Abstract
Liquid hydrocarbons are gelled by the introduction of a phosphate ester and a crosslinking agent. Gelling times and viscosities are improved through the use of an enhancer which is, preferably, an oxyalkylated amine or a blend of an oxyalkylated amine with another amine or a non-nitrogen-containing component. Preferred phosphate esters are ether phosphate esters.
