- Abstract
The main objective of the present work was to synthesize a new type of rosin-based dispersant for Chinese Shenhua coal-water slurry (CWS) and evaluate it’s application performances for CWS preparation. In this study, 1.0 generation polyamidoamine (PAMAM) dendrimer with a dehydroabietylamine core, firstly was prepared through Michael addition and amidation, then the rosin-based dispersant was synthesized by the reaction of the dendrimer and chloroactic acid. The formulation and static stability of the slurry with the dispersant were investigated. The experimental results show that the rosin-based dispersant has a good dispersing ability at low dosage, and that the CWS with the dispersant exhibits the excellent static stability. Based on the above, the rosin-based dispersant is a promising dispersant for highly-loaded CWS in the practical use in industry.
