Optimization for Production Tert-Butyl Glycoside Nonionic Surfactant Using Response Surface Methodology

Abstract

Abstract It is necessary to develop a surfactant production process using environmentally friendly raw materials and products. For raw materials such as surfactants are carbohydrate-based material utilization example, glucose, which is reacted with tert-butanol, to form tert-butyl glycoside (TBG). This study aims to obtain the optimum conditions TBG production process of acetalization reactions, glucose and tert-butanol, catalyst the para toluene sulfonic acid using response surface method to reach optimum yield TBG. The independent variable used is the mole ratio of glucose with tert-butanol, percent of the catalyst and a temperature. Optimization results obtained optimum conditions of mole ratios of 1: 5.06; 2.87 percent of the catalyst and the temperature of 71.21 °C with a TBG yield of 99.13%, with a TBG content of 61.2 %. The optimum process conditions are verified to strengthen the model equations obtained by the response surface method. Based on the Hydrophilic-Lipophilic Balance value of the surfactant TBG is 4.60, then these surfactants can be used as an emulsifier of water-in-oil.
