| Synthesis of Glycol Ketals of 2,4,ω-Trichloroacetophenone |
| YANG Chun long; JIANG Mu geng （Department of Applied Chemistry; Nanjing Agricultural University; Nanjing 210095; China） |
| Abstract：Glycol ketals of 2,4,ω trichloroacetophenone were synthesized with the starting materials of 1,3 dichlorobenzene, chloroacetic acid, glycols etc. by acyl chloridation, acylation and condensation reaction. Effects of catalysts and dehydrolysis time of condensation reaction on synthetic yield were studied in particular. The synthetic products were confirmed by infrared spectrography and gas chromatography/mass spectrography. |
| Key words：trichloroacetophenone; glycol; ketal |
