Derivatives of polyether glycol esters of polycarboxylic acids as rheological additives for coal-water slurries |
摘要 |
Coal-water slurries containing a rheological additive are disclosed. The rheological additives employed for the preparation of the present coal-water slurries are ester products obtained from the reaction of a polycarboxylic organic acid with two or more hydroxylic compounds. Salts of these reaction products may also be employed. The rheological additive is employed in an amount from about 0.1 to about 4 percent by weight of the slurry, the slurry having from about 60 to about 80 percent by weight solids, the balance being water.
