Fumaric acid waxaa loo isticmaali karaa nidaamiyaha aashitada

Fumaric acid, sidoo kale loo yaqaan fumaric acid, violet acid ama lichenic acid, kuwaas oo ah fumaric acid (IUPAC name (E) -butenedioic acid), waa kareem aan midab lahayn, ololaya oo ka kooban asiidh Carboxylic oo ka soo jeeda butene. Gubashada fumaric acid waxay sii deysaa qiiqa anhydride-ka lab ee xanaaqa leh. Waxay dhadhamisaa sida miro oo kale waxaana laga helaa Corydalis, Boletus, Lichens, iyo Icelandic Nori.

faahfaahinta alaabta

Sharaxaada

Fumaric acid waxaa loo isticmaalaa soo saarista xabagta polyesterka ee aan saturated lahayn. Noocyada noocaan ah waxaa lagu gartaa caabbinta kiimikada wanaagsan iyo caabbinta kulaylka; copolymer ee fumaric acid iyo vinyl acetate waa xabag wanaagsan. Copolymer leh styrene waa alaabta ceeriin ee wax soo saarka FRP. Balaastiijiyaha ay samaysay fumaric acid waa mid aan sun ahayn waxaana loo isticmaali karaa vinyl acetate cinjirka cuntada. Alaabtani waa dhexdhexaad kiimiko oo wanaagsan sida dawooyinka iyo wakiilka biliijing indhaha. Waxaa loo isticmaalaa soo saarista antidote dimercaptosuccinic acid ee warshadaha dawooyinka. Aashitada fumaric waxaa lagu dabar gooyaa sodium carbonate si loo helo sodium fumarate ([17013-01-3]), ka dibna lagu beddelo ferrous sulfate si loo helo fumarate birta, taas oo loo isticmaalo in lagu daaweeyo dhiig-yaraanta unugyada cas ee dhiigga yar oo leh dawooyin qani ku ah birta. Alaabtan waxa loo isticmaalaa sidii cunto lagu daro-dhanaan, oo loo isticmaalo cabitaannada soo cusboonaysiinta, nacnaca miraha, jelly, jalaatada, iwm., kuwaas oo intooda badan lagu daro wakiilka dhanaan citric acid. Cusbada monosodium ee ay samaysay falcelinta fumaric acid iyo sodium hydroxide, Waxa kale oo loo isticmaalaa xawaash dhanaan iyo dhexdhexaad u ah resin synthetic iyo mordant.

Codsiga

Cunto inta badan loo isticmaalo hilibka, habaynta wax soo saarka kalluunka iyo wixii la mid ah. Fumaric acid waxaa loo isticmaali karaa nidaamiyaha aashitada, acidifier, antioxidant, dhiirrigeliye milix iyo uunsi. Alaabtani waxay leedahay saameyn xoog leh si ay u ilaaliso xalka aqueous ee ku saabsan pH3.0, waxayna leedahay door muhiim ah oo ka hortagga bakteeriyada iyo caariyaysiga, isla mar ahaantaana, waxay leedahay dhadhan astringent, waa mid ka mid ah acids adag ugu acidic, heerka nuugista hooseeya, waxayna caawisaa in la kordhiyo nolosha shelf ee alaabta budada. Marka fumaric acid loo beddelo fumarate sodium, milanka biyaha iyo dhadhanka ayaa fiican.
