为了研究肉桂酸酯类化合物在农作物上的应用活性，用2,4-二氯肉桂酸为起始原料合成出2,4-二氯肉桂酸二乙氨基乙醇酯的有机酸盐，并对其进行了核磁确定，同时对该产品的剂型进行了研究。结果表明，用其500倍液作用于花生、生姜和玉米时增产率分别达21%、16.7%和22.4%，说明该产品对几种农作物均具有较高的生物活性和增产性能。

In order to study the activity of cinnamate in crops, 2,4-dichloro-cinnamic acid ethyl ester was synthesis starting from 2,4-dichloro-cinnamic acid, and 2,4-dichloro-cinnamate was determined by 1H NMR. The dosage form of the product was researched. The results showed that, it had high promoted rate 21% on peanuts, 16.7% on ginger, 22.4% on corn with 500 times, it displayed that these compounds have high biological activity and production increasing performance.
