Microplastic defines as a tiny plastic particle that has a size of less than 5 mm and is ubiquitous in the environment. Due to the tiny size, this microplastic adversely affected the environment, notably aquatic life via ingestion, choking, and entanglement. This microplastic is arduous to degrade as it takes a thousand years due to the properties of plastic itself and consequently remains in nature. In dealing with microplastic issues, this paper reflects the occurrence, impact, toxicity, and degradation methods of microplastics in the environment including phys., chem., and biol. treatments. Here, the phys. treatment methods include incineration treatment, UV, and photocatalytic. The incineration process contributes to environmental pollution due to the release of toxic gases into the atm. In addition, chem. treatments for plastic waste are the degradation process involving chem. additives such as ethylene glycol (EG), nano-magnesium oxide (MgO), diethylene glycol (DEG), and calcium or zinc (Ca/Zn) stearate as a catalyst. These treatments depend on the chems. that can affect human health and the ecosystem. The biodegradation treatment using bacterial and fungal species can consume the microplastic without disrupting the surrounding environment and biota. It includes recent findings on the biodegradation of microplastic under aerobic and anaerobic conditions. Thus, biodegradation can be considered the best option to degrade microplastic as green and sustainable technol. In the experiment, the researchers used many compounds, for example, 2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6Application In Synthesis of 2,2′-Oxybis(ethan-1-ol)).
2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Application In Synthesis of 2,2′-Oxybis(ethan-1-ol)
