Additive for coal-water slurry |
| abstract |
PURPOSE: To provide the subject additive containing a partially esterified product of a specific styrene/maleic acid copolymer, capable of stably dispersing coal powder in water at high concentration to form a dispersion having high fluidity and effective for suppressing the abrasion of especially a transportation pipe and a burner tip. n CONSTITUTION: The objective additive contains a partially esterified product of a styrene/maleic acid copolymer produced by reacting (A) a styrene/maleic anhydride copolymer expressed by formula I ((l) is integer of 1-5; (m) is integer of 1-3; (n) is integer of 4-10), (B) a polyether derivative having a polyalkylene glycol chain and expressed by formula II (X is residue of a 1-4C compound having one active hydrogen atom; R is 3-8C alkylene oxide; (p) is integer of 0-10; (q) is integer of 10-200) and (C) a ≥6C primary amine at molar ratios (A:B:C) of 1:(1-10):(1-3). n COPYRIGHT: (C)1992,JPO&Japio |
