antozone1858
1858 C. F. Schönbein Let. 25 June in M. Faraday Corr. (2008) V. 394 I think I can now prove the correctness of that old idea of mine, according to which there are two kinds or allotropic modifications of active oxygen, standing to each other in the relation of + to −, i.e. that there is a positively-active and a negatively-active oxygen,—an ozone and an antozone, which on being brought together neutralize each other into common or inactive oxygen.
1868 J. D. Dana Syst. Mineral. (ed. 5) 124 Its [sc. Antozonite's] strong antozone odour is said often to produce headache and vomiting in the miners.
1924 Proc. Royal Soc. A. 105 135 Accumulation of ozonic oxygen (removed by excess of indigo) would diminish the active mass of the antozone oxidising the phosphorus.
1965 Chymia 10 133 In the meantime, Schönbein had discovered the difference between ozone and antozone.
