Latest Patents

Among his latest patents, one notable invention is the "Processes for crystallizing 4, 4'-dimethyl bibenzoate (DMBB) recovered." This patent discloses methods for recovering DMBB from byproduct streams of dimethyl terephthalate (DMT) production. The process involves treating byproduct streams to produce an overhead stream that includes DMBB. In one aspect, the overhead product stream is added to an organic solvent to rapidly form a suspension of crystallized DMBB. Another aspect involves dissolving the overhead in an organic solvent and cooling it to form a suspension of DMBB crystals. Additionally, the overhead stream can be treated with an organic solvent to create a slurry of DMBB crystals, which is then thermally treated to enhance the concentration of DMBB while solubilizing organic contaminants.

Another significant patent is the "Process for acylation or alkylation of aromatic compounds in hydrogen." This continuous process involves the acylation or alkylation of aromatic compounds in hydrogen fluoride, where the aromatic compound is sufficiently insoluble in hydrogen fluoride to form a two-phase reaction medium. Surprisingly, the product acylated or alkylated aromatic compound is soluble in hydrogen fluoride. This invention particularly relates to a continuous, multi-stage process for carrying out the reaction, which can be operated to ensure complete consumption of the aromatic compound feed or allow for recycling of unreacted material.
