Taw qhia
1,1,3,3,3-Pentafluoro-1-propene yog cov organic compound. Nws yog cov kua uas tsis muaj xim tsis muaj roj uas muaj ntxhiab tsw ntxhiab ntawm chav tsev kub. Hauv qab no yog cov lus qhia ntxaws ntxaws txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 1,1,3,3,3-pentafluoro-1-propylene:
Zoo:
Nws yog insoluble nyob rau hauv dej nyob rau hauv chav tsev kub, tab sis nws muaj peev xwm soluble nyob rau hauv organic solvents xws li cawv, ethers, thiab lwm yam. Cov khoom muaj vapor siab thiab volatility, thiab yog irritating rau lub qhov muag, ua pa ib ntsuj av tau thiab daim tawv nqaij nyob rau hauv lub vapor xeev.
Siv:
1,1,3,3,3-Pentafluoro-1-propene yog ib qho tseem ceeb nruab nrab siv nyob rau hauv synthesis ntawm lwm cov organic tebchaw. Cov ntawv thov tshwj xeeb suav nrog:
- Siv los ua cov khoom siv kho qhov muag, xws li kev npaj cov fluorescent dyes, pob tshab conductive films, thiab lwm yam .;
- Siv los ua cov khoom siv hauv cov iav tiv thaiv, cov txheej txheem kho qhov muag, cov txheej txheem polymer, thiab lwm yam.;
- Siv nyob rau hauv cov synthesis ntawm surfactants, polymers, thiab lwm yam.
Txoj kev:
Kev npaj ntawm 1,1,3,3,3-pentafluoro-1-propylene yog ua tiav los ntawm cov tshuaj tiv thaiv ntawm 1,1,3,3,3-pentachloro-1-propylene nrog hydrogen fluoride. Cov tshuaj tiv thaiv yuav tsum tau ua nyob rau hauv qhov tsim nyog qhov kub thiab txias, thiab ib tug catalyst yog siv los txhim kho cov efficiency ntawm cov tshuaj tiv thaiv.
Cov ntaub ntawv kev nyab xeeb:
1,1,3,3,3-Pentafluoro-1-propene yog cov organic compound uas ua rau khaus thiab volatile. Thaum tuav cov tshuaj no, yuav tsum tau ceev faj txog kev nyab xeeb hauv qab no:
- Siv cov cuab yeej tiv thaiv tus kheej xws li hnab looj tes tiv thaiv, tsom iav, thiab hnav ris tsho;
- Ua haujlwm nyob rau hauv qhov chaw zoo-ventilated kom tsis txhob nqus pa;
- Tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag, yaug tam sim nrog dej yog tiv tauj;
- Nws yog txwv tsis pub tso cov tshuaj mus rau hauv cov dej los yog ib puag ncig, thiab ua raws li cov cai hauv cheeb tsam.
