Electrical Firing Properties of Some Lead Compounds of Nitrated Resorcinol. Lead Mononitroresorcinol (LMNR), PbC CgH NO ) (See p D1271-L in this Vol), used in electric squibs has a lead content betw 68 77%.

The lead salt of mononitroresorcinol was in use in electric detonators for making fuschcads. Some of them may be composed of this salt and dextrinated lead azide (159,160). 

An alternative preparation method involves the ammonia salt of 2,4,6-trinitroresorcine [24, 64, 66]. The formation of the desired form and crystal shape depends on reaction conditions. The addition of 2-mononitroresorcinol in an amount between 0.1 and 5 % is sometimes employed in the preparation of the red form to improve its bulk density and flowability [24, 64]. The presence of foreign substances in the starting 2,4,6-trinitroresorcine (added in the suUbnation operation in the preparation of styphnic acid) has also a significant influence on the shape of basic LS crystals [70]. Various procedures are patented for preparation of red [24, 64,65, 71] and yeUow [39, 64—67] basic lead styphnate. Just like LS, the basic LS can also be prepared as a jelly (see lead styphnate).
