Product Properties:
1.Chemical Properties: Butanone inobatwa nemhando dzakasiyana-siyana nekuda kweboka rayo carbonyl uye hydrogen inoshanda iri pedyo neboka re carbonyl.Condensation inoitika kana ichipisa nehydrochloric acid kana sodium hydroxide kuita 3,4-dimethyl-3-hexen-2-one kana 3-methyl-3-hepten-5-imwe.Kana yakavhenekerwa nechiedza chezuva kwenguva yakareba, ethane, acetic acid uye condensation zvigadzirwa zvinoumbwa.Kana yakasvibiswa ne nitric acid, biacetyl inoumbwa.Kana yakasvibiswa nechromic acid uye mamwe maoxidants akasimba, acetic acid inogadzirwa.Butanone inenge yakagadzikana pakupisa, pamusoro pe500°Ckupisa kwekuputika kugadzira alkenone kana methyl alkenone.Kana yakanyungudutswa nealiphatic kana anonhuwirira aldehydes, inoburitsa yakakwira molecular weight ketones, cyclic compounds, ketones uye resins, etc. Semuenzaniso, kana yakanyungudutswa ne formaldehyde pamberi pe sodium hydroxide, inoburitsa bi-acetyl.Semuenzaniso, condensation ne formaldehyde muhupo hwe sodium hydroxide inotanga kubudisa 2-methyl-1-butanol-3-one uye inopedza mvura kuti ibudise methylisopropenyl ketone.Mushonga uyu unobata resination kana uchinge waiswa kuchiedza chezuva kana ultraviolet chiedza.Condensation ne phenol inoburitsa 2,2-bis(4-hydroxyphenyl)butane.Inopindura nealiphatic esters pamberi peiyo catalyst yekutanga kugadzira β-diketones.Acylation ine anhydride pamberi peiyo acidic catalyst kuumba β-diketone.Kuita nehydrogen cyanide kuumba cyanohydrin.Inopindirana neammonia kuumba ketopiperidine derivatives.Iyo α-hydrogen atomu yebutanone inotsiviwa nyore nyore nema halogens kuti iite akasiyana halogenated ketoni, semuenzaniso, 3-chloro-2-butanone ine chlorine.Kudyidzana ne2,4-dinitrophenylhydrazine inogadzira yero 2,4-dinitrophenylhydrazone (mp 115 ° C).
2.Kugadzikana: Kugadzikana
3.Zvinhu zvinorambidzwa:Smaoxidants akasimba,yakasimba kuderedza vamiririri, mabhesi
4.Polymerization ngozi:Kwete-polymerization
Product Application:
1.Butanone inonyanya kushandiswa seyakagadziriswa, yakadai seyokuzora mafuta dewaxing, indasitiri yepende uye zvakasiyana-siyana zve resin solvents, mafuta emafuta emafuta emuchero uye nzira yekuchenesa zeotropic distillation.
2.Butanone zvakare kugadzirira kwemishonga, dhayi, detergents, zvinonhuwira, antioxidants uye zvimwe zvinogadzirisa zviri pakati, synthetic anti-desiccant agent methyl ethyl ketone oxime, polymerization catalyst methyl ethyl ketone peroxide, etching inhibitor methyl pentynol, indasitiri yemagetsi sephotolithography yemasekete akabatanidzwa mushure memugadziri.
3.Inoshandiswa se detergent, lubricant dewaxing agent, vulcanisation accelerator uye reaction intermediates.
4.Used in organic synthesis.Inoshandiswa se chromatographic yekuongorora yakajairwa zvinhu uye solvent.
5.Inoshandiswa muindasitiri yemagetsi, inowanzoshandiswa sekuchenesa uye degreasing agent.
6.Kuwedzera pakushandiswa zvakanyanya mukunatsa mafuta, machira, anobatsira, adhesives, dhayi, mishonga yemishonga uye zvemagetsi kuchenesa, nezvimwewo, inonyanya kushandiswa sechinhu chinonyungudutsa chenitrocellulose, vinyl resin, acrylic resin uye mamwe masisitimu ekugadzira.Zvakanakira kunyungudika kwakasimba uye kuderera kuderera pane acetone.Mukubviswa kwemafuta emiriwo, kunatsa maitiro ezeotropic distillation uye kugadzirira kwezvinonhuwira, antioxidants uye mamwe maapplication.
7.Iyo zvakare chinhu chakasvibirira che organic synthesis uye chinogona kushandiswa sechinhu chinonyungudutsa.Muindasitiri yekuchenesa oiri yekuzora mafuta dewaxing agent, ichishandiswa mukurapa, pendi, dhayi, detergents, zvinonhuwira uye zvemagetsi uye mamwe maindasitiri.Solvent for liquid inki.Inoshandiswa muzvizoro zvekugadzirwa kwembambo yembambo, sechinhu chakaderera-chinopisa chinonyungudutsa, chinogona kuderedza viscosity yepikiri yembambo, kuomesa-kuoma.
8.Inoshandiswa se solvent, dewaxing agent, inoshandiswawo mu organic synthesis, uye sezvinhu zvakasvibiswa zvekugadzira zvinonhuwira nemishonga.
Chigadzirwa Chekuchengetedza Notes:
1.Chengetedza munzvimbo inotonhorera, ine mhepo yekuchengetera mhepo.
2.Gara kure nemoto uye kupisa sosi.
3.Kupisa kwekuchengetedza hakufaniri kudarika37°C.
4.Chengetedza mudziyo wakavharwa.
5.Inofanira kuchengetwa zvakasiyana kubva kune oxidising agents,kuderedza mishonga uye alkalis,uye haifaniri kumbosanganiswa.
6.Shandisa kuputika-kuvhenekera uye zvivako zvemhepo.
7.Kurambidza kushandiswa kwemichina yemagetsi uye zvishandiso zviri nyore kugadzira mazhenje.
8.Nzvimbo yekuchengetera inofanirwa kuve yakashongedzerwa nekudonha kwechimbichimbi michina yekurapa uye yakakodzera pekugara zvinhu.
