Taw qhia
4-Chloro-4′-hydroxybenzophenone yog cov organic compound. Cov hauv qab no yog cov ntaub ntawv hais txog cov khoom, kev siv, kev npaj, thiab kev nyab xeeb ntawm cov compound:
Zoo:
Cov tsos mob: 4-Chloro-4′-hydroxybenzophenone yog dawb crystalline lossis crystalline hmoov.
Solubility: soluble hauv ethanol, dimethylformamide thiab chloroform, me ntsis soluble hauv ether thiab carbon chloride.
Siv:
4-Chloro-4′-hydroxybenzophenone tuaj yeem siv los ua ib qho nruab nrab hauv cov organic synthesis rau kev sib txuas ntawm lwm cov organic sib txuas.
Txoj kev:
4-Chloro-4′-hydroxybenzophenone tuaj yeem tau los ntawm kev hloov ntawm sodium sulfite nrog sodium thiothioreagent (xws li phthathiadine) ntawm sodium sulfite. Txoj kev npaj tshwj xeeb yog raws li hauv qab no:
Lub phthamethamidine yog yaj nyob rau hauv dimethylformamide, hydroxyacetophenone yog ntxiv rau cov tshuaj tiv thaiv, tom qab ib tug tej lub sij hawm ntawm cov tshuaj tiv thaiv, dej ntxiv, thiab cov khoom yog muab rho tawm, qhuav thiab crystallized nrog chloroform kom tau lub hom phiaj cov khoom.
Cov ntaub ntawv kev nyab xeeb:
4-Chloro-4′-hydroxybenzophenone yog qhov ruaj khov nyob rau hauv cov xwm txheej dav dav. Txawm li cas los xij, kev sib cuag nrog cov neeg muaj zog oxidizing yuav tsum zam.
Cov cuab yeej tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav, thiab hnav ris tsho yuav tsum hnav thaum ua haujlwm li no.
Nws yuav tsum tau khaws cia kom deb ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, thiab khaws cia rau hauv lub thawv airtight kom tsis txhob raug huab cua.
Thov pov tseg ntawm qhov sib xyaw thiab nws cov pov tseg kom raug, ua raws li cov cai tswj kev pov tseg hauv zos.
