| 摘 要： | 以活性白土、磷钨酸等为催化剂进行了松香催化裂解试验，并以活性白土为催化剂进行松香裂解反应条件及裂解产物组成的研究。结果表明：活性白土和磷钨酸的催化性能较强，反应2 h后可使松香酸值分别降至1.20 mg·g－1和2.07 mg·g－1；活性白土催化裂解松香的工艺条件为温度220 ～ 240 ℃、催化剂用量5.0% ～ 10.0%、反应时间1.0 h；在此反应条件下得到的裂解产物经气相色谱/质谱（GC/MS）分析表明是各种芳香类化合物的混合物，主要由萘、吲哚、吡啶和菲类等物质组成；松香裂解反应除了松香脱羧反应外，同时伴随着大量碳—碳键和碳—氢键的断裂和重排。图1表5参9 |

| Abstract: | Catalytic cracking of rosin with activated clay,phosphotungstic acid hydrate,phosphotmolybdic acid hydrate,zeolite molecule sieve and silicotungstic acid hydrate was studied,and reaction conditions along with chemical compositions of the cracked products from activated clay were analyzed with gas chro-matography-mass spectrometry(GC/MS).Results showed that with a 1.0-2.0 h reaction time,activated clay reduced the acid value of the products to 1.20 mg.g-1,whereas phosphotungstic acid hydrate reduced the acid... |
