Hoʻolauna
ʻO 2-Chloro-4′-fluoroacetophenone kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:
ʻAno maikaʻi:
- Ke ʻano: 2-Chloro-4′-fluoroacetophenone he wai kala ʻole a ʻeleʻele melemele.
- Solubility: Hiki ke hoʻoheheʻe ʻia e like me ka chloroform, ethanol a me ka ether.
E hoʻohana:
- Ka noiʻi kemika: ʻO 2-chloro-4′-fluoroacetophenone ka mea maʻamau i hoʻohana ʻia ma waena o ka synthesis organik a hiki ke hoʻohana ʻia i ka synthesis o nā mea hoʻohui ʻē aʻe.
Hanana:
- Nui nā ʻano hoʻomākaukau no ka 2-chloro-4′-fluoroacetophenone, a loaʻa kekahi o nā ʻano hana maʻamau e ka fluorination o chloroacetophenone. ʻO nā ʻanuʻu kikoʻī e pili ana i ka hoʻohui ʻana i ka waika hydrofluoric a me ka sodium palladium hydroxide catalyst i ka solvent reaction e hana i ka chloroacetophenone me ke kinoea fluorine e hana i ka 2-chloro-4′-fluoroacetophenone.
ʻIke palekana:
- ʻO ka 2-Chloro-4′-fluoroacetophenone he mea hoʻohuihui mea ola, a ʻo kona mau mea ʻino e pono ke mālama pono.
- I ka hoʻohana ʻana a mālama ʻana paha, e pale i ka hoʻopili ʻana me nā mea hiki ke hoʻopau ʻia, nā mea hoʻoneʻe ikaika, a me nā waikawa ikaika.
- Pono e lawe ʻia ka ventila kūpono i ka wā o ka hana ʻana a pono e hoʻohana ʻia nā lako pale pilikino kūpono e like me nā mīkina lima a me nā maka aniani palekana.
