Reaktionsschritte

In a stirred 1 liter apparatus under a stream of nitrogen, 219.0 g (1.5 mol) of isosorbide and 461.4 g (3.2 mol) of caprylic acid are heated with stirring and under a stream of nitrogen to 180° C. The reaction mixture was heated at 180° C. until no more water of reaction distilled off (about 28 h). The temperature was then gradually increased to 210° C. (altogether over about 30 h). The reaction has ended when a residual acid value of <2 mg KOH/g is reached. This gives a clear red-brown solution.
