Khoom Properties:
1.Nws yog miscible nrog feem ntau cov kuab tshuaj organic xws li ethanol, ether, benzene thiab tsiaj thiab zaub roj. Nws yog ib qho hnyav heev rau cellulose nitrate, polyvinyl chloride, polyvinyl acetate, polystyrene, epoxy resin, ntuj thiab hluavtaws roj hmab, DDT, 2,4-D thiab ntau yam organic. Muaj peev xwm tsim tau rau hauv cov tshuaj viscosity tsawg los tiv thaiv gelation.
2.Chemical zog: carbonyl pawg nyob rau hauv lub molecule thiab cov nyob sib ze hydrogen atoms yog nplua nuj nyob rau hauv chemical reactivity, tshuaj muaj pes tsawg leeg zoo ib yam li butanone. Piv txwv li, thaum oxidised los ntawm cov muaj zog oxidising agents xws li chromic acid, nws generates acetic acid, isobutyric acid, isovaleric acid, carbon dioxide thiab dej. Catalytic hydrogenation muab 4-methyl-2-pentanol. Ib qho khoom ntxiv yog tsim nrog sodium bisulfite. Condensation nrog lwm cov carbonyl compounds nyob rau hauv lub xub ntiag ntawm ib tug yooj yim catalyst. Condensation nrog hydrazine los tsim hydrazone thiab Claisen condensation cov tshuaj tiv thaiv nrog ethyl acetate.
3.Stability: ruaj khov
4. Cov tshuaj txwv tsis pub:Scov oxidants,muaj zog txo cov neeg ua haujlwm, lub hauv paus muaj zog
5.Polymerisation txaus ntshai:Tsis yog polymerisation
Khoom siv:
1.Cov khoom no tuaj yeem siv los ua cov kuab tshuaj rau txhua yam kev lag luam txheej, nrog rau cov kuab tshuaj rau kev tsim cov xim qib siab rau tsheb, inks, cassette tapes, video tapes thiab lwm yam. Nws kuj yog siv los ua ore hnav khaub ncaws tus neeg saib xyuas, roj dewaxing tus neeg saib xyuas thiab cov xim pleev xim rau xim zaj duab xis.
2.Nws kuj muaj zoo heev solubility rau organometallic tebchaw. Lub peroxide ntawm cov khoom no yog ib qho tseem ceeb pib hauv cov tshuaj tiv thaiv polymerization ntawm polyester resins. Nws kuj yog siv los ua hnyav rau cov organic synthesis thiab atomic absorption spectrophotometric tsom xam.
3.Nws yog siv los ua hnyav. Ntxiv rau cov xim ntau, xim strippers, ntau yam khoom siv hluavtaws ua cov kuab tshuaj, tab sis kuj siv los ua cov nplaum, DDT, 2,4-D, pyrethroids, penicillin, tetracycline, roj hmab kua nplaum, atomic absorption spectrophotometric tsom xam ntawm lub kuab tshuaj.
4.Nws kuj muaj zoo heev solubility rau organometallic tebchaw. Nws kuj yog siv los ua ore hnav khaub ncaws tus neeg saib xyuas, roj dewaxing tus neeg saib xyuas thiab cov xim pleev xim rau xim zaj duab xis. Kuj tseem muaj qee cov ntsev ntsev uas muaj txiaj ntsig zoo sib cais, tuaj yeem sib cais los ntawm uranium plutonium, niobium los ntawm tantalum, zirconium los ntawm hafnium, thiab lwm yam.
5.Siv raws li kev tshuaj ntsuam reagent, xws li chromatographic tsom xam cov qauv. Kuj tseem siv los ua cov kuab tshuaj, cov tshuaj rho tawm.
6.Siv hauv kev tsim cov ntsia thawv polish hauv tshuaj pleev ib ce. Nyob rau hauv cov ntsia thawv polish raws li ib tug nruab nrab-boiling point hnyav (100 ~ 140 ° C), muab ntsia thawv polish kom kis, inhibit qhov fuzzy lawm.
7.Siv raws li cov kuab tshuaj rau cov tshuaj tsuag xim, nitrocellulose, ib co fiber ethers, camphor, roj, ntuj thiab hluavtaws roj hmab.
Cov ntawv khaws cia khoom:
1. Khaws rau hauv qhov chaw txias, cua txias.
2. Khaws kom deb ntawm qhov hluav taws kub thiab cua sov.
3.Qhov kub cia yuav tsum tsis pub tshaj 37 ° C.
4. Khaws lub thawv kaw.
5.Nws yuav tsum tau muab cais los ntawm cov neeg ua haujlwm oxidizing,txo cov neeg ua haujlwm thiab alkalis,thiab yuav tsum tsis txhob sib xyaw.
6.Siv cov khoom tawg-pov thawj teeb pom kev zoo thiab cov chaw ua pa.
7. Txwv tsis pub siv cov cuab yeej siv tshuab thiab cov cuab yeej uas yooj yim los tsim cov pob zeb.
8.Qhov chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm ceev thiab cov khoom siv vaj tse tsim nyog.
