Iphrofayili ye I-Maleic Anhydride
Timphahla te-Maleic anhydride
I-Maleic anhydride (lephindze yatiwe ngekutsi yi-cis-butenedioic anhydride) yikristalu lemhlophe lefana nenyaliti ye-orthorhombic. Ifomula yayo yemamolekhyuli ngu C .4H2O3.
, ngesisindvo se-molecule lengu-98.06. Inendzawo yekuncibilika lengu 52.8°C, indzawo yekubila lengu 202°C, indzawo yekukhanya lengu 103°C, kanye nekucina lokuhlobene kwa 1.314. iMaleic anhydride kulula kukhuphuka, futsi incibilika emantini, tjwala kanye nema esters, kantsi incibilika kancane ku carbon tetrachloride kanye naphethiloli lohlobile. Kokubili lutfuli kanye nemphunga we maleic anhydride kuyavutsa futsi kuyaqhuma; tiyacasula bantfu futsi tingabanga kushiswa kwesikhumba.

Kungani ukhetsa i-Maleic Anhydride? Ngumgogodla wema resin e polyester langagcwaliswa lasetulu, kanye nekuvula emakhemikhali lahlukahlukene lasehla (BDO, THF, njll). Sitfumele umlayeto nyalo kute uhlole tisombululo te-MA letilungiselelwe ibhizinisi lakho!
