A novel polymerizable hydrophobic monomer 1-(4-dodecyloxy-phenyl)-propenone (DPP) was synthesized by esterification, Frise rearrangement and Williamson etherification; then, the obtained DPP was copolymerized with 2-(acrylamido)-dodecanesulfonic acid (AMC12S) and acrylamide (AM) initiated by a redox initiation system in an aqueous medium to enhance oil recovery (EOR). AM/AMC12S/DPP (PADP) was characterized by FT-IR, 1H NMR spectroscopy, environmental scanning electron microscopy (ESEM), DSC-TG, fluorescent probe, core flood test, etc. Results of ESEM and fluorescent probe indicate that hydrophobic microdomains and associating threedimensional networks were formed in the aqueous solution of PADP. Results of DSC-TG demonstrated that long carbon chains, aromatic groups and sulfonic groups were incorporated into the PADP polymer, which can lead to a significant increase of the rigidity of molecular chains. Performance evaluation of experiments showed superior properties in regard to temperature-tolerance, shear-tolerance and salt-tolerance. In the Sandpack Flooding Test, PADP brine solution showed a significant increase in EOR at 65°C because of its high thickening capability. All these features indicate that PADP has a potential application in EOR at harsh conditions.

A novel anionic polymerizable surfactant sodium (5-acryloyl-2-(dodecyloxy) phenyl) methane sulfonate has been synthesized from phenol, acrylic acid and bromododecane by esterification, Frise rearrangement, sulfomethylation reaction and Williamson etherification. The parameters of the micellar behaviors are as follows: The CMC was 150 ppm at 40 °C; The surface absorption amounts Γm was 3.208 × 10-6 mol m-2; The molecular areas Am was 0.550 × 10-18m2 at the interface of air-water respectively; The aggregation number (N agg) at C = CMC of this surfactant was 12. A novel anionic polymerizable surfactant sodium (5-acryloyl-2-(dodecyloxy)phenyl) methane sulfonate has been synthesized from phenol, acrylic acid and bromododecane by esterification, Frise rearrangement, sulfomethylation reaction and Williamson etherification. The surfactantsynthesized was phenyl ether, and wasn't hydrolyzed in acidicor alkalic condition.

Previously it was found that 4-hydroxybenzaldehyde is a competitive inhibitor of GABA transaminase. Here 3-chloro-1-(4-hydroxyphenyl)propan-1-one (9), a 4-hydroxybenzaldehyde analogue, was found to inactivate potently the enzyme in a time-dependent manner. α-Ketoglutarate prevented the enzyme from inactivation, suggesting that the inactivation occurs in its active site. Several experiments indicated that the inactivation is irreversible. This study provides a novel strategy for the design of more effective inhibitors.
