Procedure
84.5 mmoles of trimethylolhexane and 70.9 mmoles of carbamide were together with 1.2 mole % of potassium hydroxide (based on total amount of reactants and catalysts) charged in a reaction vessel. The synthesis was performed in accordance with Example 1. The temperature uring the pyrolysis gradually raised to 215° C. 20.6 mmoles of 3-hydroxymethyl-3-pentyloxetane (trimethylolhexane oxetane) was yielded from the distillate and characterised by NMR. The remainder contained the spiro-orthocarbonate (3% on the carbamide) yielded as by-product.
