This to prepare consists of a lead on the basis of a new lead monoxide

摘要

P the present invention relates to a process for the to prepare of the compounds of lead, whose composition is represented by the following general formula: pbxou x represents a residue of a mineral or organic acid, x is the valency of the remainder of the x and n is a number from 0 to 5. / p & & p & the process according to the invention is to make a lead monoxide react having a density of a true 8,3 9,2gcm, a mean size of the particles do not determined 0,2mm, an absorption peak has an infrared wave number of 1400 a 1410cm and a reactivity of chromic anhydride of at least 94, with a mineral acid, an oxide acid, an organic acid or a functional derivative corresponding. / p
