The optimum condition of methyl cellulose were 0.91% NaOH 3.52 ml of dimethyl sulfate, at 46.51Â☌ temperature. The addition of NaOH and dimethyl sulfate in producing methyl cellulose had more effect on the increasing of degree of substitution than temperature treatment. The results showed that the use of NaOH concentration, dimethyl sulfate and temperature affected the degree of substitution, OHC and lightness. ![]() Dimethyl sulfate can be acted as substitution agent, while temperature controlling plays role to obtain appropriate conditions for reaction. NaOH could change cellulose crystalline region and formed Na-cellulose. The optimization of methyl cellulose was done using Response Surface Methodology with various concentrations of NaOH (10, 15, 20, 25, 30%), dimethyl sulfate (2, 3, 4, 5, 6 ml), and temperature (45, 50, 55, 60, 65Â☌). Dehemicellulose and bleaching were done to dilute hemicellulose and lignin. The study was conducted by extracting cellulose using 4 % NaOH concentrations. This study aimed to understand the optimized the optimizing synthesis of methyl cellulose through the concentration of NaOH, dimethyl sulfate and reaction temperature. ![]() Cellulose can be processed into methyl cellulose And be used as food additive. The kernels of snake fruit are wastes, but contains a lot of cellulose. ![]() Pondoh is one of the snake fruit species largely found in Yogyakarta. Snake fruit ( Salacca zalacca) is one of the typical fruits from Indonesia. ![]()
