EXPLORATION OF CATALYSTS FOR POLYGLYCEROL SYNTHESIS
Biodiesel is a renewable energy source that has lately seen a rise in output. By acquiring 10-20% of the entire output volume, high biodiesel production increases the amount of glycerol produced as a by-product (Fahrizal, 2014). The price of glycerol can be reduced if more glycerol is produced. T...

| Summary: | Biodiesel is a renewable energy source that has lately seen a rise in output. By
acquiring 10-20% of the entire output volume, high biodiesel production increases
the amount of glycerol produced as a by-product (Fahrizal, 2014). The price of
glycerol can be reduced if more glycerol is produced. To keep glycerol's price
stable, it must be converted into high-value derivative products. As a result,
research into the synthesis of glycerol derivative chemicals such polyglycerol is
required. Polyglycerol is a molecule made up of one or more glycerols that has
gone through an oligomerization stage. Polyglycerol can be utilized as is or
processed into additional derivative molecules that can be used to replace fossil
fuel derivatives.
In this work, catalysts were investigated in order to create polyglycerol from
glycerol at lower temperatures than previously used, as well as polyglycerol with
low glycerol monomers such as diglycerol, triglycerol, and tetraglycerol. KOH,
K2CO3+ZnO, and CaO+ZnO are the catalysts that will be evaluated. High-
Performance Liquid Chromatography (HPLC) with a Shodex SH1011 column at a
column temperature of 50oC will be used to evaluate reaction samples.
