Ubwiza:
1. Kugaragara: 4,4′-Dichlorobenzophenone ni ibara ritagira ibara ryoroshye rya kristaline ikomeye.
3. Gukemura: Irashobora gushonga mumashanyarazi amwe n'amwe, nka ethers na alcool, ariko ntishobora gushonga mumazi.
Koresha:
1.
2. Abahuza imiti yica udukoko: Irashobora kandi gukoreshwa nkigihe gito muguhuza imiti yica udukoko.
Uburyo:
Gutegura 4,4′-dichlorobenzophenone mubusanzwe bikorwa nintambwe zikurikira:
1. Benzophenone ikora na thionyl chloride imbere ya n-butyl acetate kugirango itange 2,2′-diphenylketone.
Ibikurikira, 2,2′-diphenyl ketone ifata hamwe na thionyl chloride imbere ya aside sulfurike ikora 4,4′-dichlorobenzophenone.
Amakuru yumutekano:
1. 4,4′-Dichlorobenzophenone igomba gufata ingamba zikenewe z'umutekano mugihe cyo gufata no kubika kugirango wirinde guhura nuruhu, amaso numunwa.
2. Kwambara uturindantoki two gukingira, indorerwamo na masike mugihe ukoresha.
3. Korera ahantu hafite umwuka mwiza kandi wirinde guhumeka umwuka wacyo.
4. Mugihe uhuye nimpanuka cyangwa kuribwa, shakisha ubuvuzi bwihuse hanyuma uzane ikirango cyangwa urupapuro rwumutekano kubintu.
