Abstract
A dispersion of dibenzylidene sorbitol acetal (DBS) in an organic liquid selected from alkylene glycols and polyalkylene glycols is provided wherein the DBS has a moisture content of greater than 2 wt. %, to inhibit the dispersion from gelling prematurely.
Claims25
A pourable dispersion comprising a DBS compound dispersed in an organic liquid produced by the process of mixing from 10 to 40 wt. % of a DBS compound, said DBS compound having greater than 2 wt. % associated water and said water being sufficient to inhibit the dispersion from gelling, with an organic liquid capable of being gelled by the DBS compound, and said mixture forming a stable pourable dispersion of the DBS compound with the organic liquid for 24 hours at a temperature of 25.degree. C.
The composition of claim 6 wherein the DBS compound has greater than 2.4 wt. % associated water.
A composition comprising an organic liquid capable of being gelled, and 10 to 30 wt. % of a DBS compound dispersed in the organic liquid, wherein the DBS compound is selected from the group consisting of diacetals which are the condensation product of an two moles of an aromatic aldehyde selected from the group consisting of benzaldehyde and benzaldehyde having from 1 to 3 substituent groups selected from C.sub.1-4 alkyl, halogen, and C.sub.3-5 alkylene forming a carbocyclic ring with adjacent carbon atoms on an unsaturated hydrocarbon ring and one mole of a polyhydric alcohol selected from the group consisting of xyltiol and sorbitol, and the DBS compound is prepared by drying a slurry or filter cake of the DBS compound, having greater than 10 wt. % water, down to from 4 wt. % to greater than 2 wt. % associated water, and wherein the dispersion is pourable at 25.degree. C.
A method of making a pourable dispersion comprising the steps of dispersing from 10 to 40 weight % of a DBS compound, having greater than 2 weight % associative water and said water being sufficient to inhibit the dispersion from gelling, in an organic liquid capable of being gelled by the DBS compound, wherein the composition is a pourable dispersion for 24 hours at a temperature of 25.degree. C.
