Nā Waiwai Anhydride Maleic
ʻO ka maleic anhydride (ʻike ʻia hoʻi ʻo cis-butenedioic anhydride) he kristal keʻokeʻo e like me ke nila orthorhombic. ʻO kona ʻano molekala ʻo C4H2O3.
, me ke kaumaha molekala o 98.06. He 52.8°C kona wahi heheʻe, 202°C ka wahi paila, 103°C ka wahi lapalapa, a me 1.314 ka nui o ka mānoanoa. He maʻalahi ka hoʻoheheʻe ʻana o ka maleic anhydride, a hiki ke hoʻoheheʻe ʻia i loko o ka wai, nā waiʻona a me nā esters, ʻoiai he mea hoʻoheheʻe iki ia i loko o ke kalapona tetrachloride a me ka gasoline maka. He lapalapa a pahū ka lepo a me ka mahu o ka maleic anhydride; he mea hoʻonāukiuki ia i nā kānaka a hiki ke hoʻoulu i ke kuni i ka ʻili.

No ke aha e koho ai i ka Maleic Anhydride? ʻO ia ke kumu o nā resins polyester unsaturated kiʻekiʻe, a wehe pū ia i nā kemika like ʻole ma hope (BDO, THF, a pēlā aku). E leka mai iā mākou i kēia manawa e ʻimi i nā hoʻonā MA i hana kūikawā ʻia no kāu ʻoihana!
