Whakaahuatanga o ngā Mahi
Te āhua o te mokorā o BF3 he kowhiringa tuara. Ko tōna tohu D3h e whakaae ana i ngā whakaaturanga o te whakaata VSEPR. Kāore te mokorā i te momo dipole, nā tōna mohiotanga matua. Ko te mokorā nei he isoelectronic ki te anion karbonete, CO BF3 koia nei te mea e kīia ana ko "electron deficient", he whakaatu i tana hirahira i roto i ngā hoko whakapūmau a Lewis. I ngā mokorā torutoru fluorine, BX3, ko te rahi o ngā hononga B–X (1.30 Å) he iti rawa i te mea ka taea e pēnei i ngā hononga B–X π i te fluoride. He whakautu tino waiaro te whakamahinga i te kaweake p o te porihanga i runga i te atome boron me te porihanga katoa i te neke o ngā porihanga p tuatahi o te torutoru fluorine. Heoi anō, kei te kōrero ētahi nui ki te momo ionic o ngā hononga i roto i te BF3. Mō ngā hokinga rara hei wharepori, ko BF3 te mea e hangaia ana i te wā i roto i te āpure boron trifluoride, ko ia he wai riro i te ao komiti. He nuinga nui ngā ara wharepori ki ngā rauropi kore. Ko tētahi ara whakamārama e hāngai ana ki te whakawehenga wera o ngā pai maroke o BF. Ko te paetaha kuhu mai o te boron trifluoride korewai he -100.3 °C me te paetaha matua he -12.3 °C, nā reira ka taea e ia te noho hei waiware hānumi anake i waenganui i ēnei paetaha. Me hanga ngā wāhi whakamahere, ngā wāhi whakamahere, hei whakatika i te paetaha hānui, ina korerotia te hapa i te retini hānumi, ka puta te paetaha ki te paetaha matua he 49.85 bar (4.985 MPa). Ko te boron trifluoride he korosive. Ko ngā mete whakarite hei whakahaere i te boron trifluoride he tāwheiti, monel, me te hastelloy. Ki te noho mōhio, ka korosia ia i te tāwheiti, ā, he tāwheiti mōhio hoki. Ka hāpai ia i ngā polyamide. Ko ngā polytetrafluoroethylene, polychlorotrifluoroethylene, polyvinylidene fluoride, me te polypropylene e whiwhi ana i te mohiotanga pai. Ko te werewere e whakamahia i roto i te wharepori me whiwhi kē hei fluorocarbon, nā te mea ka hāpai te boron trifluoride i ngā werewere karawa.
AGEM e tuku ana i te rārangi whakahaere o te Boron Trifluoride ki te ao hiko, kei reira ā-matou ngā whiringa porihanga o te ao.
Ko te BoronTrifluoride (BF3) he waipū waewae e kore e taea te pūhuruhuru, ka whakamahia hei kātara rānei, ko te tuatahi kātara rānei mō ngā whakaritenga rite ā-tuauru, organic synthesis reactions. Ko ia tētahi o ngā Lewis acids haumaru (he whakaaetanga ā-poro) e mahi ana nui tonu i runga i ngā momo whenu e noho ana i roto i te oxygen, nitrogen, sulfur me ērā katoa e tuku poro mō te whakaaetanga.
Whakamahia ai te Boron Trifluoride hei kaihāpai mō ngā whakariterite organic, mō te hanga i ngā karatā teitei me ngā totohu
me i te hanga i ngā isotope boron hiwa i te waenganui.

FAQ
Pātai Tūmatawhiti 1. He aha te MOQ? W: Mai i tētahi puipui 2. He aha te wā tuku? W: 7-10 rā i muri i te hokohoko pūtea, I muri i te whakariterite o te mōkī ki waka moana rānei, ka mōhio mātau i te wā katoa hei tuku ki te whenua o te kaihoko. 3. Me pēhea te tiro i te pai o te hau? W: Tuatahi, ka mahi tō tāmatou rōpū i ngā puipui (he whakahoki, he whakatika, he whakawehi, he whakapuaki, me te whakawhiti i mua i te whakapae hau) kia pai ai te waewae i roto i te puipui. Tuarua, ka whakamātau tātou i ngā puipui anō, kia pai ai te waewae i roto i te puipui. Tuatoru, ka whakauru tātou i te hau ki ngā puipui me te tuku i te Rangahau Pūnaha (COA). 4.
