Studies on Novel Bisaryl hydrazino‐s‐triazine Derivatives

Abstract

Various 2-phenyloxy-4,6-bisarylhydrazino-1,3,5-triazines(3a-f) were prepared by reaction of 2- phenyloxy -4,6-dichloro -1,3,5-triazine and various aryl hydrazine derivatives. All the 3a-f derivatives were characterized by elemental analysis and IR spectral studies. All the compounds were screened for microbial activity against gram-positive and gram-negative bacteria.

Association of hard segments in gas separation through polyurethane membranes with aromatic bulky chain extenders

“…After drying, the product with melting point of 136-137 °C was obtained [43]. In the next step the product was reacted with excess hydrazine under reflux for 48 h [44,45]. Hydrazine was used as the reactant and also solvent in the second step of the reaction.…”

Elucidating the effect of chain extenders substituted by aliphatic side chains on morphology and gas separation of polyurethanes

“…The solid was collected and washed thoroughly with deionized water [42]. Excess hydrazine reacted with the product overnight under reflux as the second step [43,44]. Then the solid product was filtered and washed (Scheme 1).…”
