| Boron trifluoride catalysis is used to achieve properties differentiated from those that can be achieved with aluminum chloride for a given feedstock. They are most often used with lower cost aromatic feedstocks to make so-called C9 resins, where aluminum chloride catalysis has limited application. As a result, boron trifluoride has a somewhat undeserved reputation for products with a strong odor. |

They are most often used with lower cost aromatic feedstocks to make so-called C9 resins, where aluminum chloride catalysis has limited application. As a result, boron trifluoride has a somewhat undeserved reputation for products with a strong odor. 对某一给料（或反应物），三氟化硼催化(反应)是用来获得有别于氯化铝(催化) 反应所能达到的性质。它们（这两种催化剂）经常和芳香族给料（或反应物）一起来制备所谓的C9树脂，因为氯化铝催化（反应）本身对这些反应是有一定局限性的。结果是，因产品有强烈的气味，三氟化硼获得了本不应获得的（坏）名声。 |
