Latest Patents

Anna holds a patent for a method of producing 2,4,6-tri(3,5-ditertiary butyl-4-hydroxybenzyl)mesitylene. This method involves treating a mesitylene solution in chloroalkane with sulfuric acid as a catalyst, along with a solution of 2,6-ditertiary butyl-4-methoxymethylphenol or bis-3,5-ditertiary butyl-4-hydroxybenzyl ether. The process occurs at temperatures ranging from -20°C to +20°C, resulting in a reaction mixture that separates into an acid phase and an organic phase containing the target product. The organic phase undergoes neutralization with gaseous ammonia, leading to a high yield of 88 to 90% and a melting temperature of 239°C to 239.5°C. This method is notable for preventing effluents and significantly reducing phenol waste.
