ʻO Scandium trifluoromethanesulfonate, i kapa ʻia ʻo Scandium(III) triflate, he hui kemika me ke ʻano Sc(SO3CF3)3, he paʻakai i loaʻa nā scandium cations Sc3 + a me triflate SO3CF3?anions.
ʻO Scandium (III) triflate he mea hoʻoikaika ikaika, kūpono, hiki ke hoʻihoʻi a hoʻohana hou ʻia acylation catalyst.He mea hoʻoikaika koʻikoʻi ia no ka Friedel-Crafts acylation, Diels-Alder reactions a me nā hopena hoʻopaʻa kalapona kalapona ʻē aʻe.Hoʻopiʻi stereochemically ia i ka polymerization radical o nā acrylates.Scandium(III) triflate complex o (4′S,5′S)-2,6-bis[4′-(triisopropylsilyl)oxymethyl-5′-phenyl-1′,3′-oxazolin-2′-yl] pyridine ua hoʻohana ʻia ma ke ʻano he catalyst no ka hopena Friedel-Crafts asymmetric ma waena o nā indoles i pani ʻia a me ka methyl (E) -2-oxo-4-aryl-3-butenoates.

Hoʻohana nui ʻia ʻo Scandium (III) trifluoromethanesulfonate ma ke ʻano he catalyst i ka hydrothiolation, koho ʻelua-electron hōʻemi o ka oxygen e nā ferrocene derivatives a me vinylogous Fridel-crafts alkylation o indoles a me pyrrole i ka wai.Ua komo i loko o ka Mukaiyama aldol hoʻohui a stereochemically catalyzes ka radical polymerization o acrylates.Hana ʻo ia ma ke ʻano he mea hoʻohuihui Lewis a hoʻohana ʻia i ka synthesis o ka bullvalone ma o ka sulfur ylide paʻa.
ʻO ka lawelawe hiki iā mākou ke hāʻawi
1) Hiki ke hoʻopaʻa inoa ʻia ka ʻaelike maʻamau
2) Hiki ke pūlima ʻia ka ʻaelike hūnā
3) ʻEhiku lā hoʻihoʻi hōʻoia
ʻOi aku ka mea nui: hiki iā mākou ke hāʻawi i ka huahana wale nō, akā ʻo ka lawelawe ʻenehana hoʻonā!
He mea hana mākou, aia kā mākou hale hana ma Shandong, akā hiki iā mākou ke hāʻawi i kahi lawelawe kūʻai kūʻai hoʻokahi no ʻoe!

≤25kg: i loko o ʻekolu mau lā hana ma hope o ka loaʻa ʻana o ka uku.＞25kg: hoʻokahi pule
Loaʻa, hiki iā mākou ke hāʻawi i nā laʻana liʻiliʻi liʻiliʻi no ke kumu loiloi maikaʻi!
1kg no ka ʻeke fpr samples, 25kg a i ʻole 50kg no ka pahu, a i ʻole e like me kou makemake.
E mālama i ka pahu i paʻa paʻa i kahi maloʻo, anuanu a maikaʻi hoʻi.
