Ngiziphi izakhiwo ezibonakalako nezamakhemikhali ze-maleic anhydride?

I-Maleic Anhydride Izakhiwo ezibonakalako nezamakhemikhali: Emazingeni womtjhiso wegumbi, ibonakala njengeenhluthu ezimhlophe, iinalithi, ama-flakes, ama-rod, ama-lumps nofana amabhlogo, ngokucasuka okukhulu. Ukuminyana okuhlobeneko: 1.48; Indawo yokuncibilika: 52.8°C; Indawo yokubilisa: 202.2°C. I-Maleic Anhydrid nayo ingakhula khulu emazingeni womtjhiso aphasi (60-80°C). Incibilika ku-ethanol, i-ether kanye ne-acetone; ihlangana namanzi ukwakha i-maleic acid. Ivutha, begodu umhwamuko wayo nethuli kungenza imihlanganisela eqhumako lokha nayihlanganiswa nomoya.
Izinga eliphezulu lepahla (GB-3676-92)
Ukubukeka I-flake emhlophe, eneenhlamvu
Ukuhlanzeka kwe-Maleic Anhydrid ≥99.5%
Indawo yokwenza ikristalu ≥52.4°C
Umbala wokuncibilika ≤25Pt-Co
Okuqukethwe mlotha ≤0.005%
Okuqukethwe yi-ayini ≤5ppm

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!
