Folasaga
Sulfur trioxide-triethylamine lavelave (Sulfur trioxide-triethylamine complex) o se fa'aputuga sulfur fa'aola. O lona fua fa'atatau o le (C2H5)3N · SO3. O le lavelave e iai mea nei:
1. Faʻamautu faʻavae: O le lavelave e mausali i le vevela o le potu ma e lelei le mautu.
2. catalyst: o le lavelave e masani ona faʻaaogaina e avea o se faʻamalosi mo le acylation, esterification, amidation ma isi tali i le faʻaogaina o meaola.
3. Gaoioiga maualuga: Sulfur trioxide-triethylamine lavelave o se vaega sili ona malosi o le sulfate foaʻi, lea e mafai ona faʻamalosia lelei le tele o gaioiga i le faʻaogaina o meaola.
4. solvent o vai ionic: Sulfur trioxide-triethylamine lavelave e mafai ona faʻaaogaina e avea ma solvent o le vai ionic i nisi o gaioiga, e maua ai le siosiomaga catalytic lelei.
O auala sauniuni o le faʻalavelave e faʻapea:
1. Auala fa'afefiloi sa'o: fa'afefiloi sa'o le sulfur trioxide ma le triethylamine i se fua fa'atatau molar, fa'aoso ma tali i se vevela talafeagai, ma i'u ai ina maua Sulfur trioxide-triethylamine lavelave.
2. auala palapala: muamua sulfur trioxide ma triethylamine ua solo i se solvent talafeagai, o le solvent masani faaaogaina o carbon chloride po benzene. O lo'o i ai le lavelave i fofo i le tulaga o se vaega fofo ma e tu'ueseeseina ma fa'amamāina e ala i le fa'amauina.
E uiga i fa'amatalaga saogalemu:
1. Sulfur trioxide-triethylamine lavelave e pala ma ita i le pa'u ma mata. Fai totigilima puipui, matatioata ma lavalava e puipuia ai vailaau i le taimi o le taotoga.
2. E mafai e le fa'afefiloi ona gaosia kasa oona i le vevela maualuga. E tatau ona gauai atu i tulaga o le ea ma aloese mai le faʻafesoʻotaʻi ma mea faʻafefe.
3. I le taimi o le teuina ma le faʻaogaina, Sulfur trioxide-triethylamine complex e tatau ona vavae ese mai le vai, okesene ma isi vailaʻau e aloese ai mai faʻalavelave faʻalavelave.
A'o le'i faia so'o se ta'aloga fa'ata'ita'i, fa'amolemole ia mautinoa ia e malamalama i le natura ma le saogalemu o fa'amatalaga o le fa'alapotopotoga, ma mulimulita'i i fa'agaioiga fa'agaioiga ma faiga saogalemu.
