    Isicelo

    I-1.Ingasetshenziswa njenge-solvent ye-cellulose esters, ama-synthetic resins nama-rubber, kanye nezinsiza zezintambo ze-polyester.

    2.Ibuye isetshenziselwe ukulungisa ukunambitheka kokudla. Isetshenziselwa ukwenza i-strawberry, uphayinaphu, i-cherry, i-rum nezinye i-essence.

    Impahla

    Ixubene ne-ether, i-methanol ne-ether, kodwa ayincibiliki emanzini ne-glycerin.

    Isitoreji

    Imithetho yesitoreji Gcina endaweni epholile, nengena umoya. Gcina kude nomlilo nemithombo yokushisa. Izinga lokushisa lokugcina aweqi ku-35℃, kanti umswakama ohlobene aweqi ama-85%. Gcina isitsha sivalwe ngokuqinile. Kufanele igcinwe ngokuhlukana nama-oxidants, ama-alkali, namakhemikhali adliwayo, futhi igweme ukugcinwa okuxubile. Ifakwe izinhlobonhlobo ezifanele kanye nenani lamathuluzi omlilo. Indawo yokugcina impahla kufanele ifakwe izinto zokwelashwa eziphuthumayo ezivuzayo kanye nezinto ezifanele zokugcina.

    Ukuzinza

    1. Izici zamakhemikhali: I-methyl benzoate izinzile uma kuqhathaniswa, kodwa i-hydrolyzed ukuze ikhiqize i-benzoic acid ne-methanol lapho ishiswa lapho kukhona i-caustic alkali. Alukho ushintsho lapho kushisa ku-tube evaliwe ku-380-400 ° C amahora angu-8. Uma i-pyrolyzed kwi-hot metal mesh, i-benzene, i-biphenyl, i-methyl phenyl benzoate, njll. iyakhiwa. I-Hydrogenation ku-10MPa kanye no-350°C ikhiqiza i-toluene. I-Methyl benzoate ibhekana nokusabela kwe-transesterification notshwala obuyinhloko lapho kukhona i-alkali metal ethanolate. Isibonelo, i-94% yokusabela nge-ethanol ekamelweni lokushisa iba i-ethyl benzoate; I-84% yokusabela nge-propanol iba yi-propyl benzoate. Akukho ukusabela kwe-transesterification nge-isopropanol. I-Benzyl alcohol ester ne-ethylene glycol zisebenzisa i-chloroform njenge-solvent, futhi uma inani elincane le-potassium carbonate lengezwa ku-reflux, kutholakala i-ethylene glycol benzoate kanye nenani elincane le-ethylene glycol benzhydrol ester. I-Methyl benzoate ne-glycerin zisebenzisa i-pyridine njengesixazululi. Lapho kushisa phambi kwe-sodium methoxide, i-transesterification ingenziwa futhi ukuze kutholwe i-glycerin benzoate.

    2. I-Methyl benzyl alcohol ixutshwa nge-nitric acid (ukuminyana okuhlobene 1.517) kumazinga okushisa asekamelweni ukuze kutholwe i-methyl 3-nitrobenzoate ne-methyl 4-nitrobenzoate ngesilinganiso esingu-2:1. Isebenzisa i-thorium oxide njenge-catalyst, ihlangana ne-ammonia ku-450-480°C ukukhiqiza i-benzonitrile. Shisisa nge-phosphorus pentachloride kuye ku-160-180°C ukuze uthole i-benzoyl chloride.

    3. I-Methyl benzoate yakha inhlanganisela ye-crystalline yamangqamuzana ene-aluminium trichloride ne-tin chloride, futhi yakha inhlanganisela yecrystalline egqagqene ene-phosphoric acid.

    4. Ukuzinza nokuzinza

    5. Izinto ezingahambelani, ama-oxidants aqinile, ama-alkali aqinile

    6. Izingozi ze-Polymerization, akukho polymerization
