Dab tsi yog cov khoom thiab kev siv tseem ceeb ntawm rongalite?

Lub npe: Sodium formaldehyde sulfoxylate; Rongalite C lumps; Rongalite dihydrate;

Sodium bisulfoxylate formaldehyde; sodium hydroxymethane sulfinate

Cov mis mos molecular: NaHSO2-CH2O-2H2O

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

Khoom: Kuj hu ua sodium formaldehyde bisulfate (rongalite).

Rongalite hmoov translucent dawb rhombohedral muaju los yog daim me me.

Pom tseeb ceev 1.80-1.85g / cm3. melting point 64 ℃ (solved nyob rau hauv nws crystalline dej). Decomposes siab tshaj 120 ° C.

Dawb soluble hauv dej, me ntsis soluble hauv cawv.

Anhydrous ntsev yog ruaj khov dua. Txawm li cas los xij, nws maj mam decomposes hauv huab cua ntub. Muaj zog txo qis ntawm qhov kub thiab txias.

Cov txheej txheem peb-kauj ruam ntau lawm rau rongalite hmoov muaj zinc hmoov thiab dej los tsim cov slurry,

dhau mus rau hauv sulfur dioxide rau cov tshuaj tiv thaiv los tsim txawm zinc dithionite, ces ntxiv formaldehyde ntxiv,

zinc hmoov txo thiab tom qab ntawd hnov ​​​​mob nrog sodium hydroxide los tsim.

Cov txheej txheem tshiab ib-kauj ruam siv sodium metabisulphite ua raw khoom

thiab ua tiav hauv ib kauj ruam los ntawm kev txo cov zinc hmoov thiab ntxiv ntawm formaldehyde.

Nws yog siv los ua tus neeg sawv cev kos duab thiab txo tus neeg sawv cev rau kev luam ntawv thiab dyeing,

rau synthesis ntawm roj hmab, rau zus tau tej cov suab thaj,

rau zus tau tej cov indigo dyes thiab txo dyes.

Cov sodium formaldehyde sulfoxylate muag los ntawm Rongda Chemical yog tsim los siv cov txheej txheem tshiab.

Nrog rau qhov zoo hauv qab no:

cov ntsiab lus qis tshaj ntawm cov hlau hnyav

muab kev pabcuam zoo tshaj plaws tom qab muag
