Synthesis of lead-copper cpd. of 2,4-di:hydroxy-benzoic acid for ballistic modifier in double base propergol solids

摘要

The synthesis of a Pb-Cu cpd. of 2,4-dihydroxy-benzoic acid comprises mixing in aq. soln., a Pb2+ cpd. Cu2+ cpd. and 2,4-dihydroxy-benzoic acid to attain a constant pH, followed by filtration of the reaction mixt. The acid is first mixed with the mineral Cu cpd. (with stirring) to attain a constant pH; the mixt. is then de-gassed and the Pb cpd. is added with stirring to a constant pH. Also claimed is a new double base solid propergol compsn. which contains the Pb/Cu cpd. described above as the ballistic modifier additive.
