Ko te anhydride maleic, e mōhiotia ana ko te "anhydride maleic", ko te anhydride o te waikawa maleic. He totoka kore tae, he mā rānei, he reka kawa i te pāmahana rūma, ko te tauira ngota o C4H2O3. Ko te taumaha ngota 98.06. Ka whiwhihia ngā tioata āhua ngira mai i te chloroform, i te ether rānei. Te ira rewa 60℃, te ira kohua 82℃ (1.Chemicalbook8665kPa), te mātotoru whanaunga 1.31460. Ka wairewa ki te acetone, te chloroform, te ether, he paku wairewa ki te petroleum ether. Ka wairewa ki te wai hei hanga waikawa cis-butenedioic, ka wairewa ki te waipiro hei hanga esters, ā, ka taea te tauhohe ki ngā matū kei roto ngā hononga takirua honohono hei hanga i te hanganga diene. He paitini, he tino whakapataritari ki ngā kiriuhi mucous.

Ngā Whakamahinga:

Whakamahia hei rauemi mata mō te hanga o te 1,4-butanediol, γ-butyrolactone, tetrahydrofuran, te waikawa succinic, te kapia polyester unsaturated, te kapia alkyd, me ētahi atu. E whakamahia ana hoki i roto i te rongoā me ngā patupatu.

Ngā tikanga whakaputa

Ko ngā tikanga whakaputa matua o te anhydride maleic ko te whakakōkī benzene, te whakakōkī butene me te whakakōkī n-butane, engari ko te whakakōkī benzene tonu te tikanga matua. 1. Tikanga whakakōkī benzene Ka pāngia te Benzene e te tauhohenga whakakōkī i roto i te moenga pumau i raro i te mahi a te whakakōkī raupapa V-Mo-P hei whakaputa i te anhydride maleic, ā, ko te pāmahana tauhohenga he 365°C (ka taea hoki e te moenga tauhohenga te whakamahi i te moenga kohua, engari he teitei te kai o Chemicalbook). Kātahi ka mimitia ki te wai hei whakaputa i te waikawa maleic, kātahi ka mahia te whakamaroketanga azeotropic me te whakatōtō, ā, ka whiwhi i te hua oti mā te waru. 2. Tikanga whakakōkī butane (butene rānei) Ka whakakōkīhia te butane (butene rānei) e te hau, e te hāora rānei i raro i te mahi a te whakakōkī V-Mo hei whakaputa i te anhydride maleic, ā, ko te pāmahana tauhohenga he 350-400°C. Kātahi ka mimitia ki te wai, ka whakamarokehia, ka whakangawarihia kia whiwhi i te hua oti.
