Suberinic acids are a type of
naturally encountered in the
Tree bark of
Betula tree species. Chemically, they predominantly have long (C18) chains with α- and ω- bifunctional saturated and unsaturated
fatty acid ends.
Their name originates from
suberin, a major chemical biopolymer of
tree bark.
Uses
The outer bark of birch (
Betula spp.) tree is abundant in
betulin. Upon extracting betulin, the remaining material consists of tissues containing
suberin. Suberin is a biopolyester composed of α,ω - bifunctional fatty acids, namely the suberinic acids, which, along with lignocarbohydrate complexes, can serve as a potential adhesive in the form of a byproduct obtained during the extraction of suberinic acids for polyol synthesis. Recent studies have proved the potential application of this product, obtained by depolymerizing suberin, in the wood-based panels such as
particleboard utilizing different
.
Recently, suberinic acids have found to have new applications in wood industry. The industrial mixture of suberinic acids, obtained from extracted birch outer bark, can be successfully used in industry for adhesion purposes, possibly in wood protection as well.[ Suberinic acid from birch bark and its suitability in wood protection, by A.
