Static and dynamic experiments were used to evaluate scale inhibition performance of polyaspartic acid derivative (PASP-SEA-ASP). The static experiments showed that the PASP-SEA-ASP had good scale inhibition performance and the scale inhibition rate exceeded 80% when the PASP-SEA-ASP was 2 mg•L-1 and the solution temperature was 40 OC. In the dynamic experiments, almost no scale formed on the heat transfer surface and the fouling thermal resistance decreases extraordinarily with PASP-SEA-ASP treatment experiment compared with the experiment without treatment. The PASP-SEA-ASP could be used in industrial cooling water systems.

An environment-friendly and multifunctional agent for industry circulation cooling water, polyaspartic acid derivatives with dihydroxyl group(DHPAP) was synthesized in aqueous solution. The FTIR spectrum of DHPAP was analyzed. Static experiments were carried out to validate scale inhibition performance of DHPAP. The scale inhibition ratios exceed 90% when 8 and 10 mg/L DHPAP under solution temperatures of 80 and 60°C, respectively. The scale inhibition ratios increase by increasing the DHPAP concentration with 6 and 8 mg/L under heating times of 10 and 6h, respectively. And the scale inhibition ratios are over 90%.

Intermediate vector polysuccinimide (PSI) was prepared by polymerization of malefic acid and ammonia at 180°Cin this article. Hydrophilic polyaspartic acid (PASP) derivative was prepared from amino-sulfonic and PSI; Lipophilic PASP derivative was prepared from PSI and diisopropylamine. Their scale inhibition rates of calcium carbonate were evaluated by static scale experiments. The inhibition rate of calcium carbonate was 90.2% when n(amino-sulfonic): n(PSI) =1:14 and the dosage of pharmaceutical was 12mg / L. The inhibition rate of calcium carbonate was 87.6% when n(diisopropylamine):n(PSI)=1:8 and the dosage of pharmaceutical was 15mg /L. The calcium carbonate that collected from static state experiments was analysised by scanning electron microscope (SEM). The results showed that polyaspartic acid derivatives were synthesized which had the best overall performance when n (amino-sulfonic): n (PSI) = 1:14.
