    Kugwiritsa ntchito

    1. Amagwiritsidwa ntchito ngati zosungunulira popanga methyl-ethyl ketone peroxide, flurocontaining anticorrosive zokutira.

    2.Amagwiritsidwa ntchito ngati plasticizer ya cellulose acetate, mankhwala oletsa udzudzu ndi zosungunulira za polyfluoroethylene zokutira.

    3.Ndi gawo lapakati la rodenticide diphacin, Tetramine ndi chlorratone.

    Katundu

    Dimethyl phthalate ndi madzi amafuta osawoneka bwino, onunkhira pang'ono. Ndi miscible ndi Mowa, etha, sungunuka benzene, acetone ndi zina zosungunulira organic, insoluble m'madzi ndi mchere mafuta.

    Kusungirako

    1. Sungani mosungiramo mozizira, mouma, kutali ndi moto, dzuwa ndi mvula. Pewani zachiwawa panthawi ya mayendedwe.

    2. Pulasitiki yokhala ndi mphamvu yosungunuka kwambiri. Ntchito monga plasticizer kwa nitrile mphira, vinilu utomoni, mapadi acetate filimu, cellophane, varnish ndi akamaumba ufa, etc. Angagwiritsidwenso ntchito monga zosungunulira pokonza methyl ethyl ketone peroxide. Ili ndi zinthu zabwino kwambiri zopanga filimu, zomatira ndi kukana madzi, komanso kukhazikika kwamafuta ambiri, koma ndizosavuta kuzimitsa kutentha pang'ono komanso kusinthasintha kwakukulu. Chifukwa chake, nthawi zambiri amagwiritsidwa ntchito kuphatikiza ndi mapulasitiki monga diethyl phthalate pakupanga mphira. Ikhoza kupititsa patsogolo pulasitiki ya mphira wa rabara pamene imagwiritsidwa ntchito ngati wothandizira, makamaka oyenera mphira wa nitrile ndi rabala wa neoprene. Itha kugwiritsidwanso ntchito ngati mafuta oletsa udzudzu komanso othamangitsa. Zimakhala ndi zotsatira zowononga tizilombo toyamwa magazi monga udzudzu, mchenga, culms ndi ntchentche. Nthawi yabwino yobweza ndi 2 mpaka 4 hours.

    Kukhazikika

    1. Sasungunuke m'madzi kutentha kwa firiji, kusungunuka m'madzi ambiri osungunulira ndi ma hydrocarbons, ndipo imagwirizana bwino ndi utomoni wambiri wamakampani. Dimethyl phthalate imatha kuyaka. Ikagwira moto, gwiritsani ntchito madzi, chozimitsa chithovu, mpweya woipa, wozimitsa ufa kuti uzimitse moto.

    2. Mankhwala amtundu: Ndiwokhazikika ku mpweya ndi kutentha, ndipo samawola akatenthedwa kwa maola 50 pafupi ndi malo otentha. Pamene mpweya wa dimethyl phthalate umadutsa mu ng'anjo yotentha ya 450 ° C pa mlingo wa 0.4g / min, kuwonongeka kochepa kokha kumachitika. Mankhwalawa ndi 4.6% madzi, 28.2% phthalic anhydride, ndi 51% osalowerera ndale. Zina zonse ndi formaldehyde. Pansi pazimenezi, 36% pa 608 ° C, 97% pa 805 ° C, ndi 100% pa 1000 ° C ali ndi pyrolysis.

    3. Pamene dimethyl phthalate ndi hydrolyzed mu njira ya methanol ya caustic potassium pa 30 ° C, 22.4% mu 1 ora, 35.9% mu maola 4, ndi 43.8% mu maola 8 ndi hydrolyzed.

    4. Dimethyl phthalate imakhudzidwa ndi methylmagnesium bromide mu benzene, ndipo ikatenthedwa kutentha kapena pamadzi osamba, 1,2-bis(α-hydroxyisopropyl) benzene imapangidwa. Imachita ndi phenyl magnesium bromide kupanga 10,10-diphenylathrone.
