Patent ID: 8404850

Claim:
A bis-quaternary pyridinium-2-aldoxime salt of the formula: wherein R is a halogen and said salt indicates a plurality of distinguishing x-ray diffraction peaks at 2 Theta angles of 10-35 degrees as compared to non-distinguishing x-ray diffraction peaks at 2 Theta angles of greater than 35 degrees, wherein said distinguishing x-ray diffraction peaks have relative intensity counts between 500-1500 at 2 Theta angles of 10-35 degrees and non-distinguishing x-ray diffraction peaks have relative intensity counts of less than 500 at 2 Theta angles of greater than 35 degrees and no peaks are present with relative intensity accounts of more than 250 at 2 Theta angles between 35-60 degrees and wherein said salt has a particulate structure and an aspect ratio of 2:1 to 16:1.
