ʻO Dibutyl phthalate, ʻike ʻia hoʻi ʻo dibutyl phthalate a i ʻole dibutyl phthalate, Pelekania: Dibutylphthalate, he wai ʻaila ʻalohi ʻole waihoʻoluʻu me ka umekaumaha kikoʻī o 1.045 (21°C) a me kahi paila o 340°C, ʻaʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai, akā hiki ke hoʻoheheʻe ʻia i ka wai a me ka maʻalahi. etera, acetone a me benzene, a hiki ke hui pu me ka nui o ka hydrocarbons. ʻO ka dibutyl phthalate (DBP), ka dioctyl phthalate (DOP) a me ka diisobutyl phthalate (DIBP) ʻo ia nā mea plasticizer maʻamau ʻekolu, ʻo ia hoʻi nā 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 ʻala ʻole waihoʻoluʻu me ka ʻala ʻala iki. Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik a me nā hydrocarbons.
Palapala noi
-Hoʻohanaʻia e like me ka plasticizer no ka nitrocellulose, cellulose acetate, polyvinyl chloride, a me nā mea'ē aʻe. He mana hoʻoheheʻe ikaika i nā resins like ʻole.
-Hoʻohana ʻia 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 kona hoʻohana ʻana. ʻO kēia huahana he plasticizer maikaʻi loa o ka nitrocellulose a he ikaika ka gelling.
-Hoʻohana ʻia no nā uhi nitrocellulose, he hopena palupalu maikaʻi loa. ʻO ke kūpaʻa maikaʻi, ke kūpaʻa flex, 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 mea hoʻopili, nā ʻili kūlohelohe, nā ʻīnika paʻi, nā 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 ke kāpili maoli, polystyrene; e hana i ka polyvinyl chloride a me kona copolymers pale anu no ka organic synthesis, ion selective electrode additives, solvents, insecticides, plasticizers , Gas chromatography stationary wai (ka wela hoʻohana kiʻekiʻe 100 ℃, solvent he acetone, benzene, dichloromethane, ethanol), ka hoʻopaʻa ʻana a me ka hoʻokaʻawale ʻana o nā mea hoʻohui ʻole, ka hui pū ʻole a me ka hoʻokaʻawale ʻana. nā mea i loaʻa i ka oxygen (ʻona, aldehydes, ketones, esters, etc.).
