Title: Vyacheslav K. Rykov and His Acrolein Production Patent.
Introduction
Vyacheslav K. Rykov is an inventor associated with Volzhsky, Russia. His recorded patent concerns a method for producing acrolein through the gas-phase aldol condensation of acetaldehyde and formaldehyde. The available information lists 1 patent for Rykov.
Latest Patents
Rykov’s listed patent, “Method of Producing Acrolein,” describes evaporating acetaldehyde and formaldehyde in the presence of diphenyl-N-nitrosamine, then feeding their vapors into a gas-phase aldol condensation process. The reaction takes place over coarsely porous silica gel promoted with 10 to 12 weight percent sodium silicate at 270 to 300 degrees Celsius, with diphenyl-N-nitrosamine also present during condensation.
The resulting gas mixture is cooled to form a condensate, which is separated by rectification. An aqueous formaldehyde solution is concentrated and returned to the evaporation stage, while a mixture containing acrolein, acetaldehyde, and water undergoes further rectification. The process recycles acetaldehyde containing a small amount of acrolein and isolates the acrolein product.
According to the patent description, the method is designed to prevent resin formation during aldehyde evaporation, continuously remove resins formed during condensation, and support continuous rectification. It also reports an acrolein content of 91 to 93 percent in the distillate.
Career Highlights
The available record highlights Rykov’s work on chemical-process engineering, particularly the production and purification of acrolein. The supplied information does not identify a specific company or provide further details about his career.
Collaborations
Rykov’s listed coworkers include Alexandr I. Valdman and Boris Nikolaevich Gorbunov. The available information does not specify their individual roles in the patent.
Conclusion
Vyacheslav K. Rykov’s recorded patent presents an integrated approach to acrolein production, combining gas-phase condensation, continuous separation, and process-stream recycling to improve product purity and manage resin formation.
