Incazelo
I-Dibutyl phthalate, eyaziwa nangokuthi i-dibutyl phthalate noma i-dibutyl phthalate, isiNgisi: I-Dibutylphthalate, iwuketshezi olunamafutha angenambala olubonisa ngale olunamandla adonsela phansi angu-1.045 (21°C) nendawo abilayo angu-340°C, engancibiliki emanzini, encibilika emanzini futhi i-volatile Izakhiwo ziphansi kakhulu, kodwa zincibilika kalula kuzincibilikisi zemvelo njenge-ethanol, i-ether, i-acetone ne-benzene, futhi iphinde ixubane nama-hydrocarbons amaningi.I-Dibutyl phthalate (DBP), i-dioctyl phthalate (DOP) kanye ne-diisobutyl phthalate (DIBP) amapulasitiki amathathu ajwayelekile, okungamapulasitiki, irabha yokwenziwa kanye nesikhumba sokwenziwa, njll. amapulasitiki asetshenziswa kakhulu.Itholakala nge-thermal esterification ye-phthalic anhydride ne-n-butanol.
Chemical Properties
Uketshezi olunamafutha abonakalayo angenambala olunephunga elimnandi kancane.Incibilika kuzincibilikisi ezivamile eziphilayo nama-hydrocarbon.
Isicelo
-Isetshenziswa njenge-plasticizer ye-nitrocellulose, i-cellulose acetate, i-polyvinyl chloride, njll. Lo mkhiqizo uyi-plasticizer.Inamandla anamandla okuncibilika kuma-resin ahlukahlukene.
-Isetshenziselwa ukucubungula i-PVC, ingadlulisela ukuthamba okuhle emikhiqizweni.Ngenxa yokushibhile nokuhle ukucutshungulwa kwayo, isetshenziswa kabanzi, icishe ilingane ne-DOP.Kodwa-ke, ukuguquguquka nokukhipha amanzi kukhulu kakhulu, ngakho-ke ukuqina komkhiqizo kumpofu, futhi ukusetshenziswa kwawo kufanele kuvinjelwe kancane kancane.Lo mkhiqizo uyi-plasticizer enhle kakhulu ye-nitrocellulose futhi unamandla aqinile we-gelling.
-Isetshenziselwa ukugqoka i-nitrocellulose, inomphumela omuhle kakhulu wokuthambisa.Ukuzinza okuhle kakhulu, ukumelana nokuguquguquka, ukunamathela nokumelana namanzi.Ngaphezu kwalokho, umkhiqizo ungasetshenziswa njenge-plasticizer ye-polyvinyl acetate, i-alkyd resin, i-ethyl cellulose ne-neoprene, futhi ingasetshenziswa ekwenzeni amapende, ama-adhesives, isikhumba sokwenziwa, oyinki bokunyathelisa, ingilazi yokuphepha, i-celluloid, odayi, izibulala-zinambuzane. , izincibilikisi zephunga elimnandi, okokugcoba kwendwangu, njll.
- Njenge-plasticizer ye-cellulose ester, usawoti kanye nerabha yemvelo, i-polystyrene;ukwenza i-polyvinyl chloride nama-copolymers ayo ukumelana nokubanda ku-organic synthesis, izithasiselo ze-ion selective electrode, izinyibilikisi, izibulala-zinambuzane, ama-plasticizers, i-Gas chromatography uketshezi olumile (izinga lokushisa eliphezulu lokusetshenziswa elingu-100 ℃, i-solvent iyi-acetone, i-benzene, i-dichloromethane, i-ethanol ekhethiwe), i-ethanol ekhethiwe ukuhlukaniswa kwezinhlanganisela ezinamakha, ama-unsaturated compounds, i-terpene compounds nezinhlanganisela ezihlukahlukene eziqukethe umoya-mpilo (utshwala, i-aldehydes, i-ketones, i-esters, njll.).
