1. Cov khoom siv tshuaj: Methyl benzoate kuj ruaj khov, tab sis nws yog hydrolyzed los tsim benzoic acid thiab methanol thaum rhuab nyob rau hauv lub xub ntiag ntawm caustic alkali. Tsis muaj kev hloov pauv thaum cua sov hauv lub raj kaw ntawm 380-400 ° C rau 8 teev. Thaum pyrolyzed ntawm kub hlau mesh, benzene, biphenyl, methyl phenyl benzoate, thiab lwm yam yog tsim. Hydrogenation ntawm 10MPa thiab 350 ° C tsim cov toluene. Methyl benzoate tau dhau los ua cov tshuaj tiv thaiv transesterification nrog thawj cov cawv hauv lub xub ntiag ntawm alkali hlau ethanolate. Piv txwv li, 94% ntawm cov tshuaj tiv thaiv nrog ethanol ntawm chav tsev kub dhau los ua ethyl benzoate; 84% ntawm cov tshuaj tiv thaiv nrog propanol ua propyl benzoate. Tsis muaj cov tshuaj tiv thaiv transesterification nrog isopropanol. Benzyl cawv ester thiab ethylene glycol siv chloroform ua hnyav, thiab thaum me me ntawm cov poov tshuaj carbonate ntxiv rau reflux, ethylene glycol benzoate thiab ib qho me me ntawm ethylene glycol benzhydrol ester tau txais. Methyl benzoate thiab glycerin siv pyridine ua cov kuab tshuaj. Thaum rhuab nyob rau hauv lub xub ntiag ntawm sodium methoxide, transesterification tuaj yeem ua tau kom tau txais glycerin benzoate.
2. Methyl benzyl cawv yog nitrated nrog nitric acid (tus txheeb ze ntom ntom 1.517) nyob rau hauv chav tsev kub kom tau methyl 3-nitrobenzoate thiab methyl 4-nitrobenzoate nyob rau hauv ib tug ratio ntawm 2: 1. Siv thorium oxide ua ib qho catalyst, nws reacts nrog ammonia ntawm 450-480 ° C los tsim benzonitrile. Kub nrog phosphorus pentachloride rau 160-180 ° C kom tau txais benzoyl chloride.
3. Methyl benzoate ua cov crystalline molecular compound nrog aluminium trichloride thiab tin chloride, thiab tsim cov flaky crystalline compound nrog phosphoric acid.
4. Kev ruaj ntseg thiab ruaj khov
5. Cov ntaub ntawv tsis sib xws, muaj zog oxidants, muaj zog alkalis
6. Polymerization txaus ntshai, tsis muaj polymerization
