  Chemical light producing systems and the chemiluminescent formulations contained therein are taught which exhibit reduced hydrolysis and thereby are characterized by an inherently long shelf-life and commercial viability. By replacing the typical oxalate ester, e.g. (bis3,4,6-trichloro-2-[(pentoxy)carbonyl] phenyl} oxalate) with a branched chain oxalic acid ester represented by the general formula: wherein the group designated as R contains from 4-15 carbons, wherein the carbon of attachment of R to the oxygen is via a primary carbon, and wherein substructure A is composed of substituents selected from the group including alkyl chains, alkyl rings, aromatic rings and combinations thereof such that R is nonlinear, water hydrolysis of the oxalate ester is retarded. This retardation of the hydrolysis changes the storage constraints of the oxalate ester.

  本文介绍了化学发光系统和其中所含的化学发光配方，其表现出降低的水解反应，因此具有固有的长期保存和商业可行性。通过用一种分支链草酸酯代替典型的草酸酯，例如（双3,4,6-三氯-2-[(戊氧)羰基]苯基}草酸酯），其表示为通式：其中R标示的基团含有4-15个碳，R与氧原子的连接碳原子为一级碳，且亚结构A由选自烷基链，烷基环，芳香环和它们的组合的取代基组成，使得R为非线性结构，草酸酯的水解反应被延缓。这种延缓水解反应改变了草酸酯的储存限制。
