Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 144978-35-8, Name is 1-Boc-D-Pyroglutamic acid ethyl ester, molecular formula is C12H19NO5, belongs to amides-buliding-blocks compound, is a common compound. In a patnet, author is Bhandari, Dhaka Ram, once mentioned the new application about 144978-35-8, Recommanded Product: 1-Boc-D-Pyroglutamic acid ethyl ester.
Synthesis of a novel beta-cyclodextrin-functionalized hydrophobically associating polyacrylamide named ASM was carried out using acrylamide (AM), cetyl dimethyl allyl ammonium bromide (SD-16) and modified beta-cyclodextrin (M-beta-CD) via free-radical copolymerization. Effective characterization methods, including FT-IR, H-1 NMR and TGA, were adopted to evaluate ASM. Influences of SiO2 nanoparticle (nanoSiO(2)) on ASM solution properties were evaluated. The results showed that the addition of nano-SiO2 significantly increased the temperature resistance, salt tolerance and shear resistance of the ASM solution. It was found that ASM/SiO2 composite had 1.5 times higher viscosity than ASM in the range of 25 -90 degrees C. The FT-IR data confirmed that the formation of hydrogen bond between silanol groups at surface of nano-SiO2 and amide group, hydroxyl group of M-beta-CD in ASM molecule contributed to the improved performance. What s more, viscoelastic test indicated that nano-SiO2 remarkably facilitated the crosslinks among polymer molecules and enhanced the elasticity of ASM/SiO2 composite. Based on the enhanced oil recovery tests, the oil recovery could remarkably enhance 10.08% for composite versus only 6.56% for ASM. (C) 2019 Elsevier B.V. All rights reserved.
