    Isicelo

    I-1.Ingasetyenziselwa njenge-solvent ye-cellulose esters, i-synthetic resins kunye ne-rubbers, kunye ne-axiliaries ye-polyester fibers.

    2.Ikwasetyenziselwa ukulungisa incasa yokutya. Isetyenziselwa ukwenza iqunube, ipayinapile, icherry, irum kunye nezinye iiessence.

    Ipropati

    Ixubene ne-ether, i-methanol kunye ne-ether, kodwa ayinyibiliki emanzini kunye ne-glycerin.

    Ugcino

    Izilumkiso zokugcina Gcina kwindawo epholileyo, nengena umoya. Zigcine kude nomlilo kunye nemithombo yobushushu. Ubushushu bokugcina abukho ngaphezu kwe-35℃, kwaye ukufuma okuhambelanayo akudluli kwi-85%. Gcina isitya sivaliwe ngokuqinileyo. Kufuneka igcinwe ngokwahlukileyo kwi-oxidants, alkalis, kunye neekhemikhali ezidliwayo, kwaye ugweme ukugcinwa okuxubileyo. Ixhotyiswe ngeentlobo ezifanelekileyo kunye nobuninzi bezixhobo zomlilo. Indawo yokugcina kufuneka ixhotyiswe ngokuvuza kwezixhobo zonyango olungxamisekileyo kunye nezixhobo ezifanelekileyo zokugcina.

    Uzinzo

    1. Iimpawu zeMichiza: I-Methyl benzoate izinzile, kodwa i-hydrolyzed ukuvelisa i-benzoic acid kunye ne-methanol xa ishushu phambi kwe-alkali ye-caustic. Akukho tshintsho xa ushushu kwi-tube evaliweyo kwi-380-400 ° C kwiiyure ze-8. Xa i-pyrolyzed kumnatha wentsimbi eshushu, ibenzene, i-biphenyl, i-methyl phenyl benzoate, njl. njl. I-Hydrogenation kwi-10MPa kunye ne-350 °C yenza i-toluene. I-Methyl benzoate ifumana i-transesterification reaction kunye nee-alcohol eziphambili kubukho be-alkali yesinyithi ethanolate. Ngokomzekelo, i-94% yokusabela nge-ethanol kwiqondo lokushisa legumbi iba yi-ethyl benzoate; I-84% yokusabela ngepropanol iba yipropyl benzoate. Akukho mpendulo ye-transesterification kunye ne-isopropanol. I-Benzyl alcohol ester kunye ne-ethylene glycol isebenzisa i-chloroform njenge-solvent, kwaye xa inani elincinci le-potassium carbonate lifakwe kwi-reflux, i-ethylene glycol benzoate kunye nenani elincinci le-ethylene glycol benzhydrol ester lifunyenwe. IMethyl benzoate kunye neglycerin zisebenzisa ipyridine njengesinyibilikisi. Xa kushushu phambi kwe-sodium methoxide, i-transesterification inokuqhutyelwa kwakhona ukufumana i-glycerin benzoate.

    2. I-Methyl benzyl alcohol i-nitrate nge-nitric acid (i-1.517 ehambelanayo) kwiqondo lokushisa lokushisa ukuze ifumane i-methyl 3-nitrobenzoate kunye ne-methyl 4-nitrobenzoate kwisilinganiselo se-2: 1. Ukusebenzisa i-thorium oxide njenge-catalyst, isabela nge-ammonia kwi-450-480 ° C ukuvelisa i-benzonitrile. Fudumeza nge-phosphorus pentachloride ukuya kwi-160-180 ° C ukuze ufumane i-benzoyl chloride.

    3. I-Methyl benzoate yenza i-crystalline molecular compound kunye ne-aluminium trichloride kunye ne-tin chloride, kwaye yenza i-flaky crystalline compound kunye ne-phosphoric acid.

    4. Ukuzinza kunye nokuzinza

    5. Izinto ezingahambelaniyo, ii-oxidants ezinamandla, ii-alkali ezinamandla

    6. Iingozi zePolymerization, akukho polymerization
