Asiti ea Fumaric e ka sebelisoa e le taolo ea acidity

Asiti ea Fumaric, eo hape e tsejoang e le fumaric acid, violet acid kapa lichenic acid, e leng fumaric acid (IUPAC name (E) -butenedioic acid), ke kristale e se nang mebala, e tukang e entsoeng ka Carboxylic acid e nkiloeng ho butene. Ho chesa fumaric acid ho nt?a mosi o halefisang oa maleic anhydride. E latsoeha joaloka litholoana 'me e fumaneha Corydalis, Boletus, Lichens le Icelandic Nori.

Asiti ea Fumaric e sebelisoa ho hlahisa li-resine tsa polyester tse sa tsitsang. Mofuta ona oa resin o khetholloa ke ho hanyetsa lik'hemik'hale tse ntle le ho hanyetsa mocheso; copolymer ea fumaric acid le vinyl acetate ke sekhomaretsi se setle. Copolymer e nang le styrene ke thepa e tala bakeng sa ho etsa FRP. Plastiki e entsoeng ka fumaric acid ha e na chefo 'me e ka sebelisoa bakeng sa vinyl acetate latex ha e kopana le lijo. Sehlahisoa sena ke lik'hemik'hale tse ntle tse mahareng tse kang moriana le optical bleaching agent. E sebelisoa ho hlahisa antidote dimercaptosuccinic acid indastering ea meriana. Asiti ea fumaric ha e sebetse ka sodium carbonate ho fumana sodium fumarate ( [17013-01-3]), ebe e nkeloa sebaka ke ferrous sulfate ho fumana iron fumarate, e sebelisetsoang ho phekola phokolo ea mali e nyenyane ea lisele tse khubelu tsa mali ka lithethefatsi tse nang le t?epe. Sehlahisoa sena se sebelisoa e le motsoako oa lijo-thollo, o sebelisoang ka lino tse khathollang, lipompong tsa litholoana, jelly, ice cream, joalo-joalo, tseo boholo ba tsona li sebelisoang hammoho le citric acid e bolila. Letsoai la monosodium le entsoeng ka karabelo ea fumaric acid le sodium hydroxide, E boetse e sebelisoa e le senoko se bolila le se mahareng bakeng sa resin ea maiketsetso le mordant.
