Ibicuruzwa:
1.Imiterere yimiti: Butanone irashobora kwibasirwa nuburyo butandukanye bitewe nitsinda ryayo rya karubone hamwe na hydrogen ikora yegeranye nitsinda rya karubone. Ubucucike bubaho iyo ushyutswe na aside hydrochloric cyangwa hydroxide ya sodium kugirango ube 3,4-dimethyl-3-hexen-2-imwe cyangwa 3-methyl-3-hepten-5-imwe. Iyo ihuye nizuba ryigihe kirekire, etan, acide acike nibicuruzwa bya kondegene. Iyo okiside hamwe na acide ya nitric, habaho biacetyl. Iyo okiside hamwe na acide chromic hamwe nizindi okiside ikomeye, aside irike iba. Butanone irahagaze neza kugirango ubushyuhe, hejuru ya 500°Cgucana amashyuza kubyara alkenone cyangwa methyl alkenone. Iyo ihujwe na alifatique ya alifatique cyangwa aromatique, itanga uburemere buke bwa ketone, ibinyabuzima bya cyclicale, ketone na resin, nibindi. Kurugero, kondegene hamwe na formaldehyde imbere ya hydroxide ya sodium ibanza gutanga 2-methyl-1-butanol-3-imwe hanyuma ikabura umwuma kugirango ikore methylisopropenyl ketone. Uru ruganda ruhura nigihe urumuri rwizuba cyangwa urumuri ultraviolet. Kwiyongera hamwe na fenolike bitanga 2,2-bis (4-hydroxyphenyl) butane. Igisubizo hamwe na alifatique esters imbere yumusemburo wibanze wo gukora β-diketone. Acylation hamwe na anhydride imbere ya catisale acide kugirango ikore β-diketone. Igisubizo hamwe na hydrogen cyanide kugirango ikore cyanohydrine. Igisubizo hamwe na ammonia kugirango ikore ketopiperidine. Atom α-hydrogen atom ya butanone isimburwa byoroshye na halogene kugirango ikore ketone zitandukanye, urugero, 3-chloro-2-butanone hamwe na chlorine. Imikoranire na 2,4-dinitrophenylhydrazine itanga umuhondo 2,4-dinitrophenylhydrazone (mp 115 ° C).
2. Guhagarara: Birahamye
3.Ibintu bibujijwe:Sokiside ya trong,imbaraga zikomeye zo kugabanya, shingiro
4.Ikibazo cya polimerisation:Ntabwo polymerisation
Gusaba ibicuruzwa:
1.Butanone ikoreshwa cyane nkigishishwa, nko gusiga amavuta amavuta yo kwisiga, inganda zisiga amarangi hamwe nudukoko twinshi twa resin, uburyo bwo kuvoma amavuta yimboga hamwe nuburyo bwo gutunganya azeotropique.
2.Butanone kandi ni ugutegura imiti, amarangi, ibikoresho byogajuru, ibirungo, antioxydants hamwe na catalizator zimwe na zimwe ni abahuza, intungamubiri ya anti-desiccant agent methyl ethyl ketone oxime, polymerisation catisale methyl ethyl ketone peroxide, etching inhibitor methyl pentynol, nibindi, muri, inganda za elegitoronike nka fotolitografi yumuzunguruko uhuriweho nyuma yuwitezimbere.
3.Yakoreshejwe nka detergent, lubricant dewaxing agent, yihuta ya volcanisation hamwe nabahuza.
4.Yakoreshejwe muri synthesis. Byakoreshejwe nka chromatografique isesengura ibintu bisanzwe na solvent.
5.Bikoreshwa mubikorwa bya elegitoroniki, bikunze gukoreshwa nkibikoresho byo gusukura no gutesha agaciro.
6. Usibye gukoreshwa cyane mugutunganya amavuta, gutwikira, abafasha, gufatira, amarangi, imiti yimiti nibikoresho bya elegitoronike, nibindi, bikoreshwa cyane nkumuti wa nitrocellulose, vinyl resin, resin ya acrylic nibindi bisigarira bya sintetike. Ibyiza byayo ni imbaraga zikomeye kandi zihindagurika kuruta acetone. Mugukuramo amavuta yimboga, gutunganya uburyo bwo gutobora azeotropique no gutegura ibirungo, antioxydants nibindi bikorwa.
7.Ni kandi ibikoresho fatizo bya synthesis organique kandi birashobora gukoreshwa nkumuti. Mu nganda zitunganya amavuta yo gusiga amavuta amavuta yo kwisiga, mugihe akoreshwa mubuvuzi, amarangi, amarangi, ibikoresho byogajuru, ibirungo na electronike nizindi nganda. Umuti wino wamazi. Ikoreshwa mu kwisiga mu gukora imisumari yimisumari, nkumuti utetse cyane, irashobora kugabanya ubukonje bwimisumari, yumisha vuba.
8.Yakoreshejwe nka solvent, dewaxing agent, nayo ikoreshwa muri synthesis organique, kandi nkibikoresho fatizo kubirungo bya sintetike na farumasi.
Inyandiko zibika ibicuruzwa:
1.Bika mububiko bukonje, buhumeka.
2.Komeza kure yumuriro nubushyuhe.
3.Ubushyuhe bwo kubika ntibugomba kurenga37° C.
4.Komeza ikintu gifunze.
5.Bigomba kubikwa bitandukanye na okiside,kugabanya abakozi na alkalis,kandi ntigomba na rimwe kuvangwa.
6.Koresha ibikoresho biturika biturika kandi bihumeka.
7.Kubuza gukoresha ibikoresho bya mashini nibikoresho byoroshye kubyara ibishashi.
8.Ahantu ho kubika hagomba kuba hafite ibikoresho byihutirwa byihutirwa nibikoresho byubuhungiro.
