Folasaga
Trans-4-bromo-2-butenoic acid methyl ester o se vai e leai ni lanu ma se manogi faapitoa. E iai lona mamafa e tusa ma le 1.49g/cm3, o le mea e pupuna ai e tusa ma le 171-172°C, ma le mea moli e tusa ma le 67°C. E le mafai ona solu i totonu o le vai i le vevela o le potu, ae e faʻafefeteina ma soʻo faʻalagona pei ole ethanol, eter, ma isi.
Fa'aaogā:
Trans-4-bromo-2-butenoic acid methyl ester e masani ona faʻaaogaina e avea o se vaeluagalemu i gaioiga faʻasologa o meaola. E mafai ona faʻaaogaina mo le faʻapipiʻiina o isi mea faʻapitoa, mo se faʻataʻitaʻiga mo le tuʻufaʻatasia o mea faʻapipiʻi i vailaʻau kemisi ma vailaau faʻasaina.
Sauniuniga auala:
Trans-4-bromo-2-butenoic acid methyl ester e masani ona saunia e ala i le tali atu o le bromination ma le esterification reaction. O le Butene e muamua fa'atasi ma le bromine e maua ai le 4-bromo-2-butene, ona fa'amama lea i le methanol e maua ai le trans-4-bromo-2-butenoic acid methyl ester.
Fa'amatalaga Saogalemu:
Trans-4-bromo-2-butenoic acid methyl ester o se ituaiga o solvent organic ma vailaʻau mataʻutia, lea ei ai se tulaga lamatia. E ita ma pala, ma fa'afeso'ota'i ma le pa'u, mata po'o le manava manava e mafai ona fa'aitaitagofie ma manu'a. E tatau ona 'alofia le fa'afeso'ota'i tu'usa'o a'o fa'aoga, ma e tatau ona ave le puipuiga o le manava talafeagai ma ofu puipui. E le gata i lea, e tatau ona faʻaeteete e aloese mai le faʻafesoʻotaʻi ma vailaʻau faʻamaʻi ma vailaʻau malosi i le taimi o le teuina e puipuia ai faʻalavelave mataʻutia. Afai e te manaʻomia le faʻaogaina o lenei faʻaoga, faʻamolemole faʻagaioi i totonu o se nofoaga saogalemu ma mulimulitaʻi i taualumaga saogalemu o galuega.
