Hydrazine sulfateyog ntsev tsim los ntawm hydrazine thiab sulfuric acid. Cov mis mos molecular yog N2H4 · H2SO4. Nws yog xim tsis muaj xim thiab tasteless scaly siv lead ua los yog orthorhombic siv lead ua. Me ntsis soluble nyob rau hauv dej txias, yooj yim soluble nyob rau hauv dej kub, thiab cov aqueous kua yog acidic. Insoluble hauv cawv. Nws yog ruaj khov nyob rau hauv cov huab cua thiab tsis yooj yim rau nqus noo noo. Nws yog ib tug muaj zog txo tus neeg sawv cev. Nws yooj yim ua rau tawg thaum ntsib oxidant. Tsis txhob coexist nrog alkali thiab oxidant. Toxic thiab carcinogenic.
Dab tsi yog hydrazine sulfate siv rau?
1. Muaj lub luag haujlwm ntawm hydrazine sulfate:
Azodiisobutyronitrile, thiab lwm yam. Nws kuj tseem siv tau los ua tus neeg sawv cev txo qis, feem ntau yog siv los ua cov tshuaj reagent rau kev kho cov hlau saum npoo thiab kev tsom xam, thiab kuj yog rau kev ua kom huv ntawm cov hlau tsis tshua muaj.
2. Kev ua liaj ua teb ntawm hydrazine sulfate:
Siv ua tshuaj tua kab, tshuaj tua kab mob, thiab lwm yam.
3. Pharmaceutical teebmeem ntawm hydrazine sulfate:
Mob qog nqaij hlav hauv hlwb: Kev noj hydrazine sulfate thiab kws khomob tuaj yeem txhim kho cov tsos mob ntawm lub paj hlwb ntawm cov neeg mob qog noj ntshav. Nws kuj tseem tuaj yeem pab txo cov qog loj ntawm cov neeg uas muaj hom mob hlwb glioblastoma.
Kev poob phaus thiab nkim yog txuam nrog mob qog noj ntshav. Cov kev tshawb fawb thaum ntxov tau pom tias hydrazine sulfate tuaj yeem ua rau qhov hnyav poob ntawm qee cov neeg mob qog noj ntshav.
Hodgkin's disease (lymphatic cancer): qee qhov kev tshawb fawb tau pom tias hydrazine sulfate tuaj yeem ua rau qeeb ntawm kev loj hlob ntawm Hodgkin's disease.
Neuroblastoma (neuroblastoma): muaj pov thawj tias hydrazine sulfate tuaj yeem tiv thaiv kev loj hlob ntawm neuroblastoma.
4. Rau kev npaj Azodicarbonamide foaming agent:
Nws yog kom khov lub teeb hydrazine oxidation tov rau {{0}} ~ - 10 degree, lim thiab rov qab sodium carbonate decahydrate; Ntxiv 98 feem pua sulfuric acid dropwise mus rau diluted hydrazine oxidation tov tom qab recovering sodium carbonate decahydrate rau pH=1-3, thiab khov rau 0 ~ - 10 degree . Tom qab cov hydrazine sulfate tau sib cais tag nrho, lim nws thaum txias, thiab crystallization niam cawv yog siv los ua dej rau hydrazine synthesis thiab ob peb zaug. Thaum cov sodium chloride yog saturated thiab pib sib cais, sov lub concentrated niam cawv thiab lim nws thaum kub kom cais sodium chloride, ntxiv dej thiab cua sov kom yaj hydrazine sulfate, maj mam ntxiv urea tov, thiab ua condensation cov tshuaj tiv thaiv. Tom qab cov tshuaj tiv thaiv condensation tiav, txias cov kua pub, tom qab ntawd centrifuging lub biuret, cua sov thiab tsom rau cov kua dej condensation, txias thiab crystallizing kom tau txais ammonium sulfate crystals, thiab crystallization niam kua yog siv raws li urea dej faib.
Muaj nuj nqi pov thawj ntawm hydrazine sulfate:
Hauv xyoo 1970, nws tau tshaj tawm tias yog tshuaj kho mob qog noj ntshav thiab cachexia, tab sis xyoo 1990, nws tau pom tias tsis muaj txiaj ntsig rau ob yam kab mob. Ntawm qhov tsis sib xws, nws tau pom tias yog carcinogenic thiab lom, tshwj xeeb tshaj yog nyob rau lub sijhawm ntev.
Thaum ib tug neeg raug mob los ntawm kev mob qog noj ntshav lossis lwm yam kab mob, lub cev yuav raug kev ua haujlwm hu ua cachexia. Hauv cov txheej txheem no, lub cev pib poob qis thiab tus neeg mob yuav ntsib qhov hu ua pathological anorexia.
Rau mob qog noj ntshav, qhov no yog vim cov qog nqaij hlav cancer nqus cov piam thaj, uas yog hom qab zib uas muab lub zog rau lub cev. Nws yog ib qho khoom siv tsis zoo uas siv lub zog ntau dua li nws tsim.
Qhov no ua rau lub cev nqus tau cov as-ham ntxiv los ntawm cov rog ntau dhau. Qhov no ua rau kev tsim cov lactic acid, uas nkag mus rau hauv daim siab, uas nws hloov mus rau hauv cov piam thaj thiab siv los ntawm cov qog nqaij hlav cancer uas siv lub zog. Qhov no yog ib lub voj voog vicious uas ua rau poob qis ntxiv.
Dr. Joseph kub ntseeg hais tias hydrazine sulfate tuaj yeem kho cachexia thiab mob qog noj ntshav vim tias qhov sib xyaw no tau raug pov thawj los tiv thaiv lub siab los ntawm kev hloov lactic acid rau hauv qabzib.
Nws tau hais tias qhov no yuav nres cov txheej txheem cachexia thiab yuav ua rau cov qog noj ntshav zoo. Txawm li cas los xij, hauv kev sim tshuaj, hydrazine sulfate tsis ua rau muaj txiaj ntsig zoo rau cov neeg mob qog noj ntshav.
Raws li xyoo 2011, hydrazine sulfate tsuas yog siv hauv kev sim tshuaj. US Food and Drug Administration (FDA) tsis tau pom zoo rau kev siv kho mob, yog li cov kws kho mob tsis tuaj yeem sau cov tshuaj no.
Txawm hais tias hydrazine sulfate tsis tuaj yeem siv rau hauv kev kho mob qog noj ntshav, nws yog siv los ua tus neeg sawv cev foaming hauv kev lag luam tshuaj thiab siv los rho cov fibers los ntawm acetate fibers. Nws kuj tseem siv los ua cov tshuaj tua kab mob thiab fungicide.
Raws li nws cov ntaub ntawv kev nyab xeeb cov ntaub ntawv (MSDS), hydrazine sulfate muaj cov tshuaj tiv thaiv loj hauv tib neeg lub cev. Kev ntsuas kev noj qab haus huv thiab kev raug mob yog ob qho tib si 3 / 4, uas txhais tau hais tias cov tshuaj tiv thaiv yuav loj heev.
Kev sib cuag nrog hydrazine sulfate yog corrosive thiab tuaj yeem ua rau mob qog noj ntshav yog tias nqus tau, noj los yog tiv tauj nrog daim tawv nqaij. Raws li MSDs, nws muaj me ntsis flammability theem thiab ib nrab reactivity theem.
