Xylene is used in the laboratory to make baths with dry ice to cool reaction vessels, [17] and as a solvent to remove synthetic immersion oil from the microscope objective in light microscopy. [18] In histology, xylene is the most widely used clearing agent. [19] Xylene is used to remove paraffin from dried microscope slides prior to staining.
Plastic recycling is the processing of plastic waste into other products. [1] [2] [3] Recycling can reduce dependence on landfills, conserve resources and protect the environment from plastic pollution and greenhouse gas emissions. [4] [5] [6] Recycling rates lag behind those of other recoverable materials, such as aluminium, glass and paper.
While most thermoplastics can, in principle, be recycled, PET bottle recycling is more practical than many other plastic applications because of the high value of the resin and the almost exclusive use of PET for widely used water and carbonated soft drink bottling. [62] [63] PET bottles lend
This plastic bucket has been used as an open-air flowerpot for some years. Photodegradation has made it brittle, causing part of it to break off when the bucket was moved. In polymer chemistry, photo-oxidation (sometimes: oxidative photodegradation) is the degradation of a polymer surface due to the combined action of light and oxygen. [1]

The p-xylene is then separated out in a series of distillation, adsorption or crystallization and reaction processes from the m-xylene, o-xylene, and ethylbenzene. Its melting point is the highest among this series of isomers, but simple crystallization does not allow easy purification due to the formation of eutectic mixtures.
Polymer degradation is the reduction in the physical properties of a polymer, such as strength, caused by changes in its chemical composition.Polymers and particularly plastics are subject to degradation at all stages of their product life cycle, including during their initial processing, use, disposal into the environment and recycling.
