Whakaahuatanga:
Ko te Diethyl phthalate (DEP) he mema nō te rōpū o ngā esters o te waikawa phthalic e mōhiotia ana ko ngā phthalates, e whakamahia whānuitia ana hei whakarewa me hei kirihou puta noa i te ao. Ka taea e te DEP te whakanui ake i te ngāwari o ngā kirihou. Kei roto hoki i ngā whakatakotoranga deodorant, hinu kakara, whakangawari me ngā ārai pepeke. Ka taea e ia te whakawhiti tauhohe ki te dimethyl phtalate.

Whakamahinga
Ko te Diethyl phthalate he mea hanga kirihou mō ngā kiriata me ngā rau kirihou cellulose ester; i roto i ngā kirihou whakarewa; i te hanga wanihi; i ngā mea whakapaipai.
Ko te Diethyl phthalate he takawaenga o ngā patu kararehe pēnei i te dimouse, te murine, me te chlorpyrone, ā, he whakarewa nui anō hoki. Ka whakamahia te Diethyl phthalate hei whakapūmau kirihou mō ngā kirihou. Ka whakamahia te Diethyl phthalate hei matū tātari, hei otinga tūmau mō te chromatography hau, hei whakarewa mō te cellulose me ngā esters, hei whakapūmau kirihou me te hinu whakahinuhinu. Ka whakamahia te Diethyl phthalate hei whakapūmau kirihou, hei whakarewa, hei whakahinuhinu, hei whakapūmau, hei kaihoko pahuka mō te rere o te konganuku tae, onge rānei, hei whakapūmau chromatography hau, hei whakapūmau waipiro, hei patu pepeke rehu. Ka konatunatua tēnei hua ki te cellulose acetate, te cellulose acetate butyrate, te polyvinyl acetate, te nitrocellulose, te ethyl cellulose, te polymethyl methacrylate, te polystyrene, te polyvinyl butyral, te vinyl chloride-vinyl acetate. He pai te hototahi o te nuinga o ngā kapia pēnei i ngā copolymers. Ko te nuinga o te wā ka whakamahia hei whakapūmau kirihou mō te kapia cellulose, engari he nui te piki me te heke o te hua, e whakawhāiti ana i tōna whānui o te whakamahinga.
Kua whakamahia te diethyl phthalate hei whakakapi mō te camphor i roto i te hanga celluloid, hei whakarewa mō te cellulose acetate i roto i te hanga wanihi me ngā dope, hei matū whakaora mō ngā hinu kakara, me te whakakore i te etanoru.
