Mawu Oyamba
4,4'-Dimethoxybenzophenone, wotchedwanso DMPK kapena Benzilideneacetone dimethyl acetal, ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha gululi:
Ubwino:
4,4′-Dimethoxybenzophenone ndi madzi achikasu otuwa opanda mtundu komanso fungo la benzene. Imatha kuyaka, imakhala ndi kachulukidwe kakang'ono kwambiri, ndipo imasungunuka muzosungunulira wamba monga ethanol, ethers, ndi ketoni. Ndi yosakhazikika ku mpweya ndi kuwala ndipo imatha kukumana ndi ma oxidation reaction.
Gwiritsani ntchito:
4,4'-dimethoxybenzophenone nthawi zambiri amagwiritsidwa ntchito ngati chothandizira kapena reagent mu kaphatikizidwe ka organic ndipo ali ndi ntchito yayikulu. Mu kaphatikizidwe organic, angagwiritsidwe ntchito pokonza aldehydes, ketoni, etc.
Njira:
Njira yokonzekera ya 4,4′-dimethoxybenzophenone ikhoza kutheka ndi condensation reaction ya dimethoxybenzosilane ndi benzophenone. Dimethoxybenzosilane imayendetsedwa ndi sodium borohydride kuti ipeze boranol, kenako imalumikizidwa ndi benzophenone kuti ipeze 4,4′-dimethoxybenzophenone.
Zambiri Zachitetezo:
4,4′-Dimethoxybenzophenone imakwiyitsa khungu ndipo ingayambitse kupsa mtima kwa maso ndi kupuma. Njira zodzitetezera zoyenera monga magolovesi, magalasi, ndi zopumira ziyenera kuvalidwa pogwira ndikugwiritsa ntchito. Pakusungidwa, ziyenera kusungidwa pamalo ozizira, owuma, kutali ndi kuyatsa ndi okosijeni. Chonde tsatirani njira zotetezeka zogwirira ntchito ndikutsata malamulo ndi zofunikira zonse. Pakachitika ngozi, njira zoyenera zadzidzidzi ziyenera kuchitidwa nthawi yomweyo.
