Detailed modeling of the kraft pulping chemistry: carbohydrate reactions [PDF]

AIChE Journal, 2020
AbstractThe article introduces a detailed model for carbohydrate chemistry in kraft pulping. This article is continuation to the modeling work carried out for hot water extraction and chemical pulp bleaching. The model includes galactoglucomannan, xylan, and cellulose acid–base equilibria, in addition to peeling, stopping, and alkaline hydrolysis ...

Detailed Chemistry Studies of 225Actinium Labeled Radiopharmaceuticals

Current Radiopharmaceuticals, 2022
Background: The synthesis of 225Actinium derivatives was afforded by using PSMA- 617, DOTATATE peptides, and EDTMP ligand. Detailed experiments, quality control (QC), and stability studies were also well described. The radiolabelling reactions were performed in mild conditions with desirable radiochemical yields and high radiochemical purities ...
