Hydroxymethylfurfural and its Derivatives: Potential Key Reactants in Adhesives

Conversion of fructose into 5-hydroxymethylfurfural (HMF) and its derivatives promoted by inorganic salt in alcohol.

The conversion of D-fructose to 5-hydroxymethylfurfural (HMF) on a 1 mmol scale was achieved in good yield (68%) using NH(4)Cl as catalyst in isopropanol at 120°C. About 3% of 5-i-propoxymethylfurfural was formed. The reaction in ethanol at 100°C on a 10g scale gave a total yield of HMF and 5-ethoxymethylfurfural of 42%. No mineral acid such as H(2)SO(4) and HCl are required.

Introducing Potential Key Proteins and Pathways in Human Laryngeal Cancer: A System Biology Approach

The most common malignant neoplasm of the head and neck region is laryngeal cancerwhich presents a significant international health problem. The present study aims to screenpotential proteins related to laryngeal cancer by network analysis to further understandingdisease pathogenesis and biomarker discovery. Differentially expressed proteins were extractedfrom literatures of laryngeal cancer th...

Potential of carbohydrates for exterior-type adhesives

New exterior-quality adhesives for wood products need to be available if the cost or supply of phenol-based adhesives should become unfavorable. Carbohydrates represent a large, inexpensive, renewable resource from which to obtain polymerizable materials. Preliminary trials led to exploratory evaluation of a system in which carbohydrates and some urea replace as much as 35 percent of the phenol...
