    • A low temperature process for preparing an aromatic acid having formula (I), said process comprising reacting an aromatic aldehyde having formula (II) with a gas having an oxygen content of 1 to 100 weight percent, based on the total weight of the gas, at a temperature of about 20 °C to less than 100 °C in the presence of the supported Group VIII metal catalyst, and a solvent having a flash point greater than 95 °C and/or a melting point less than 55 °C, provided that the flash point of the solvent is greater than the reaction temperature, wherein R and R are independently selected from the group consisting of hydrogen and a C1-C8 linear, branched or cyclic alkyl group. The process of the invention yields an aromatic acid in excellent yield, and (i) does not involve the use of deleterious oxidizing agents; (ii) is essentially free of by-products; and (iii) is accomplished at a temperature of less than 100 °C.
    • 用于制备具有式(I)的芳族酸的低温方法,所述方法包括使具有式(II)的芳族醛与基于气体总重量的1至100重量%的氧含量的气体反应, 在负载的第VIII族金属催化剂的存在下,在约20℃至小于100℃的温度和闪点大于95℃和/或熔点小于55℃的溶剂中,提供了 溶剂的闪点大于反应温度,其中R 1和R 2独立地选自氢和C 1 -C 8直链,支链或环状的烷基。 本发明的方法得到优异的收率的芳香酸,(i)不涉及有害氧化剂的使用; (ii)基本上不含副产物; 和(iii)在小于100℃的温度下完成。
