Xwm:
Dawb crystalline hmoov, tau los ntawm crystallization los ntawm aqueous ethanol. Lub melting point yog 153 degree thiab pib decompose thaum dissolution. Soluble hauv dej heev, pH ntawm 1% aqueous tov yog 7.4. Yuav luag insoluble hauv cawv, ethers, chloroform, thiab benzene. Reacts nrog hydrochloric acid, sulfuric acid, oxalic acid, phosphoric acid, thiab nitric acid los ua ntsev. Cov tshuaj chlorides tsim tawm yog cov dej soluble hauv dej, thaum cov sulfates thiab oxalates tsuas yog me ntsis soluble hauv dej, thaum phosphates thiab nitrates tsis tuaj yeem crystallize. Nyob rau hauv lub xub ntiag ntawm nitrite, carbazide yuav hloov mus rau hauv heev tawg carbonyl azide tebchaw. Cov tshuaj aqueous ntawm carbazide yuav maj mam decompose thaum rhuab ua ke nrog acid los yog hauv paus.

Lub hom phiaj:
Carbohydrazide tuaj yeem siv los ua deoxidizer rau boiler dej hauv kev kho dej, thiab kuj yog tus neeg sawv cev passivation rau cov hlau qhov chaw kom txo tau qhov corrosion ntawm cov hlau. Carbohydrazide tuaj yeem hnov ​​​​mob nrog cov pa oxygen hauv dej los tsim cov pa roj carbon dioxide, nitrogen, thiab dej. Thaum siv, hmoov carbazide tuaj yeem ncaj qha ntxiv rau dej lossis nws cov kua dej tuaj yeem siv tau. Nws tuaj yeem siv ib leeg lossis ua ke nrog redox catalysts xws li hydroquinone lossis lwm yam quinones, nrog rau cobalt complexes. Qhov ntsuas kub tsim nyog rau carbazide yog 87.8 ~ 176.7 degree, uas txhais tau tias nws yog siv hauv qab qhov kub ntawm cov dej vaporization.

Txoj kev:
- Ua ntej, dissolve ntau tshaj ammonia thiab sodium cyanide hauv dej, thiab tom qab ntawd ntxiv cov pa roj carbon dioxide kom precipitate rau hauv hydrazine carbonate.
-Tom qab pom, ntxuav, thiab ziab, cov precipitate tuaj yeem tau txais cov ntshiab hydrazine carbonate.

Cov ntaub ntawv kev ruaj ntseg:
-Cov hmoov thiab kev daws ntawm hydrazine carbonate ua rau muaj kev pheej hmoo ntawm kev khaus thiab xeb rau lub qhov muag thiab tawv nqaij, thiab cov khoom siv tiv thaiv tus kheej tsim nyog yuav tsum tau hnav thaum siv.
-Nws yog ib qho tsim nyog yuav tsum tau ua haujlwm nyob rau hauv qhov chaw muaj cua zoo kom tsis txhob nqus plua plav lossis vapor.
-Tsis txhob sib cuag nrog cov muaj zog oxidants, acids, thiab lwm yam khoom los tiv thaiv kev txaus ntshai.
-Hydrazine carbonate yuav decompose thiab tsim cov pa phem thaum lub sij hawm cua sov, thiab yog tias tsim nyog, nws yuav tsum tau ua nyob rau hauv cov khoom tawg-pov thawj.
-Lub sijhawm khaws cia thiab tuav, cov kev cai ib puag ncig, kev noj qab haus huv, thiab kev nyab xeeb yuav tsum tau ua raws.
