Ukubuka Konke Kwemakethe
Imakethe ye-phthalic anhydride eyinhloko ivaliwe ngamanani azinzile kakhulu kodwa kwehle kancane esikhathini sokuhweba sakamuva. Phezulu, intengo ye-orthoxylene yezinto zokusetshenziswa ihlale izinzile, kuyilapho amanani e-naphthalene yezimboni ekhombisa ubuthakathaka obuncane. Ukusekelwa kwezindleko sekukonke bekulinganiselwe. Abathengi abasezansi babonise ukuncipha kwentshiseko yokuthenga, okwaholela esimweni sokuhweba esiphansi.
Izici Eziyinhloko Ezithonya Ukunyakaza Kwamanani Kwamanje
* **Izindleko:** Amanani ezinto ezisetshenziswayo ezibalulekile, i-orthoxylene, ahlala eqinile, kuyilapho imakethe ye-naphthalene yezimboni isebenza ngokuzinzile kuya kokubuthakathaka. Lokhu kwaholela ekusekelweni okulinganiselwe kwezindleko zokukhiqizwa kwe-phthalic anhydride.
* **Ukunikezwa:** Amazinga okunikezwa ahlala engashintshile. Ngenkathi amanye amayunithi okukhiqiza elungiswa ngokuhleliwe, ezinye izikhungo ezazimiswe ngaphambilini zaqala ukusebenza.
* **Isidingo:** Izimo ezihambisana nesidingo zancipha. Amanani okusebenza ezimbonini ezingezansi ayezinzile aze ancipha kancane, futhi inzalo yokuthenga emakethe ngokuvamile yayithambile.
**Umbono Wemakethe**
Imakethe ye-phthalic anhydride kulindeleke ukuthi ibone (umsebenzi oncishisiwe/ongakhanyi kahle) maduze nje. Intengo ye-orthoxylene kulindeleke ukuthi ihlale izinzile, kuyilapho amanani e-naphthalene yezimboni angaqhubeka nomkhuba wawo ozinzile kuya kobuthakathaka, agcine ingcindezi yezindleko ephakathi nendawo. Njengoba amazinga okusebenza kwezinye imikhakha engezansi engase yehle futhi intshiseko yokuthenga ingase ihlale ilinganiselwe, umsebenzi wokuhweba ubikezelwe ukuthi uzohlala (uthule). Ngenxa yalokho, amanani e-phthalic anhydride abikezelwa ukuthi azohweba ngendlela (encishisiwe/engakhanyi kahle).
