2-(chloromethyl)-5-(trifluoromethyl)-1 3 4-oxadiazole（CAS# 723286-98-4)
Hoʻolauna
ʻO 2-(chloromethyl) -5- (trifluoromethyl) -1,3,4-oxadiazole kahi mea hoʻohuihui me ke ʻano C4H2ClF3N2O.
ʻAno:
2-(chloromethyl)-5-(trifluoromethyl)-1,3,4-oxadiazole he wai kala ʻole i ka ʻeleʻele melemele a i ʻole crystalline paʻa. Loaʻa iā ia ke kūpaʻa wela kiʻekiʻe a me ka inertness kemika. ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai ma ka lumi wela, hiki ke hoʻoheheʻe ʻia i loko o kekahi mau mea hoʻoheheʻe kūlohelohe e like me ka ethanol a me ka etera. Hiki ke ʻike ʻia ka pūhui e nā ʻenehana e like me ka nuclear magnetic resonance a me ka spectrometry nuipa.
E hoʻohana:
2-(chloromethyl) -5-(trifluoromethyl) -1,3,4-oxadiazole i kekahi waiwai noi ma ke kahua o ka kemika. Hoʻohana pinepine ʻia ʻo ia ma ke ʻano he waena i ka synthesis organik no ka synthesis o nā pūhui ʻē aʻe. Eia kekahi, hoʻohana ʻia ia ma ke ʻano he reagent noiʻi ma ke kahua o nā pesticides a me nā lāʻau lapaʻau.
Kaʻina hoʻomākaukau:
2-(chloromethyl) -5- (trifluoromethyl) -1,3,4-oxadiazole hiki ke synthesized e nā ʻano hana like ʻole. Eia ke ʻano hoʻomākaukau maʻamau.
1. E hoʻohui i kahi catalyst (e like me ka triethylamine) i kahi ʻōnaehana hoʻoheheʻe organik anhydrous.
2. E hoʻohui i kahi nui o ka methyl 3-chloropropionate a me ka methyl trifluoroformate i ka ʻōnaehana solvent.
3. Hoʻokō ʻia ka hopena ma kahi mahana kūpono ma lalo o kahi ea inert, a he mea maʻamau ka pono e wela i ka hui ʻana.
4. ʻO ka kānana a i ʻole ka distillation e loaʻa ai ka huahana, ma hope o ka hoʻomaʻemaʻe kūpono a me ka hoʻomaloʻo ʻana e loaʻa ai ka huahana maʻemaʻe.
ʻIke palekana:
2-(chloromethyl)-5-(trifluoromethyl)-1,3,4-oxadiazole maʻamau ka palekana ke hoʻohana ʻia a mālama pono ʻia. Eia nō naʻe, ma ke ʻano he pūhui organik, hiki ke hoʻopilikia i ke olakino kanaka a me ke kaiapuni. I ka hoʻohana ʻana a me ka lawelawe ʻana, pono e hahai i nā kaʻina hana palekana kūpono, a pale i ka pili pololei. Pono e heluhelu pono ʻia nā ʻōlelo aʻoaʻo palekana e pili ana i ka hui. Inā pono, pono e hana ʻia ka hana ma lalo o ke alakaʻi ʻana o nā limahana limahana.
