Taw qhia
Phenophenol, tseem hu ua benzene sulfide, yog xim tsis muaj xim rau lub teeb daj. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm phenol:
Zoo:
- Cov tsos mob: Phenophenol yog cov xim tsis muaj xim rau lub teeb daj nrog cov ntxhiab tsw ntxhiab thiophenol.
- Solubility: Phenophenol yog insoluble hauv dej, tab sis soluble nyob rau hauv ntau cov organic solvents xws li cawv, ethers, cawv ethers, thiab lwm yam.
- Reactivity: Phenophenol yog electrophilic thiab muaj peev xwm undergo acid-base neutralization, oxidation, thiab hloov.
Siv:
- Kev lag luam tshuaj: Phenophenol tuaj yeem siv los ua qhov nruab nrab hauv kev tsim cov dyes, plastics, thiab roj hmab.
- Cov tshuaj tua kab mob: Phenol muaj qee yam tshuaj tua kab mob, pwm inhibition thiab tshuaj tua kab mob, thiab yog siv dav hauv kev tiv thaiv ntoo, pleev xim, nplaum thiab lwm yam.
Txoj kev:
Phenol tuaj yeem npaj los ntawm cov tshuaj tiv thaiv ntawm benzenesulfonyl chloride nrog sodium hydrosulfide. Hauv cov tshuaj tiv thaiv, benzenesulfonyl chloride reacts nrog sodium hydrogen sulfide los ua benzene mercaptan, uas tom qab ntawd oxidized kom tau phenylthiophenol.
Cov ntaub ntawv kev nyab xeeb:
- Phenophenol ua rau khaus thiab tuaj yeem ua rau mob rau ntawm daim tawv nqaij lossis qhov muag. Kev sib cuag ncaj qha rau ntawm daim tawv nqaij thiab qhov muag yuav tsum zam thaum siv thiophenol, thiab cov hnab looj tes tiv thaiv thiab tsom iav yuav tsum hnav yog tias tsim nyog.
- Phenophenol yog tshuaj lom rau ib puag ncig thiab yuav tsum zam kom tsis txhob muaj qhov dej loj thiab tawm mus rau hauv dej los yog av.
- Phenophenol yog volatile thiab tej zaum yuav ua rau cov tsos mob xws li kiv taub hau thiab xeev siab yog tias raug rau nws nyob rau hauv ib tug unventilated ib puag ncig ntev. Ib qho chaw ua haujlwm tau zoo yuav tsum tau khaws cia thaum siv phenothiophenol.
