Levulinic acid Usage And Synthesis
Content analysisAccurately weigh about 1.0 g of the sample, and put it into a 250ml Erlenmeyer flask containing 75~100ml water, add phenolphthalein test solution; apply 0.5 mol/L sodium hydroxide for titration to until it began to appear pink and maintain 15 s. Each mL of 0.5mol/L sodium hydroxide solution is equivalent to 58.08mg of the goods.
Physicochemical PropertiesWhite flake crystals, hygroscopic. It is easily soluble in water and alcohol, ether organic solvents.
ApplicationIt can be used as the raw materials of medicine, spices and paint, and used as solvent.
This product has wide applications. Levulinic acid can be used as both a carboxylic acid and can also be used as a ketone for reaction for making various kinds of products through esterification, halogenation, hydrogenation, oxidation dehydrogenation, condensation, etc., including resins, pharmaceuticals, spices, solvents, rubber and plastic additives, lubricants additives, surfactants and so on. In the pharmaceutical industry, its calcium salt (calcium fructose) can be used for intravenous injection. As a nutritional medicine, it helps to boost the formation of bone and maintain the normal excitability of nerves and muscles. It can also used for the production of indomethacin and plant hormones. Levulinic acid manufactured bisphenol acid can be made of water-soluble resin, used in the paper industry to produce filter paper. Levulinic acid is also an intermediate of pesticides and dyes.
Used for biochemical reagents, but also for organic synthesis
It can be used as an important chemical raw material or solvents. It can be used for the manufacturing of medicine (intravenous injection, indomethacin, etc.), resin (bisphenol acid water-soluble resin), spices (spices or tobacco spices), paint, paint, pesticides, and surfactants.
It can be used for biochemical research; manufacturing of esters and drugs. It is also the inhibitor of chlorophyll synthesis.
PreparationThe residue during the manufacturing of furfural with cotton seed shell or corncob sugar (furfural residue) or waste taro residue, through pressured hydrolysis with dilute acid, can be used to produce levulinic acid. The furfural residue was added to 10% dilute hydrochloric acid, the solidified solution was 1: 1.75, mixed and put into the hydrolysis pot, steamed at a pressure of 0.2MPa for 8-10 h. The diluted solution is then filtered and concentrated to a concentration of about 50%. It is further subject to vacuum distillation for collecting the fraction above 130 ℃ (2.67kPa) to obtain the finished product. Raw material consumption quota: potato tacar 7,000 kg/t, hydrochloric acid (fold 100%) 1800kg/t. Another method is manufacturing through the rearrangement and hydrolysis of sugar alcohol.
4% hydrochloric acid solution was added to the reaction pot, stir and heat to 97-100 ℃, slowly add the mixture of furfuryl alcohol, ethanol and water. After addition, stir 30 min. The filtrate was concentrated at 80 ° C (21.3 kPa) under reduced pressure to give crude levulinic acid. Then apply vacuum distillation, collect the fraction of 160-170 ° C (2.67kPa), and then re-distill once, to obtain the refined levulinic acid with the yield of about 75%.
