Sintesis silika tersulfonasi dari waterglass dengan templat PEG sebagai katalis asam padat dalam pembuatan pelumas dari minyak nabati Synthesis of sulfonated silica from waterglass with PEG template as solid acid catalyst in the production of lubricant from vegetable oil
Abstract:The use of a catalyst in the manufacture of lubricantscome through many developments, from a homogeneousbase catalysts, homogeneous acid catalyst to hetero-geneous solid catalyst system (heterogenous catalyst). Oneexample of heterogeneous catalyst base material is silica.The purpose of this research was to study the graftingmethod of sulfonic group on silica from waterglass withPEG (polyethylene glycol) template as solid acid catalystand to analyze the effect of PEG concentration on ioniccapacity. Silica sol w… Show more
