Abstract
A process for the production of carbohydrate-phenolic resins wherein a phenolic compound is reacted with a hexose saccharide in the presence of a Lewis acid catalyst to form a solid fusible resin which is curable with cross linking agents, such as hexamethylenetetramine.
Claims13
A process for producing a carbohydrate-phenolic resin comprising reacting
- 1. dextrose or a carbohydrate which hydrolyzes to form dextrose, and
- 2. a phenolic compound having the formula ##STR6## wherein R is selected from the group consisting of C.sub.1 to C.sub.3 alkyl, C.sub.1 to C.sub.3 alkoxy, halogen, hydroxy and hydrogen, in the presence of a metal salt Lewis acid catalyst to form a solid, fusible resin, and separating the resin from the reaction mixture.
