Abstract
Stable, thermally reversible gels of organic solvents and a gelling agent having the formula R.sub.1 --(CH.sub.2).sub.n --CO.sub.2 --R.sub.2 wherein R.sub.1 is an anthracene analogue or substituted anthracene analogue, n is zero or a whole number from 2 to 20, and R.sub.2 is cholesteryl and cholestanyl or a derivative of cholesteryl or cholestanyl, processes for producing same, and novel anthracene analogue cholesteryl and cholestanyl esters and derivatives.
Claims18
A gelled organic solvent comprising a solvent selected from the group consisting of alkanes, alkenes, alkanols, aldehydes, acids, esters, and amines, in combination with a gel-producing amount of a compound having the formula (I)
- R.sub.1 --(CH.sub.2).sub.n --CO.sub.2 --R.sub.2 (I)
- wherein n is zero or a whole number between 2 and 20, R.sub.1 is an anthracene analogue or substituted anthracene analogue, and R.sub.2 is selected from the group consisting of cholesteryl, cholestanyl, and their derivatives.
A process for producing a gelled organic solvent comprising mixing said organic solvent with a gell producing amount of a gelling agent having the formula
- R.sub.1 --(CH.sub.2).sub.n --CO.sub.2 --R.sub.2,
- wherein n is zero or a whole number between 2 and 20, R.sub.1 is an anthracene analogue, and R.sub.2 is selected from the group consisting of cholesteryl, cholestanyl, and their derivatives.
