WebDean Kenyon has examined the role of this chemical in reactions that can produce peptides. A co-worker then considered this reactive nature and examined the possible role dicyanamide may have had in primordial biogenesis . WebThe high current density reaction conditions based on industrial electrolysis for hydrogen production imply the presence of more active charge transfer, which also suggests that it is a great challenge to establish a suitable catalyst interface to promote charge transfer to the reaction intermediate. ...

WebThe curing reaction of dicyandiamide and epoxy resins has been extensively studied by a number of workers, 46, 192, 193 and most recently by Pascault et al. 194 In another thorough examination of the curing process Zahir 195 studied the reactions of both cyanamide and dicyandiamide. Webisothermal reaction heats calculated are listed in Table 2. It is clear that the curing heat increases with increasing the curing temperature. The reaction heats obtained are between 362.4 J/g and 410.5 J/g at different curing temperatures. This is due to the fact that a higher curing temperature can facilitate the dissolution of DICY, A D B C WebProduct name : Dicyandiamide Product Number : D76609 Brand : Aldrich CAS-No. : 461-58-5 1.2 Relevant identified uses of the substance or mixture and uses advised against ... 10.3 Possibility of hazardous reactions Violent reactions possible with: Strong oxidizing agents acids .
