Hydrazinium hydroxide tov (CAS # 10217-52-4)
zoo
Hydrazine hydrate yog xim tsis muaj xim, pob tshab, oily kua nrog lub teeb ammonia tsw. Hauv kev lag luam, cov ntsiab lus ntawm 40% ~ 80% hydrazine hydrate aqueous tov lossis hydrazine ntsev feem ntau yog siv. txheeb ze ntom ntom 1. 03 (21 ℃) ； Melting point – 40 ° C; Kub taw tes 118.5 ° C. Surface nro (25°C) 74.OmN/m, refractive index 1. 4284, heat of generation – 242. 7lkj/mol, flash point (qhib khob) 72.8°C. Hydrazine hydrate muaj zog alkaline thiab hygroscopic. hydrazine hydrate kua muaj nyob rau hauv daim ntawv ntawm dimer, miscible nrog dej thiab ethanol, insoluble nyob rau hauv ether thiab chloroform; Nws tuaj yeem ua rau iav, roj hmab, tawv, cork, thiab lwm yam, thiab decompose rau hauv Nz, NH3 thiab Hz ntawm qhov kub thiab txias; Hydrazine hydrate yog qhov txo qis heev, ua rau muaj kev kub ntxhov nrog halogens, HN03, KMn04, thiab lwm yam, thiab tuaj yeem nqus C02 hauv huab cua thiab tsim cov pa taws.
Txoj kev
Sodium hypochlorite thiab sodium hydroxide yog tov rau hauv ib qho kev faib ua feem, urea thiab ib tug me me ntawm poov tshuaj permanganate yog ntxiv thaum stirring, thiab oxidation cov tshuaj tiv thaiv yog nqa tawm ncaj qha los ntawm chav cua sov rau 103 ~ 104 ° C. Cov tshuaj tiv thaiv yog distilled, fractionated, thiab nqus cov concentrated kom tau 40% hydrazine, thiab ces distilled los ntawm caustic soda lub cev qhuav dej thiab txo siab distillation kom tau 80% hydrazine. Los yog siv ammonia thiab sodium hypochlorite ua raw khoom. 0.1% pob txha kua nplaum tau ntxiv rau ammonia kom inhibit qhov kev hloov pauv ntawm hydrazine. Sodium hypochlorite yog ntxiv rau cov dej ammonia, thiab cov tshuaj tiv thaiv oxidation yog nqa tawm nyob rau hauv lub zog stirring nyob rau hauv atmospheric los yog siab siab los tsim chloramine, thiab cov tshuaj tiv thaiv txuas ntxiv mus rau hydrazine. Cov tshuaj tiv thaiv yog distilled kom rov zoo ammonia, thiab tom qab ntawd sodium chloride thiab sodium hydroxide raug tshem tawm los ntawm qhov zoo distillation, thiab cov roj evaporation yog condensed rau hauv qis-concentration hydrazine, thiab tom qab ntawd sib txawv ntawm hydrazine hydrate yog npaj los ntawm fractionation.
siv
Nws tuaj yeem siv los ua cov kua nplaum tawg rau cov roj zoo fracturing kua. Raws li ib qho tseem ceeb zoo tshuaj raw khoom, hydrazine hydrate yog tsuas yog siv rau cov synthesis ntawm AC, TSH thiab lwm yam foaming agents; Nws kuj yog siv los ua tus neeg saib xyuas kev deoxidation thiab carbon dioxide tshem tawm ntawm boilers thiab reactors; siv hauv kev lag luam kws tshuaj los tsim cov tshuaj tiv thaiv kab mob thiab tshuaj tiv thaiv kab mob ntshav qab zib; Nyob rau hauv kev lag luam tshuaj tua kab, nws yog siv nyob rau hauv zus tau tej cov herbicides, cog kev loj hlob blenders thiab fungicides, insecticides, rodenticides; Tsis tas li ntawd, nws tuaj yeem siv rau hauv kev tsim cov roj foob pob hluav taws, roj diazo, roj hmab additives, thiab lwm yam. Nyob rau hauv xyoo tas los no, daim ntawv thov teb ntawm hydrazine hydrate tau nthuav dav.
kev ruaj ntseg
Nws yog tshuaj lom heev, muaj zog erodes ntawm daim tawv nqaij thiab thaiv cov enzymes hauv lub cev. Hauv kev mob hnyav heev, lub paj hlwb hauv nruab nrab tuaj yeem raug puas tsuaj, thiab feem ntau nws tuaj yeem ua rau tuag taus. Hauv lub cev, nws feem ntau cuam tshuam rau kev ua haujlwm metabolic ntawm carbohydrates thiab cov rog. Nws muaj cov nyhuv hemolytic. Nws cov vapors tuaj yeem ua rau cov mucous membranes thiab ua rau kiv taub hau; Irritates lub qhov muag, ua rau lawv liab, o thiab suppurated. Kev puas tsuaj rau daim siab, txo cov ntshav qab zib, lub cev qhuav dej ntawm cov ntshav, thiab ua rau cov ntshav tsis txaus. Qhov siab tshaj plaws tso cai ntawm hydrazine hauv huab cua yog 0. Img / m3. Cov neeg ua haujlwm yuav tsum tau txais kev tiv thaiv tag nrho, yaug ncaj qha nrog dej ntau tom qab daim tawv nqaij thiab qhov muag tau ntsib nrog hydrazine, thiab nug tus kws kho mob kom kuaj thiab kho. Qhov chaw ua haujlwm yuav tsum muaj qhov cua txaus thiab qhov concentration ntawm hydrazine nyob rau hauv ib puag ncig ntawm thaj chaw tsim khoom yuav tsum nquag saib xyuas nrog cov cuab yeej tsim nyog. Nws yuav tsum tau muab cia rau hauv qhov chaw txias, qhov cua thiab qhuav warehouse, nrog rau qhov kub thiab txias hauv qab 40 ° C, thiab tiv thaiv los ntawm tshav ntuj. Khaws kom deb ntawm hluav taws thiab oxidants. Thaum hluav taws kub, nws tuaj yeem tua nrog dej, carbon dioxide, ua npuas ncauj, hmoov qhuav, xuab zeb, thiab lwm yam.
