Mawu Oyamba
4-Chloro-4′-hydroxybenzophenone ndi organic pawiri. Zotsatirazi ndizo zokhudzana ndi katundu, ntchito, njira zokonzekera, ndi chitetezo cha pawiri:
Ubwino:
Maonekedwe: 4-Chloro-4'-hydroxybenzophenone ndi woyera crystalline kapena crystalline ufa.
Kusungunuka: kusungunuka mu ethanol, dimethylformamide ndi chloroform, kusungunuka pang'ono mu etha ndi carbon chloride.
Gwiritsani ntchito:
4-Chloro-4'-hydroxybenzophenone angagwiritsidwe ntchito ngati wapakatikati mu kaphatikizidwe organic kwa kaphatikizidwe zina organic mankhwala.
Njira:
4-Chloro-4′-hydroxybenzophenone angapezeke m'malo sodium sulfite ndi sodium thiothioreagent (mwachitsanzo, phthathiadine) wa sodium sulfite. Njira yeniyeni yokonzekera ndi iyi:
Phthamethamidine imasungunuka mu dimethylformamide, hydroxyacetophenone imawonjezeredwa ku njira yothetsera, pambuyo pa nthawi inayake, madzi amawonjezeredwa, ndipo mankhwalawa amachotsedwa, owuma ndi crystallized ndi chloroform kuti apeze mankhwala omwe akugwiritsidwa ntchito.
Zambiri Zachitetezo:
4-Chloro-4'-hydroxybenzophenone imakhala yokhazikika pansi pazikhalidwe zambiri. Komabe, kukhudzana ndi oxidizing amphamvu kuyenera kupewedwa.
Zida zodzitetezera zoyenerera monga magolovesi, magalasi, ndi mikanjo ziyenera kuvalidwa pochita zimenezi.
Iyenera kusungidwa kutali ndi zinthu zoyaka ndi kutentha, ndi kusungidwa mu chidebe chotchinga mpweya kuti isatengeke ndi mpweya.
Chonde tayani chigawocho ndi zinyalala zake moyenera, potsatira malamulo oyendetsera zinyalala m'deralo.
