Title: Vladimir Avgustovich Yanshevsky: Innovator in Chemical Processes
Introduction
Vladimir Avgustovich Yanshevsky is a notable inventor based in Novokuibyshevsk, SU. He has made significant contributions to the field of chemical processes, particularly in the area of phenol alkylation. With a total of 4 patents to his name, Yanshevsky has developed innovative methods that enhance the efficiency and effectiveness of chemical reactions.
Latest Patents
Yanshevsky's latest patents include a method for removing aluminum-containing catalysts from phenol alkylation products. This method involves treating the products with water at temperatures ranging from 165°C to 250°C, with water in molar excess to aluminum. The resulting residue of meta-aluminate can be easily separated by filtration. This invention allows for the elimination of constant control of aluminum content in alkylation products, facilitating the easy removal of the catalyst and preventing the loss of valuable phenol alkylation products.
Another significant patent is a method for preparing 2,6-ditert.butylphenol. This method comprises the alkylation of phenol in the presence of monotert.-butylphenol and a catalyst, specifically aluminum dissolved in phenol. The process involves gradually lowering the temperature from 120°C to 50°C and reducing the concentration of isobutylene in the mixture of isomeric butenes. This innovative approach achieves a high degree of conversion of isobutylene while maintaining the quality of the desired product, resulting in a significantly lower amount of by-products compared to prior art methods.
