What is claimed is: 1. A process for preparing amide acetals represented in Formula I comprising dehydrating a reactant mixture comprising reactants selected from a group consisting of N-acyl dialkanol amines, O-acyl dialkanol amines and mixtures thereof wherein n and m are independently selected from the group of 2 or 3; p is 1, 2 or 3; R1 and R2 can be the same or different and are each independently selected from the group of hydrogen, a linear or branched alkyl, cycloalkyl or aryl group with 1-20 C atoms; R represents hydrogen, a branched or linear alkyl, cycloalkyl, aryl or an alkenyl group with 1-20 C-atoms, each may have one or more substituents. 2. The process according to claim 1, wherein the reactant mixture comprising reactants selected from a group consisting of N-acyl dialkanol amines, O-acyl dialkanol amines and mixtures therefrom is prepared by reacting at least one carboxylic acid and/or carboxylic acid ester and/or carboxylic acid anhydride and at least one dialkanol amine. 3. The process according to claim 2, wherein this process is combined directly with the dehydration process to form the bicyclic amide acetals of Formula I. 4. The process according to claim 2, wherein the dialkanolamine is selected from a group consisting of diethanol amine, diisopropanol amine, di-n-propanol amine or mixtures thereof. 5. The process according to claim 2, wherein the carboxylic acid is selected from a group consisting of lauric acid, isononanoic acid and mixtures thereof. 6. The process according to claim 1, wherein the temperature of the dehydrating reaction is in the range of 80�� C. to 250�� C. and the pressure of the dehydrating reaction is in the range of 13 to 101,325 Pa. 7. The process according to claim 1, wherein the temperature of the dehydrating reaction is in the range of 140�� C. to 230�� C. and the pressure of the dehydrating reaction is in the range of 133 to 1333 Pa. 8. The process according to claim 2, wherein the temperature of the reaction of the at least one carboxylic acid and/or carboxylic acid ester and/or carboxylic acid anhydride with the at least one dialkanol amine is in the range of 80�� C. to 250�� C. and the pressure in the range of 13,000 to 150,000 Pa. 9. The process according to claim 2, wherein the temperature of the reaction of the at least one carboxylic acid and/or carboxylic acid ester and/or carboxylic acid anhydride with the at least one dialkanol amine is in the range of 140�� C. to 230�� C. and the pressure in the range of 27,000 to 110,000 Pa.
