3 4-Dihydroxybenzonitrile (CAS # 17345-61-8) Kev taw qhia

3,4-Dihydroxybenzonitrile yog cov organic compound. Nws muaj ob pawg hydroxyl thiab ib pab pawg hloov ntawm nitrile pawg.

Khoom: Nws yog soluble hauv qee cov kuab tshuaj organic xws li ethanol, ether thiab chloroform, insoluble hauv dej. Nws yog qhov ruaj khov hauv huab cua, tab sis tuaj yeem hnov ​​​​mob thaum ntsib cov oxidizing muaj zog.

Siv:
3,4-Dihydroxybenzonitrile feem ntau yog siv los ua ib qho nruab nrab hauv cov organic synthesis.

Txoj kev:
3,4-Dihydroxybenzonitrile tuaj yeem tau txais los ntawm kev txo p-nitrobenzonitrile. Txoj kev npaj tshwj xeeb yuav suav nrog cov tshuaj tiv thaiv ntawm p-nitrobenzonitrile nrog ferrous ions lossis nitrite kom txo tau nws los ua 3,4-dihydroxybenzonitrile.

Cov ntaub ntawv kev nyab xeeb:
3,4-Dihydroxybenzonitrile feem ntau muaj kev nyab xeeb rau kev siv raws li kev kuaj mob niaj hnub, tab sis cov hauv qab no yuav tsum raug sau tseg:
Tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag, thiab tsis txhob nqus cov plua plav lossis roj;
Cov cuab yeej tiv thaiv tus kheej yuav tsum tau hnav thaum lub sijhawm ua haujlwm, xws li cov hnab looj tes kuaj thiab tsom iav tiv thaiv;
Thaum nws siv lossis khaws cia, kev sib cuag nrog cov oxidants muaj zog thiab cov khoom siv hluav taws xob yuav tsum raug zam kom tsis txhob muaj kev phom sij txaus ntshai;
Khaws 3,4-dihydroxybenzonitrile rau hauv lub thawv airtight, kom deb ntawm hluav taws kub thiab kub.
