Scheme 5.36
Synthesis of rosin amine gluconolactone (N12)
The hydrophilicity of glycerol is weak but it can be improved by polymerisation
reactions. Rosin-based polyglycerol (N13) nonionic surfactants with different degrees
of polymerisation of polyglycerol were obtained (
Scheme 5.37
) by an esterification
reaction [57]. Wang and co-workers reported that the nonionic surfactant polyglycerol
maleated rosin ester (N14) was synthesised by the reaction of maleated rosin and
polyglycerol (
Scheme 5.38
). The relationships between the surface physicochemical
properties of the product and the degree of polymerisation of polyglycerol were
studied systematically [58].
