Urea formaldehyde and Alkylated urea formaldehyde review paper

In preliminary studies of urea-formaldehyde reactions, the influence of the U:F molar ratio, the temperature and the catalyst were investigated. Subsequently, in a more rigorous evaluation of the influence of four variables on urea-formaldehyde resin formation, viz., U:F molar ratio, pH, temperature and reaction time, a set of twenty reactions were performed using a statistical approach. The results indicate that high resin viscosity is best achieved by using a high U:F molar ratio (2:1) and conducting the reaction at 90°C. Due to application of coating and paint urea formaldehyde resin blend with alcohol, oil So we have think about the alkylated urea formaldehyde resin but in low molecular weight alcohol create a problem during the separation of water from the product so we can use butanol as a use for production of alkylated urea formaldehyde resin. And finally we have to find out the kinetics of urea formaldehyde resin.
