Hoʻolauna

He mea hoʻohui ʻia. ʻO C6H6BrFN kāna kumu hoʻohālike kemika a ʻo kona kaumaha molekala he 188.03g/mol.

 

ʻO ka hui he wai waihoʻoluʻu ʻole a ʻeleʻele melemele me kahi ʻala ʻala. Loaʻa iā ia kahi helu heheʻe o -2°C a me kahi helu hoʻolapalapa o 80-82°C. Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka ethanol a me ka dimethylformamide i ka mahana maʻamau.

 

Hiki ke hoʻohana ʻia ma ke ʻano he intermediate i ka organik synthesis a hoʻohana nui ʻia i ka ʻoihana pesticide, lāʻau lapaʻau a me nā ʻepekema waiwai. Hiki ke hoʻohana ʻia no ka synthesis o nā pūhui acidic ʻē aʻe, glyphosate synthesis, microscopy a me ka lepili fluorescent, etc.

 

Hiki ke hoʻomākaukau ʻia ka phosphor ma ka hoʻokomo ʻana i ka bromine a me ka fluorine i loko o ka picoline. ʻO kahi ala maʻamau ka hoʻohana ʻana i ka bromine a me ke kinoea fluorine e hana me 2-methylpyridine. Pono e hoʻokō ʻia ka hopena i loko o kahi mea hoʻoheheʻe kūpono a pono e hoʻomehana a hoʻoulu.

 

E pili ana i ka ʻike palekana, e mālama i ke ahi a me ka wela kiʻekiʻe. E hoʻohana me nā mīkina lima pale kūpono a me ka pale maka. Inā pili i ka ʻili a i ʻole nā ​​maka, holoi koke me ka wai nui a ʻimi i ke kōkua olakino. Pono e mālama ʻia nā lula palekana kemika i ka wā o ka mālama ʻana a me ka mālama ʻana.
