Ukufanisa
I-Dibutyl perthalate, eyaziwa nangokuthi i-Dibutyl phthalate noma i-Dibutyl perthalate, isiNgisi: I-DiButylphHthate, iyindlela evuthayo enamafutha engu-340 ° C, kepha ancibilike kakhulu ezindaweni ezinamanzi aphansi kakhulu, kepha ancibilike kalula ku-solvents ye-organic efana I-Ethanol, ether, i-acetone ne-benzene, futhi futhi ayikungezinhle kakhulu ngama-hydrocarbons amaningi. I-Dibutyl phthalate (DBP), i-dioctyl perthalate (dop) ne-diisobuttl perthalate (dibp) ngamapulasitiki ajwayelekile, okuyi-plastitics, irabha yokwenziwa kanye nesikhumba sokufakelwa. Itholakala ngokuchazwa okushisayo kwe-phthalic anhydride ne-n-Butanol.
Izakhiwo Zamakhemikhali
Uketshezi olungenawo umbala onamafutha ngephunga elimnandi elinomoya. Incibilika kuma-solvents ajwayelekile we-organic kanye ne-hydrocarbons.
Isicelo
-Ukusebenza njengesositiki se-nitrocellose, i-cellulose acetate, polyvinyl chloride, njll. Lo mkhiqizo ungumkhiqizo. Inamandla okuqeda amandla kuma-resins ahlukahlukene.
-Sebenziswe ukucubungula i-PVC, kungadlulisela ukuthamba okuhle kwimikhiqizo. Ngenxa yokucubungula kwayo okushibhile kakhulu futhi okuhle, kusetshenziswa kabanzi, kucishe kube okulingana ne-dop. Kodwa-ke, ukukhishwa okuguquguqukayo kanye nokukhishwa kwamanzi kukhulu, ngakho ukuqina komkhiqizo kumpofu, futhi ukusetshenziswa kwayo kufanele kuvinjelwe kancane kancane. Lo mkhiqizo uyipulasitiki enhle kakhulu ye-nitrocellulose futhi unekhono eliqinile lokucekela phansi.
-Sebenziswe izigqoko ze-nitrocellulose, unomphumela omuhle kakhulu wokuthambisa. Ukuqina okuhle, ukumelana okuguquguqukayo, ukunamathela kanye nokumelana kwamanzi. Ngaphezu kwalokho, umkhiqizo ungasetshenziswa njenge-spistizer ye-polyvinyl acetate, i-alkyd resin, i-ethyl cellulose ne-inks, futhi nayo ingasetshenziswa emithini yokubulala izinambuzane, ama-solces wendwangu, njll.
- Njengomhlaka wepulasitiki we-cellulose ester, usawoti kanye nerabha yemvelo, polystyrene; Ukwenza i-polyvinyl chloride namaphoyisa awo ama-copolymers amelana nama-organic synthesis, izithasiselo ze-electromay ezikhethiwe, izimbumbulu, amazinga okushisa angu-100 ℃, i-aceptizes, i-dichloronethane, ukuhlukaniswa kwamakhompiyutha amnandi, amakhompiyutha angenasisekelo, i-terpene Amakhompiyutha kanye namakhompiyutha aqukethe i-oksijini ahlukahlukene (ama-alcohols, ama-aldehydes, ama-ketones, ama-esters, njll).
