The mass balance of PUF acidolysis was obtained by comparing the total weight of gas, liquid, and solid products versus the starting weight of PUF and maleic acid. The overall yield of repolyol from PUF acidolysis after hydrolysis and purification was calculated based on the obtained neat repolyol versus the polyol content within the input PUF.

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.
