Kodi Maleic acid CAS 110-16-7 ndi chiyani?

Maleic asidi ndi monoclinic colorless crystal ndi kukoma kwa astringent. Kusungunuka m'madzi, ethanol ndi acetone, osasungunuka mu benzene. Maleic acid, maleic acid, ndi dicarboxylic acid, organic pawiri yomwe ili ndi magulu awiri a carboxylic acid. Maleic acid ndi fumaric acid (fumaric acid) ndi cis-trans isomers wina ndi mzake. Maleic acid amagwiritsidwa ntchito pokonzekera fumaric acid, maleic acid anhydride ndi maleic anhydride, poyerekeza ndi acid anhydride, maleic acid ali ndi ntchito zochepa.
