  • Methods for lowering pH in leather processing solutions
    Publication number: 20030038085
    Abstract: The present invention relates to methods for lowering the pH of leather processing solutions by adding a pH reduction agent that is urea sulfate, urea hydrochloride, triethanolamine hydrochloride, or triethanolamine sulfate as a replacement for conventional pH lowering acids, such as sulfuric acid, formic acid, acetic acid, etc. The invention may be used with respect to any leather processing step that requires pH adjustment, including deliming, pickling, tanning, dyeing, finishing, and retanning. The pH lowering method of the invention results in safer handling, more environmentally acceptable effluents, and decreased corrosion of process equipment.
