4--[2-(3 4-dimethylphenyl)-1 1 1 3 3 3-hexafluoropropan-2-yl]-1 2-dimethylbenzene(CAS# 65294-20-4)

Mawu Oyamba

2,2-bis (3,4-dimethylphenyl) hexafluoropropane ndi organic pawiri ndi mankhwala chilinganizo C20H18F6. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:

Chilengedwe:

2,2-bis (3,4-dimethylphenyl)hexafluoropropane ndi madzi achikasu otuwa komanso opanda mphamvu ya nthunzi. Ili ndi kulemera kwa mamolekyulu 392.35g/mol, kachulukidwe pafupifupi 1.20-1.21g/mL (20°C), ndi kuwira kwa pafupifupi 115-116°C.

Gwiritsani ntchito:

2,2-bis (3,4-dimethylphenyl) hexafluoropropane imagwiritsidwa ntchito makamaka ngati chokhazikika komanso chosungira ma polima. Itha kuwonjezeredwa kuzinthu zapulasitiki ndi mphira kuti zithandizire kukana kwa okosijeni komanso kukana kutentha. Kuphatikiza apo, itha kugwiritsidwanso ntchito pazinthu zamagetsi monga ma polima a thermoplastic, zomatira, zokutira ndi utomoni.

Njira:

Kukonzekera kwa 2,2-bis (3,4-dimethylphenyl) hexafluoroppane nthawi zambiri kumatheka ndi fluorination reaction ya aniline. Choyamba, Aniline amachitira ndi hydrofluoric acid kupanga aniline fluoride, ndiyeno pambuyo pa electrophilic substitution reaction, aniline fluoride imachita ndi trans-carbon tetrafluoride kupanga chinthu chomwe akufuna.

Zambiri Zachitetezo:

2,2-bis (3,4-dimethylphenyl) hexafluoropropane ili ndi kawopsedwe kakang'ono pansi pa ntchito zamafakitale. Komabe, monga mankhwala, ndikofunikirabe kusamala kugwiritsa ntchito moyenera. Mukakhudza khungu kapena maso, muzimutsuka nthawi yomweyo ndi madzi ambiri. Pogwiritsira ntchito kapena kusunga, tcheru chiyenera kulipidwa kuti mukhale kutali ndi moto ndi oxidizing agents ndikupewa kukhudzana ndi oxidizing amphamvu ndi ma asidi amphamvu. Kuvala zida zodzitetezera zoyenera monga magolovesi oteteza, magalasi ndi zovala zodzitchinjiriza ndizovomerezeka pogwira ntchito imeneyi.
