Precipitation is a widely used approach to separate and purify chemical substances. Because of its ease and reliability, precipitation is employed in mineralogy, materials engineering, and chemical preparation procedures. The CD BioSciences-GreenChemistry specialists apply their extensive experience in solving chemistry problems through precipitation, turning it into a tool for a wide variety of chemical separations and purifications.
The method of precipitation relies on precipitation reactions. In this case, the method of precipitation involves adding a chemical reagent to a separated solution to cause some of its substances to precipitate. Specifically, this method consists of combining a chemical reagent to achieve a chemical reaction that yields an insoluble compound, wherein both a precipitate and an insoluble compound are produced from the solution. Filtration or centrifugation may be used to remove this precipitate, and further purification may involve washing and drying.
CD BioSciences-GreenChemistry offers environmentally friendly separation and purification services based on precipitation methods with a dedicated team of professionals committed to green chemistry services. We offer precipitation methods that efficiently separate target compounds while minimizing chemical reagent use and waste generation.
We purify inorganic compounds by dissolving them in an appropriate amount of solvent and adding a suitable precipitant to them to cause them to form a precipitate. We select a suitable precipitant according to the chemical properties of the inorganic compound and accelerate the precipitation process by heating or adjusting the pH. For example, in a solution containing Fe3+, NaOH is added to produce Fe(OH)3 precipitate, which in turn purifies iron from the aqueous solution.
We separate and purify organic molecules by changing the solvent conditions, and temperature or adding precipitants to produce precipitation. For example, the crude raw material of pharmaceutical small molecule aspirin can be dissolved in green solvents such as alcohols, and changing its temperature and adding water to cool it can cause the target compound to undergo precipitation. After filtration and drying, high-purity aspirin can be obtained.
Depending on the nature of the macromolecular compounds, we use suitable precipitants such as ethanol, acetone, or polyethylene glycol. Under constant stirring, we slowly add the precipitating agent to the compound solution and make it fully form a precipitate by adjusting the temperature and pH. The precipitation method we offer can be used to isolate and purify macromolecular compounds such as proteins, nucleic acids, and polysaccharides.
CD BioSciences-GreenChemistry works tirelessly to meet the ever-increasing demand for chemical purification technologies while remaining economically viable and environmentally friendly.
