In 2022,Santra, Somtirtha; Maharana, Debasis; Kotecha, Prakash; Banerjee, Tamal published an article in Industrial & Engineering Chemistry Research. The title of the article was 《Process Simulation and Multiobjective Optimization for High-Purity Hexane Recovery Using Deep Eutectic Solvent》.Name: Methyltriphenylphosphonium bromide The author mentioned the following in the article:
Deep eutectic solvents (DESs) are an exptl. proven and attractive solvent in the field of green chem. for aromatic extraction from a mixture of aliphatic-aromatic mixtures The current work reports a multiscale strategy using quantum chem. calculations, thermodn. models, process simulation, and multiobjective optimization for the simultaneous production of high-purity hexane and aromatic removal using the DES Me tri-Ph phosphonium bromide/ethylene glycol (1:4). Initially the phase equilibrium data have been benchmarked through the continuum solvation-based COSMO-SAC model, which has a root-mean-square deviation of 5.81%. Thereafter, a conceptual multiloop extraction and solvent recovery process has been developed and simulated that incorporates sensitivity anal. to analyze the impact of different process parameters on the system. These parameters, namely, annualized capital cost, benzene content in the hexane product stream, and hexane recovery, have been further formulated as three sep. objective functions to be optimized using a nondominated sorting genetic algorithm. After optimization, a series of solutions have been obtained from the Pareto front. The results provide 92% hexane recovery with a benzene concentration of less than 50 ppm. This shall enable the industrial production of high-purity hexane using efficient and sustainable green solvents. The experimental process involved the reaction of Methyltriphenylphosphonium bromide(cas: 1779-49-3Name: Methyltriphenylphosphonium bromide)
Methyltriphenylphosphonium bromide(cas: 1779-49-3) is an organophosphorus compound, with potential use as a precursor and a solvent in organic synthesis. And it is used widely for methylenation via the Wittig reaction.Name: Methyltriphenylphosphonium bromide
