异丁醛

【用途一】
用于制橡胶硫化促进剂和防老剂、异丁酸等
【用途二】
GB 2760一1996规定为允许使用的食用香料。主要用以配制焦糖、香蕉和各种水果型香精。
【用途三】
异丁醛的用途不如正丁醛广泛。工业上主要是加氢生产异丁醇。异丁醇在某些方面可作为正丁醇的代用品。异丁醛与甲醛经加成反应生成羟基三甲基乙醛，再加氢生成新戊二醇，用作清漆、树脂、纤维和润滑剂的原料；异丁醛与尿素反应制得的肥料能缓慢释放出氮；此外，也用作氨基酸、维生素等药物的中间体。羰基合成法按比例同时得到正丁醛和异丁醛，消费平衡的情况仍然是异丁醛供过于求，极大量异丁醛被当作燃料利用。
【用途四】
合成泛酸、缬氨酸、亮氨酸、纤维素酯、香料、增塑剂、树脂及汽油添加剂。也用于制造硫化促进剂和防老剂、异丁酸等。
