The invention relates to organic chemistry, in particular to compositions for obtaining light emission in the course of the chemiluminescent reaction.Chemiluminescent compositions (Khibiny-Lovozero alkaline complex), as a source of visible light, are well known and are produced in the global industry. Light sources based on the Khibiny-Lovozero alkaline complex are widely used mainly as a safe, nadejnogo lighting or signalling.The industry produces Khibiny-Lovozero alkaline complex on the basis of the most efficient currently on the light output peroxide-oxalate systems, in particular on the basis of the bis/2,4,5-trichloro-6-carbomethoxybiphenyl/oxalate or other similar chlorinated aromatic substances. Further the industrial production of such Khibiny-Lovozero alkaline complex insurmountable difficulties because of the increasing demands of environmentalists lead to the prohibition of the use of such chlorinated aromatic substances because of the danger of infection of nature powerful toxicants, such as 2,3,7,8-tetrachlorodibenzo-p-dioxin or its analogs.Increasing environmental and other complex requirements for the competitiveness of the Khibiny-Lovozero alkaline complex has forced researchers to refer to the Khibiny-Lovozero alkaline complex based on the derivatives of glyoxal, for example bis/1-(1H)-2-pyridinyl/glyoxal. This substance is capable under the influence of oxidizing agents to cause sensitization of the chemiluminescent reaction with a lower quantum yield than chlorinated derivatives of oxalic acid, but in contrast to the latter is not able to generate in the Khibiny-Lovozero alkaline complex ecotoxicants and can be used to create environmentally safe chemical sources of conformitiy for over twenty-five years [1 6] the professionals they are available mainly in laboratories and test samples, as suitable for mass-production technology, competitive Khibiny-Lovozero alkaline complex must meet the complex hard diversified requirements.Data on composition, light and energy characteristics known from literary sources chemiluminescent compositions based on bis/1-(1H)-2-pyridinyl/glyoxal are given in table. 1 with reference to the source.It should be noted that in table. 1 includes data from the most effective of the Khibiny-Lovozero alkaline complex described in the literature.
