Kev piav qhia:
Diethyl phthalate (DEP) yog ib tug tswv cuab ntawm pawg esters ntawm phthalic acid hu ua phthalates, siv thoob plaws ntiaj teb ua cov kuab tshuaj thiab cov yas yas. DEP tuaj yeem ua rau cov yas yooj ywm dua. Nws kuj muaj nyob rau hauv cov tshuaj deodorant, tshuaj tsw qab, emollients thiab cov tshuaj tua kab. Nws tuaj yeem hla kev sib cuag nrog dimethyl phtalate.

Kev Siv
Diethyl phthalate yog Plasticizer rau cellulose ester yas zaj duab xis thiab cov ntawv; hauv cov yas molded; tsim cov varnishes; tshuaj pleev ib ce.
Diethyl phthalate yog ib qho nruab nrab ntawm cov tshuaj tua kab dimouse, murine, thiab chlorpyrone, thiab kuj yog ib qho tseem ceeb ntawm cov kuab tshuaj. Diethyl phthalate yog siv los ua cov yas rau cov yas. Diethyl phthalate yog siv los ua cov tshuaj analytical, cov kua roj chromatography, cov kuab tshuaj rau cellulose thiab esters, cov yas thiab cov roj nplua nyeem. Diethyl phthalate yog siv los ua cov yas, cov kuab tshuaj, cov roj nplua nyeem, cov khoom kho, cov neeg sawv cev ua npuas rau cov xim lossis cov hlau tsis tshua muaj flotation, cov roj chromatography fixative, cawv denaturant, tshuaj tua kab tsuag. Cov khoom no yog sib xyaw nrog cellulose acetate, cellulose acetate butyrate, polyvinyl acetate, nitrocellulose, ethyl cellulose, polymethyl methacrylate, polystyrene, polyvinyl butyral, vinyl chloride-vinyl acetate Feem ntau cov resins xws li copolymers muaj kev sib raug zoo. Nws yog siv los ua cov yas rau cellulose resin, tab sis cov khoom muaj kev hloov pauv siab, uas txwv nws daim ntawv thov dav.
Diethyl phthalate tau siv los ua ib qho hloov pauv rau camphor hauv kev tsim cov celluloid, ua ib qho kuab tshuaj rau cellulose acetate hauv kev tsim cov varnishes thiab dopes, ua ib qho tshuaj tsw qab, thiab rau denaturing ethanol.
