Response surface optimization of ionic liquid pretreatments for maximizing cellulose nanofibril production.

ABSTRACT: Pretreatments with aqueous protic ionic liquid (PIL)-ethanolamine bis(oxalate) ([MEA][(HOA)(H₂OA)]), combined with ultrasonic disintegration, were employed in cellulose nanofibril (CNF) production from pulp fibers. The optimization of pretreatment parameters is crucial for obtaining the maximum CNF yield. The response surface methodology was used to design the pretreatment conditions for preparing CNFs. This method consists of four factors: pretreatment time (A, 2-4 h), pretreatment temperature (B, 100-120 °C), liquid-to-solid ratio (C, 60-80 g g^-1), and PIL content (D, 20-40%). The predicted CNF yield (Y) followed a quadratic multinomial regression equation represented by Y = 84.43 + 3.59A + 8.22B + 2.22C
