Latest Patents

One of her latest patents is titled "Continuous production of DMAEA quaternary salts." This invention provides a method for continuously producing high-quality quaternized N,N-dialkylaminoethyl (meth)acrylates (DMAEA.MCQ) that boasts a long shelf life and stability in water. The method involves placing starting materials into a continuously stirred tank reactor with less than 6% water, which prevents unwanted side reactions and allows for the formation of two liquid phases. The denser phase contains DMAEA.MCQ, while the lighter phase contains the starting materials. The liquid from the denser phase is removed carefully to ensure high purity DMAEA.MCQ is produced.

Another significant patent is for the "Production of N,N-dialklylaminoethyl (meth)acrylates." This invention describes a method and apparatus for preparing N,N-dialkylaminoalkyl acrylates through a continuous transesterification reaction. The process involves adding alkyl acrylates to a reboiler mechanism while efficiently removing alcohol co-products. The continuous nature of the reaction allows for adjustments in output and fine-tuning of the reaction dynamics, enhancing the overall efficiency of the production process.
