Process Improvement for High-Quality Palm Kernel Amidopropyl Betaine (PKAPB) from Splitted Palm Kernel Fatty Acid (SPKFA)
Description
This dataset supports the investigation of process parameters affecting the quality of palm kernel amidopropyl betaine (PKAPB), focusing on nitrogen gas flow rate and DMAPA (dimethylaminopropylamine) makeup ratio. The data includes measurements of acid number, viscosity, and color stability of PKAPB under various process conditions. The study found that nitrogen flow rate and DMAPA concentration significantly influence the quality of the final product. An increase in nitrogen flow rate improves the color stability of PKAPB by reducing oxidation, but it also results in higher acid numbers and increased viscosity, likely due to the stripping of DMAPA during the reaction. Conversely, increasing DMAPA content enhances amidation conversion, leading to lower acid numbers and more stable viscosity. The data identifies 100 mL/min as the optimal nitrogen flow rate and 30% DMAPA as the minimum effective concentration for high-quality PKAPB synthesis. Although a 45% DMAPA addition yields the highest quality product, it presents economic trade-offs due to increased raw material costs. These findings suggest that an optimal formulation should carefully balance product performance and economic feasibility. The data was generated through controlled lab-scale synthesis, with each experimental condition systematically varied and analyzed. It provides insights into the process-structure-property relationships in PKAPB production and is intended to support further research in surfactant synthesis and process optimization.
