Tšebeliso e itseng
Hangata e sebelisoa ho tsoakeng lintho tse phelang 'me ke karolo ea radiomiphene e thibelang ho hloka thari.
Mokhoa oa tlhahiso:
1. P-chlorobenzoyl chloride e lokisitsoe ka karabelo ea p-chlorobenzoyl chloride ka anisole, e lateloa ke hydrolysis le demethylation.
2. Karabelo ea p-chlorobenzoyl chloride le phenol: qhala 9.4g (0.1mol) ea phenol ka 4ml ea tharollo ea sodium hydroxide ea 10%, eketsa 14ml (0.110mol) ea p-chlorobenzoyl chloride ka ho theohela ka tlase ho 40 ~ 45 ℃, e kenye ka hare ho metsotso e 30, 'me u arabele mochesong o tšoanang bakeng sa 1H. Pholisetsa mochesong oa kamore, sefa 'me u omelle ho fumana 22.3g ea phenyl p-Chlorobenzoate. Poelo ke 96%, 'me ntlha ea ho qhibiliha ke 99 ~ 101 ℃.

Kotsi ea bophelo bo botle:
e baka ho teneha ha letlalo. E baka ho teneha ho hoholo ha mahlo. E ka baka ho teneha ha tsela ea ho hema.
Mehato ya tlhokomelo:
Hloekisa hantle ka mora ts'ebetso.
Apara liatlana tse sireletsang / liaparo tse sireletsang / likhalase tse sireletsang / limaske tse sireletsang.
Qoba ho hema lerole / mosi / khase / mosi / mouoane / spray.
Sebelisa feela kantle kapa ka moea o kenang hantle.
Karabelo ea kotsi:
Haeba letlalo le silafetse: hlatsoa hantle ka metsi.
Haeba letlalo le teneha: batla thuso ea bongaka.
Hlobola liaparo tse silafetseng 'me u li hlatsoe pele u li sebelisa hape
Haeba e kena mahlong: Hlatsoa ka hloko ka metsi metsotso e seng mekae. Haeba u roala lilense tsa mahlo 'me u khona ho li ntša habonolo, li ntše. Tsoela pele ho hlatsoa mahlo.
Haeba o ntse o utlwa ho teneha ha mahlo: bona ngaka/ngaka.
Haeba motho a hema ka phoso: fetisetsa motho sebakeng se nang le moya o hlwekileng mme o dule o hema hantle.
Haeba o ikutloa o sa phele hantle, letsetsa setsi sa ho ntša chefo/ngaka
Polokelo e bolokehileng:
Boloka sebakeng se nang le moea o kenang hantle. Boloka setshelo se koetsoe.
Sebaka sa polokelo se lokela ho notleloa.
Ho lahla litšila:
Lahla dikahare/dijana ho ya ka melao ya lehae.
Mekhoa ea thuso ea pele:
Ho hema: haeba o hema, fetisetsa mokuli moeeng o hloekileng.
Ho ama letlalo: hlobola liaparo tse silafetseng 'me u hlatsoe letlalo hantle ka metsi a sesepa le metsi a hloekileng. Haeba u ikutloa u sa phele hantle, bona ngaka.
Ho sheba mahlo: arola mahlo 'me u a hlatsoe ka metsi a phallang kapa letsoai le tloaelehileng. Batla thuso ea bongaka hang-hang.
Ho monya: ho hlatsa 'me u se ke ua mo hlatsa. Batla thuso ea bongaka hang-hang.
Keletso ea ho sireletsa mopholosi: fetisetsa mokuli sebakeng se sireletsehileng. Buisana le ngaka. Bontša ngaka e sebakeng seo bukana ena ea boitsebiso ba polokeho ea lik'hemik'hale.
