Phenol liabyog ib qho triphenylmethane-hom organic reagent nrog cov qauv molecular ntawm C19H14O5S thiab molecular hnyav ntawm 354.38. Nws yog xim liab mus rau tsaus liab crystalline hmoov. Nws yog ruaj khov nyob rau hauv nruab nrab kub thiab siab, tab sis nws yuav tsum tau khaws cia kom deb ntawm cov khoom oxidants thiab kaw nyob rau hauv ib qho chaw txias. Soluble hauv ethanol, sodium hydroxide, thiab sodium carbonate tov, insoluble hauv chloroform
thiab ether. Me ntsis soluble nyob rau hauv dej, yooj yim soluble nyob rau hauv ethanol thiab alkali tov, 1g ntawm cov khoom no yog soluble nyob rau hauv 1300ml dej, txog 350ml ntawm cawv, 500ml ntawm acetone, yuav luag insoluble nyob rau hauv ether thiab chloroform, soluble nyob rau hauv alkali hydroxide los yog alkali carbonate tov, tsaus. liab, ruaj khov hauv huab cua. Nws yog siv los ua raw khoom rau kev tsim phenolic resin, kapuron, thiab adipic acid, nrog rau hauv cov yas thiab tshuaj industries. Acid-base qhia; Kev txiav txim siab tag nrho cov ntshav carbon dioxide; Qhov taw qhia rau kev npaj disaccharide urea kab lis kev cai nruab nrab hauv kev kuaj kab mob ntshav.
Muaj ob peb txoj kev hluavtaws rau Nws. Peb yuav sau ob zaug ntxiv rau kev piav qhia.
1. Kub 50g ntawm o-sulfonylbenzoic anhydride thiab 70g phenol kom yaj lawv. Ntxiv 50g ntawm anhydrous zinc chloride thiab hnov mob ntawm 135 ~ 140 degree rau 7 teev. Tom qab cov tshuaj tiv thaiv, ncuav cov reactant rau hauv dej kub thiab do sai sai rau disperse cov khoom crystalline kom txog thaum tsis muaj phenol tsw. Los yog chav distillation kom tshem tawm cov phenol seem. Cov khoom siv crystalline yog sib cais los ntawm kev pom, thiab cov khoom nyoos yog tau los ntawm kev ntxuav kom huv nrog dej. Cov khoom ntuj tuaj yeem yaj nrog 10 feem pua dilute alkali, lim, thiab tom qab ntawd tshuaj xyuas cov kua qaub kom tau txais nws.
2. (1) ntxiv 500g ntawm crude phthaloylsulfonyl anhydride, 700g ntawm phenol, thiab 500g ntawm anhydrous zinc chloride rau hauv 5000ML peb-chaw nres nkoj hwj, kub me ntsis kom yaj cov phenol, thiab kub thiab do ntawm 130135 degree rau 34 teev. Yog tias muaj npuas dej, ntxiv ob peb tee ntawm ethanol. Txias nws ua ntej, ces sov nws yog tias cov npuas tsis ploj. Tom qab cov tshuaj tiv thaiv, do nws los ntawm ib lub sij hawm mus rau disperse cov khoom;
(2) ncuav cov khoom rau hauv 5000ML beaker thaum nws kub, ntxuav lub khob nrog dej sov (3040 degree), lim thiab crystallize, thiab ntxuav ob zaug nrog dej;
(3) hloov cov av mus rau lub beaker, ntxiv 2000ml ntawm 10 feem pua sodium carbonate tov, cua sov rau 2 feeb, ib qho chaw rau 5 feeb, lim, thiab ces ntxuav nrog dej ob zaug;
(4) maj mam do cov filtrate thiab ntxiv rau dilute hydrochloric acid (200ml concentrated hydrochloric acid thiab 300ml dej). Nyob rau hauv cov ntaub ntawv ntawm ua npuas ncauj, ua kom sov nws pib, kub rau 6080 degree, txias nws, lim thiab sau cov sediment, ntxuav nws nrog dej ob zaug, thiab qhuav nws. Qhov tau. Nws yog cov hmoov liab nrog cov txiaj ntsig ntawm 450550g.
Nws yog tsuas yog siv los ua cov kua qaub-puag qhia thiab reagent rau kev kuaj lub siab ua haujlwm thiab chromatographic tsom xam. Nws yog ib hom ntawm acid-base qhia. Cov kua qaub-puag tes feem ntau yog hais txog ib yam khoom uas hloov xim nrog kev hloov ntawm pH tus nqi ntawm cov tshuaj. Nws yog ib qho tseem ceeb ntawm cov tshuaj uas tsis tseem ceeb hauv kev tshuaj xyuas tshuaj. Qhov kev hloov xim no tshwm sim los ntawm cov qauv kev hloov pauv ntawm "tautomer." Nws yog dav siv los ua tus ntsuas acid-base. Nws yog feem ntau siv rau hauv kev kuaj mob ntawm lub raum ua haujlwm. Nws cov ntsev monosodium yog siv los ntawm kws kho tsiaj rau kev kuaj lub raum, chromatography reagents, thiab lwm yam, thiab tseem tuaj yeem siv los txiav txim siab tag nrho cov pa roj carbon dioxide hauv cov ntshav, qhov taw qhia ntawm disaccharide hlau urea kab lis kev cai nruab nrab, thiab lwm yam.
Phenol liabmuaj zog corrosive rau ntawm daim tawv nqaij thiab mucous daim nyias nyias, inhibiting lub hauv paus paj hlwb los yog ua rau lub siab thiab lub raum ua haujlwm. Mob lom lom: nqus tau cov pa ntau ntau yuav ua rau mob taub hau, kiv taub hau, qaug zog, tsis pom kev tsis pom kev, pulmonary edema, thiab lwm yam. Kev noj los ntawm kev ua yuam kev tuaj yeem ua rau mob plab, kub hnyiab, phenol tsis hnov tsw hauv exhalation, ntshav ntuav lossis quav, ua rau plab hnyuv perforation. , poob siab, pulmonary edema, siab lossis raum puas, mob raum tsis ua haujlwm, thiab tuag los ntawm kev ua pa tsis ua haujlwm. Qhov muag qhov muag yuav ua rau kub hnyiab. Cov tawv nqaij kub hnyiab tuaj yeem nqus tau nws thiab ua rau mob raum tsis ua haujlwm tom qab qee lub sijhawm incubation. Cov tshuaj lom neeg mob ntev: tuaj yeem ua rau mob taub hau, kiv taub hau, hnoos, anorexia, xeev siab, ntuav, thiab proteinuria thaum mob hnyav. Nws yuav ua rau dermatitis. Nyob rau hauv rooj plaub ntawm ib qho ntawm cov xwm txheej saum toj no, kev kho mob yuav tsum tau ua tam sim ntawd. Kev sib cuag ntawm daim tawv nqaij: tam sim ntawd tshem tawm cov khaub ncaws tsis huv, so nrog glycerin, polyethylene glycol, los yog polyethylene glycol thiab cawv sib tov (7: 3), thiab ntxuav kom huv si. Los yog yaug nrog cov dej ntws loj rau tsawg kawg 15 feeb. Nrhiav kev kho mob. Kev sib cuag qhov muag: tam sim ntawd rub daim tawv muag thiab ntxuav lawv kom huv si nrog dej ntau, cov ntaub ntawv tshuaj, lossis cov tshuaj ntsev ib txwm tsawg kawg 15 feeb. Nrhiav kev kho mob. Inhalation: sai sai tawm ntawm qhov chaw mus rau qhov chaw uas muaj huab cua ntshiab. Ua pa ua pa kom tsis txhob muaj kev cuam tshuam. Yog ua pa nyuaj, muab cov pa oxygen. Yog tias ua tsis taus pa, muab kev ua pa tawm tam sim ntawd. Nrhiav kev kho mob. Noj: tam sim ntawd haus 15 ~ 30ml roj zaub. Induce ntuav. Nrhiav kev kho mob.
