Khoom Properties:
1.Chemical Properties: Butanone raug rau ntau yam kev tshwm sim vim nws pawg carbonyl thiab cov nquag hydrogen nyob ib sab ntawm pawg carbonyl. Condensation tshwm sim thaum rhuab nrog hydrochloric acid los yog sodium hydroxide los ua 3,4-dimethyl-3-hexen-2-one los yog 3-methyl-3-hepten-5-one. Thaum raug tshav ntuj ntev, ethane, acetic acid thiab condensation cov khoom raug tsim. Thaum oxidized nrog nitric acid, biacetyl yog tsim. Thaum oxidised nrog chromic acid thiab lwm yam muaj zog oxidants, acetic acid yog generated. Butanone yog qhov ruaj khov rau cov cua sov, siab dua 500°Cthermal tawg los tsim alkenone lossis methyl alkenone. Thaum condensed nrog aliphatic los yog aromatic aldehydes, nws generates siab molecular hnyav ketones, cyclic compounds, ketones thiab resins, thiab lwm yam. Piv txwv li, thaum condensed nrog formaldehyde nyob rau hauv lub xub ntiag ntawm sodium hydroxide, nws generates bi-acetyl. Piv txwv li, condensation nrog formaldehyde nyob rau hauv lub xub ntiag ntawm sodium hydroxide ua ntej tsim 2-methyl-1-butanol-3-one thiab tom qab ntawd dehydrates los tsim methylisopropenyl ketone. Cov tshuaj no ua rau cov resination thaum raug tshav ntuj los yog ultraviolet lub teeb. Condensation nrog phenol tsim 2,2-bis (4-hydroxyphenyl) butane. Reacts nrog aliphatic esters nyob rau hauv lub xub ntiag ntawm ib tug yooj yim catalyst tsim β-diketones. Acylation nrog anhydride nyob rau hauv lub xub ntiag ntawm acidic catalyst los tsim β-diketone. Cov tshuaj tiv thaiv nrog hydrogen cyanide los tsim cyanohydrin. Reacts nrog ammonia los tsim ketopiperidine derivatives. Lub α-hydrogen atom ntawm butanone tau hloov pauv nrog halogens los tsim ntau yam halogenated ketones, xws li 3-chloro-2-butanone nrog chlorine. Kev sib cuam tshuam nrog 2,4-dinitrophenylhydrazine ua rau daj 2,4-dinitrophenylhydrazone (mp 115 ° C).
2.Stability: ruaj khov

5.Siv nyob rau hauv kev lag luam hluav taws xob, feem ntau siv los ntxuav thiab degreasing tus neeg saib xyuas.
6.Nrog rau kev siv dav hauv cov roj refining, coatings, auxiliaries, adhesives, dyes, pharmaceuticals thiab electronic Cheebtsam tu, thiab lwm yam, nws yog tsuas yog siv los ua ib qho hnyav rau nitrocellulose, yas resin, acrylic resin thiab lwm yam khoom siv hluavtaws. Nws qhov zoo yog muaj zog solubility thiab qis volatility tshaj acetone. Nyob rau hauv lub extraction ntawm zaub roj, refining txheej txheem ntawm azeotropic distillation thiab kev npaj ntawm txuj lom, antioxidants thiab lwm yam kev siv.
7.Nws tseem yog cov khoom siv raw rau cov organic synthesis thiab tuaj yeem siv los ua cov kuab tshuaj. Hauv kev lag luam roj refining rau lubricating roj dewaxing tus neeg saib xyuas, thaum siv tshuaj, xim, dyes, detergents, spices thiab electronics thiab lwm yam lag luam. Solvent rau kua number case. Siv rau hauv cov tshuaj pleev ib ce rau kev tsim cov ntsia thawv polish, raws li cov kuab tshuaj qis qis, tuaj yeem txo cov viscosity ntawm cov ntsia thawv polish, kom qhuav sai.
8.Siv raws li hnyav, dewaxing tus neeg sawv cev, kuj siv nyob rau hauv organic synthesis, thiab raws li raw cov ntaub ntawv rau hluavtaws spices thiab tshuaj.
