摘要
Procedure for the acetalacion of sepiolites and atapulguitas by reaction with aldehydes. Is the dispersion of sepiolite or tapulgita in an Inert Organic Solvent, such as benzene, and heating to boil until it is absorbed and produces the separation of Water of Crystallization.Then add a acetalacion as Catalyst, P - toluene sulfonic acid - and an aldehyde rcho formula in which R is a saturated or unsaturated radical; if R is unsaturated Radicals is added as an inhibitor, hydroquinone, and continue the boiling for about 1 h Now after the separation of produced water azeotrope.The Clay is filtered, washed and dried in vacuum with aceton. These materials have applications as fillers in Polymers.
