    Kugwiritsa ntchito

    1.Itha kugwiritsidwa ntchito ngati zosungunulira za ma cellulose esters, ma resins opangira ndi ma rubber, ndi othandizira a polyester fibers.

    2.Amagwiritsidwanso ntchito pokonza zokometsera zakudya. Amagwiritsidwa ntchito kupanga sitiroberi, chinanazi, chitumbuwa, ramu ndi zina.

    Katundu

    Ndi miscible ndi ether, methanol ndi ether, koma osasungunuka m'madzi ndi glycerin.

    Kusungirako

    Kusamala posungira Sungani m'nyumba yosungiramo yozizirirapo mpweya wokwanira. Khalani kutali ndi gwero la moto ndi kutentha. Kutentha kosungirako sikudutsa 35 ℃, ndipo chinyezi sichidutsa 85%. Sungani chidebecho chotsekedwa mwamphamvu. Iyenera kusungidwa mosiyana ndi zotulutsa, alkalis, ndi mankhwala odyedwa, ndipo pewani kusungirako kosakanikirana. Okonzeka ndi mitundu yoyenera komanso kuchuluka kwa zida zozimitsa moto. Malo osungiramo zinthu ayenera kukhala ndi zida zowonongeka zowonongeka ndi zipangizo zoyenera zosungirako.

    Kukhazikika

    1. Chemical properties: Methyl benzoate imakhala yokhazikika, koma imapangidwa ndi hydrolyzed kuti ipange benzoic acid ndi methanol ikatenthedwa pamaso pa caustic alkali. Palibe kusintha mukatenthedwa mu chubu losindikizidwa pa 380-400 ° C kwa maola 8. Pamene pyrolyzed pa zitsulo zotentha mauna, benzene, biphenyl, methyl phenyl benzoate, ndi zina zotero. Hydrogenation pa 10MPa ndi 350°C imapanga toluene. Methyl benzoate amakumana ndi transesterification reaction ndi ma alcohols oyambira pamaso pa alkali metal ethanolate. Mwachitsanzo, 94% ya anachita ndi Mowa firiji amakhala ethyl benzoate; 84% ya anachita ndi propanol amakhala propyl benzoate. Palibe kusintha kwa transesterification ndi isopropanol. Benzyl mowa ester ndi ethylene glycol amagwiritsa ntchito chloroform monga zosungunulira, ndipo pamene pang'ono potaziyamu carbonate iwonjezeredwa ku reflux, ethylene glycol benzoate ndi ethylene glycol benzhydrol ester pang'ono amapezeka. Methyl benzoate ndi glycerin amagwiritsa ntchito pyridine ngati zosungunulira. Mukatenthedwa pamaso pa sodium methoxide, transesterification imathanso kuchitidwa kuti mupeze glycerin benzoate.

    2. Methyl benzyl mowa ndi nitrate ndi nitric acid (chibale kachulukidwe 1.517) pa kutentha kutentha kuti apeze methyl 3-nitrobenzoate ndi methyl 4-nitrobenzoate mu chiŵerengero cha 2: 1. Pogwiritsa ntchito thorium oxide monga chothandizira, imakhudzidwa ndi ammonia pa 450-480 ° C kuti ipange benzonitrile. Kutenthetsa ndi phosphorous pentachloride kufika 160-180°C kuti mupeze benzoyl chloride.

    3. Methyl benzoate imapanga crystalline molecular compound ndi aluminium trichloride ndi tini chloride, ndipo imapanga flaky crystalline pawiri ndi phosphoric acid.

    4. Kukhazikika ndi kukhazikika

    5. Zida zosagwirizana, zowonjezera zowonjezera, ma alkali amphamvu

    6. Zowopsa za polymerization, palibe polymerization
