トルエンのクロルメチル化反応によるパラキシレンクロリドの合成  [in Japanese] Synthesis of p-Xylenechloride from Toluene by Chloromethylation  [in Japanese]

p-Xylenechloride which can be converted to terephthalic acid for polyester use by oxidation was prepared from toluene by chloromethylation (by treatment with formalin, HCI, & ZnCI_2). The best results were followed : Toluene 2.2 mol, Formalin 1.2 mol, HCI speed passed 440ml/min, Time 2 hrs, Temp. 70°±2°C, Yield 68.5%.
