A condensation reaction is a reaction where two molecules join together and in doing so create a complex molecule and a much simpler molecule that is a byproduct of the reaction. The simple molecule eliminated can be water, ammonia, or an alcohol. The...

Dehydration synthesis is a chemical reaction in which one or more molecules of water are removed from the reactants to form a new product. These reactions can occur when one of the reactants has a hydroxyl group (OH) that can be cleaved, thus forming...

A condensation reaction is a chemical reaction in which two molecules or moieties combine to form one single molecule, together with the loss of a small molecule.[1] When this small molecule is water, it is known as a dehydration reaction; other...

In this paper, the chemorheological and dynamic mechanical behavior of melamine-formaldehyde (MF) resins of four different formaldehyde/melamine (F/M) molar ratios (1.25, 1.5 1.75 and 2.00) are Investigated. ME resins polymerize via a polycondensation reaction involving formation of up to 10 wt% of [H.sub.2]O on...

Acid catalyzed self-condensation reactions and NMR spectra of three model compounds for methylolated melamine-formaldehyde resins were studied. The model compounds had a single --N(H) [CH.sub.2] [OCH.sub.3] dyad, a single --N([[CH.sub.2] [OCH.sub.3]).sub.2] dyad, and three --N([[CH.sub.2] [OCH.sub.3]).sub.2] dyads. Evidence...
