The procedure for the preparation of propargylated kraft pulp fibers (KFT-Pr), was based on Faugeras et al.,22 (link) with some modifications to reaction conditions. The reaction time and the volume of propargyl bromide were increased. 76 mL (0.640 mol) of propargyl bromide was added to 1 L of an alkaline suspension of fibers (20 g, 124 mmol). The reaction medium was placed under mechanical stirring at room temperature. After 96 h, the mixture was diluted with 2 L of deionized water, let to rest for 4 h, filtered and washed with 2 × 1 L of hot water and 1 L of hot ethanol.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
