Ishag, Abd Elaziz Sulieman Ahmed; Abdelbagi, Azhari Omer; Hammad, Ahmed Mohammed Ali; Elsheikh, Elsiddig Ahmed Elmustafa; Hur, Jang-Hyun published an article on February 28 ,2019. The article was titled 《Photodegradation of chlorpyrifos, malathion, and dimethoate by sunlight in the Sudan》, and you may find the article in Environmental Earth Sciences.Application In Synthesis of Triacetonamine The information in the text is summarized as follows:
The potential of sunlight photolysis in remediation of pesticide-polluted soils in Sudan was studied. Chlorpyrifos, malathion and dimethoate, common pollutants, were exposed to sunlight over glass and soil surfaces with periodic samples drawn for GC and GC-MS anal. Photo-degradation followed a biphasic model. Alpha half-lives of direct photolysis over glass surface range between 1.99 and 9.36 days while the range in soil surfaces is 1.88-10.77 days. Resp. values for indirect photolysis with βcarotene are 0.96-2.40 days whereas for benzophenone are 0.38-2.37 days (not including malathion as starting material was completely lost after 3 days). Values for soil β-carotene sensitized photolysis are 0.85-4.02 days while resp. values for soil benzophenone sensitized photolysis are 0.88-3.74 days. Metrol. factors did not have a significant impact on photolysis rates. No photoproducts detected in direct photolysis. However, many photoproducts were detected on the indirect sets. Photo-degradation efficiency can be ordered as; benzophenone > β-carotene > direct exposure. In the experiment, the researchers used many compounds, for example, Triacetonamine(cas: 826-36-8Application In Synthesis of Triacetonamine)
Triacetonamine(cas: 826-36-8) is a member of piperidine. Piperidine is a key saturated heterocyclic scaffold found in several of the top-selling small molecule pharmaceuticals and natural alkaloids, with a diverse range of biological activities. Hence, continuous efforts have been made to develop convenient methods to prepare piperidine derivatives.Application In Synthesis of Triacetonamine
