Fa'atatauga

Tetrabutylurea (TBU)ose fa'afefiloi e fa'aaoga muamua e fai ma so'o ma fa'afofoga i le tele o fa'aoga vaila'au. Fa'amatalaga sili atu, fa'amolemole va'ai ile mulimuli:
 
1. Solvent in organic synthesis:1,1,3,3-Tetrabutylurea e masani ona faʻaaogaina e avea o se solvent mo gaioiga faʻasolosolo, aemaise lava i le faʻapipiʻiina o mea faʻapitoa eseese. O lona gafatia e faʻamavae ai le tele o mea polar ma mea e le o polar e faʻaaogaina tele i totonu o fale suʻesuʻe.
 
2. Aveese ma Tuueseese:TETRA-N-BUTYLUREA e mafai ona fa'aoga ile sua-suava fa'agasologa ole su'ega e tu'u'ese'ese ai fa'aputuga fa'atatau ile latou solubility. E sili ona aoga i le su'eina o ni u'amea u'amea ma mea fa'aola mai fa'afefiloi.
 
3. Reagents i gaioiga fa'a-kemikolo:N,N,N',N'-Tetra-n-butylurea e mafai ona fa'aaogaina e fai ma mea fa'afoma'i i gaioiga fa'a-kemikolo eseese, e aofia ai gaioiga e aofia ai le sui nucleophilic ma isi suiga fa'aletino.
 
4. Caalyst carrier:I nisi fa'agaioiga fa'anatura, e mafai ona fa'aogaina le TBU e fai ma ala fa'aulu e fa'aleleia ai lona solubility ma le fa'agaoioiga i le fa'afefiloiga tali.
 
5. Talosaga su'esu'e:N,N,N',N'-TETRA-N-BUTYLUREA o loʻo faʻaaogaina i siosiomaga suʻesuʻe, aemaise lava suʻesuʻega e aʻafia ai aʻafiaga o le fofo, vai ionic ma isi vaega faʻaletino ma vailaʻau.
 
6. Polymer Chemistry:N,N,N',N'-tetrabutyl-;tetrabutyl-ure e mafai foi ona faʻaaogaina i polymer kemisi ma e mafai ona faʻaaogaina e avea o se solvent poʻo se faʻaopoopoga i le polymer synthesis.

E fa'afefea ona teu Tetrabutylurea?

Tetrabutylurea (TBU) e tatau ona teuina lelei ina ia faatumauina lona mautu ma puipuia soʻo se lamatiaga e ono tulaʻi mai. O nisi nei o taʻiala mo le teuina o tetrabutylurea:
 
1. Pusa:Teu le tetrabutyl urea i totonu o se atigipusa faʻamaufaʻailoga e puipuia ai le faʻaleagaina ma le faʻafefe. O le atigipusa e tatau ona faia i mea e fetaui ma solu faʻaletino, e pei o tioata poʻo nisi palasitika.
 
2. vevela:Teu le TBU i se nofoaga mālūlū ma mago e mamao ese mai le la ma le vevela. O le mea lelei, e tatau ona teuina i le vevela o le potu, ae o tulaga faʻapitoa e teu ai e mafai ona faʻalagolago i fautuaga a le gaosiga.
 
3. Savili:Ia fa'amautinoa o lo'o lelei le savili o nofoaga e teu ai ina ia fa'aitiitia ai le fa'aputuina o so'o se ausa e ono tu'u mai.
 
4. Tuuese mai mea e le fetaui:Taofi le tetrabutyl urea mai vailaʻau malolosi, acids ma isi mea e le fetaui e puipuia ai soʻo se gaioiga matautia.
