He aha ngā whakamahinga o te maleic anhydride?

Ko te anhydride maleic (e kiia ana ko te anhydride cis-butenedioic) he rauemi mata matū waro matua, ko te tuatoru o ngā anhydride (whai muri i te anhydride phthalic me te anhydride acetic). E whakamahia ana hei hanga polyesters kāore i te mākū me ngā kapia alkyd, ā, ka kitea hoki ngā tono i roto i ngā patupatu, ngā paninga, ngā waituhi, ngā tāpiringa hinu whakahinuhinu, ngā matū hanga pepa, ngā kaihoko whakaoti kakahu, me ngā surfactants. Ko ngā hua mai i te anhydride maleic ko te 1,4-butanediol, γ-butyrolactone, tetrahydrofuran, te waikawa maleic, te waikawa fumaric, me te tetrahydrophthalic anhydride—he matū waro me ngā matū pai katoa.

He aha koe i whiriwhiri ai i te Maleic Anhydride? Koinei te pou tuarā o ngā kapia polyester kounga teitei, ā, ka wetewetehia hoki ngā matū rerekē o muri mai (BDO, THF, me ētahi atu). Tukua mai he karere inaianei hei tūhura i ngā otinga MA kua whakaritea mō tō pakihi!
