EARLIER investigations have demonstrated that di-cyandiamide (DCDA), the dimer of cyanamide, can successfully promote the dehydration condensation of: (1) glucose and orthophosphate to give glucose-6-phosphate; (2) adenosine and orthophosphate to give adenosine-5'-monophosphate; (3) orthophosphate to give pyrophosphate; (4) alanine to give alanylalanine and alanylalanylalanine. These reactions were carried out in dilute aqueous solutions in the dark. (It was also demonstrated that the combination of ultra-violet light and dicyandiamide could promote the synthesis of dipeptides. This observation has since been confirmed by other investigators.) These experiments were designed to demonstrate one possible means by which such compounds could have been formed on the prebiotic Earth, thus providing materials needed for the origin of living systems. Dicyandiamide itself could have been, present on the primitive Earth as was demonstrated with the ultra-violet irradiation of cyanide solution.

The Separations Research and Development Program consists of five identifiable activities in four general areas of effort. The five activities are: Chemical processes (Current processes and Innovations and new business); Chemical safety; Process equipment and control (equipment and instrument development); and By-products (recovery and purification). The proposed levels of funding for each of the five activities are listed. For each activity, the major accomplishments of the last year are listed, together with the proposed goals for the next two years. Significant trends in the program are noted.
