He aha nā hoʻohana o ka maleic anhydride?

ʻO ka maleic anhydride (i kapa ʻia hoʻi he cis-butenedioic anhydride) kahi mea maka kemika organik koʻikoʻi, ʻo ia ke kolu o ka helu ma waena o nā anhydrides (ma hope o ka phthalic anhydride a me ka acetic anhydride). Hoʻohana nui ʻia ia e hana i nā polyesters unsaturated a me nā resins alkyd, a loaʻa pū kekahi mau noi i nā pesticides, nā uhi, nā ʻīnika, nā mea hoʻohui lubricant, nā kemika hana pepa, nā mea hoʻopau lole, a me nā surfactants. ʻO nā mea i loaʻa mai ka maleic anhydride e komo pū me 1,4-butanediol, γ-butyrolactone, tetrahydrofuran, maleic acid, fumaric acid, a me tetrahydrophthalic anhydride—nā kemika organik a me nā kemika maikaʻi a pau.

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!
