Abstract
The rate of reaction of Scots pine (Pinus sylvestris) with n-butyl isocyanate was followed by measuring weight percent gain (WPG) as a function of time (t). A model was developed to predict the form that an equation representing the WPG versus t ‘reaction profile’ might take. A curve of that form was fitted to the data using standard commercial software. The resulting ‘whole wood’ integrated rate equation was split into its component equations to yield information about the rate and extent of reaction in the lignin and holocellulose fractions of the wood. Assignment of equations, based on defined assumptions, indicate that in the initial stages of the reaction lignin reacts faster and to a higher degree of substitution than the holocellulose.This publication has 1 reference indexed in Scilit:
