Indlela ye-Maleic Anhydride Benzene isebenza kanjani?

I-Anhydride yamaMaleic Indlela ye-benzene
I-Anhydride yamaMaleic Indlela ye-C4 fraction. Le ndlela isebenzisa izingxenye ezisebenzayo (njenge-butene, i-butadiene) kuma-C4 fractions njengezinto zokusetshenziswa, ezisabela nomoya (noma i-oxygen) ekusabeleni kwe-gas-phase oxidation ngaphansi kwesenzo se-V₂O₅-P₂O₅ catalyst ukukhiqiza i-maleic anhydride. Ngenxa yezindleko eziphezulu zezinto zokusetshenziswa kanye nesivuno esiphansi, le ndlela isusiwe.
Indlela yomkhiqizo we-anhydride ye-Maleic Anhydride Ngesikhathi sokukhiqizwa kwe-anhydride ye-phthalic evela ku-o-xylene, inani elithile le-anhydride ye-maleic lingatholakala njengomkhiqizo we-by-product, elibalelwa cishe ku-5% womkhiqizo we-anhydride ye-phthalic.

Kungani ukhetha i-Maleic Anhydride? Iwumgogodla wama-resin e-polyester angagcwele aphezulu, futhi ivula amakhemikhali ahlukahlukene angaphansi (i-BDO, i-THF, njll.). Sithumelele umyalezo manje ukuze uhlole izixazululo ze-MA ezenzelwe ibhizinisi lakho!
