ABSTRACT. 3,3-(Butane-1,4-diyl)bis(1,2-dimethyl-1H-imidazole-3-ium)bromide ([BDBDMIm]Br) is easily used as an efficient and recyclable ionic liquid for the synthesis of bis coumarinyl methanes in the presence of a catalytic amount of ceric ammonium nitrate (CAN) under grinding. All reactions are performed in the absence of solvent in excellent yield during short reaction time. Furthermore, the ionic liquid can be reused and recovered for several times without loss of activity. This method provides several advantages such as simple work-up, environmental friendliness and shorter reaction time along with high yields. All of synthesized compounds were characterized by infrared spectroscopy, 1 H and 13 C nuclear magnetic resonance spectroscopy and elemental analyses.

In recent years, there has been a significant interest from both domestic and international researchers in ionic liquids as they are recognized as environmentally friendly solvents and catalysts. From 5-hydroxymethylfurfural (HMF), a substrate derived from carbohydrate, various important compounds particularly the 2,5-dimethylfuran can be synthesized because it could be used as a biofuel and valuable substance. Furan derivatives such as 5-alkoxymethylfurfural, 2,5-furandicarboxylic acid, 5-hydroxymethylfuroic acid, bis-hydroxymethylfuran and 2,5-dimethylfuran have significant applications in the fields of fuel and polymers. This paper presented the preparation of 8 ionic liquids containing Brønsted acid and Lewis acid site, intending to utilize them as catalysts for converting carbohydrates into 5-hydroxymethylfurfural (HMF). Several factors affecting the performance of HMF were investigated, including the type and catalyst loading, temperature, solvent, and reused. The results showed that 1,4-bis(4-sulfobutyl)-DABCO-1,4-diium tetrachloroaluminate (IL1) exhibited potential as a catalyst for the synthesis of HMF from fructose. This reaction was conducted at a temperature of 100℃ for 5 min with the yield of approximately 60% when using [CholineCl][Citric acid] deep eutectic solvent. This catalyst, IL1/[CholineCl][Citric acid], was successfully recovered and reused for four times. This demonstrated the efficacy of various ionic liquids as catalysts for the synthesis of HMF from fructose. Further study on this catalyst is needed for the application in the producing fuel precursors derived from carbohydrates on an larger scale.

The synthesis of vinyl benzoate via transesterification of vinyl acetate with benzoic acid was investigated by a carbon-supported palladium catalyst. The results showed that Pd (5 wt %)/C catalyst presented good catalytic and reusable performance instead of mercuric salts of strong acids. The conditions of the transesterification reaction for achieving high yields of vinyl benzoate were explored. The optimized conditions are as follows: reaction temperature, 80 o C, reaction time, 10 h, catalyst dosage, 4.0 wt % of reactants, and benzoic acid/vinyl acetate molar ratio, 1:11, respectively, and the yield of vinyl benzoate was 85.7% with the purity of 98.3%. Meanwhile, the prepared Pd/C catalyst could be recycled five times without significant decrease in activity after separating from the product mixture, and the vinyl benzoate yield is still more than 81%. Furthermore, the eco-environmental synthetic method offers great potential for the industrial scale synthesis of vinyl benzoate.
