    Fa'atatauga

    1. E faʻaaogaina e fai ma solvent mo le gaosia o le methyl-ethyl ketone peroxide, faʻafefete faʻamaʻi faʻamaʻi.

    2. E faʻaaogaina e pei o le plasticizer o le cellulose acetate, faʻafefe namu ma le solvent o le polyfluoroethylene coating.

    3.O le vaeluagalemu o rodenticide diphacin, Tetramine ma chlorratone.

    Meatotino

    O le Dimethyl phthalate e leai se lanu manino o le suau'u suau'u, sina manogi. E fa'afefiloi ma le ethanol, eter, soluble i benzene, acetone ma isi solvents organic, e le mafai ona solu i le vai ma minerale suauu.

    Teuina

    1. Teu i totonu o se faleteuoloa malulu, matutu, mamao ese mai afi, la ma timuga. Aloese mai a'afiaga leaga a'o felauaiga.

    2. Plasticizer faʻatasi ma le malosi faʻafefeteina malosi. Faʻaaogaina e fai ma palasitika mo le paʻu nitrile, vinyl resin, cellulose acetate film, cellophane, varnish ma le paʻu paʻu, ma isi. E mafai foʻi ona faʻaaogaina e avea o se solvent mo le sauniuniga o le methyl ethyl ketone peroxide. O loʻo i ai ni mea e sili ona lelei e fai ai ata, faʻapipiʻi ma vai faʻafefe, ma maualuga le faʻamautuina o le vevela, ae e faigofie ona faʻamalama i le maualalo o le vevela ma e maualuga le volatility. O le mea lea, e masani ona faʻaaogaina faʻatasi ma mea faʻapipiʻi e pei o le diethyl phthalate mo le paʻu paʻu. E mafai ona faʻaleleia le palasitika o le paʻu paʻu pe a faʻaaogaina e fai ma sui, aemaise lava mo le paʻu nitrile ma le paʻu neoprene. E mafai fo'i ona fa'aaogaina e fai ma suau'u fa'ama'i namu ma fa'afefe. E iai sona a'afiaga i iniseti mitimiti toto e pei o namu, lago oneone, culms ma namu. Ole taimi fa'ato'a lelei ole 2 i le 4 itula.

    Maumau

    1. E le mafai ona solu i le vai i le vevela o le potu, soluble i le tele o solvents organic ma hydrocarbons, ma e lelei le fetaui lelei ma le tele o resini alamanuia. Dimethyl phthalate e mu. A mu, fa'aaoga le vai, fa'amafu foam, carbon dioxide, pauta e tineia ai le afi.

    2. O mea tau vaila'au: E mautu i le ea ma le vevela, ma e le pala pe a vevela mo le 50 itula i tafatafa o le mea e faʻafefe ai. Pe a pasia le ausa o le dimethyl phthalate i totonu o se ogaumu faʻavevela 450 ° C i le fua o le 0.4g / min, naʻo sina vaega itiiti o le pala e tupu. O le oloa e 4.6% vai, 28.2% phthalic anhydride, ma 51% mea e le tutusa. O isi mea o le formaldehyde. I lalo o tulaga tutusa, 36% i le 608 ° C, 97% i le 805 ° C, ma le 100% i le 1000 ° C e iai le pyrolysis.

    3. Pe a fa'asusu le dimethyl phthalate i se vaifofo methanol o le potassium caustic i le 30°C, 22.4% i le 1 itula, 35.9% i le 4 itula, ma le 43.8% i le 8 itula e fa'asusu.

    4. O le Dimethyl phthalate e tali atu i le methylmagnesium bromide i le benzene, ma pe a vevela i le vevela o le potu poʻo luga o se vai taele, 1,2-bis(α-hydroxyisopropyl)benzene e fausia. E tali atu i le phenyl magnesium bromide e maua ai le 10,10-diphenylanthrone.
