Maleic acid CAS 110-16-7
ʻO ka maleic acid kahi aniani kala ʻole monoclinic me ka ʻono astringent. Hiki ke hoʻoheheʻe ʻia i ka wai, ethanol a me ka acetone, hiki ʻole ke hoʻoheheʻe ʻia i loko o ka benzene. ʻO ka ʻakika maleic, ka ʻakika maleic, he ʻakika dicarboxylic, he pūhui mea ola i loaʻa i ʻelua mau pūʻulu hana carboxylic acid. ʻO ka ʻakika maleic a me ka ʻakika fumaric (waika fumaric) he isomers cis-trans o kekahi i kekahi. Hoʻohana mau ʻia ka ʻakika maleic no ka hoʻomākaukau ʻana i ka waikawa fumaric, ʻo ka maleic acid's anhydride he maleic anhydride, ke hoʻohālikelike ʻia me kāna acid anhydride, ʻoi aku ka liʻiliʻi o ka maleic acid.
