Yintoni i-Maleic acid CAS 110-16-7?

Iasidi ye-Maleic yikristale engenambala ye-monoclinic kunye nencasa ye-astringent. Inyibilika emanzini, ethanol kunye neacetone, ayinyibiliki kwibenzene. I-asidi ye-Maleic, i-maleic acid, i-dicarboxylic acid, i-organic compound equkethe amaqela amabini asebenzayo e-carboxylic acid. I-asidi ye-Maleic kunye ne-fumaric acid (i-fumaric acid) zi-cis-trans isomers enye kwenye. Maleic acid ngokuqhelekileyo isetyenziselwa ukulungiselela i-fumaric acid, i-anhydride ye-maleic yi-anhydride ye-maleic, xa kuthelekiswa ne-anhydride yayo ye-asidi, i-maleic acid inesicelo esincinci.

Isicelo

I-asidi ye-Maleic iyacotha i-rancidity yeeoli kunye namafutha kwaye ingasetyenziselwa njengento yokugcina kunye ne-organic synthesis yeeoli kunye namafutha. Maleic acid, eyaziwa ngokuba asidi maleic, ikakhulu isetyenziswa kwimveliso amachiza maratha, darcinone, zokwenziwa polyester resin unsaturated, pine bhalsam, tartaric acid, fumaric acid, succinic acid kunye nezinye iimveliso, kodwa ikwasetyenziswa amayeza, ukutyabeka, ukutya kunye noshicilelo kunye ukudaya preservative AIDS kunye nokudaya.
