Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 71-44-3, Name is Spermine, molecular formula is , belongs to amides-buliding-blocks compound. In a document, author is Zhang, Shaohan, Computed Properties of https://www.ambeed.com/products/71-44-3.html.
The aminolysis of ethyl acetate was promoted significantly via continuous reaction in a tubular reactor. N-propylacetamide was thus synthesized without presence of solvent and catalyst. The optimum conditions were obtained as follows: the reaction temperature is 218 degrees C, the reaction pressure is 3.5 MPa, the molar ratio (ethyl acetate: N-propylamine) is 1:1, and the residence time is 350 min. Accordingly, the conversion of ethyl acetate is up to 94.8%. Furthermore, the kinetics of the rapid reaction stage (when the conversion of ethyl acetate is 20%-80%) can be expressed as lnk = -4629.44 1/T + 2.1366, and the apparent activation energy is E-a = 38489 J.mol(-1).

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 71-44-3, in my other articles.
