ʻO 3,4 '-Dichloropropiophenone, ʻano kemika C9H7Cl2O, he mea hoʻohuihui.

 

ʻAno:

3,4 '-Dichloropropiophenone he paʻa ʻole a ʻeleʻele melemele me kahi ʻala kemika ʻokoʻa. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai a hiki ke hoʻoheheʻe ʻia i loko o nā ʻona a me nā eter.

 

E hoʻohana:

Hoʻohana pinepine ʻia ʻo 3,4 '-Dichloropropiophenone ma ke ʻano he reagent i ka synthesis organik. Hiki ke hoʻohana ʻia i ka synthesis o nā lāʻau lapaʻau, nā kala a me nā mea ʻē aʻe. Hiki ke hoʻohana ʻia i mea maka no ka hoʻomākaukau ʻana i nā pesticides a me nā mea ʻono.

 

Kaʻina hoʻomākaukau:

Aia nā ʻano hana like ʻole no ka hoʻomākaukau ʻana i ka 3,4 '-Dichloropropiophenone. ʻO ke ala maʻamau ka loaʻa ʻana o 3,4′-dichlorophenyl etanone ma ka bromination a i ʻole chlorination ma lalo o nā kūlana alkaline.

 

ʻIke palekana:

ʻO 3,4 '-Dichloropropiophenone kahi mea ʻawaʻawa a pono e pale ʻia ka pili pono ʻana me ka ʻili a me ka inhalation o kona mau mahu. Pono e hoʻohana ʻia nā lako pale pilikino kūpono, e like me nā mīkina lima pale kemika a me ka pale maka, i ka wā e hoʻohana ai a lawelawe ʻia paha. E pale i ka wela wela a me ke ahi hāmama i ka wā mālama. Pono e hoʻohana ia mea ma kahi palekana a me ka makani a hoʻolei ʻia i loko o kahi pahu hoʻolei ʻole. Inā loaʻa ka ʻai ʻana a i ʻole ka pili ʻana, e ʻimi koke i ke kōkua olakino.
