Derivatives from Black Liquor as a Wood Preservant: A Review

Abstract

Increased concern with environmental issues, the health of operators of condoms and the consumers of wood, and the reuse of these treated woods after their use, has generated the need to develop less aggressive condoms treatments And the environment with sustainable principles. Thus, the aim of research has been to develop environmentally correct and effective products against the attack of biodeteriorating agents. One viable alternative containing interesting inhibiting properties is Tall Oil, which is a natural oil from, renewable-source. Tall Oil is a by-product of kraft pulp production. This byproduct is not a pure triglyceride compound, but a mixture of fatty acids, resin and unsaponifiable acids. The use of Tall Oil and its derivatives as a protective agent in wood has been considered promising. It can be used pure, whether crude or distilled; and also mixtures with efficient biocides, but leachable as boron. However research is still needed including the characterization of Tall Oil products, the determination of the protective agent and the environmental aspects.
