Hoʻolauna

ʻO ka O-dibromobenzene kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka o-dibromobenzene:

 

ʻAno maikaʻi:

- Ke ʻano: ʻO-dibromobenzene kahi aniani kala ʻole a paʻa keʻokeʻo.

- Hoʻoheheʻe: Hiki ke hoʻoheheʻe ʻia ka O-dibromobenzene i kekahi mau mea hoʻoheheʻe kūlohelohe, e like me benzene a me ka waiʻona.

 

E hoʻohana:

- Nā mea uila uila: hiki ke hoʻohana ʻia ka o-dibromobenzene i ka hoʻomākaukau ʻana i nā mea optoelectronic organik, nā hōʻike aniani wai, etc.

 

Hanana:

Loaʻa ke ʻano hoʻomākaukau nui o ka o-dibromobenzene ma ka hoʻololi ʻana o ka bromobenzene. ʻO ke ʻano hana synthesis maʻamau ka hoʻoheheʻe ʻana i ka benzene i loko o ka hui ʻana o ka bromide ferrous a me ka dimethyl sulfoxide a hana i ka mahana kūpono e loaʻa ai ka o-dibromobenzene.

 

ʻIke palekana:

- Loaʻa i ka O-dibromobenzene kekahi mea ʻawaʻawa a pono e loiloi ʻia ka ʻikepili toxicity kikoʻī i kēlā me kēia hihia.

- E hoʻohana i nā mīkina lima a me nā maka aniani ke hoʻohana i ka o-dibromobenzene e pale i kou ʻili a me kou mau maka.

- Hōʻalo i ka hoʻohu ʻana i ka mahu o-dibromobenzene a i ʻole ka pipi ʻana ma ka maka a me ka ʻili.

- Hōʻalo i ka pilina ma waena o ka o-dibromobenzene a me nā oxidants ikaika, ʻā a me nā wela kiʻekiʻe.

- I ka wā o ka hoʻohana ʻana a me ka mālama ʻana, pono e uku ʻia ka nānā ʻana i nā hana pale ahi a pahū e mālama i ka ea maikaʻi.

- I ka wā e hoʻolei ai i ka ʻōpala, e mālama mākou i nā kānāwai kaiapuni a me nā lula a e hana i nā hana kūpono e hoʻolei i ka ʻōpala.
