Preparation And Inhibiting Capabilities Of Amino Acid Species Clean Inhibitors

The problem studies preparation and inhibiting capabilities of amino acid species clean inhibitors. Clean inhibitors combine's inhibitors with clean chemistry. Clean Chemistry can decrease or perish use and produce of material, catalyst, solvent, reagent, production, subsidiary production those are bad for health, community security and environment. Amino acid is the basic composing substance of protein. Because of the small molecule structure, the stability of amino acid is very good, it can either utilize in acidity, neuter and atmosphere medium abroad,it is a kind of good performance The combination of inhibitor and Clean Chemistry is another item breach of Clean inhibitor. The amino acid organic matter took in the acid water solution medium the steel and iron corrosion inhibitor research receives the various countries' scholar to pay attention continuously. The combination of inhibitor and Clean Chemistry is another item breach of Clean Chemistry.The problem adopting siphon theory hydrolyzes protein flotsam to manufacture AASI,and using dispatch showing spectral luminosity law determine amino acid contents;high temperature combining CO2 corrosion resisting inhibitor PASP。The new hydrolyzing and the synthetic method, and this synthetic product serves as the corrosion inhibitor have not been seen in the history reports, which is simple, the production rate is high , and the production is clean chemistry substance.The problem experiment gets across the weightlessness, SEM, electrochemistry tests system studying the inhibiting capabilities,inhibiting law,inhibiting mechanism of amino acid species clean inhibitors by the numbers, and applying infrared spectra (IR) , Raman spectrum to have carried out superficial characteristics on the PASP structure. As for the inhibition performance research of PASP,the SEM of PASP adsorption film outside in examination are shown for the first time, this provides the important basis for the explanation of PASP inhibiting mechanism.; as for the inhibition performance research of PASP, the Raman spectrum of adsorption state on the metal surface of the product ,as well as the contrast of Raman and Infrared are shown for the first time.The problem experiment result indicates: The system research on inhibition performance reflected that AASI could protect the X65 carbon steel well even in the HCl and CO2 solution with serious mineralization and strong causticity. The inhibition performance would be better depending the increase of its concentration, and the best inhibition performance would be got at the concentration of 0.735g/L,0.1 g/L, moreover, the inhibition performance would be weakened when the concentration was exceeded the optimum value. Testified by divides all luminosity law that the available components of inhibitor hydrolyzed from protein flotsam is amino acid species substance. Obtains the best hydrolysis condition with the orthogonal experiment, whose craft is simple, consumes time and material quantity to reduce, and the efficiency is high. Composing PASP under the best technological conditions, getting across IR and the Raman spectrum affirms appearance of target outcome characteristic function group- brother's ammonia, Acid amides, carboxyl .etc. In the PASP SEM picture, observation assumes film state of PASP, adsorbing intensely outside slice base.
