Kodi katundu ndi ntchito zazikulu za rongalite ndi ziti?

Dzina: Sodium formaldehyde sulfoxylate;Rongalite C apezeka;Rongalite dihydrate;

Sodium bisulfoxylate formaldehyde; sodium hydroxymethane sulfinate

Mapangidwe a maselo: NaHSO2-CH2O-2H2O

CAS No.:149-44-0/6035-47-8

Katundu: Imadziwikanso kuti sodium formaldehyde bisulfate (rongalite).

Rongalite ufa translucent woyera rhombohedral makhiristo kapena tiziduswa tating'ono.

Kachulukidwe wowoneka 1.80-1.85g/cm3. malo osungunuka 64 ℃ (kusungunuka m'madzi ake a crystalline). Kuwola pamwamba pa 120 ° C.

Momasuka sungunuka m'madzi, pang'ono sungunuka mowa.

Mchere wa anhydrous ndi wokhazikika. Komabe, imawola pang’onopang’ono mu mpweya wonyowa. Kuchepetsa kwambiri kutentha kwambiri.

Njira yopangira masitepe atatu ya ufa wa rongalite imakhala ndi ufa wa zinc ndi madzi kuti apange slurry,

perekani mu sulfure dioxide kuti muyambe kupanga zinc dithionite, kenaka onjezerani formaldehyde,

Zinc ufa kuchepetsa ndiyeno amachita ndi sodium hydroxide kupanga.

Njira yatsopano yopanga njira imodzi imagwiritsa ntchito sodium metabisulphite ngati zopangira

ndipo imatsirizidwa mu sitepe imodzi mwa kuchepetsa ufa wa zinki ndi kuwonjezera kwa formaldehyde.

Amagwiritsidwa ntchito ngati chojambulira komanso chochepetsera kusindikiza ndi utoto,

kupanga mphira, kupanga shuga,

zopangira utoto wa indigo ndi kuchepetsa utoto.

Sodium formaldehyde sulfoxylate yogulitsidwa ndi Rongda Chemical imapangidwa pogwiritsa ntchito njira yatsopanoyi.

Ndi zabwino zotsatirazi:

zotsika kwambiri za heavy metal

perekani ntchito yabwino kwambiri ikatha kugulitsa

mbiri yapamwamba pamunda wamankhwala
