Turmeric is looking to become natural alternative materials in the production of plastic BPA
In our daily life, filled with all kinds of plastic products.Around half the world's resources are used in the production of plastic packaging materials2.Health about the inherent nature of plastic materials for consumer packaged goods (CPG) provides a huge market advantage.In this field, however, it is necessary for us to identify some of the potential risk to the consumer or the environment exist compounds, to study, and its elimination from the global supply chain.Therefore, we need to plastic synthetic as well as the use of toxic materials in the process of study.Bisphenol A (BPA), for example, is one such example, it is A kind of main polycarbonate plastic, many researchers are studying it and the correlation of unhealthy symptom such as obesity and diabetes.In addition, some researchers are studying bisphenol A, as A kind of endocrine disruptors and the relationship between infertility and cancer and other diseases.Plastic is usually exist in the form of micro plastic, in addition to the harm to human health, also will pollute the natural environment, and harm of ecological system and its creatures.
For some of the efforts to develop a more sustainable and renewable solutions of chemists and biologists, human complications and environmental damage caused by plastic and its production is an important breakthrough.These solutions include, cleaner and more sustainable alternative materials to replace bisphenol A, polycarbonate are toxic to replace it.Therefore, for the global researchers, using the effective analysis technology, the new plastic material characteristics of intermolecular and intramolecular real-time research is crucial.According to the design, the new material will be suitable for recycling, and impact on the environment to reduce to a minimum.
Curcumin is what?Why curcumin is the appropriate choice of alternative BPA?
Chemical biology from the university of bari in Italy A group of scientists has broken the BPA as precursor dominance of plastic products - they are using curcumin instead of bisphenol A, synthesized by A new type of bio-based renewable polycarbonate.Curcumin (CM) is a kind of natural antioxidants, and have anti-inflammatory, antibacterial and anticancer properties.Curcumin is the result of turmeric plant, its chemical structure similar to bisphenol A.On the stability and solubility in water and the structure of the curcumin adaptability to improve after the research team at the university of bari choice as it leads to the preparation of bisphenol A polycarbonate suitable alternative products.
Use of curcumin and THCM synthetic biology bisphenol A substitute products
The team participated in the biological synthesis process of bisphenol A substitute products, the synthesis process can be decomposed to trans polymerization process, mainly divided into two steps.The first step is bisphenol A polycarbonate (BPA - PC) and phenol depolymerization, generate A called "diphenyl carbonate (DPC) of the product.Then, the researchers used curcumin or four hydrogen curcumin (THCM), to melt the ester exchange reaction, DPC preparation as A substitute for bisphenol A polycarbonate products to final product.These products are still has the same function with bisphenol A polycarbonate, but do not have negative properties of bisphenol A (bpa).
In seeking to obtain clean polycarbonate experiment, researchers at the same time use the curcumin and THCM.THCM is a form of curcumin, its chemical structure than curcumin more additional four hydrogen atoms.THCM retained the curcumin all structure and advantages of drug, but won't produce curcumin as a polycarbonate synthesis of monomer is not very good when the thick yellow.Scientific research personnel under the monitoring of ultraviolet-visible spectrometer, through selective reduction process, from curcumin derivative THCM, and through 13 c - NMR spectrum, to confirm the process.
When the end product of curcumin polycarbonate and finished TCHM polycarbonate synthesis, brooke 500 MHz nuclear magnetic resonance spectrometer immediately generate the corresponding 1 h-nmr spectrum.In the end, the research team succeeded in turn toxic bisphenol A polycarbonate plastic waste of renewable monomers equivalent polymer.Through further, infrared spectrum analysis to prove that the formation process of the carbonate compounds.The observation results also proved that the use of curcumin and THCM polymerization can be successfully.In addition, curcumin polycarbonate and THCM polycarbonate polymerization yield high, similar to that of bisphenol A polycarbonate polymerization yield, it enhances the curcumin as A precursor of the plastic product availability.
Of A plastic one like phenol production and circular economy in the future
The study takes the lead in trying to curcumin as bisphenol A sustainable alternative material for synthesis of polycarbonate.Of bisphenol A renewable alternative materials demand is the result of article mentioned in the first health and environmental risks.As a result, the new study goals include plastic, use of renewable energy production, and according to the circular economy principle, design of recycled consumer goods.
Brooke Avance series of nuclear magnetic resonance spectrometer is a key tool in polymer research and development work.This instrument provides a unique combination of probe, the researchers were able to quickly adapt to the new trend, and as mentioned in this article, on the molecular structure of the new type polymer for validation.
Circular economy aims to build a more sustainable social production and consumption model, it emphasizes the use of renewable energy and improve the material can be reused.Curcumin is not only A natural, renewable plastic precursor, and to use its production of bisphenol A polycarbonate to translate into high purity bisphenol A, for further processing and recycling.Therefore, we can use the sustainability of the curcumin advantage to help realize recycling economy.
Study leader acknowledged that, at present, the curcumin in large-scale plastic production cost is higher.However, they still advocate the consumers, producers and policy makers to give corresponding support, so as to help construction of A plastic one like phenol in the future.Enhanced environmental protection consciousness of plastic industry, consumers, in turn, affects the production process, to sustainable alternative materials, at the same time, to realize circular economy policy makers may through the formulation of relevant policies, reduce the corresponding cost of curcumin.
