WebNov 20, 1992 · 1. A process for the production of a glycidyl ether of an aliphatic, cycloaliphatic or araliphatic primary or secondary alcohol, comprising: A) reacting epichlorohydrin with a molar excess of the alcohol in the presence of a Lewis acid catalyst; optionally. B) dehydrochlorinating the product so obtained; and. WebThe reaction of aldehydes and ketones with ammonia or 1º-amines forms imine derivatives, also known as Schiff bases (compounds having a C=N function). Water is eliminated in the reaction, which is acid-catalyzed and reversible in the same sense as acetal formation. The pH for reactions which form imine compounds must be carefully controlled. cardinali gabriela jesi https://ctmesq.com

WebPrimary amines undergo an addition reaction with the epoxide group to form a hydroxyl group and a secondary amine. The secondary amine can further react with an epoxide to form a tertiary amine and an additional hydroxyl group. Kinetic studies have shown the reactivity of the primary amine to be approximately double that of the secondary amine. WebIn the uncatalyzed reaction of epoxy groups with carboxyl groups four reaction products are to be expected6 (Eqs.1 to Eq.4). In the ring opening reaction of the epoxy group with a carboxyl group two different reaction products are formed. One is the ester of the primary hydroxyl group, and the second, the ester of the secondary hydroxyl group ... WebAt pH 3, the gel formation is complete within seconds, and the reaction rate can be tuned by modulating the pH. Rheology measurements show that the hydrogel properties can be tuned as a function of both the weight percent of solids in the gel and the denticity of amine cross-linker, allowing for predictable formation of gels with desired traits. cardinal jets
