Yini inchubo ye-Phthalic Anhydride Ngemkhicito Maleic Anhydride?

Inchubo Yemkhicito We-Phthalic Anhydride
Uma kukhicitwa i-phthalic i-anhydride kusuka ku-o-xylene, I-Maleic Anhydride ngumkhicito longaphansi (~ 5% wemphumela we-phthalic anhydride). Ngesikhatsi sekukhicita iphthalic anhydride, igesi yemsila wekuphendvula iyagezwa kwentela kususa tintfo letiphilako; loludzaka lwekugeza (lolucuketse i-maleic anhydride, i-benzoic acid lencane, kanye ne-phthalic acid) luyagcizelelwa, luhlanjululwe, bese lushiswa kute luphelele emanti—lokukhicita imikhicito ye-maleic anhydride.

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!
