Nws feem ntau yog siv rau hauv cov organic synthesis thiab yog ib qho nruab nrab ntawm cov tshuaj tiv thaiv kev tsis muaj menyuam radiomiphene
Txoj kev tsim khoom:
1. P-chlorobenzoyl chloride tau npaj los ntawm kev sib xyaw ntawm p-chlorobenzoyl chloride nrog anisole, ua raws li hydrolysis thiab demethylation.
2. Kev sib xyaw ntawm p-chlorobenzoyl chloride nrog phenol: yaj 9.4g (0.1mol) ntawm phenol hauv 4ml ntawm 10% sodium hydroxide kua, ntxiv 14ml (0.110mol) ntawm p-chlorobenzoyl chloride poob ntawm 40 ~ 45 ℃, ntxiv nws hauv 30 feeb, thiab sib xyaw ntawm tib qhov kub rau 1H. Txias rau chav sov, lim thiab ziab kom tau 22.3g ntawm phenyl p-Chlorobenzoate. Cov txiaj ntsig yog 96%, thiab qhov chaw yaj yog 99 ~ 101 ℃.

Txias rau qhov kub hauv chav, lim thiab ziab kom tau 22.3g ntawm phenyl p-Chlorobenzoate. Cov txiaj ntsig yog 96%, thiab qhov melting point yog 99 ~ 101℃.
Kev phom sij rau kev noj qab haus huv:
ua rau khaus tawv nqaij. Ua rau khaus qhov muag heev. Tej zaum yuav ua rau khaus txoj kev ua pa.
Cov kev ceev faj:
Ntxuav kom huv si tom qab ua haujlwm.
Hnav cov hnab looj tes tiv thaiv / khaub ncaws tiv thaiv / tsom iav tiv thaiv / lub ntsej muag tiv thaiv.
Tsis txhob ua pa plua plav / pa luam yeeb / roj / pa luam yeeb / pa dej / tshuaj tsuag.
Siv sab nraum zoov xwb los yog muaj cua nkag zoo.
Kev teb rau qhov xwm txheej:
Yog tias muaj kab mob ntawm daim tawv nqaij: ntxuav kom huv si nrog dej.
Yog tias daim tawv nqaij khaus: nrhiav kev kho mob.
Tshem cov khaub ncaws uas muaj kuab paug thiab ntxuav ua ntej siv dua
Yog tias nkag rau hauv qhov muag: Yaug kom huv si nrog dej rau ob peb feeb. Yog tias koj hnav cov iav sib cuag thiab yooj yim tshem tawm, muab tshem tawm. Txuas ntxiv yaug.
Yog tias koj tseem hnov mob qhov muag: mus ntsib kws kho mob / kws kho mob.
Yog tias ua pa tsis tau: coj tus neeg mus rau qhov chaw uas muaj cua ntshiab thiab ua pa kom xis nyob.
Yog koj xav tias koj tsis zoo, hu rau qhov chaw tshem tshuaj lom / kws kho mob
Kev khaws cia kom muaj kev nyab xeeb:
Khaws cia rau qhov chaw uas muaj cua nkag tau zoo. Kaw lub thawv kom nruj.
Qhov chaw cia khoom yuav tsum tau xauv.
Kev pov tseg pov tseg:
Pov tseg cov ntsiab lus / thawv raws li cov cai hauv zos.
Cov kev ntsuas kev pab thawj zaug:
Kev ua pa: yog tias ua pa, tsiv tus neeg mob mus rau qhov chaw muaj huab cua ntshiab.
Kev kov daim tawv nqaij: hle cov khaub ncaws uas muaj kab mob tawm thiab ntxuav daim tawv nqaij kom huv si nrog dej xab npum thiab dej ntshiab. Yog tias koj xav tias tsis zoo, mus ntsib kws kho mob.
Yog koj kov qhov muag: cais koj ob lub qhov muag thiab yaug nrog dej ntws los yog dej ntsev. Nrhiav kev kho mob tam sim ntawd.
Haus: yaug qhov ncauj thiab tsis txhob ua kom ntuav. Nrhiav kev kho mob tam sim ntawd.
Cov lus qhia los tiv thaiv tus neeg cawm neeg: coj tus neeg mob mus rau qhov chaw nyab xeeb. Sab laj nrog kws kho mob. Qhia phau ntawv qhia kev nyab xeeb tshuaj no rau tus kws kho mob ntawm qhov chaw.
