Ka Hoʻomākaʻikaʻi ʻana o ka Lae paila o Triethylamine
ʻO Triethylamine (TEA no ka pōkole) he pūhui kūlohelohe maʻamau i pili i ka papa amine o nā kinikona. Hoʻohana nui ʻia ia i nā ʻoihana he nui e like me nā lāʻau lapaʻau, pesticides, dyes, solvents a pēlā aku. Ma ke ʻano he mea hoʻohana maʻamau, ʻo nā waiwai kino o Triethylamine, ʻoi aku ka nui o kona wahi hoʻolapalapa, he mau ʻāpana e pono e hoʻomaopopo pono ʻia a mālama ʻia i nā kaʻina hana kemika. Ma keia pepa, e kukakuka kakou i ka lae paila o ka triethylamine me ka kiko'ī, e kālailai i nā kumu physicochemical ma hope o ia mea, a me kona koʻikoʻi i nā hana pono.
ʻO ka nānā ʻana o ka pae paila o triethylamine
ʻO 89.5°C (193.1°F) ka helu hoʻolapalapa o ka triethylamine, ʻo ia kona wela e hoʻolapalapa ai ma ke kaomi lewa maʻamau (1 atm). ʻO ka helu hoʻolapalapa ʻo ia ka mahana e like ai ke kaomi mahu o ka wai me ke kaomi o waho, ʻo ia hoʻi, ma kēia mahana e hoʻololi ʻia ka triethylamine mai kahi ʻano wai a i kahi kūlana kinoea. He waiwai kino ko'iko'i ka helu paila o kekahi mea a he mea nui ia no ka hoomaopopo ana i ka hana o ka triethylamine ma lalo o na ano like ole.
Nā mea e pili ana i ka helu hoʻolapalapa o triethylamine
Hoʻopili nui ʻia ka wahi paila o ka triethylamine e kona ʻano molecular a me nā ikaika intermolecular. ʻO Triethylamine kahi amine tertiary nona ka molecular structure i loko o ka nitrogen atom i hoʻopili ʻia i ʻekolu hui ethyl. No ka mea, hoʻokahi wale nō pālua o nā electrons ma ka atom nitrogen i loko o ka mole triethylamine, ʻaʻole maʻalahi i ka triethylamine ke hana i nā paʻa hydrogen. Hoʻolilo kēia i nā ikaika intermolecular o triethylamine ka nui o nā pūʻali van der Waals, he ʻano nāwaliwali. ʻO ka hopena, he haʻahaʻa loa ka pae paila o triethylamine.
ʻO nā kaulahao hydrocarbon i loko o ka mole triethylamine he ʻano hydrophobic, a he hopena hoʻi i kona wahi paila. ʻO Triethylamine kahi paona molekala haʻahaʻa i hoʻohālikelike ʻia me nā amine organik like ʻole, e wehewehe hapa ana i kona wahi paila haʻahaʻa. ʻO ka hui pū ʻana o ka molecular structure a me intermolecular forces o triethylamine e hoʻoholo i kona wahi paila o 89.5°C. ʻO ka paila paila o ka triethylamine kekahi hana o ka molecular structure o ka amine.
ʻO ke koʻikoʻi o ka paila paila o triethylamine i nā noi ʻoihana
He mea nui e hoʻomaopopo a hoʻopaʻa i ka wahi paila o ka triethylamine i ke kaʻina hana kemika. No ka mea kokoke i ka 90 ° C ka paila paila o ka triethylamine, hiki ke hoʻokō ʻia ka hoʻokaʻawale maikaʻi a me ka hoʻomaʻemaʻe ʻana o ka triethylamine ma ka hoʻoponopono ʻana i ka mahana i ka wā o ka hopena a me ke kaʻina kaʻawale. No ka laʻana, i ka wā distillation, hiki ke hoʻokaʻawale maikaʻi iā ia mai nā pūhui ʻē aʻe me nā wahi paila like ʻole. He mea koʻikoʻi hoʻi ka ʻike ʻana i ke kumu hoʻolapalapa o ka triethylamine no ka hana palekana e pale aku ai i nā poho volatile pono ʻole a i ʻole nā ​​​​pilikia palekana ma muli o nā wela keu.
Ka hopena
He 89.5°C ka helu hoʻolapalapa o Triethylamine. Hoʻoholo ʻia kēia waiwai kino e kona ʻano molecular a me nā ikaika intermolecular. I loko o ka ʻoihana kemika, he mea koʻikoʻi ka mana pololei o ka paila paila o triethylamine no ka huahana a me ka palekana. ʻO ka hoʻomaopopo ʻana i ka pae paila o ka triethylamine ʻaʻole kōkua wale i ka hoʻomaikaʻi ʻana i ke kaʻina hana, akā hāʻawi pū kekahi i ke alakaʻi koʻikoʻi i nā hana kūpono.
