Separation of levulinic acid from the rejected stream and fermentation broth has become topic scientific interest or importance due to its variety applications. In present paper, optimization study is carried out find maximum separation efficiency using various independent variables like initial concentration acid, trioctylamine extractant, temperature, time. The response surface methodology in combination with central composite design (face-centered) was employed involving 30 experimental...

Separation of levulinic acid (LA) from the aqueous phase with use tri-n-butyl phosphate (TBP) as an extractant in nontoxic solvents such rice bran and mustard oils was performed. The are low cost compared to other solvents. obtained maximum extraction efficiencies (%E) 11.75%, 8%, 70% pure oil, TBP, respectively. distribution coefficient (KD) %E were found be lower vegetable oils. To improve separation, TBP used various concentrations In present study, higher KD 1.42 58.73% oil 1.61 61.75% oil.

The separation of levulinic acid from aqueous solutions is costly and non-ecofriendly in many cases.The major concerns are the low concentration fermentation broths industrial downstreams.In this study, reactive extraction phase proposed its efficacy was investigated.Various extractants viz.tri-n-butyl phosphate, trioctylamine, trioctylmethylammonium chloride along with i-octanol as a diluent were used.The extent investigated various performance parameters like efficiency, distribution...

Succinic acid (SA) is a platform chemical for producing biofuel and other green chemicals. Fermentative SA production cost – effective eco friendly method, with quite few downstream challenges. The recovery method of reactive extraction shows promise but faces toxicity issues the diluent extractant, especially concerning microorganisms in fermentation broth. Hence, non toxic or less combinations, are needed efficient recovery. diluents, groundnut oil sesame oil, were evaluated. Based on...

Abstract BACKGROUND Levulinic acid is one of the top ten bio‐derived platform chemicals essential for producing many products that are used daily. The recovery biobased from industrial streams and fermentation broths critical due to environmental issues. A few studies have chemical solvents levulinic acid, but these toxic microorganisms. Therefore, green cheap separation needed. This study sunflower oil as a solvent with trioctylamine tri‐n‐butyl phosphate acid. experimental was presented in...

Abstract Glutaric acid is an attractive chemical compound which can be used for the manufacturing of polyesters, polyamides, and polyols. It produced by synthesis (chemical method) fermentation (biological process. presented with lowest quantity in broth industrial waste streams. The separation methods glutaric are difficult, costly, non-environment friendly from broth. Reactive a simple, cheapest, environment-friendly process recovery carboxylic acid. Which employed lower cost In this...

Abstract BACKGROUND Vanillic acid, an aromatic carboxylic acid and a derivative of vanillin, is used as additive in consumer goods for its aroma. Previously, most vanillic was produced through petrochemical route, but consequence stringent environmental policies, it now by the biotransformation ferulic acid. also found wastewater streams paper‐pulp industries olive‐oil mills. So, recovering from fermentation broth, either during bioproduction or stream, while minimizing toxicity, difficult...

The extraction behaviour of Mo(VI) from nitric acid medium was investigated employing di(octyl-phenyl) phosphoric (DOPPA) in different diluents. Dodecane found to give higher DMo value as compared other diluents (under similar conditions). decreases with HNO3 concentration up 3 M and increases thereafter 10 M, suggesting that two mechanisms are involved this system. Speciation studies show HMoO3.(HA2) MoO2.2(HA2) the predominant species at 0.1 HNO3, whereas 6 is MoO2(NO3)2.2(HA). Selectivity...

Abstract Many industries are using directly biomass as a raw material for the production of valuable biochemicals. These used different toxic chemicals such sulphuric acid, hydrochloric nitric etc. catalyst during biochemicals and exit downstream waste create environmental pollution. Therefore, separation is important decrease Levulinic acid carboxylic which can be present industrial waste. It very chemical transformed into 1–4 pentanediol, aminolevulinic succinic gamma valarolactone,...

Agriculture waste residue can be termed as low-cost renewable sources capable of sufficient energy and chemical supply in the future. Levulinic acid or 4-oxopentanoic (C5H8O3) is a carboxylic with ketonic group. It used nylon, fuel, pharmaceutical, food, tobacco, cosmetics, solvent, etc. The demand for levulinic continuously increasing various sectors such biofuel industry.
