Effect of Temperature and Catalyst Concentration on Polyglycerol during Synthesis

Table 1

Summary table of polyglycerol hydroxyl numbers obtained under different synthesis conditions at three temperatures and catalyst concentrations. Standard deviations were calculated based on triplicates. Three replicates per assay were taken.

130	3.35	441.2 ± 4.2
130	5.2	566.1 ± 12.4
150	1.5	525.8 ± 28.4
150	3.35	506 ± 23
150	5.2	390.1 ± 13.3
170	1.5	413.1 ± 23.8
