Polyacrylamide
Polyacrylamide
Molecular formular: [CH2CH(CONH2)]n
Molecular weight: 71.0785
CAS No: 9003-05-8
EINECS : 610-700-3
Physicochemical Properties:
Polyacrylamide,addreviation PAM,is a glassy solid,apt to water absorbing;the speed of absorbing water varies with different derivative ions.It is soluble in water and organic solvents as acetic acid,glycol,glycerin and amine.It will dissolve after long time heating.Dissolving temperature is over 120οC.It carbonates to black powder at 210οC.It carbonates to black power at 210οC without oxygen.
It could be made to four series,e.g.,non-ion,cation,anion and mixed cation & anion.
Applications and Usages:
It is an important water-soluble compound with the properties of flocculation,thickening,cut-resisting,block-reducing dispersing,etc..These properties vary with different derivative ions.So it is widely used in the field of oil extraction,mining selection,coat washing, metallurgy, chemical, papermaking,sugarrefining,pharmaceutical,environment protection,construction materials and agriculture.
Attention to Storage & Transport
No toxicity itself unless over 5‰ is absorbed that will do harm to stomach. The remains of PAM are poisonous.Strictly control the dose in food.Avoid moisture in storage & transport.
