Title: Innovations in Tanning Agents by Palanisamy Thanikaivelan
Introduction
Palanisamy Thanikaivelan is a notable inventor based in Chennai, India. He has made significant contributions to the field of synthetic tanning agents, focusing on eco-friendly alternatives to traditional methods. With a total of 5 patents, his work is paving the way for sustainable practices in the leather industry.
Latest Patents
Thanikaivelan's latest patents include a process for preparing a synthetic aluminium tanning agent. This innovative agent serves as an alternative to chromium-based tanning salts without the use of formaldehyde. The synthetic aluminium tanning agent is created using an aromatic polymeric matrix and aluminium (III) salts, along with suitable masking agents. The preparation involves sulphonation of the aromatic molecule, which is integrated into a polymeric network with specially designed ligands for complexing aluminium (III) salts. This complex can be utilized as a self-tanning agent in the leather industry, demonstrating good filling behavior. The tanned leathers exhibit a shrinkage temperature of about 85°C. Due to the higher precipitation point of the product, it can be used for tanning directly after deliming, thus eliminating the pickling process. Unlike conventional phenol-based products, this innovation does not undergo photo-oxidation, preventing discoloration of the tanned leathers.
Another significant patent is the process for the preparation of a formaldehyde-free synthetic tanning agent. This process involves polymerizing a multifunctional polymer with a sulfonated aromatic compound, pretreated with an organic ligand to form an organo-polymeric matrix that is essentially formaldehyde-free. This product has potential applications in the leather industry as an eco-friendly approach to chrome tanning, eliminating the conventional pickling process and addressing the issues related to total dissolved solids (TDS) in effluent. The invention also provides an exhaust aid for chrome due to its multiple carboxyl groups.
