Hoʻolauna
ʻO FEMA 2899(Isobutyl 3-phenylpropionate) he mea hoʻohuihui mea ola me ke ʻano kemika C13H18O2. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.
ʻAno:
He wai kala ʻole ʻo FEMA 2899 me kahi ʻala ʻala. He haʻahaʻa haʻahaʻa ke kaomi mahu a me ka solubility, a ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai.
E hoʻohana:
Hoʻohana mau ʻia ʻo FEMA 2899 ma ke ʻano he waena kemika, kahi hui e hana ma ke ʻano he pilina a hoʻololi paha i ke kaʻina hana synthesis. Hoʻohana pinepineʻia i ka hoʻomākaukauʻana i nā meaʻala a me nā meaʻala, e hoʻonui i kaʻono a iʻole e hoʻololi i kaʻono. Eia kekahi, hiki ke hoʻohana ʻia e like me ka solvent no nā hopena synthesis organik.
Kaʻina hoʻomākaukau:
Hoʻomākaukau ʻia ʻo FEMA 2899 e ka hopena esterification ma waena o isobutanol a me 3-phenylpropionic acid. I ka hopena, ua hoʻohui ʻia ka isobutanol a me ka 3-phenylpropionic acid i kahi moku pane i kahi ratio kūpono, hoʻohui ʻia kahi catalyst e like me ka sulfuric acid a hoʻomehana ʻia, a ʻohi ʻia ka huahana FEMA 2899.
ʻIke palekana:
ʻAʻohe pōʻino maopopo o ka FEMA 2899 i ke kino kanaka a me ke kaiapuni ma lalo o nā kūlana hoʻohana maʻamau. Eia nō naʻe, ma ke ʻano he kemika, pono nō e hoʻolohe i ka palekana ke hoʻohana ʻia. Manaʻo ʻia e ʻaʻahu i nā mea pale kūpono e like me nā mīkina lima, nā maka aniani a me nā lole pale i ka wā o ka hana e pale aku ai i ka pili ʻana me ka ʻili a me nā maka. Pono e mālama ʻia e pale aku i ka hoʻopili ʻana me nā oxidants, nā ʻakika ikaika, nā kumu ikaika a me nā mea ʻē aʻe e pale aku ai i nā hopena pōʻino. I nā hihia a pau, pono e hahai i nā kaʻina hana kūpono a me nā ʻōlelo paipai no ka hoʻohana palekana. Ina he leaka a ulia paha, e laweia na hana kupono. No ka ʻike pono palekana a me nā ʻōlelo aʻoaʻo hana, pono e hana ʻia i nā pepa ʻikepili palekana kūpono a me nā kuhikuhi no ka hoʻohana ʻana.
