{"title":"Production of Biodiesel from Waste Cooking Oil using A Zinc-Based Metal-Organic Framework (Zn-MOF) As Catalyst","authors":"Okpara Sergeant Bull, Sunday Monsuru Adewale, Eyu Okpa","doi":"10.14445/23939133/ijac-v11i1p101","DOIUrl":"https://doi.org/10.14445/23939133/ijac-v11i1p101","url":null,"abstract":"- Due to fossil fuel diminishing reserves, global warming, and high petroleum prices, there is a need to generate alternative, sustainable, renewable, and biodegradable biodiesel. In this paper, a zinc-based Metal-Organic Framework (Zn-MOF) was solvothermally synthesized, characterized and then used as a catalyst in place of the traditionally used toxic acids and bases as catalysts in biodiesel production. The Zn-MOF was synthesized using zinc nitrate hexahydrate, (ZnNO 3 ) 2. 6H 2 O as the source of metal ion (a Lewis acid), while benzene-1,4-dicarboxylic acid (BDCA) served as a ligand (a Lewis base). A mixture of dimethylacetamide (DMA) and H 2 O (1:1 ratio) functioned as solvent. In a clean and dry beaker, 0.297 g (0.999 mmol) of Zn(NO 3 ) 2. 6H 2 O was completely dissolved in 2 ml of distilled water. In another clean and dry beaker, 0.166 g (0.999 mmol) of BDCA was dissolved in 2 mL of DMA. Then, both solutions were mixed together and then transferred into a Teflon-lined autoclave. The Teflon-lined autoclave containing the mixture was put in an oven and heated at 150 °C for 24 h. After this period, the Zn-MOF was formed as colourless plate crystalline solids. The Zn-MOF remain unmelted even beyond 360 °C. Furthermore, the Zn-MOF was characterized by FTIR and powder X-ray diffraction. The FTIR shows the incorporation of the ligand into the Zn-MOF. The melting point and the powder X-ray diffraction results agree with the properties of MOFs in the literature. After that, the Zn-MOF was used as a catalyst in the transesterification of treated Waste Cooking Oil (WCO) for biodiesel production. The biodiesel was obtained by transesterification process at a temperature of 60 °C using a 1:5 molar ratio of oil to methanol. The biodiesel yield was 96%. The biodiesel diesel produced was physicochemically characterized. The analysis results revealed that the experimentally obtained values for viscosity, density, flashpoint, cloud point and pour point were 4.1 cSt, 821 kg/m³, 170 °C, below 0 °C and 2 °C, respectively. These values, when compared with standards (ASTM), were in agreement. The Zn-MOF recovered and recycled five times without degradation. Hence, it can be said that Zn-MOF is a good catalyst in the transesterification process of biodiesel production and can, therefore, replace the traditionally used toxic acids and bases.","PeriodicalId":13860,"journal":{"name":"International Journal of Applied Chemistry","volume":"103 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140484694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, a one-pot facile, more benign, less expensive and higher yield method has been used for the preparation of tris(4-bromophenyl)chlorosilane, which is a highly used precursor for the making of a rigid core carbosilane dendrimers. The reaction pathway for the synthesis of tris(4bromophenyl)chlorosilane is similar to the procedure followed for synthesising similar compounds in the literature but with differences in starting materials and modifications in the workup processes. The tris(4-bromophenyl)chlorosilane in this work was prepared by the dissolution of 1,4-dibromobenzene in dry ether at -76 °C, followed by the slow addition/stirring of n-BuLi. After 1 h of stirring, tetrachlorosilane was slowly added at temperature range of -70 to -75 °C. The reaction setup was allowed to stir further to room temperature for 24 h. The reaction was stopped, followed by a workup to obtain a colourless powder product with an 82% yield. The colourless powder was characterised by melting point (123.4 °C) and elemental analysis (Anal.
