Scope

Main technical content: Project indicators: - Type I and Type II 2-acrylamido-2-methylpropane sulfonic acid (mass fraction)/% ≥ 99.0 ≥ 95.0 - Melting point/°C ≥ 185.0 ≥ 183.0 - Iron content (mass fraction)/mg/kg ≤ 5.0 ≤ 5.0 - Acid value/mg KOH/g 265-280 - Water content (mass fraction)/% ≤ 0.5 ≤ 0.5 - Color (Platinum-Cobalt scale)/Hazen units ≤ 20 ≤ 40 - Acrylamide a (content)/mg/kg -- Note 1: Type I is suitable for use in the production of high-molecular-weight polymers, such as flocculants and oilfield tertiary recovery agents. Note 2: Type II is suitable for use in fields with lower requirements for polymer molecular weight, such as the production of high-efficiency circulating water treatment agents. a: The content of acrylamide shall be determined through negotiation between the supplier and the customer if the client has special requirements.
