, a laila loaʻa i ka decarboxylation acid-catalyzed.

 

I ka hoʻohana ʻana a me ka lawelawe ʻana, pono ʻoe e makaʻala i nā mea palekana. Loaʻa iā ia kahi hoʻonāukiuki, pale i ka ʻili a me ka inhalation. Pono e hoʻohana ʻia nā mea pale kūpono, e like me nā mīkina lima lab a me nā mea pale hanu i ka wā o ka hana. Eia kekahi, pono e pale ʻia ka launa pū ʻana me nā mea oxidizing a me nā ʻakika ikaika e pale aku i nā hopena pōʻino. I ka wā o ka mālama ʻana, e hoʻokaʻawale i ke ahi a me nā kumu wela, a hoʻopaʻa ʻia ka ipu i mea e pale ai i ka volatilization a me ka leakage.
