Mawu Oyamba
4,4'-Dimethylbenzophenone. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 4,4′-dimethylbenzophenone:
Ubwino:
4,4'-Dimethylbenzophenone ndi crystalline yolimba yopanda mtundu yomwe imasungunuka bwino m'madzi kutentha kwa firiji, koma imasungunuka muzitsulo za organic monga ma alcohols ndi esters.
Ntchito: Itha kugwiritsidwanso ntchito ngati kaphatikizidwe ka organic kaphatikizidwe kazinthu zina.
Njira:
Njira yokonzekera yomwe imagwiritsidwa ntchito nthawi zambiri imakonzedwa ndi momwe benzophenone ndi n-butylformaldehyde amachitira pansi pamikhalidwe yamchere. Masitepe apadera a kaphatikizidwe angaphatikizepo kubadwa kwa mchere wa diazonium wa ketoni kapena oxime, womwe umachepetsedwa kukhala 4,4'-dimethylbenzophenone.
Zambiri Zachitetezo:
Mbiri yachitetezo cha 4,4'-dimethylbenzophenone ndiyokwera, koma izi ziyenera kudziwidwa:
- Zitha kukhala zokhumudwitsa m'maso ndi pakhungu, choncho samalani mukazigwiritsa ntchito.
- Pewani kutulutsa fumbi kapena kukhudza njira yake kuti mupewe kusapeza bwino kapena kuyabwa.
- Pewani kukhudzana ndi malawi otseguka mukamagwiritsa ntchito, ndipo sungani kutali ndi malawi otseguka komanso kutentha kwambiri.
- Gwiritsani ntchito motsogozedwa ndi akatswiri ndikutsata njira zoyenera zotetezera.
