Iimpawu ze-Maleic anhydride
I-Maleic anhydride (eyaziwa nangokuthi yi-cis-butenedioic anhydride) yikristalu emhlophe efana nenalithi. Ifomula yayo yamamolekhyuli ngu-C4H2O3.
, enesisindo samamolekhyuli esingu-98.06. Inendawo yokuncibilika engu-52.8°C, izinga lokubilisa engu-202°C, iphuzu lokukhanya elingu-103°C, kanye nokuminyana okungu-1.314. I-Maleic anhydride kulula ukuyenza ibe phezulu, begodu incibilika emanzini, ema-alcohols kanye nama-ester, ngesikhathi incibilika kancani ku-carbon tetrachloride kanye ne-petroli ehlanzekileko. Kokubili ithuli nomhwamuko we-maleic anhydride kuyavutha begodu kuyaqhuma; zicasula abantu begodu zingabanga ukutjhiswa kwesikhumba.

Kubayini ukhetha i-Maleic Anhydride? Ngumgogodla we-polyester resin ephezulu, begodu ivula amakhemikhali ahlukahlukeneko (i-BDO, i-THF, njll.). Sithumelele umlayezo nje ukuhlola iinsombululo ze-MA ezilungiselelwe ibhizinisi lakho!
