Momwe mungasungire: sungani mu chidebe chotsekedwa bwino. Sungani pamalo ozizira, ouma, komanso opumira bwino kutali ndi zinthu zosagwirizana.
Khola: Khola pansi pa kutentha kwabwinobwino ndi kupsinjika
Kugwiritsa ntchito kwina
Kawirikawiri imagwiritsidwa ntchito popanga zinthu zachilengedwe ndipo ndi gawo la mankhwala oletsa kubereka otchedwa radiomiphene.
Njira yopangira:
1. P-chlorobenzoyl chloride inakonzedwa pogwiritsa ntchito njira ya p-chlorobenzoyl chloride ndi anisole, kenako hydrolysis ndi demethylation.
2. Momwe p-chlorobenzoyl chloride imachitira ndi phenol: sungunulani 9.4g (0.1mol) ya phenol mu 4ml ya 10% sodium hydroxide solution, onjezerani 14ml (0.110mol) ya p-chlorobenzoyl chloride pang'onopang'ono pa 40 ~ 45 ℃, yikani mkati mwa mphindi 30, ndipo ikani kutentha komweko kwa 1H. Zizireni kutentha kwa chipinda, sefani ndi kuuma kuti mupeze 22.3g ya phenyl p-Chlorobenzoate. Zokolola zake ndi 96%, ndipo malo osungunuka ndi 99 ~ 101 ℃.

2. Momwe p-chlorobenzoyl chloride imachitira ndi phenol: sungunulani 9.4g (0.1mol) ya phenol mu 4ml ya yankho la 10% sodium hydroxide, onjezerani 14ml (0.110mol) ya p-chlorobenzoyl chloride pang'onopang'ono pa 40 ~ 45℃, yikani mkati mwa mphindi 30, ndipo chitanipo kanthu pa kutentha komweko kwa 1H. Ziziritsani kutentha kwa chipinda, sefani ndi kuumitsa kuti mupeze 22.3g ya phenyl p-Chlorobenzoate. Zokolola zake ndi 96%, ndipo kutentha kwake ndi 99 ~ 101℃.
Ngozi pa thanzi:
zimayambitsa kuyabwa pakhungu. Zimayambitsa kuyabwa kwambiri m'maso. Zingayambitse kuyabwa m'njira yopumira.
Kusamalitsa:
Tsukani bwino mukamaliza opaleshoni.
Valani magolovesi oteteza / zovala zoteteza / magalasi oteteza / masks oteteza.
Pewani kupumira fumbi / utsi / mpweya / utsi / nthunzi / kupopera.
Gwiritsani ntchito panja pokha kapena ndi mpweya wabwino.
Yankho la ngozi:
Ngati khungu laipitsidwa: sambani bwino ndi madzi.
Ngati khungu lanu layamba kuyabwa: pitani kuchipatala.
Chotsani zovala zoipitsidwazo ndipo zitsukeni musanagwiritsenso ntchito
Ngati mukuona maso: Tsukani mosamala ndi madzi kwa mphindi zochepa. Ngati muvala ma contact lens ndipo mungathe kuwachotsa mosavuta, achotseni. Pitirizani kutsuka maso.
Ngati mukumvabe kuyabwa m'maso: onani dokotala/dokotala.
Ngati mwangopumira mwangozi: muzimusamutsa munthuyo kumalo komwe kuli mpweya wabwino ndipo muzimupatsa mpweya wabwino.
Ngati simukumva bwino, imbani dokotala/chipatala kuti muchotse poizoni m'thupi.
Malo osungiramo zinthu motetezeka:
Sungani pamalo opumira bwino. Sungani chidebecho chitsekedwa.
Malo osungiramo zinthu ayenera kukhala otsekedwa.
Kutaya zinyalala:
Tayani zomwe zili mkati/zotengera malinga ndi malamulo am'deralo.
Njira zoyambira zothandizira:
Kupuma mpweya: Ngati mwapuma mpweya, sunthani wodwalayo ku mpweya wabwino.
Kukhudza khungu: vulani zovala zodetsedwa ndipo tsukani khungu bwino ndi madzi a sopo ndi madzi oyera. Ngati simukumva bwino, pitani kwa dokotala.
Kukhudza maso: siyanitsani zikope ndi kutsuka ndi madzi otuluka kapena saline wamba. Pitani kuchipatala nthawi yomweyo.
Kumeza: kutsuka mutu ndi madzi osayambitsa kusanza. Pitani kuchipatala nthawi yomweyo.
Malangizo oteteza wopulumutsa: tumizani wodwalayo pamalo otetezeka. Funsani dokotala. Onetsani dokotalayo buku la malangizo a chitetezo cha mankhwala lomwe lili pamalopo.
