A compound having the formula
A composition suitable as an additive in down-hole fluid for inhibiting clay swelling in a down-hole formation is comprised of an aqueous solution of a quaternary amine-based cationic polyelectrolyte and salt(s). The cation of the salt(s) may be a divalent salt cation, a choline cation, are certain ...
Novel metal-organic microporous materials are prepared in solution using mild reaction conditions from a metal or metalloid ion with a ligand containing multidentate functional groups in the presence of a templating agent. The resultant microporous materials are useful in the purification of liquids ...
In a papermaking process a paper product is formed from a mineral filler containing cellulosic slurry. Retention performance is provided by the sequential addition of a cationic charge-biasing species, an anionic flocculant, and then a certain microparticle. A shear stage is interposed between the f ...
