Thepa ea 'mele le ea lik'hemik'hale ea maleic anhydride ke efe?
Maleic Anhydride Thepa ea 'mele le ea lik'hemik'hale: Mochesong oa kamore, e hlaha e le li-granule tse tšoeu, linalete, li-flakes, lithupa, li-klips kapa li-block, tse nang le ho teneha ho matla. Bongata bo amanang: 1.48; Sebaka sa ho qhibiliha: 52.8°C; Sebaka sa ho belisa: 202.2°C. Maleic Anhydrid e ka boela ea phahama mochesong o tlase (60-80°C). E qhibiliha ka har'a ethanol, ether le acetone; e arabela le metsi ho etsa maleic acid. E ka tuka, 'me mouoane oa eona le lerōle li ka etsa metsoako e phatlohang ha li kopantsoe le moea.
