  In a chemiluminescent lighting system having separated components in storage before use, at least one of the separate components is stored in a container made from a laminate of polypropylene film and aluminium foil. Good stability of both oxalate ester components and hydroperoxide components when stored in such containers is demonstrated.

  The present invention relates to a process for producing a diaryl oxalate, characterized in that an alkylaryl oxalate is subjected to a disproportionation reaction in the presence of a disproportionation catalyst, thereby to produce a diaryl oxalate while removing a by-product comprising a dialkyl oxalate. The production process of the present invention is advantageous in that the kinds of the by-products are fewer than that in conventional production process for diaryl oxalate, and thus can be practically utilized in industry, and the diaryl oxalates such as diphenyl oxalate, produced by the production process of the present invention are very important industrial materials for producing chemical products such as carbamates.

  本发明涉及一种草酸二芳基酯的生产工艺，其特征在于在歧化催化剂存在下，对草酸烷基芳基酯进行歧化反应，从而生产草酸二芳基酯，同时除去由草酸二烷基酯组成的副产品。 本发明生产工艺的优点在于副产品的种类比传统草酸二芳基酯生产工艺少，因此可在工业中实际利用，而且本发明生产工艺生产的草酸二芳基酯，如草酸二苯酯，是生产氨基甲酸酯等化工产品的非常重要的工业原料。

  An improved process for preparing a diaryl carbonate from a diaryl oxalate in a liquid phase by decarbonylation utilizes a reaction vessel composed of two or more reaction chambers which are connected in series. The process is composed of the steps of continuously introducing the diaryl oxalate and an organic phosphorus compound having a trivalent or pentavalent phosphorus atom and at least one carbon-phosphorus bonding into the first chamber and continuously recovering a reaction mixture mainly containing the diaryl carbonate from the last chamber under the condition that a mixture of the diaryl oxalate and the organic phosphorus compound is heated in the reaction chambers, while discharging carbon monoxide released from the mixture.
