1. Nws yog insoluble nyob rau hauv dej ntawm chav tsev kub, soluble nyob rau hauv feem ntau organic solvents thiab hydrocarbons, thiab muaj zoo compatibility nrog rau feem ntau industrial resins.Dimethyl phthalate yog combustible.Thaum nws ntes hluav taws, siv dej, ua npuas ncauj extinguishing agent, carbon dioxide, hmoov extinguishing tus neeg sawv cev los tua hluav taws.
2. Cov khoom siv tshuaj lom neeg: Nws ruaj khov rau huab cua thiab cua sov, thiab tsis decompose thaum rhuab rau 50 teev nyob ze ntawm lub boiling point.Thaum lub vapor ntawm dimethyl phthalate dhau los ntawm 450 ° C cua sov rauv ntawm tus nqi ntawm 0.4g / min, tsuas yog me me ntawm decomposition tshwm sim.Cov khoom yog 4.6% dej, 28.2% phthalic anhydride, thiab 51% cov khoom nruab nrab.Tus so yog formaldehyde.Nyob rau tib lub sijhawm, 36% ntawm 608 ° C, 97% ntawm 805 ° C, thiab 100% ntawm 1000 ° C muaj pyrolysis.
3. Thaum dimethyl phthalate hydrolyzed nyob rau hauv methanol tov ntawm caustic potassium ntawm 30 ° C, 22.4% hauv 1 teev, 35.9% hauv 4 teev, thiab 43.8% hauv 8 teev yog hydrolyzed.
4. Dimethyl phthalate reacts nrog methylmagnesium bromide nyob rau hauv benzene, thiab thaum rhuab ntawm chav tsev kub los yog nyob rau hauv ib da dej, 1,2-bis (α-hydroxyisopropyl) benzene yog tsim.Nws reacts nrog phenyl magnesium bromide los tsim 10,10-diphenylanthrone.
