Khoom molecular qauv:

Cov Lus Qhia Tshwj Xeeb:

Tshuaj Tshuaj Muaj Zog:

Methyl Ketone muaj kev cuam tshuam rau ntau yam kev tawm tsam vim nws cov pab pawg carbonyl thiab cov nquag hydrogen uas nyob ib sab rau pawg carbonyL. Cov hws muaj tshwm sim thaum ua kom sov nrog hydrochloric acid lossis sodium hydroxide los tsim 3,4-dimethyl-3-heelen-2-ib lossis 3-epten-5-ib. Thaum nthuav tawm lub hnub ci rau lub sijhawm ntev, txaj muag, acetic acid thiab cov hws cov khoom lag luam yog tsim tawm. Tsim cov diacetyl thaum oxidized nrog nitric acid. Thaum oxidized nrog oxidizing oxidizing cov neeg sawv cev xws li chromic acid, acetic acid, acid yog tsim. Butanone yog tus nyob ruaj khov rau cua sov, thiab thermal cleavage ntawm cov chaw kub siab dua ua rau enone lossis methyl enone. Thaum yuj siab nrog aliphatic lossis cov ntxhiab tsw qab zib, cyclics cov hws, Ketne hws thiab cov txiaj ntsig ketsis thiab cov dab tsi yog tsim tawm. Piv txwv li, hws nrog formaldehyde nyob rau hauv lub xub ntiag ntawm sodium hydroceide ua ntej 2-methyl-3-itanol-1-ib, tom qab los ntawm lub cev qhuav dej rau methacrylatone.
Kev kho mob tshwm sim thaum kis tau lub hnub ci lossis UV teeb. Cov hws nrog phenol yields 2,2-bis (4-hydroxyphenyl) butane. Reacts nrog aliphatic estres nyob rau hauv lub xub ntiag ntawm cov catalyst los tsim β-diketones. Acylation nrog acidic anhydride nyob rau hauv muaj ntawm ib qho acidic catalyst los ua β-diketones. Reacts nrog hydrogen cyanide mus rau cov ntawv cyanohydrin. Reacts nrog ammonia los tsim ketopiperididides derivatives. Ullo-hydrogen atom ntawm Butanone yog qhov yooj yim hloov nrog Halogens los tsim ntau yam Halogenated Ketoones, xws li 3-chloro-2-Butanone los ntawm kev sib cuam tshuam nrog chlorine. Kev sib cuam tshuam nrog 2,4-dinitropsenyrdhydrhydrazine ua daj 2,4-dinitropsenylhydrhydrazone.

Daim Ntawv Thov:

Methyl ketone (2-butanone, ethyl methyl ketone, methyl acetone) yog ib qho muaj kuab lom, uas muaj nyob hauv ntau daim ntawv thov. Nws yog siv rau hauv cov khoom lag luam thiab cov khoom lag luam raws li cov kuab tshuaj rau cov nplaum, xim, thiab cov kuab tshuaj tua kab mob thiab ua cov kuab tshuaj tua kab. Ib lub ntuj tivthaiv ntawm qee cov zaub mov, methyl ketyl Ketone tuaj yeem tso tawm rau hauv ib puag ncig ntawm cov khoom siv hluav taws xob thiab cov kuab tshuaj zoo nkauj, ua cov kuab tshuaj tsis zoo, thiab cov txheej txheem hluav taws xob, thiab cov txheej txheem insurface. Nws tseem raug siv los ua cov khoom noj nyob hauv cov zaub mov.

Mek yog siv los ua qhov hnyav rau ntau cov txheej txheem txheej ntau txheej, piv rau, cov nplaum yas, cov nplaum, thiab pleev pleev xim acrylic. Nws yog siv rau hauv cov xim tshem tawm, varnishes, varnishes, freeders, luam yeeb, rosins, cov kev daws teeb meem, thiab rau polymerization. Nws pom nyob rau hauv lwm cov neeg siv khoom siv, piv txwv, tsev neeg thiab cov kev nyiam ua si, thiab cov khoom lag luam ntoo. Mek yog siv nyob rau hauv dewaxing roj lubricating roj, hauv kev tsim cov hluavtaws, hauv ntawv ci thiab ua tshuaj lom neeg thiab catalyst. Nws yog kev rho tawm cov kuab tshuaj hauv kev ua cov khoom noj khoom haus thiab cov khoom noj khoom noj. Mek kuj tseem siv tau los cais kev phais thiab kho hniav.
Ntxiv rau nws cov chaw tsim khoom, ib puag ncig cov khoom ntawm mek suav nrog tso tawm ntawm lub dav hlau thiab cov haujlwm sab hauv xws li ua pa ntawm cov thee. Nws pom nyob rau hauv cov nyiaj haus luam yeeb ntau. Mek ua rau muaj kev lom neeg thiab tau txheeb xyuas tias yog cov khoom lag luam metabolism. Nws tau kuj tau pom hauv cov nroj tsuag, kab noj tsiaj, thiab mek tej zaum yog cov khoom me me ntawm cov memalian metabolism hauv cov metabolism hauv lub cev. Nws yog ruaj khov nyob rau hauv cov xwm txheej zoo tib yam tab sis tuaj yeem tsim peroxides ntawm lub caij nyoog cia; Cov no yuav tawg tau.
