benzene ring造句
1 The copious benzene rings and potential carboxylic acid groups in coal suggest that these transformations might not be too difficult. 2 The benzene ring is also seen in other compounds. 3 The synthesis methods of chalcone and benzene ring alkylation are discussed. 4 When the substituent at the benzene ring and the N atom of aniline, the HDAC inhibition activity is different from that of SAHA. 5 Alteration of two vibration modes of benzene ring of the drug shown by difference spectroscopy gives evidence of the insertion of benzene into acidic phospholipid bilayer. 6 There is the larger dihedral angle between benzene ring and nitro group, which is the common experimental phenomenon and has been clarified with the electronic theory in this paper. 7 Especially the benzene ring of polystyrene cation exchange resin varies slowly. Therefore the graphite degree of carbonized product of polystyrene cation exchange resin is getting low comparatively. 8 Oxidizing sidechainalkyl of benzene ring is one of the most important reactions in the organic synthesis. 9 The benzene ring of both resins is glowing into benzene fused ring structure with the carbonization temperature increasing. 10 Benzene ring in benzocrown ether has electron receptor effect can reduce complex ability to metal ions because of weakling the basicity of crown ether. 11 One of the hydrogen atoms in ammonia is replaced by a benzene ring. 12 PBZT is a rigid rod polymer, Its molecula chain is consisted by benzene ring and hybrid benzene ring. PBZT film is extruded from PBZT/MSA anisotropic solution. 13 The hydrophobic property of the resin has remarkably improved by adding the hydrophobic group of benzene ring to the molecular structure of the resin. 14 Membrane filtration technology emerged difficult to deal with some materials containing benzene ring in the printing and dyeing wastewater. 15 Owning to the high energy of C-H bond in benzene ring, benzene can be hardly oxygenated by common oxidants. 16 Synthesis and characterization of poly(amidoamine)(PAMAM) dendrimers are conducted by taking the benzene ring as nucleus. 17 These results showed that the change of end substituents X and side substituent Y of benzene ring in the molecules had important effects on mesogenic properties of these liquid crystalline compounds. 18 In recent years, more and more scientists modify the double bond or benzene ring of resveratrol to get higher activity, lower toxicity derivates. 19 Aromatic A hydrocarbon derived from, or characterized by the presence of the benzene ring. 20 In recent years, more and more scientists modify the double bond or benzene ring of resveratrol to get higher active, lower toxicity derivates. 21 The hexagonal structure in the center of the Paradox molecule is a Benzene ring. 22 The synthesis, properties and application of planar binuclear phthalocyanine and its derivatives, in which two phthalocyanine units share a common benzene ring, are described. 23 The enantioselectivity of N-dodecanoyl-L-proline-3,5-dimethyl- anilide is also good, but the basic line fluctuates strongly due to containing benzene ring in its molecular structure. 24 Results We obtained the epoxidation products of phenyl epoxy ethane. That with substituent on the benzene ring has higher yield, and that the substituent at 5-have higher yield than at 3-. 25 A biologically important organic phenol, having two hydroxyl groups attached to the benzene ring.
