Process flow of TETHMP·Na12
TETHMP·Na₁₂ is a highly phosphonated, multi-functional scale and corrosion inhibitor used in extreme conditions (high temperature, high hardness, oxidizing environments). Below is a step-by-step synthesis and formulation process flow. 1. Raw Materials Preparation Key Chemicals Required: Hexamethylenediamine (HMDA) – Primary amine source. Phosphorous acid (H₃PO₃) – Phosphonation agent. Formaldehyde (CH₂O, 37% solution) – Crosslinking agent. Sodium hydroxide (NaOH, 50%) – Neutralization/pH adjustment….
