Hoʻolauna
He pūhui mea ola ia me ke ʻano kemika C5H5ClN2. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.
ʻAno:
He wai waihoʻoluʻu a melemele me kahi ʻala kūikawā. He haʻahaʻa kona wahi paila a heheʻe ma ka lumi wela. Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me diethyl ether, acetone a me dichloromethane.
E hoʻohana:
He mea koʻikoʻi koʻikoʻi ia, hiki ke hoʻohana nui ʻia i ka synthesis o nā lāʻau lapaʻau a me nā pesticides. Hoʻohana ʻia ia ma ke ʻano he waena i ka synthesis o nā lāʻau like ʻole e like me nā lāʻau antiviral a me nā lāʻau antitumor. Eia hou, hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā pūhui organik ʻē aʻe, e like me nā dyes a me nā pūhui coordination.
Hanana:
Hiki ke kiʻi ʻia ke ʻano hoʻomākaukau o ka calcium ma ka hana ʻana i ka 2-methyl pyrimidine me ka thionyl chloride. Hiki ke hoʻololi ʻia nā kūlana hoʻohālikelike kikoʻī e like me nā koi hoʻokolohua, akā lawe ʻia nā kūlana maʻamau ma lalo o ka lewa inert, ka lumi lumi a i ʻole ka wela.
ʻIke palekana:
He haʻahaʻa kona ʻona ma lalo o nā kūlana hoʻohana maʻamau, akā pono mau nā hana pale kūpono. I ka wā o ka hana, pono e pale ʻia ka hoʻopili ʻana me ka ʻili, nā maka a me ka inhalation o nā mahu, a pono e hoʻohana i nā aniani pale a me nā mīkina lima inā pono. Inā pili ʻoe i kēia pūhui, holoi koke me ka wai nui a ʻimi i ke kōkua olakino. I ka manawa like, e pale i ka hui ʻana me nā oxidants ikaika a me nā waikawa ikaika e pale aku i ke ahi a i ʻole pahū. Pono e waiho ʻia ka waihona ma kahi maloʻo, ʻoluʻolu, maikaʻi-ventilated, mamao mai ke ahi a me nā mea puhi.
