| Zizindikiro Zowopsa | 36/37/38 - Zokwiyitsa maso, kupuma komanso khungu. |
| Kufotokozera Zachitetezo | 24/25 - Pewani kukhudzana ndi khungu ndi maso. |
Mawu Oyamba
3,4-Dimethylbenzophenone, yomwe imadziwikanso kuti ketocarbonate kapena Benzoin. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
-Maonekedwe: 3,4-Dimethylbenzophenone ndi woyera crystalline olimba.
-Kusungunuka: Ndi pafupifupi osasungunuka m'madzi, ndipo imakhala ndi kusungunuka kwakukulu mu zosungunulira za organic monga ethanol ndi dimethylformamide.
- Malo osungunuka: Malo osungunuka a 3,4-dimethylbenzophenone ndi pafupifupi 132-134 madigiri Celsius.
-Chemical properties: Ndi electrophilic reagent yomwe imatha kutenga nawo mbali pazochitika zosiyanasiyana monga hydrogen bond formation, oxidation-reduction reaction pakati pa ketone carbon ndi methyl.
Gwiritsani ntchito:
- 3,4-Dimethyl benzophenone makamaka ntchito ngati reagent kwa organic synthesis zimachitikira.
-Itha kugwiritsidwa ntchito ngati electrophilic reagent kutenga nawo gawo pazowonjezera za electrophilic, mapangidwe a ketone carbonate ndi zina.
-Itha kugwiritsidwanso ntchito ngati photosensitizer ya lithography, kuchiritsa kopepuka ndi zina.
Njira Yokonzekera:
Njira imodzi yokonzekera -3,4-dimethyl benzophenone ndi kaphatikizidwe ka barone. Zotsatira zake ndi izi: Choyamba, styrene imayendetsedwa ndi bromine yochulukirapo pansi pa kuwala kapena kuwala kwa ultraviolet kupanga β-bromostyrene. β-bromostyrene imayendetsedwa ndi hydroxide (mwachitsanzo, NaOH) kupanga 3,4-dimethylbenzophenone.
- Njira ina yokonzekera ndikuchita acetophenone ndi sodium bromide pansi pa zinthu zamchere kuti apange 3,4-dimethyl benzophenone.
Zambiri Zachitetezo:
- 3,4-Dimethylbenzophenone ndi yochepa poizoni.
-Pewani kukhudzana ndi khungu ndi kupuma pamene mukugwiritsa ntchito.
-Ruyi kunja kukhudzana ndi khungu, ayenera nthawi yomweyo muzimutsuka ndi madzi ambiri.
-Akauzira mpweya, sunthani nthawi yomweyo pamalo opumira bwino.
- Ndi bwino kuvala magolovesi oteteza oyenerera ndi zida zopumira panthawi yogwira ntchito.
-Pogwiritsa ntchito ndikusunga, chonde tsatirani njira zotetezeka zogwirira ntchito ndikuyiyika kutali ndi ana.
