DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Cellulose-tris(3,5-dimethylphenylcarbamate) (I) was prepd. by a reported method, and the structure was confirmed by IR spectroscopy and elemental anal. Then I was coated onto an aminopropylated mesopore spherical silica gel. The final product was used as the HPLC chiral stationary phase for the enantiosepn. of the novel herbicide ethoxyfen-Et. The enantiosepn. of ethoxyfen-Et on this stationary phase has been achieved for the first time. Mixts. of hexane and isopropanol were used as mobile phases. The effects of isopropanol concn. in the mobile phase on the retention and resoln. were investigated. With the decrease of the content of isopropanol in mobile phase, the resoln. factors increased. When the isopropanol concn. decreased to 1%, the resoln. factor was 3.95.Chemical with cas number 131086-42-5 also plays role. The structural features of the solutes that influence chiral sepn. are also discussed. .
