Asidi ya Trans-Butenedioic
(Fumaric Acid)
Mafotokozedwe:Asidi ya trans-butenedioic ili ndi ntchito ya bacteriostatic komanso antiseptic. Ingagwiritsidwe ntchito ngati acidulant, acidity regulator, acidifier；
Katundu:Ufa woyera wopanda fungo kapena, wokhala ndi kukoma kokoma komwe kumakhala kolimba ngati citric acid ka 1.5. Umasungunuka mu ethanol (5.76g/100g, 30°c), umasungunuka pang'ono m'madzi (0.63g/100ml, 25°c) ndi mu ether, ndipo umasungunuka pang'ono mu chloroform. Ulibe hygroscopicity, ndipo umasungunuka bwino pa 200°c. Malo otentha: 290°c (amawola). Udzasanduka maleic anhydride pa 230°c, ndipo umapanga DL-malic acid ngati uwiritsidwa ndi madzi.
Kagwiritsidwe:Asidi ya Trans-butenedioic ili ndi ntchito ya bacteriostatic komanso antiseptic. Itha kugwiritsidwa ntchito ngati acidulant, acidity regulator, acidifier, thermal-oxidative resist assistant, celling accelerant ndi spice. Imagwiritsidwa ntchito kwambiri popanga zakumwa zosiyanasiyana za carbonic acid, vinyo, chakumwa cholimba chokhazikika, ayisikilimu ndi zakudya zina zozizira. Itha kulowa m'malo mwa malic acid, citric acid, chifukwa acidity yake ndi nthawi 1.5 kuposa ya citric acid. Fumaric acid ingagwiritsidwe ntchito ngati PHAR intermediate and optical bleaching agent, yomwe imagwiritsidwanso ntchito popanga unsaturated polyester resin.
