Khoom Properties:
1.Colorless volatile thiab flammable kua, me ntsis aromatic.Acetone yog miscible nrog dej, ethanol, polyol, ester, ether, ketone, hydrocarbons, halogenated hydrocarbons thiab lwm yam polar thiab non-polar solvents.Ntxiv rau ob peb cov roj xws li xibtes roj, yuav luag tag nrho cov rog thiab roj tuaj yeem yaj.Thiab nws tuaj yeem yaj cellulose, polymethacrylic acid, phenolic, polyester thiab ntau lwm yam resins.Nws muaj peev xwm yaj tsis zoo rau epoxy resin, thiab tsis yooj yim rau yaj polyethylene, furan resin, polyvinylidene chloride thiab lwm yam resins.Nws yog ib qho nyuaj rau dissolve wormwood, roj hmab, asphalt thiab paraffin.Cov khoom no muaj tshuaj lom me ntsis, yog tias qhov vapor concentration tsis paub lossis dhau qhov kev txwv tsis pub dhau, lub tshuab ua pa tsim nyog yuav tsum tau hnav.Tsis ruaj tsis khov rau hnub ci, acids thiab bases.Tsawg kub taw tes thiab volatile.
2.Flammable tshuaj lom nrog nruab nrab toxicity.Cov tshuaj lom me me ua rau muaj kev cuam tshuam rau lub qhov muag thiab cov mucous daim nyias nyias ntawm cov kab mob ua pa sab saud, thiab kev lom lom hnyav muaj cov tsos mob xws li fainting, convulsions, thiab cov tsos ntawm cov protein thiab cov qe ntshav liab hauv cov zis.Thaum muaj kab mob lom tshwm sim hauv tib neeg lub cev, tawm hauv qhov chaw tam sim ntawd, ua pa tsw qab, thiab xa cov mob hnyav mus rau tsev kho mob kom cawm.
3.Acetone belongs rau qeb toxicity tsawg, zoo ib yam li ethanol.Nws feem ntau muaj tshuaj loog rau hauv nruab nrab lub paj hlwb, nqus pa ntawm vapor tuaj yeem ua rau mob taub hau, qhov muag tsis pom kev, ntuav thiab lwm yam tsos mob, qhov txwv tsis pub muaj huab cua yog 3.80mg / m3.Kev sib cuag nrog mucous daim nyias nyias ntawm qhov muag, qhov ntswg thiab tus nplaig tuaj yeem ua rau mob.Thaum qhov concentration ntawm vapor yog 9488mg / m3, 60 feeb tom qab, nws yuav nthuav tawm cov tsos mob lom xws li mob taub hau, khaus ntawm cov hlab ntsws thiab tsis nco qab.Olfactory threshold concentration 1.2 ~ 2.44mg / m3.TJ36-79 qhia tias qhov siab tshaj plaws tso cai nyob rau hauv huab cua ntawm rhiav yog 360mg / m3.
4.Stability: ruaj khov
5. Cov tshuaj txwv tsis pub:Scov oxidants,muaj zog txo cov neeg ua haujlwm, hauv paus
6.Polymerisation txaus ntshai:Tsis yog polymerisation
Khoom siv:
1.Acetone yog ib tug neeg sawv cev qis-boiling point, ceev-drying polar hnyav.Ntxiv nrog rau kev siv los ua cov kuab tshuaj rau cov xim, cov kua roj vanish, cov tshuaj tsuag nitro, thiab lwm yam, nws kuj yog siv los ua cov kuab tshuaj thiab xim stripper hauv kev tsim cov cellulose, cellulose acetate, thiab cov duab thaij duab.Acetone tuaj yeem tshem tawm ntau cov vitamins thiab tshuaj hormones thiab roj av dewaxing.Acetone kuj tseem yog cov khoom siv tseem ceeb rau kev tsim cov acetic anhydride, methyl methacrylate, bisphenol A, isopropylidene acetone, methyl isobutyl ketone, hexylene glycol, chloroform, iodoform, epoxy resins, vitamin C thiab lwm yam.Thiab siv los ua extractant, diluent thiab lwm yam.
