He aha te waikawa Maleic CAS 110-16-7?

Ko te waikawa maleic he karaihe taekore monoclinic me te reka astringent. Wairewa ki te wai, waiwaro me te acetone, karekau ki te benzene. Ko te waikawa maleic, te waikawa maleic, he waikawa dicarboxylic, he puhui waro kei roto e rua nga roopu mahi waikawa carboxylic. Ko te waikawa maleic me te waikawa fumaric (waikawa fumaric) he inerite cis-trans o tetahi ki tetahi. Ka whakamahia te waikawa maleic ki te whakarite waikawa fumaric, he anhydride maleic te anhydride waikawa maleic, ka whakatauritea ki tana anhydride waikawa, he iti ake te tono o te waikawa maleic.
