    Taupānga

    1.Ka whakamahia hei whakarewa mo te whakaputa methyl-ethyl ketone peroxide, flurocontaining anticorrosive coatings.

    2.Ka whakamahia hei plasticizer o te acetate cellulose, te mokowhiti me te whakarewa o te paninga polyfluoroethylene.

    3.Ko te takawaenga o rodenticide diphacin, Tetramine me te chlorratone.

    Taonga

    Ko te Dimethyl phthalate he wai hinuhinu marama kore tae, paku kakara. He micible ki te waihano, ether, wairewa i roto i te benzene, acetone me etahi atu whakarewa pararopi, kare e rewa i te wai me te hinu kohuke.

    Rokiroki

    1. Rokiroki i roto i te whare putunga hauhautanga, maroke, kia matara atu i te ahi, te ra me te ua. A ape i te pa kaha i te wa e kawe ana.

    2. Plasticizer me te kaha te whakakore. Ka whakamahia hei kirihou mo te rapa nitrile, te vinyl resin, te kiriata cellulose acetate, te cellophane, te varnish me te paura whakarewa, me etahi atu ka taea hoki te whakamahi hei whakarewa mo te whakarite i te methyl ethyl ketone peroxide. He pai rawa nga ahuatanga o te hanga kiriata, te piri me te aukati wai, me te mau tonu o te waiariki, engari he ngawari ki te whakamaarama i te iti o te pāmahana me te nui o te whitiwhitinga. Na reira, he maha nga wa e whakamahia ana ki te whakakotahi me nga kaiparapara penei i te diethyl phthalate mo te whakakikorua rapa. Ka taea e ia te whakapai ake i te kirihou o te puhui rapa ina whakamahia ana hei kaihoko, ina koa mo te rapa nitrile me te rapa neoprene. Ka taea hoki te whakamahi hei hinu mo te namu me te whakakore. He awe ki runga i nga pepeke ngote toto penei i te waeroa, te namu, te kumara me te kutu. Ko te 2 ki te 4 haora te roa o te peera.

    Te pumau

    1. He kore e whakarewahia i roto i te wai i te pāmahana rūma, he whakarewa i roto i te nuinga o nga whakarewa pararopi me te waiwaro, a he pai te hototahi ki te nuinga o nga kapia ahumahi. Ko te Dimethyl phthalate he mura. Ina ka ka ahi, whakamahia te wai, te patu pahuka, te waro hauhaa, te paura tinei hei tinei i te ahi.

    2. Nga ahuatanga matū: He pumau ki te hau me te wera, karekau e pirau ina whakamahana mo te 50 haora e tata ana ki te waahi kohua. Ina tukuna te kohu o te dimethyl phthalate i roto i te oumu whakamahana 450°C i te tere o te 0.4g/min, he iti noa te pirau ka puta. Ko te hua ko te 4.6% te wai, te 28.2% te phthalic anhydride, me te 51% nga matū kūpapa. Ko te toenga he formaldehyde. I raro i nga tikanga ano, 36% i te 608 ° C, 97% i te 805 ° C, me te 100% i te 1000 ° C he pyrolysis.

    3. Ina whakamarohia te dimethyl phthalate ki te wairewa methanol o te pāhare pāporo caustic i te 30°C, 22.4% i roto i te 1 haora, 35.9% i roto i te 4 haora, me te 43.8% i roto i te 8 haora ka hauwai.

    4. Ka tauhohe te Dimethyl phthalate ki te methylmagnesium bromide i roto i te benzene, a ka whakamahana i te pāmahana rūma, i runga ranei i te pati wai, ka puta te 1,2-bis(α-hydroxyisopropyl)benzene. Ka tauhohe ki te phenyl magnesium bromide ki te whakaputa 10,10-diphenylanthrone.
