???? CONTENT COVERED IN THE CLASS ???? ✓ In this class, we will talk about Organic Chemistry reactions with a focus on Enem questions. We will talk about the reactions of: Esterification Acid and Basic Hydrolysis of Ester Transesterification Saponification ENEM 2021) The simple act of not throwing used cooking oil directly into the trash or down the sink drain can contribute to reducing environmental pollution. But what to do with vegetable oil that will no longer be used? There is no ideal disposal model, but a simple alternative has been to reuse it to make soap. For this, in addition to the oil itself, water and caustic soda are necessary. (UNICAMP) Recently, a real “fatberg” was found, an iceberg of fat weighing around 15 tons, in the sewage pipes of a region of London. This “fatberg”, resulting from the improper disposal of fats and oil used in frying, could be reused in the production of: (ENEM 2019) One of the chemical recycling techniques for the polymer PET [polyethylene terephthalate] generates methyl terephthalate and ethanediol, according to the reaction scheme, and occurs through a transesterification reaction. Compound A, represented in the reaction scheme, is a) methane. b) methanol. c) methyl ether. d) ethanoic acid. e) ethanoic anhydride. (ENEM 2012) One of the methods for producing biodiesel involves the transesterification of soybean oil using methanol in a basic medium (NaOH or KOH), which must be carried out in the absence of water. The figure shows the reaction scheme for biodiesel production, in which R represents the different hydrocarbon chains of the fatty acid esters. The absence of water in the reaction medium is necessary for: ???? SUBSCRIBE TO THE CHANNEL - https://bit.ly/3zY1x21 ???? Did you like the video? Leave your LIKE! ????
