Folasaga
methyl hydrogen azelate, e lauiloa foi o le polycarboxylate, o se polymer mole mole maualuga. E iai ona uiga nei:
1. Mea fa'aletino: methyl hydrogen azelate e leai se lanu po'o le moli samasama vai, ma solubility lelei, soluble i le vai, ava malosi ma solvents organic.
2. Mea tau vailaʻau: methyl hydrogen azelate o se faʻapipiʻi ester ma maualuga le mautu ma vailaʻau teteʻe. E mafai ona fa'asusu i le azelaic acid ma le methanol.
O faʻaoga autu o le methyl hydrogen azelate e aofia ai:
1. Polymer sauniuniga: methyl hydrogen azelate e mafai ona polymerized ma isi monomers e saunia polymers mole maualuga. O nei polymers o loʻo i ai mea sili ona lelei ma e mafai ona faʻaaogaina i pisinisi eseese e pei o paʻu, kelu, palasitika, filo, ma isi.
2. Surfactant: methyl hydrogen azelate e mafai ona faʻaaogaina e pei o le emulsifier, dispersant ma le susu, faʻaaogaina lautele i mea teuteu, vailaʻau ma mea tau tausiga a le tagata lava ia ma isi fanua.
O auala mo le saunia o le methyl hydrogen azelate e masani lava e pei ona taua i lalo:
1. Transesterification tali: transesterification tali e faia i le ava malosi nonyl ma methyl formate i le i ai o le acid catalyst e maua ai le methyl hydrogen azelate.
2. Fa'asagaga fa'ama'i sa'o: esterification o le nonanol ma le formate i lalo o le fa'agaioiga o le fa'ama'i fa'ama'i e gaosia ai le methyl hydrogen azelate.
Ia matau faamatalaga saogalemu nei pe a faaaoga ma tagofia le methyl hydrogen azelate:
1. O le methyl hydrogen azelate e ita ma e tatau ona fufulu vave pe a pa'i i le pa'u ma mata.
2. Aloese mai le manavaina o le ausa o le methyl hydrogen azelate ma faʻaoga i se nofoaga faʻafefe lelei.
3. methyl hydrogen azelate e maualalo le oona, ae o le umi ma le tele o le faʻaalia e mafai ona i ai se aafiaga i le soifua maloloina, ma e tatau ona aloese mai le tele o le faʻaalia.
4. Pe a teuina ma felauaiga methyl hydrogen azelate, taofi ese mai le afi ma le vevela maualuga e puipuia ai le lamatiaga o le mu ma le pa.
Faamolemole ia matau a'o le'i faaaogaina le methyl hydrogen azelate po'o so'o se vaila'au, e tatau ona e faitau ma le fa'aeteete ma mulimulita'i i faiga talafeagai mo le saogalemu.
