Malonic acid CAS 141-82-2
ʻO ka malonic acid he mea keʻokeʻo keʻokeʻo. Hiki ke hoʻoheheʻe i ka wai, hiki ke hoʻoheheʻe ʻia i ka ethanol, ether, a me pyridine. ʻO ka crystallization mai ka ethanol he aniani keʻokeʻo triclinic. ʻO 104.06 ka paona molekala pili. Māmā pili 1.631 (15 ℃). Ka helu hehee 135.6 ℃. E hoʻoheheʻe ʻia i loko o ka ʻakika acetic a me ka carbon dioxide ma 140 ℃.
