Experiment  § Development of Furan Prepreg Resin Furan resins can be produced from furfuryl alcohol (FA), which is extracted from agricultural waste such as corn cobs, making them an important material in the field of sustainable and green chemistry (Figure 1–2). After polycondensation, furan resins form a cross-linked network structure. Due to the inherent stability of the furan ring, these resins exhibit excellent resistance to acids, alkalis, solvents, and heat, and are commonly used as...

Experiment  § AT-710 Automatic Potentiometric Titrator Everwide has introduced an AT-710 automatic potentiometric titrator to enhance laboratory analysis efficiency and accuracy. This instrument is applied to the determination of Total Acid Number (TAN), Total Base Number (TBN), Epoxy Equivalent Weight (EEW), Hydroxyl Value (OH Value), and isocyanate group (–NCO) content (Figure 1). The AT-710 utilizes potentiometric titration for analysis. By monitoring changes in ion concentration in the...
