ʻO Dibutyl phthalate, ʻike ʻia hoʻi ʻo dibutyl phthalate a i ʻole dibutyl phthalate, Pelekania: Dibutylphthalate, he wai ʻaila ʻalohi kala ʻole me ka umekaumaha kikoʻī o 1.045 (21°C) a me kahi paila o 340°C, hiki ʻole ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i ka wai. liʻiliʻi He haʻahaʻa loa nā waiwai, akā hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka ethanol, ether, acetone a me benzene, a hiki ke hui pū me ka hapa nui o nā hydrocarbons.ʻO ka dibutyl phthalate (DBP), ka dioctyl phthalate (DOP) a me ka diisobutyl phthalate (DIBP) nā mea hoʻopili maʻamau ʻekolu, ʻo ia ka plastics, rubber synthetic a me ka ʻili artificial, etc.Loaʻa ia ma ka esterification thermal o ka phthalic anhydride a me ka n-butanol.
Na Waiwai Kemika
ʻO ka wai ʻaila ʻalani waihoʻoluʻu me ka ʻala ʻala iki.Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik a me nā hydrocarbons.
Palapala noi
-Hoʻohana ʻia e like me ka plasticizer no ka nitrocellulose, cellulose acetate, polyvinyl chloride, etc. ʻO kēia huahana he plasticizer.He mana hoʻoheheʻe ikaika i nā resins like ʻole.
-Hoʻohana no ka hana PVC, hiki iā ia ke hāʻawi i ka palupalu maikaʻi i nā huahana.Ma muli o kona ʻano haʻahaʻa a maikaʻi hoʻi ka hana, hoʻohana nui ʻia ia, aneane like me DOP.Eia nō naʻe, ʻoi aku ka nui o ka volatility a me ka ʻili wai, no laila ʻilihune ka lōʻihi o ka huahana, a pono e kaupalena ʻia ka hoʻohana ʻana.ʻO kēia huahana he plasticizer maikaʻi loa o ka nitrocellulose a he ikaika ka gelling ikaika.
-Hoʻohana ʻia no nā uhi nitrocellulose, he hopena palupalu maikaʻi loa.ʻO ke kūpaʻa maikaʻi loa, ke kūpaʻa flex, ka adhesion a me ka pale wai.Eia kekahi, hiki ke hoʻohana ʻia ka huahana ma ke ʻano he plasticizer no ka polyvinyl acetate, alkyd resin, ethyl cellulose a me neoprene, a hiki ke hoʻohana ʻia i ka hana ʻana i nā pena, nā adhesives, nā ʻili artificial, nā inika paʻi, ke aniani palekana, celluloid, dyes, pesticides. , nā mea hoʻoheheʻe ʻala, nā lubricants lole, etc.
- Ma keʻano he plasticizer no ka cellulose ester, ka paʻakai a me ka'ōpala maoli, polystyrene;e hana i ka polyvinyl chloride a me kona mau copolymers pale anu no ka organik synthesis, ion selective electrode additives, solvents, insecticides, plasticizers, Gas chromatography stationary wai (ka wela hoʻohana kiʻekiʻe 100 ℃, solvent he acetone, benzene, dichloromethane, ethanol), koho paʻa a ka hoʻokaʻawale ʻana o nā pūhui ʻala, nā pūhui unsaturated, nā pūhui terpene a me nā ʻano mea i loaʻa i ka oxygen (ʻona, aldehydes, ketones, esters, etc.).
