Iimpawu zeMveliso:
1.Ulwelo olumhlophe okanye olutyheli kancinane olubonakalayo kunye nencasa enuka kamnandi. Inyibilika emanzini; i-ethanol; I-ether kunye ne-chloroform, njl., engazinzanga, ibolile xa idibana ne-alkali okanye i-distilled kuxinzelelo lwe-atmospheric. Ayizinzile, ibola xa isebenzisana ne-alkali okanye i-distilled kuxinzelelo lwe-atmospheric.
I-2.Imveliso inetyhefu ephantsi, ukugwinya umkhiqizo kunqatshelwe ngokungqongqo, umqhubi kufuneka agqoke izixhobo zokukhusela.
3. Iimpawu zeChemical: I-Diacetone alcohol iqulethe i-carbonyl kunye ne-hydroxyl kwi-molecule, kunye neempawu zeekhemikhali ze-ketone kunye ne-alcohol ephezulu. Ukubola kwenzeka xa kushushu kwi-130 ° C okanye ngaphezulu nge-alkali, ukuvelisa i-acetone ezi-2. Xa ishushu nge-asidi ye-sulfuric okanye i-trace value ye-iodine, ikhupha amanzi ukuze yenze isopropylidene acetone. Ukusebenzisana ne-sodium hypobromite kuvelisa i-2-hydroxyisovaleric acid. I-Catalytic hydrogenation ivelisa i-2-methyl-2,4-pentanediol.
I-4.Le mveliso icaphukisa amehlo, ulusu kunye ne-mucous membranes yendlela yokuphefumula. Ingena emzimbeni ngokuphefumula kunye neendlela zokugaya, ezichaphazela inkqubo ye-nervous kunye nokonakalisa isibindi kunye nesisu. Ukuphefumla umphunga ophezulu kunokwenza i-pulmonary edema kunye ne-coma. Ukubonakaliswa kwexesha elide kunokukhokelela kwi-dermatitis.
5. Ifumaneka kwicuba lokubhaka, icuba elineembambo ezimhlophe, icuba lezinongo, kunye nomsi wecuba.
Isicelo seMveliso:
I-1.I-alcohol ye-Diacetone ingasetyenziselwa njengento yokucoca isinyithi, i-preservative wood, i-preservative yefilimu yezithombe kunye neziyobisi, i-antifreeze, i-solvent ye-hydraulic fluids, i-extractant kunye ne-fiber finishing agent.
I-2.I-alcohol ye-Diacetone isetyenziswa ngokubanzi njenge-solvent ye-electrostatic spray paints, i-celluloid, i-nitrocellulose, i-fats, i-oyile, i-wax kunye ne-resins. I-Diacetone alcohol yindawo ephezulu yokubilisa ye-organic solvent. I-viscosity iphantsi kwaye umphumo wokushisa kwi-viscosity uncinci. Isetyenziswa njenge-solvent kunye ne-stripper yepeyinti yepeyinti ye-cellulose ester, i-inki yokuprinta, ipeyinti ye-synthetic resin njl.
I-3.Isetyenziswe ngokubanzi njenge-solvent ye-resin, iipeyinti zokutshiza i-electrostatic, i-celluloid, i-nitro fibers, amafutha, i-oyile kunye ne-wax. Ikwasetyenziswa njengesicoci sesinyithi, isilondolozi somthi, isigcinakaliso sefilimu yefoto kunye neyeza, i-antifreeze, i-solvent yeoli yehydraulic, i-extractant kunye ne-fiber finishing agent. Kwakhona luhlobo lwe-organic synthesis intermediates.
I-4.I-solvent ye-Cosmetic, esetyenziswa kakhulu njenge-nail polish kunye nezinye izithambiso ze-solvent ephezulu yokubilisa. Ngokuqhelekileyo zenziwe ngee-solvents zamanqaku aphantsi abilayo kunye ne-medium-abilayo i-solvents kwi-solvents exubeneyo, ukuze kufumaneke isantya esifanelekileyo sokunyuka kunye ne-viscosity.
Amanqaku okuGcina iMveliso:
1.Gcina kwindawo epholileyo nengena umoya.
2. Gcina kude nomlilo kunye nomthombo wobushushu, kuphephe ukukhanya kwelanga.
3. Gcina isitya sivaliwe.
I-4.I-non-corrosive to metal, kwaye inokugcinwa kwintsimbi, intsimbi ethambileyo okanye izikhongozeli ze-aluminium, kodwa inempembelelo ephazamisayo kwiindidi ezininzi zeplastiki.
5.Gcina kunye nokuthutha ngokuzimeleyo kwii-agent ze-oxidising kunye ne-acids.
I-6.I-iron ibhakethi okanye ibhotile yeglasi ipakishwe ngempahla yebhokisi yokhuni.
