NC-608 2-Acrylanmido-2-methylpropanesulfonic acid (AMPS)
(1) Molecular Weight of NC-608:
M=207.25 C7H13NSO4 
CAS:15214-89-8
(2) Properties of NC-608:
It is a strong acid. Its pH depends on its concentration in water solution. The sodium salt in water is neutral. At 25 0C, 100 grams of water can dissolve 150 grams of this product, while 100 grams of Dimethylfomamide (DMF) can dissolve more than 100 grams of this product. The maximum solubility rate of 30% Ethanol solubility is 30%. Other solvents have small solubility to this product. It is easy to absorb water. Dry AMPS in room temperature is stable, and it is not possible for auto polymerization, but in aqueous solution it is very easy for auto polymerization. It is very slow to dissolve in water solution. The sodium salt solution of this product will not dissolve within one month when pH value is 9.
(3) Property of NC-608:
This product is homopolymers or acrylic acid copolymer low molecular weight polyelectrolyte. By far, it is the best dispersant among all anti-scaling dispersants in water treatment industry to prevent calcium phosphate, calcium carbonate, zinc salt, iron and slime.
As a stuff in textile, when added into synthetic fibers, it can improve the moisture absorption of fabrics because of sulfonic groups. The homopolymerization and copolymer of this product can improve the oil flow condition in oil wells and improve the productivity.
