The illustration, taken from one theoretical point of view, gives the type of model construction that can be achieved. In conclusion, the media community is invited to accept the challenge associated with the general mandate of sociologists to contribute to the theory, in this case by building theoretical sound models for understanding the place of the media community in society.

Its reduction reaction with NaBH4 carrying out. Obtained 2,3-trimethylene-1,2,3,4-tetrahydropyrido[2,3-d] pyrimidin-4-one – this three-component coupling of a carbonyl, an amine and a hydrophosphoryl compoud leads to α-aminophosphonates, phosphorous acid-formaldehyde; aldehydes in three component system; minomethylphosphonic acid synthesis based on kabachnik-filds reaction. 2,3-trimethylene-3,4-dihydropyrido[2,3-d] pyrimidin-4-one 35% da product obtained. The reason of low reaction yield was studied. Structures were confirmed using IR and 1H NMR spectroscopies. Obtained product reduced using NaBH4 and 2,3-trimethylene-1,2,3,4-tetrahydropyrido[2,3-d] pyrimidin-4-one synthesis was carried out with high yield. 2,3-trimethylene-1,2,3,4-tetrahydropyrido[2,3-d] pyrimidin-4-one and respective aminophosphonic acids were synthesized in three component system with high yield.
11.06.2023 Volume 2 Issue 6 View more DownloadNowadays, creation of waste-free technology, rational use of existing raw materials is one of the urgent issues in industrialized countries. Butadiene is used in many fields due to its unique properties. Butane and butene mixtures contained in natural crude oil waste were isolated and butadiene was obtained based on extractive distillation. To solve these problems, this study proposes new improvements: The extractive distillation section is modified with intermediate heating and the classical columns are replaced by a dividing wall column (DWC) using a heat pump. Rigorous simulations were performed in Aspen Plus for a typical ED process. DWC was found to reduce the energy intensity of the classical distillation section of the BASF process by 54.8% and reduce total annual costs by 29.9%. In addition, the intermediate reboiler reduces the energy density of the ED section by 8.3%, while reducing the CAPEX cost of the system due to the need for a smaller recycle compressor
