I-asidi ye-trans butenedioic inomsebenzi we-bacteriostatic kunye ne-antiseptic. Ingasetyenziswa njenge-acidulant, i-acid regulator, i-acidifier;
I-Trans-Butenedioic Acid
(I-Fumaric Acid)
Inkcazo:I-asidi ye-trans-butenedioic inomsebenzi we-bacteriostatic kunye ne-antiseptic. Ingasetyenziswa njenge-acidulant, i-acid regulator, i-acidifier；
Iipropati:Umgubo omhlophe ongenavumba okanye, onobumuncu obukhethekileyo obunamandla aphindwe kayi-1.5 ye-citric acid. Inyibilika kwi-ethanol (5.76g/100g,30°c), inyibilika kancinci emanzini (0.63g/100ml,25°c) nakwi-ether, kwaye inyibilika kancinci kwi-chloroform. Ayina-hygroscopicity, kwaye iya kunyibilika kwi-200°c. Iqondo lokubila: 290°c (ibola). Iya kujika ibe yi-maleic anhydride kwi-230°c, kwaye iya kuvelisa i-DL-malic acid ukuba ibilisiwe ngamanzi.
Ukusetyenziswa:I-asidi ye-Trans-butenedioic inomsebenzi we-bacteriostatic kunye ne-antiseptic. Ingasetyenziswa njenge-acidulant, i-acidifier, i-acidifier, i-thermal-oxidative resist assistant, i-curing accelerant kunye ne-spice. Isetyenziswa kakhulu ekuveliseni iziselo ezahlukeneyo ze-carbonic acid, iwayini, isiselo esiqinileyo esixineneyo, i-ayisikhrim kunye nezinye iziselo ezibandayo. Ingathatha indawo ye-malic acid, i-citric acid, kuba i-acidity yayo iphindwe kayi-1.5 kune-citric acid. I-Fumaric acid ingasetyenziswa njenge-PHAR intermediate kunye ne-optical bleaching agent, ikwasetyenziswa ekwenzeni i-resin ye-polyester engagcwaliyo.
