One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Recommanded Product: 143878-29-9, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 143878-29-9, Name is Methyl 4-acetamido-5-chloro-2,3-dihydrobenzofuran-7-carboxylate, molecular formula is C12H12ClNO4
High acid crudes contain large amounts of naphthenic acids (NAs), which lead to severe corrosion in oil refinery equipment and serious environmental problems. The goal of this study is to develop a non-catalytic supercritical methanol (scMeOH) route for effective deacidification of NA mixtures and high acid crudes (Laguna and Bachaquero-13). Various reaction parameters, including temperature, pressure, reaction time, and NA-to-methanol ratio, are explored to find effective reaction conditions for reducing the total acid number (TAN) of the mixtures. Almost complete TAN reduction of naphthenic acid (96.9%) is achieved at 400 C, 10 MPa, and 3 h. The reaction in scMeOH at 400 C, 30 MPa and 1 h is effective in the TAN reaction of high acid crudes (93.6-94.0%). The chemical composition of the liquid products obtained under the different reaction conditions, analyzed using gas chromatography-mass spectroscopy, show that esters are the most abundant species, indicating that esterification with scMeOH is the major reaction pathway. The most recalcitrant NA species, which remained after the reaction, are found to be 2-ethyl-2,3,3-trimethyl-butanoic acid and 2,3-dimethyl-2-(1-methylethyl)-butanoic acid. This is attributed to the branched hydrocarbons located near the carboxylic acid groups, which hinder the access of methanol molecules.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Recommanded Product: 143878-29-9, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 143878-29-9, in my other articles.
