    Codsiga

    1.Waxa loo isticmaali karaa sida dareere loogu talagalay esters cellulose, resins synthetic iyo caag, iyo caawiye ee fiilooyinka polyesterka.

    2.Waxa kale oo loo isticmaalaa diyaarinta dhadhanka cuntada. Waxaa loo isticmaalaa in lagu sameeyo strawberry, cananaaska, cherry, rum iyo nuxur kale.

    Hanti

    Waxay la mid tahay ether, methanol iyo ether, laakiin aan lagu milmin biyaha iyo glycerin.

    Kaydinta

    Taxadarrada kaydinta Ku kaydi bakhaar qabow oo hawo leh. Ka fogow dabka iyo ilaha kulaylka. Heerkulka kaydinta kama badna 35 ℃, iyo qoyaanka qaraabada ah kama badna 85%. Weelka si adag u xidh. Waa in si gooni ah loo kaydiyaa oksaydhiyeyaasha, alkalis, iyo kiimikooyinka la cuni karo, kana fogow kaydinta isku dhafan. Lagu qalabeeyay noocyada ku habboon iyo tirada qalabka dabka. Goobta wax lagu kaydiyo waa in lagu qalabeeyaa qalab daawaynta degdega ah ee daadsan iyo agab kayd oo ku haboon.

    Xasilooni

    1. Waxyaabaha kiimikaad: Methyl benzoate waa mid xasiloon, laakiin waxaa lagu shubaa si ay u dhaliso benzoic acid iyo methanol marka la kululeeyo iyadoo ay joogaan caustic alkali. Ma jiro wax isbeddel ah marka lagu kululeeyo tuubo xiran 380-400 ° C ilaa 8 saacadood. Marka pyrolyzed on mesh birta kulul, benzene, biphenyl, methyl phenyl benzoate, iwm ayaa la sameeyaa. Hydrogenation at 10MPa iyo 350°C waxay abuurtaa toluene. Methyl benzoate waxay martaa falcelinta transesterification oo leh alkolada aasaasiga ah iyadoo ay jirto ethanlate birta alkali. Tusaale ahaan, 94% falcelinta ethanol ee heerkulka qolka waxay noqotaa ethyl benzoate; 84% falcelinta propanol waxay noqotaa propyl benzoate. Ma jiro falcelin transesterification leh isopropanol. Benzyl alkohol ester iyo ethylene glycol waxay isticmaalaan chloroform sida dareere ah, iyo marka qadar yar oo potassium carbonate ah lagu daro reflux, ethylene glycol benzoate iyo qadar yar oo ah ethylene glycol benzhydrol ester ayaa la helaa. Methyl benzoate iyo glycerin waxay isticmaalaan pyridine sida dareere ahaan. Marka la kululeeyo joogitaanka sodium methoxide, transesterification ayaa sidoo kale la samayn karaa si loo helo glycerin benzoate.

    2. Methyl benzyl khamriga waxaa lagu darey nitric acid (cufnaanta qaraabada 1.517) heerkulka qolka si loo helo methyl 3-nitrobenzoate iyo methyl 4-nitrobenzoate ee saamiga 2: 1. Isticmaalka thorium oxide sida kicinta, waxay la falgashaa ammonia 450-480 ° C si ay u soo saarto benzonitrile. Kuleylka fosfooraska pentachloride ilaa 160-180 ° C si aad u hesho benzoyl chloride.

    3. Methyl benzoate waxa ay samaysaa iskudhis molecular crystalline leh aluminium trichloride iyo tin chloride, oo waxa ay samaysaa iskudhis crystalline flaky oo leh phosphoric acid.

    4. Xasilooni iyo xasilooni

    5. Qalab aan ku haboonayn, oksaydhiyeyaasha xooggan, alkalis xooggan

    6. Khataraha polymerization, ma jiro polymerization
