Hoʻolauna
ʻO ka 2,5-difluorobenzoyl chloride he mea hoʻohuihui me ka ʻano kemika C7H3ClF2O, ʻo ia ka derivative o benzoyl chloride. He wai waihoʻoluʻu ʻole a ʻeleʻele melemele me ka ʻala ʻala. Eia ka wehewehe kikoʻī o ke ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana o 2,5-difluorobenzoyl chloride:
ʻAno:
-Ka mānoanoa: 1.448g/cm3
-Lae hehee:-21°C
-Ka Lae paila: 130-133°C
-Lahi uila: 46°C
-Solubility: Hiki ke hoʻoheheʻe ʻia e like me ka ether, chloroform, hiki ke hoʻoheheʻe ʻia i ka wai.
E hoʻohana:
- 2,5-difluorobenzoyl chloride he mea koʻikoʻi koʻikoʻi koʻikoʻi synthesis intermediate, hoʻohana mau ʻia i ka synthesis lāʻau a me ka synthesis pesticide.
-Hiki ke hoʻohana ʻia ma ke ʻano he reagent koʻikoʻi no ka synthesis o nā aldehydes aromatic.
- Hiki ke hoʻohana ʻia e synthesize i nā dyes, nā mea ʻala a me nā mea hoʻohui ʻē aʻe.
Kaʻina hoʻomākaukau:
Hoʻohui pinepine ʻia ka 2,5-difluorobenzoyl chloride e ke ʻano o ka chloride 2,5-difluorobenzoyl i loko o ka zinc a i ʻole 2,5-difluorobenzoyl i ka chloride sulfoxide. Hiki ke kuhikuhi ʻia nā ʻano hoʻomākaukau kūikawā i ka manual synthesis chemical synthesis a i ʻole palapala.
ʻIke palekana:
- 2,5-difluorobenzoyl chloride he mea hoʻopōʻino a pono e pale ʻia e ka inhalation, ingestion a me ka pili ʻana i ka ʻili.
-E hoʻohana i nā mea pale pilikino e like me nā mīkina lima pale kemika, nā maka aniani a me nā maka ke hoʻohana.
- Pono e hoʻohana ʻia ma kahi wahi e hoʻoheheʻe ʻia e pale aku i ka mahu a i ʻole ka uahi.
-I ka mālama ʻana a me ka mālama ʻana, e mālama i ka ʻā a me nā mea kūlohelohe, a pale i ka hoʻopili ʻana me nā oxidants.
-Ma hope o ka hoʻolei ʻana, e ʻoluʻolu e hoʻolei pono i ka ʻōpala a hahai i nā lula pili.
