Dibutyl phthalate, also known as dibutyl phthalate or dibutyl phthalate, English: Dibutylphthalate, is a colorless transparent oily liquid with a specific gravity of 1.045 (21°C) and a boiling point of 340°C, insoluble in water, water-soluble and volatile The properties are very low, but it is easily soluble in organic solvents tankou etanòl, etè, asetòn ak benzèn, epi li se tou miscible ak pi idrokarbur. Dibutil ftalat (DBP), ftalat dioctyl (DOP) ak ftalat diisobutil (DIBP) se twa plastifyan ki pi komen yo, ki se plastik, kawotchou sentetik ak kwi atifisyèl, elatriye. Li se jwenn pa esterifikasyon tèmik nan anidrid ftalik ak N-Butanol.
San koulè transparan likid lwil ak yon ti kras aromat odè. Soluble nan komen Solvang òganik ak idrokarbur.
-Used kòm yon plastifyan pou nitrokeluloz, asetat karboksimetil, klori polyvinyl, elatriye pwodwi sa a se yon plastifyan. Li te gen pouvwa fò dissolve rezin divès kalite.
-Used pou pwosesis PVC, li ka separe bon tendres nan pwodwi yo. Paske nan pwosesis relativman bon mache ak bon li yo, li trè lajman itilize, prèske ekivalan a DOP. Sepandan, volatilité a ak ekstraksyon dlo yo relativman gwo, se konsa rezistans a nan pwodwi a se pòv, ak sèvi ak li yo ta dwe piti piti restriksyon. Pwodwi sa a se yon plastifyan ekselan nan nitrocellulose e li gen gwo kapasite jèl.
-Used pou penti nitrocellulose, gen yon trè bon efè adousi. Excellent estabilite, fleksib rezistans, adezyon ak rezistans dlo. Anplis de sa, ka pwodwi a dwe itilize kòm yon plastifyan pou polyvinyl acetate, alky résine, etilikolozik ak neoprene, epi yo ka tou gen pou itilize nan fabrike nan pentire, adhésifs, kwi atifisyèl, enprime lank, glas sekirite, celluloid, koloran, pestisid, solvants parfen, grès twal twal, eluloid, koloran, pestisid, solvants parfen, grès twal lubrifyan, menm jan an twal, kolye, pestisid, solvants parfen, grès twal twal, lubrifyan twal.
- kòm yon plastifyan pou èskarit, sèl ak kawotchou natirèl, polystyrène; to make polyvinyl chloride and its copolymers cold-resistant for organic synthesis, ion selective electrode additives, solvents, insecticides, plasticizers , Gas chromatography stationary liquid (maximum use temperature 100 ℃, solvent is acetone, benzene, dichloromethane, ethanol), selective retention and separation of aromatic compounds, unsaturated compounds, Konpoze terpèn ak divès kalite konpoze oksijèn ki gen (alkòl, aldeid, kèton, èste, elatriye).
