Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Research Paper (undergraduate) from the year 2024 in the subject Chemistry - Other, grade: A, , language: English, abstract: Tobacco processing industries generate a large volume of tobacco waste as a by-product during the production of tobacco products. These wastes are typically discarded through methods like incineration or burial. However, this discarded material still contains significant economic value that is often overlooked. One of the most valuable components of tobacco waste is its high nicotine content. Nicotine is a key raw material for a variety of products, including those in the pharmaceutical and personal care industries, particularly to produce hygienic products such as nicotine patches or e-cigarette liquids. Therefore, finding ways to extract and utilize the nicotine from tobacco waste could have both economic and environmental benefits. The extraction of nicotine from tobacco waste is an important issue, as it presents an opportunity to create a valuable resource for various industries, while also mitigating the environmental harm caused by the burning of tobacco waste. Incineration and burial contribute to air and soil pollution, which can have long-lasting negative impacts on the environment. By extracting nicotine from these wastes, industries can repurpose what would otherwise be discarded material, reducing waste and contributing to more sustainable practices. This experiment focuses on a simplified approach to nicotine extraction from tobacco waste using an alkaline extraction method. In this process, sodium hydroxide (NaOH) solution is used to break down the plant material and release nicotine. Following this, diethyl ether is employed for solvent separation to isolate the nicotine from the extract. To confirm the presence of nicotine, picric acid and methanol are added to the solution, inducing the formation of a picrate precipitate. The appearance of a colorless precipitate after cooling the mixture serves as a positive indicator of the presence of nicotine in the extract. This approach provides a relatively straightforward and effective method for extracting nicotine from tobacco waste, offering a potential pathway for repurposing this by-product into valuable resources while reducing environmental impact.…

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Research Paper (postgraduate) from the year 2024 in the subject Engineering - Chemical Engineering, grade: A, , course: Chemical Technology, language: English, abstract: Now biodiesel has become a long-term viable option while being a gentler-on-the-planet on the planet alternative to conventional fossil fuels, offering lessened release of greenhouse gases and biodegradability. The focus of this research is on the production of biodiesel from both used vegetable oil (UVO) and raw vegetable oils through transesterification, a process that converts triglycerides into fructooligosaccharide methyl esters using alcohol (typically methanol) and a catalyst. The research compares the efficiency, yield, and quality used to make biodiesel from used cooking oil and fresh vegetable oils, highlighting the economic and environmental benefits of utilizing waste oils. Key parameters such as oil reacting temperature, composition, free fatty acid content, catalyst type, and alcohol-to-oil ratio were analyzed to optimize biodiesel production. The results demonstrate that biodiesel derived from used vegetable oil presents a viable alternative with comparable fuel properties to that produced from raw vegetable oils while promoting waste recycling and cost-effectiveness. The findings of this research reinforce the possibilities of biodiesel as an alternative fuel and support its role in sustainable energy development.…
