Taw qhia
Hexafluorobutyl methacrylate. Cov hauv qab no yog cov lus qhia ntxaws ntxaws txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm hexafluorobutyl methacrylate:
Zoo:
1. Cov tsos: cov kua tsis muaj xim.
3. Ceev: 1.35 g / cm³.
4. Solubility: soluble nyob rau hauv organic solvents, xws li methanol, ethanol, ether thiab methylene chloride, insoluble nyob rau hauv dej.
Siv:
1. Raws li surfactant: Hexafluorobutyl methacrylate tuaj yeem siv rau hauv kev npaj cov surfactants, thiab feem ntau yog siv rau hauv kev sib xyaw ntawm cov coatings thiab inks nrog lub zog saum npoo.
2. Kev npaj cov polymers tshwj xeeb: Hexafluorobutyl methacrylate tuaj yeem siv los ua monomer ntawm cov polymers tshwj xeeb los npaj cov khoom siv tshwj xeeb, xws li kub tsis kam, tshuaj tiv thaiv corrosion, thiab lwm yam.
Txoj kev:
Hexafluorobutyl methacrylate tuaj yeem npaj los ntawm hydrofluoric acid-catalyzed gas-phase fluorination. Cov kauj ruam tshwj xeeb yog sib tov hexafluorobutyl acrylate vapor nrog methanol vapor, thiab mus los ntawm hydrofluoric acid catalytic cov tshuaj tiv thaiv los tsim hexafluorobutyl methacrylate.
Cov ntaub ntawv kev nyab xeeb:
1. Hexafluorobutyl methacrylate ua rau khaus thiab yuav ua rau khaus, kub hnyiab thiab lwm yam tsis xis nyob thaum sib cuag nrog daim tawv nqaij, qhov muag lossis ua pa. Cov iav tiv thaiv tsim nyog yuav tsum hnav thaum siv.
2. Hexafluorobutyl methacrylate yog flammable, tsis txhob sib cuag nrog qhib nplaim taws los yog kub kub.
3. Thaum siv los yog khaws cia, tsis txhob sib cuag nrog cov khoom xws li oxidants, muaj zog acids los yog alkalis muaj zog kom tsis txhob muaj kev phom sij txaus ntshai.
4. Kev pov tseg pov tseg yuav tsum ua raws li cov cai thiab cov cai hauv cheeb tsam ib puag ncig, thiab yuav tsum tsis txhob muab pov tseg raws li qhov xav tau.
