Mawu Oyamba
3,5-Dichlorophenylhydrazine hydrochloride imagwiritsidwa ntchito kwambiri mu kafukufuku wamankhwala ndi labotale. Ikhoza kugwiritsidwa ntchito ngati reagent mu kaphatikizidwe organic kwa synthesis ena mankhwala, makamaka synthesis wa asafe munali mankhwala. Itha kugwiritsidwanso ntchito ngati wapakatikati pamankhwala ena.
Njira yokonzekera 3,5-Dichlorophenylhydrazine hydrochloride nthawi zambiri imapezeka pochita phenylhydrazine ndi 3,5-dichlorobenzoyl chloride. Choyamba, phenylhydrazine imawonjezeredwa popanda zosungunulira, ndiyeno 3,5-dichlorobenzoyl chloride imawonjezeredwa pang'onopang'ono kuti ipange chinthu chomwe mukufuna. Potsirizira pake, mankhwalawo anali crystallized ndi kuwonjezera hydrochloric acid kupereka mankhwala koyera.
Ponena za chidziwitso cha chitetezo, 3,5-Dichlorophenylhydrazine hydrochloride ikhoza kukhala yovulaza thanzi, choncho njira zodzitetezera ziyenera kuchitidwa pogwiritsa ntchito ndi kusamalira. Ndi chinthu chokwiyitsa ndipo chingayambitse kuyabwa m'maso, pakhungu ndi m'mapapo. Ndikoyenera kuvala magalasi odzitetezera oyenera, magolovesi ndi masks oteteza panthawi ya ntchito kuti ntchitoyo ichitike pamalo abwino mpweya wabwino. Komanso, pewani kutulutsa fumbi lake kapena kukhudzana ndi khungu. Kukhudzana ndi ma okosijeni amphamvu ndi ma asidi amphamvu kuyenera kupewedwa mukamagwiritsa ntchito ndikusunga. Zinyalala zikatayidwa, ziyenera kutayidwa motsatira malamulo a m’deralo. Ngati kutayikira kwangozi kwachitika, njira zofulumira ziyenera kuchitidwa kuti ziyeretsedwe ndikuthana nazo. Mulimonsemo, tikulimbikitsidwa kugwiritsa ntchito motsogozedwa ndi ogwira ntchito oyenerera.
