Abstract

The solubilities of 93%, 62%, and 5% dialdehyde starch in 0.5% and 1.0% sodium hydroxide; 0.5%, 1.0% and 5.0% borax; and in 0.5%, 1.0% and 5.0% sodium acetate solutions at 55°C for solution times of 15, 30, 60, and 120 minutes were determined as a part of an overall study of DAS-wheat gluten reaction products designed for adhesives. A method for determining the DAS content of solutions from apparent densities was developed. The results indicate that while any dilute inorganic alkaline solution will probably dissolve DAS the choice of reagent will depend upon what is desired in solution time, chain length of the DAS in solution, and viscosity of the solution.
