Ntchito yeniyeni
Amagwiritsidwa ntchito popanga organic synthesis ndipo ndi wapakatikati wa anti infertility drug radiomiphene.
Njira yopangira:
1. P-chlorobenzoyl chloride inakonzedwa ndi zomwe p-chlorobenzoyl kolorayidi ndi anisole, kenako hydrolysis ndi demethylation.
2. Kuchita kwa p-chlorobenzoyl chloride ndi phenol: Sungunulani 9.4g (0.1mol) wa phenol mu 4ml wa 10% sodium hydroxide solution, onjezerani 14ml (0.110mol) wa p-chlorobenzoyl chloride dropwise pa 40 ~ 45 ℄ 30min, ndikuchitapo pa kutentha komweko kwa 1H. Kuzizira mpaka kutentha kwa chipinda, fyuluta ndi kuuma kuti mupeze 22.3g ya phenyl p-Chlorobenzoate. Zokolola ndi 96%, ndipo malo osungunuka ndi 99 ~ 101 ℃.

Ngozi yaumoyo:
kuyambitsa khungu kuyabwa. Zimayambitsa kuyabwa kwambiri m'maso. Zingayambitse kupuma thirakiti kuyabwa.
Kusamalitsa:
Tsukani bwino pambuyo opareshoni.
Valani magolovesi oteteza / zovala zoteteza / magalasi oteteza / masks oteteza.
Pewani kutulutsa fumbi / utsi / gasi / utsi / nthunzi / utsi.
Gwiritsani ntchito kunja kokha kapena ndi mpweya wabwino.
Yankho langozi:
Pakhungu pakhungu: sambani bwino ndi madzi.
Pakhungu pakhungu: pitani kuchipatala.
Chotsani zovala zomwe zawonongeka ndikuzichapa musanagwiritse ntchito
Ngati m'maso: Muzimutsuka mosamala ndi madzi kwa mphindi zingapo. Ngati mumavala ma contact lens ndipo mutha kuwatulutsa mosavuta, atulutseni. Pitirizani kupukuta.
Ngati mukumvabe kukwiya m'maso: onani dokotala / dokotala.
Ngati wapuma mwangozi: kusamutsa munthuyo kumalo okhala ndi mpweya wabwino ndikukhalabe ndi mpweya wabwino.
Ngati simukumva bwino, imbani detoxification center/dotolo
Malo otetezedwa:
Kusunga bwino podutsa mpweya malo. Sungani chidebecho chotsekedwa.
Malo osungira ayenera kukhala okhoma.
Kutaya zinyalala:
Tayani zamkati / zotengera molingana ndi malamulo amderali.
Thandizo loyamba:
Kukoka mpweya: Ngati mupuma, sunthirani wodwalayo ku mpweya wabwino.
Kukhudza Pakhungu: Chotsani zovala zomwe zili ndi kachilombo ndikutsuka khungu bwino ndi madzi a sopo ndi madzi oyera. Ngati mukumva kuti simukupeza bwino, onani dokotala.
Kuyang'ana m'maso: Pakani zikope ndikutsuka ndi madzi oyenda kapena saline wamba. Pitani kuchipatala mwamsanga.
Kumeza: gwedezani ndipo musapangitse kusanza. Pitani kuchipatala mwamsanga.
Malangizo oteteza wopulumutsa: kusamutsa wodwalayo kumalo otetezeka. Funsani dokotala. Onetsani adotolo patsamba lino buku laukadaulo lachitetezo chamankhwala.
