O le Dioctyl phthalate o lo'o ta'ua o le dioctyl ester (DOP) - o se mea fa'apipi'i ester organic ma se mea fa'apipi'i masani. O le Dioctyl phthalate o se mea fa'apipi'i fa'apitoa lautele. E masani ona faʻaaogaina i le gaosiga o le polyvinyl chloride resin, ma e mafai foi ona faʻaaogaina i le gaosiga o polymers maualuga e pei ole vailaʻau fibre resin, resin acetic acid, resin ABS, ma paʻu. Vali, vali, dispersants, etc.

Fa'amoemoe lautele DOP: fa'aaoga lautele i palasitika, pa'u, vali, emulsifiers, ma isi alamanuia. PVC fa'apipi'i fa'atasi ma e mafai ona fa'aogaina e gaosia ai pa'u pa'u, ata fa'ato'aga, mea fa'apipi'i, uaea, ma isi.

DOP eletise: I le faaopoopo atu i meatotino uma o le DOP mo le lautele, o loʻo i ai foi mea faʻapipiʻi eletise lelei, e masani ona faʻaaogaina i le gaosiga o uaea ma eletise.

Food grade DOP: e masani ona faʻaaogaina i le gaosiga o meaʻai meaʻai.

Fomaʻi vasega DOP: e masani ona faʻaaogaina mo le gaosiga o vailaʻau faʻafomaʻi ma le soifua maloloina, e pei o mea faʻapitoa faʻafomaʻi ma mea faʻapipiʻi faʻafomaʻi.

DOTP

DOTP plasticizer o le isi ituaiga o plasticizers, o lenei oloa e toetoe lava leai se lanu e maualalo-viscosity vai. Viscosity 63mPa.s (25°C), 5mPa.s (100°C), 410mPa.s (0°C). Mea malulu -48°C. O le mea fa'apuna e 383°C (0.1)MPa.s (0°C). O le mea e fa'amumu ai e 399°C. Igoa faasaienisi: dioctyl terephthalate. E masani lava, matou te taʻua o le DOTP.

I le faʻaopoopoga i le tele o mea faʻapipiʻi faʻaaogaina i mea uaea ma PVC, e mafai foi ona faʻaaogaina le DOTP i le gaosiga o ata paʻu paʻu. E le gata i lea, o loʻo i ai le fetaui lelei ma e mafai foi ona faʻaaogaina e fai ma plasticizer mo acrylonitrile derivatives, polyvinyl butyral, nitrile rubber, nitrocellulose, ma isi.

1. Tulaga eseese o DOP ma DOTP

Pe a faatusatusa i le dioctyl phthalate (DOP) masani ona faʻaaogaina, o le dioctyl terephthalate (DOTP) o loʻo i ai le lelei o le faʻafefe o le vevela, faʻafefe malulu, le faʻafefeteina, anti-extraction, fetuutuunai, ma mea lelei faʻapipiʻi eletise. E lelei tele le tumau, fasimoli vai, ma maualalo le vevela.

2. Fa'aoga eseese ole DOP ma le DOTP

O le Dioctyl phthalate(DOP) ose mea fa'apipi'i fa'apitoa fa'apitoa. E masani ona faʻaaogaina i le gaosiga o le polyvinyl chloride resin. A leai, e mafai foi ona faʻaaogaina i le gaosiga o polymers maualuga e pei ole vailaʻau fibre resin, acetic acid resin, ABS resin, ma paʻu. Vali, vali, dispersants, etc.

I le faʻaopoopoga i le tele o mea faʻapipiʻi faʻaaogaina i mea uaea ma PVC, e mafai foi ona faʻaaogaina le DOTP i le gaosiga o ata paʻu paʻu. E le gata i lea, o le DOTP e sili ona fetaui lelei. E le gata i lea, e mafai foi ona faʻaaogaina le DOTP e fai ma plasticizer mo acrylonitrile derivatives, polyvinyl butyral, nitrile rubber, nitrocellulose, ma isi.
