  • Single step creosote/borate wood treatment
    Patent number: 10137594
    Abstract: Disclosed is a method of reducing insect and microbial decay in wood. The method comprises the steps of: a) immersing the wood in a treatment solution comprising i) a C1-C6monoalkanolamine ester of boric acid (e.g., monoethanolamine ester of boric acid) and ii) creosote; and b) exposing the immersed wood from step a) to conditions which cause the release of boron from the C1-C6 monoalkanolamine ester of boric acid (monoethanolamine ester of boric acid) and which cause the boron to migrate into the interior of the wood.
