摘　　要：采用正交试验设计,研究了偏三甲苯在V-Ti-P-O系表面涂层催化剂的作用下,经固定床气相催化氧化制备偏苯三酸酐。催化剂裁体为φ5mm内核无孔金刚砂球。By method of orthogonol design, preparation of trimellitic anhydride by pseudocumene catalytic oxidation in vapor phase at stationary bed with V-Ti-P-O coating catalyst was studied. The carrier of the above catalyst is nonporous carborundum ball (φ5mm).
