    Taupānga

    1.Ka taea te whakamahi hei whakarewa mo nga esters cellulose, nga kapia waihanga me nga rapa, me nga awhina mo nga muka polyester.

    2.Ka whakamahia ano hoki mo te whakarite i nga kai reka. Ka whakamahia ki te hanga rōpere, pineapi, here, rama me etahi atu ngako.

    Taonga

    Ka uru ki te ether, methanol me te ether, engari karekau e rewa ki te wai me te glycerin.

    Rokiroki

    Whakatupatotanga Rokiroki Rokiroki i roto i te whare putunga hauhautanga, whai hau. Kia matara atu i te ahi me nga puna wera. Ko te pāmahana rokiroki e kore e neke ake i te 35 ℃, me te haumākū whanaunga e kore e neke atu i te 85%. Kia kati te ipu. Me penapena motuhake mai i nga waiora, nga kawakore, me nga matū kai, me te karo i te rokiroki whakauru. Kua rite ki nga momo momo me te maha o nga taputapu ahi. Ko te waahi rokiroki me whakauru ki nga taputapu maimoatanga ohorere pakaru me nga taonga rokiroki tika.

    Te pumau

    1. Nga mea matū: Methyl benzoate he ahua pumau, engari ka whakamaarama hei whakaputa i te waikawa benzoic me te mewaro ina whakamahana i te aroaro o te kawakore. Karekau he huringa ina whakamahana i roto i te ngongo hiri i te 380-400°C mo te 8 haora. Ka pirolyzed i runga i te mata whakarewa wera, ka hanga te benzene, te biphenyl, te methyl phenyl benzoate, me etahi atu. Ko te whakamaoritanga i te 10MPa me te 350°C ka whakaputa i te toluene. Ko te Methyl benzoate ka tukuna he tauhohenga whakawhiti me nga waipiro tuatahi i te aroaro o te ethanolate whakarewa alkali. Hei tauira, 94% o te tauhohenga me te waiwaro i te pāmahana rūma ka huri hei ethyl benzoate; 84% o te tauhohenga me te propanol ka huri hei propyl benzoate. Karekau he tauhohenga transesterification me te isopropanol. Ko te Benzyl alcohol ester me te ethylene glycol e whakamahi ana i te chloroform hei whakarewa, a ka whakauruhia he iti o te konupora konupora ki te reflux, ka whiwhi te ethylene glycol benzoate me te iti o te ethylene glycol benzhydrol ester. Ko te Methyl benzoate me te glycerin e whakamahi ana i te pyridine hei whakarewa. Ka whakamahana i te aroaro o te konutai methoxide, ka taea hoki te mahi transesterification ki te whiwhi glycerin benzoate.

    2. Ko te waipiro Methyl benzyl ka whakahiato ki te waikawa nitric (kiato whanaunga 1.517) i te pāmahana rūma kia whiwhi ai te methyl 3-nitrobenzoate me te methyl 4-nitrobenzoate i te ōwehenga o te 2:1. Ma te whakamahi i te thorium oxide hei whakakorikori, ka tauhohe ki te haukini i te 450-480°C ki te whakaputa benzonitrile. Whakawerahia te ūkuikui pentachloride ki te 160-180°C kia whiwhi ai i te benzoyl chloride.

    3. Ka hangaia e te Methyl benzoate he pūhui ngota ngota konumohe me te konumohe trichloride me te tine pūhaumāota, me te hanga i te pūhui tioata kirikiri me te waikawa phosphoric.

    4. Te pumau me te pumau

    5. Nga rauemi hotokore, nga waikura kaha, nga kawakore kaha

    6. Nga mea morearea o te polymerization, kaore he polymerization
