Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 931-40-8, is researched, SMILESS is O=C1OCC(CO)O1, Molecular C4H6O4Journal, IOP Conference Series: Materials Science and Engineering called Investigation on the effect of ultrasonic-assisted transesterification for green synthesis of glycerol carbonate from crude glycerol, Author is Lo, P. K.; Leong, S. Y.; Tan, C. Y., the main research direction is investigation effect ultrasonic assisted transesterification green synthesis glycerol carbonate; crude glycerol.Safety of 4-(Hydroxymethyl)-1,3-dioxolan-2-one.
The present work demonstrates the utilization of ultrasonic-irradiation for synthesis of glycerol carbonate (GC) with direct use of crude glycerol (C.Gly) and di-Me carbonate (DMC). This transesterification reaction was catalyzed by calcium oxide (CaO) and the effect of ultrasonic-assisted transesterification reaction was studied. In order to verify the contents of C.Gly, the C.Gly obtained from biodiesel production plant was characterized and the results showed that C.Gly consists of 71.21%weight/weight glycerol, 16.01%weight/weight of moisture, 7.10%weight/weight of methanol, 2.76%weight/weight of ash, 3.60%weight/weight of soap and 10.02%weight/weight of matter organic non-glycerol (MONG). Subsequently, effects of reaction temperature, reaction time, molar ratios of reactants and catalyst loading on C.Gly conversion and GC yield have been investigated. The highest yield of GC (95.41%) was attained with 9 mol% of CaO catalyst loading, 3:1 molar ratio of (DMC:C.Gly) at 70°C for 90 min. The yield of GC was observed to rise with all the reaction parameters till the optimum conditions obtained. Moreover, the yield of GC obtained from ultrasonic-assisted was compared with the conventional-heating method done in the previous study. It was noticeable that the yield of GC obtained via ultrasonic-assisted was found to be 51.44% better than conventional-heating transesterification. In conclusion, the production of GC via ultrasonic-assisted transesterification shows better feasibility than that of the conventionalheating method.
