1. Karekau he wairewa i roto i te wai i te pāmahana rūma, ka whakarewahia 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 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.
