Title: The Innovative Contributions of Stefano Bigini
Introduction
Stefano Bigini is a notable inventor based in I-Terni, Italy. He has made significant contributions to the field of chemistry, particularly in the production of sodium percarbonate. With a total of 3 patents to his name, his work has advanced the methods of producing this important compound.
Latest Patents
One of Bigini's latest patents focuses on a novel process for producing sodium percarbonate. Traditionally, sodium percarbonate is made through a crystallization process involving aqueous hydrogen peroxide and sodium carbonate, utilizing a salting-out agent, typically sodium chloride. Bigini's invention eliminates the need for chloride salting-out agents, controlling the dissolution step to maintain sodium carbonate concentration below 95%, ideally between 60 to 90% of its saturated concentration at a maximum temperature of 35°C. The mole ratio of hydrogen peroxide to sodium carbonate in the reaction vessel is carefully regulated between 0.7 to 1.2:1, with a preferred ratio of about 1:1. His process also introduces large particle sodium percarbonate, which exhibits a lower heat emission compared to conventionally produced sodium percarbonate.
Career Highlights
Throughout his career, Stefano Bigini has worked with prominent companies such as Solvay Interox and Solvay Interox SA. His experience in these organizations has contributed to his expertise in chemical processes and innovations.
Collaborations
Bigini has collaborated with notable colleagues, including Soraya Parvaneh and Romano Pardini. These partnerships have likely enriched his research and development efforts.
Conclusion
Stefano Bigini's innovative work in the production of sodium percarbonate showcases his commitment to advancing chemical processes. His patents reflect a significant step forward in the industry, emphasizing efficiency and sustainability.
