Acetylacetone, tseem hu ua 2, 4-pentadione, yog cov organic compound, thiab ethanol, ethanol, acetone, organic acid thiab lwm yam kev daws teeb meem organic tau siv raws li cov kuab tshuaj, rho tawm, tus neeg sawv cev, kuj tseem siv tau rau hauv kev npaj roj av ntxiv, cov roj pleev, cov tshuaj tua kab, tshuaj tua kab, dyes, thiab lwm yam.
Khoom:Acetone tsis muaj kob lossis me ntsis dej daj ua kua. Qhov cub npau npau yog 135-137 ° C, lub nyem point yog 34 ° C, thiab lub zog melting yog 0.976, tus nqi luv nqi yog n20D1.4512. Cov acetone yog soluble nyob rau hauv 8g dej, thiab nws yog tov nrog ethanol, benzene, thiab tshuaj actumoform, thiab yog cov acetone, thiab acetic acid hauv cov alkali daws. Thaum nws kub taub hau kub, taws teeb thiab muaj zog oxidant, nws yog ib qho yooj yim los ua rau muaj kev kub hnyiab. Tsis ruaj khov hauv dej, yooj yim hydrolyzed mus rau hauv acetic acid thiab acetone.
Nruab nrab rau cov synthic synthesis:
Acetylacetone yog qhov nruab nrab tseem ceeb hauv cov synthic synthesis, hloov hauv cov tshuaj, tshuaj tua kab mob thiab lwm yam kev lag luam.
Acetone yog ib qho tseem ceeb raw rau hauv kev lag luam kws tshuaj, xws li synthesis ntawm 4,6 - dimethylpaphrimididides derivatives. Nws tseem siv tau raws li cov kuab tshuaj rau cellulose acetate, ib qho desiccant rau cov xim pleev xim thiab cov varnishes, thiab anergytical reagent.
Vim tias lub hav zoov ntawm enol daim ntawv, acetylacetone tuaj yeem tsim chelates nrog cobalt (ⅱ), callalium, callal, interium, cath, zirconium, magnesium, Manganese, scandium thiab thorium thiab lwm yam hlau ions, uas tuaj yeem siv los ua cov roj ntxiv roj thiab cov roj lubricating.
Cov tshuaj lom neeg tuaj yeem siv los ua tus neeg sawv cev tu rau cov hlau hauv micropores los ntawm nws txoj kev chelation nrog hlau. Siv los ua catalyst, resin crosslinking tus neeg sawv cev, resin kho tus tsuj tshuaj; Cob, roj hmab ntxiv; Siv rau hydrroxylation Cov tshuaj tiv thaiv, cov tshuaj tiv thaiv hydrogenation, cov tshuaj tiv thaiv hydrogenization, cov tshuaj tsw qab thiab cov roj polrolysization thiab cov copolymerization; Siv raws li Organic kuab tshuaj, siv rau cellulose acetate, number case, xim. XIM DRYING TUS KHEEJ; Cov ntaub ntawv raw rau kev npaj ntawm cov tshuaj tua kab thiab cov fungicides, cov tshuaj tua kab mob thiab noj ntxiv; Infrared reflection iav, pob tshab condparing zaj duab xis (indium ntsev), superconducting zaj duab xis (Incium tus neeg sawv cev; Acetylacetone hlau ua ib qho xim tshwj xeeb (tooj liab ntsev ntsuab, chiv ntsev liab, thiab ntsev hauv dej; Siv los ua cov ntaub ntawv raw rau tshuaj; Cov khoom siv hluav taws xob organic.
Cov ntawv thov ntawm Acetyl Acetone:
1. Pentanedione, tseem hu ua acetylacetone, yog qhov nruab nrab ntawm fungictrobin, azoxystrobin thiab cov tshuaj tua kab mob rimsulfuron.
2. Nws tuaj yeem siv los ua cov ntaub ntawv raw thiab cov organic intermediates rau cov tshuaj, thiab tseem siv tau ua cov kuab tshuaj.
3. Siv los ua kev ntsuas tshuaj thiab rho tawm tus neeg sawv cev ntawm txhuas hauv tungsten thiab molybdenum.
4. Acetylacetone is an intermediate in organic synthesis, and it forms amino-4,6-dimethylpyrimidine with guanidine, which is an important pharmaceutical raw material. Nws tuaj yeem siv los ua cov kuab tshuaj rau cov roj av thiab roj nplua nyeem thiab roj nplua nyeem thiab cov kua roj kua roj vuas, thiab tshuaj tua kab, thiab tshuaj tua kab. Acetylacetone kuj tseem siv tau ua portalyst rau roj av tawg, hydrogenation thiab carbonylation tshua, thiab oxidation nrawm rau oxygen. Nws tuaj yeem siv los tshem tawm cov hlau oxides hauv cov khib nyiab ntxig thiab los kho cov polypropylene catalysts. Hauv European thiab Asmeskas lub teb chaws, ntau tshaj 50% yog siv nyob rau hauv cov tsiaj txhu antidiarpyrhodheal tshuaj thiab pub tshuaj ntxiv.
5. Ntxiv rau cov khoom siv ntawm cov cawv thiab cov khoom Ketones, nws tseem ua rau pom cov xim liab liab liab nrog ntau cov ntsev hlau. Los ntawm acetic anhydride lossis acetyl chloride thiab acetone hws, lossis los ntawm cov tshuaj tiv thaiv ntawm acetone thiab ketene tau txais. Chemicalbook is used as metal extractant to separate trivalent and tetravalent ions, paint and ink driers, pesticides, pesticides, fungicides, solvents for high polymers, reagents for the determination of thallium, iron, fluorine, and organic synthesis intermediates.
6. Kev hloov pauv cov neeg hlau. Colorimetric txiav txim siab ntawm cov hlau thiab cov tshuaj fluorine, thiab kev txiav txim siab ntawm qhov weballium nyob rau hauv muaj cov carbon disulfide.
7. Fe (iii) cov txheej txheem ua hauj lwm qhia txog lub lim tiam no; Siv rau kev hloov kho ntawm cov pab pawg guanidine (xws li arg) thiab cov amino pawg hauv cov protein.
8. Siv ua cov neeg saib xyuas cov hlau chelating; Siv rau kev txiav txim siab Colorimetric txiav txim siab ntawm cov hlau thiab cov tshuaj fluorine, thiab kev txiav txim siab ntawm kev txiav txim siab hauv lub xub ntiag ntawm cov carbon disulfide.
9. Qhov taw qhia rau cov hlau (III) cov khoom sib dhos. Siv los hloov Guanidine pawg hauv cov protein thiab cov pab pawg amino hauv cov protein.
Kev Cia Cai Cia:
1. Nyob deb ntawm Minghuo thiab muaj zog oxidant, foob thiab txuag.
2. Qhwv nws hauv lub hnab yas lossis cov roj hmab yas hauv cov khoom siv hlau; cov khoom lag luam li ib txwm ntim: 200kg-ua pov thawj, khaws cia hauv cov tsev rau khoom txaus ntshai. Cia thiab tsheb thauj mus los raws li cov cai ntawm cov tshuaj phom sij.
