Abstract
The present invention generally relates to the formation of organic gels by dissolving organic gelling agents in organic solvents. The aryl cyclohexanol gelling agents employed in this invention are not structurally related to previously known gellation agents and they exhibit potent gellation activity, for example, from 0.2-5%, by weight, of gelling agent is able to immobilize a variety of organic solvents. The gels formed range from optically transparent to slightly translucent, and complete fluidity can be restored by either increasing the temperature (reversible) or by chemical treatment (irreversible).

A method for gelling an organic liquid comprising:
- dissolving an effective amount of trans-1-phenyl-4-tert-butylcyclohexanol, trans-1-(para-fluorophenyl)-4-tert-butylcyclohexanol, or trans-1-(pentafluorophenyl)-4-tert-butylcyclohexanol in an organic liquid and cooling resultant mixture to form a gel.
A method for gelling an organic liquid comprising:
- dissolving an effective amount of trans-1-phenyl-4-tert-butylcyclohexanol in an organic liquid;
- and
- cooling the resultant mixture to form a gel.
A gel comprising a trans-1-phenyl-4-tert-butylcyclohexanol, trans-1-(para-fluorophenyl)-4-tert-butylcyclohexanol, or trans-1-(pentafluorophenyl)-4-tert-butylcyclohexanol agent and an organic liquid capable of dissolving said agent.
A gel comprising a trans-1-phenyl-4-tert-butylcyclohexanol agent and an organic liquid capable of dissolving said agent.
A method of gelling a first organic liquid incapable of dissolving an aryl cyclohexanol gelling agent but miscible with a second organic liquid capable of dissolving said agent, the method comprising:
- dissolving an effective amount of trans-1-phenyl-4-tert-butylcyclohexanol, trans-1-(para-fluorophenyl)-4-tert-butylcyclohexanol, or trans-1-(pentafluorophenyl)-4-tert-butylcyclohexanol gelling agent in a second organic liquid;
- mixing this solution with a first organic liquid;
- and
- cooling the resultant mixture to form a gel.
