摘要：C.I. pigment red 170 is an important type of organic pigment. A new type of quaternary ammonium salt containing siloxane group was prepared and then used as a favorable dispersant in the surface treatment of pigment red 170. The quaternary ammonium salt was achieved from the reaction of N-(beta-aminoethyl)-gamma-aminopropyl-methyl-bimethoxy-silane and 3-chloro-2-hydroxypropyl-bimethyl-hexadecyl ammonium halide in isopropanol, and its structure was characterized by IR and NMR techniques. The flowability, dispersing extent, particle size, and wetting behaviors of pigment were determined and the results showed that a small amount of the above dispersant could bring to the high flowability, good dispersing stability, small particle size and excellent wettability of pigment red 170. We also proposed the scenarios of dispersing process of pigment red 170 based on the information obtained from above characterizations. (C) 2008 Elsevier B.V. All rights reserved.
