Katundu:
1. Madzi oyera kapena achikasu pang'ono owoneka bwino okhala ndi kununkhira konunkhira.Zosungunuka m'madzi;ethanol;ether ndi chloroform, ndi zina zotero, zosakhazikika, zowonongeka pamene zimagwirizana ndi alkali kapena zosungunula pa kupanikizika kwa mlengalenga.Ndiwosakhazikika, amawola akamalumikizana ndi alkali kapena osungunula pamphamvu ya mumlengalenga.
2.Chinthucho ndi poizoni wochepa, kumeza mankhwala ndikoletsedwa, wogwiritsa ntchito ayenera kuvala zida zotetezera.
3.Chemical properties: Mowa wa Diacetone uli ndi carbonyl ndi hydroxyl mu molekyulu, yokhala ndi mankhwala a ketone ndi mowa wapamwamba.Kuwola kumachitika pamene watenthedwa kufika 130 ° C kapena pamwamba ndi alkali, kupanga mamolekyu awiri a acetone.Ikatenthedwa ndi sulfuric acid kapena kufufuza kuchuluka kwa ayodini, imataya madzi ndikupanga isopropylidene acetone.Kuyanjana ndi sodium hypobromite kumapanga 2-hydroxyisovaleric acid.Catalytic hydrogenation imapanga 2-methyl-2,4-pentanediol.
4.Chida ichi chimakwiyitsa maso, khungu ndi mucous nembanemba zam'mimba.Amalowa m'thupi kudzera m'njira zopuma komanso zam'mimba, zomwe zimakhudza dongosolo lamanjenje ndikuwononga chiwindi ndi m'mimba.Kukoka mpweya wambiri wa nthunzi kumatha kupanga edema ya m'mapapo komanso ngakhale chikomokere.Kuwonekera kwa nthawi yayitali kungayambitse dermatitis.
5. Amapezeka mu fodya wophika, fodya wa nthiti zoyera, fodya wa spice, ndi utsi wa fodya.
Ntchito Yogulitsa:
1.Diacetone mowa ukhoza kugwiritsidwa ntchito ngati zitsulo zotsukira, zosungira matabwa, zosungiramo filimu yojambula zithunzi ndi mankhwala osokoneza bongo, antifreeze, zosungunulira zamadzimadzi amadzimadzi, zowonjezera ndi fiber finishing agent.
2.Diacetone mowa chimagwiritsidwa ntchito monga zosungunulira electrostatic kupopera utoto, celluloid, nitrocellulose, mafuta, mafuta, sera ndi utomoni.Mowa wa Diacetone ndi chinthu chosungunulira kwambiri cha organic.The mamasukidwe akayendedwe ndi otsika ndi zotsatira za kutentha pa mamasukidwe akayendedwe ndi yaing'ono.Amagwiritsidwa ntchito ngati zosungunulira ndi utoto wopaka utoto wa utoto wa cellulose ester, inki yosindikiza, utoto wopangira utomoni etc.
3.Amagwiritsidwa ntchito kwambiri ngati zosungunulira za resins, electrostatic spray paints, celluloid, nitro fibers, mafuta, mafuta ndi sera.Amagwiritsidwanso ntchito ngati zotsukira zitsulo, zosungira matabwa, zosungiramo filimu ndi mankhwala, antifreeze, hydraulic oil solvent, extractant ndi fiber finishing agent.Ndi mtundu wa organic synthesis intermediates.
4.Zodzikongoletsera zosungunulira, zomwe zimagwiritsidwa ntchito makamaka ngati msomali wa misomali ndi zodzoladzola zina zazitsulo zotentha kwambiri.Kawirikawiri amapangidwa ndi otsika otentha mfundo solvents ndi sing'anga-kuwira mfundo solvents mu zosungunulira wosanganiza, kuti apeze yoyenera evaporation mlingo ndi mamasukidwe akayendedwe.
Zolemba Zosungira:
1.Sungani m'nyumba yosungiramo zoziziritsa komanso mpweya wabwino.
2. Khalani kutali ndi moto ndi gwero la kutentha, peŵani kuwala kwa dzuwa.
3.Sungani chidebe chosindikizidwa.
4.Sizowononga zitsulo, ndipo zimatha kusungidwa muzitsulo, zitsulo zofewa kapena aluminiyamu, koma zimakhala ndi mphamvu zowonongeka pamitundu yambiri ya mapulasitiki.
5.Kusunga ndi kunyamula paokha kuchokera ku ma oxidizing agents ndi ma acid.
6.Chidebe chachitsulo kapena botolo lagalasi ladzaza ndi zinthu zamatabwa zamatabwa.
