ʻO Diethyl phthalate (DEP) he lālā ia o ka hui o nā esters o ka phthalic acid i ʻike ʻia ʻo phthalates, i hoʻohana nui ʻia ma ke ʻano he solvents a me plasticisers ma ka honua holoʻokoʻa. Hiki i ka DEP ke hoʻonui i ka maʻalahi o nā plastics. Loaʻa pū ia i loko o nā ʻano deodorant, nā mea ʻala, nā emollients a me nā mea pale pepeke. Hiki iā ia ke cross react me dimethyl phtalate.

Hoʻohana
ʻO Diethyl phthalate kahi Plasticizer no nā kiʻiʻoniʻoni a me nā pepa plastik cellulose ester; i nā plastics i hoʻoheheʻe ʻia; hana ʻana i nā varnish; nā mea hoʻonani.
ʻO Diethyl phthalate kahi waena o nā rodenticides dimouse, murine, a me chlorpyrone, a he mea hoʻoheheʻe koʻikoʻi nō hoʻi. Hoʻohana ʻia ʻo Diethyl phthalate ma ke ʻano he plasticizer no nā plastics. Hoʻohana ʻia ʻo Diethyl phthalate ma ke ʻano he reagent analytical, kahi hopena paʻa chromatography gas, kahi mea hoʻoheheʻe no ka cellulose a me nā esters, kahi plasticizer a me kahi lubricant. Hoʻohana ʻia ʻo Diethyl phthalate ma ke ʻano he plasticizer, solvent, lubricant, fixative, foaming agent no ka flotation mine metala kala a kakaʻikahi paha, gas chromatography fixative, alcohol denaturant, spray insecticide. Hoʻohui ʻia kēia huahana me ka cellulose acetate, cellulose acetate butyrate, polyvinyl acetate, nitrocellulose, ethyl cellulose, polymethyl methacrylate, polystyrene, polyvinyl butyral, vinyl chloride-vinyl acetate. ʻO ka hapa nui o nā resins e like me nā copolymers he kūpono maikaʻi. Hoʻohana nui ʻia ia ma ke ʻano he plasticizer no ka cellulose resin, akā he volatility kiʻekiʻe ka huahana, kahi e kaupalena ai i kāna noi ākea.
Ua hoʻohana ʻia ʻo Diethyl phthalate ma ke ʻano he pani no ka camphor i ka hana ʻana o ka celluloid, ma ke ʻano he mea hoʻoheheʻe no ka cellulose acetate i ka hana ʻana o nā varnish a me nā dopes, ma ke ʻano he mea hoʻoheheʻe no nā mea ʻala, a no ka hoʻololi ʻana i ka ethanol.
