Abstract

Beschrieben wird ein Verfahren zur Herstellung eines unsymmetrischen Kohlensäureesters der Formel (I) DOLLAR F1 mit folgenden Schritten: DOLLAR A Umsetzen eines Glykols der Formel (II) DOLLAR F2 mit einem Chlorameisensäureester der Formel (III) DOLLAR F3 zu dem Kohlensäureester (I), DOLLAR A wobei vor oder während der Umsetzung eine Base zugegeben wird, so dass entstehendes HCI teilweise oder vollständig neutralisiert wird, DOLLAR A wobei das Glykol der Formel (II) und der Chlorameisensäureester der Formel (III) während der Umsetzung in einer homogenen flüssigen Phase vorliegen.A process for the preparation of an unsymmetrical carbonic acid ester of the formula (I) DOLLAR F1 comprising the following steps: DOLLAR A reaction of a glycol of the formula (II) DOLLAR F2 with a chloroformate of the formula (III) DOLLAR F3 to the carbonic acid ester (I), DOLLAR A wherein before or during the reaction, a base is added so that the resulting HCl is partially or completely neutralized DOLLAR A wherein the glycol of formula (II) and the chloroformate of the formula (III) during the reaction in a homogeneous liquid phase.
