2.4.6- Trinitrobenzene-1,3-diol

Lead styphnate (lead salt of 2,4,6-trinitrobenzene-1,3-diol, LS, LTNR, tricinate) was, according to the well-established reference [8], first prepared by Edmund von Herz in 1914 by reaction of magnesium styphnate with lead acetate in presence of nitric acid. However, in reality, preparation of LS was published more than 40 years earlier by Stenhouse [28]. This discrepancy in historical data is probably caused by the fact that Herz patented the substance as a component of a detonator primary charge and was therefore the first one who found some real application [29,30]. The preparation route used by Stenhouse is based on the reaction of lead acetate with an aqueous solution of styphnic acid [28].

Barium styphnate (barium salt of 2,4,6-trinitrobenzene-l,3-diol BaS) forms an anhydride and two hydrates, monohydrate and trihydrate only the anhydride and the monohydrate are used in practical applications [20,75,76]. According to Bagal the monohydrate of barium styphnate exists in three polymorphic forms listed in Table 5.9 [33].
