benzophenone造句
1. Synthesis process of benzophenone hydrazone is studied with benzophenone and 80%hydrazine as raw materials. Effects of material ratio, reaction time and concentration on aimed products are explored. 2. A new photoinitiator, 4-phenoxy benzophenone (PBZP), was synthesized and characterized using diphenyl ether and benzoyl chloride as raw material. 3. The degradation products of benzophenone are analyzed by GC-MS. A possible reaction pathway is proposed based on the analysis. 4. From this, the green synthesis route of benzophenone was defined. 5. In order to confirm this hypothesis, benzophenone was used instead of acetone . 6. This paper studied the energy transmission mechanism between benzophenone and 3,4-polyisoprene which were irradiated by high pressure Hg lamp. 7. Benzotriazole , o - hydroxyl benzophenone, salicylic acid and esters comprise several important types of ultraviolet - absorbents ( UAS ). 8. The results indicated that using benzophenone (BP) as photo-initiator, acrylamide as graft monomer, the polyacrylamide chain was grafted on the surface of membranes. 9. HALS are experimentally used in PVC films in this study. It is shown that thermostabilization and photostabilization functions of HALS are similar to those of benzophenone in PVC. 10. The p-chlorostyrene as the raw material is turned into 4-methyl-4'-vinyl benzophenone after Grignard process and hydrolyzed with 4-methyl-benzonitrile. 11. The organic compounds obtained from the first step of the thermal decomposition reaction were mainly benzoic acid, benzophenone, 9, 10 - anthraquinone, 1,3-diphenylisobenzofuran and so on. 12. This consistence shew that organic crystals at least like benzophenone grown from their undercooled melts could reflect their characteristic morphologies. 12. Wish you will loveand make progress everyday! 13. Active free radicals in the photochemical hydrogen abstraction reaction between benzophenone and aromatic amines have been studied systematically by combination of spin trapping reagents and ESR. 14. The kinetics of thiol-ene reaction is studied by Fourier Transform Infrared when benzoin dimethyl ether, benzoin ethyl ether, benzoin butyl ether, benzophenone and ITX were used as photosensitizer. 15. Benzoyl chloride was synthesized by the reaction of benzoic acid with SOCl2 and reacted with resorcinol to give 2,4-dihydroxy benzophenone, the yield was 79.4%. 16. Nanosized nickel based catalysts can be used to carry out the hydrogenation of styrol and benzophenone at normal temperature and pressure. 17. The maximum UV absorption wavelength of polymerizable photoinitiator shifted toward long wavelength, and the residues of light-cured were far less than benzophenone. 18. The organic compounds are mainly benzoic acid anhydride , benzophenone, and so on. 19. We investigated photoisomerization of the cinnamic acid derivatives resulting from the intramolecular T-T energy transfer from the covalently linked triplet benzophenone unit. 20. The effects of technical factors on photografting reaction of low - density polyethylene (LDPE) using benzophenone as photosensitizers were studied under air atmosphere.
