The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Synthesis of a New Type of Star-Shaped Poly(2-alkyl-2-oxazolines) on the Basis of Sulfochlorinated Calix[8]arene》. Authors are Blokhin, A. N.; Razina, A. B.; Bursian, A. E.; Ten’kovtsev, A. V..The article about the compound:11-Bromoundecanoic acidcas:2834-05-1,SMILESS:O=C(O)CCCCCCCCCCBr).SDS of cas: 2834-05-1. Through the article, more information about this compound (cas:2834-05-1) is conveyed.
A new approach to the synthesis of sulfonyl chloride initiators with the calixarene core for the cationic polymerization of 2-oxazolines is developed. The kinetics of 2-ethyl-2-oxazoline polymerization with the synthesized octafunctional initiator at 100°C in sulfolane is studied. It is shown that the decelerated initiation of polymerization is observed in the system and the rate constant of chain propagation is kp = 1.20 x 10-3 L/(mol s). Using the cationic ring-opening polymerization of 2-alkyl-2-oxazolines initiated by calix[8]arene functionalized by sulfonyl chloride groups in the lower rim, star-shaped thermosensitive polymers are synthesized, and the mol. weight characteristics of the polymers are investigated. The critical micelle concentration of star-shaped poly(2-isopropyl-2-oxazoline) is determined (CCMC = 6.25 x 10-5 g/mL), and the solubilizability of the synthesized polymers is investigated using hydrophobic dye curcumin as an example.
Different reactions of this compound(11-Bromoundecanoic acid)SDS of cas: 2834-05-1 require different conditions, so the reaction conditions are very important.
