Title: Innovator Pramod Shankar Kumbhar: Pioneering Processes in Chemical Production

Introduction

Pramod Shankar Kumbhar, based in Bengaluru, India, is a distinguished inventor with a notable portfolio of 12 patents. His innovative contributions to the chemical industry have focused significantly on processes that enhance productivity while minimizing impurities. Kumbhar's work is a testament to the intersection of creativity and practicality in modern science.

Latest Patents

Among his most significant achievements is the invention of an integrated process for the production of bisphenol A (BPA) from cumene hydroperoxide (CHP). This innovative method utilizes a specific combination of catalysts in both the first and second steps of the conversion of CHP to BPA, achieving high yields of BPA while reducing impurity levels. Remarkably, this process eliminates the need for intermediate purification steps. In the initial step, CHP is cleaved in the presence of acid-treated Montmorillonite clay, yielding phenol and acetone. Subsequently, in the second step, this phenol and acetone can be reacted without intermediate purification, using a cation exchange resin catalyst along with either a mercaptan or mercaptoalkanoic acid promoter to produce BPA.

In addition, Kumbhar has developed another integrated process for the production of BPA from CHP, employing a sulfated metal oxide catalyst such as sulfated Zirconia in the first step. This approach similarly aims for high yields of BPA while retaining efficiency in production.
