There were 17 same constituents in the two samples.The main constituents of them are decanal, dodecanal, 1-dodecanol.

二者相同的化学成分有17，是癸醛、十二烷醛、十二烷醇等。

Dodecanol abietate succinic anhydride was synthesized from abietic acid.The structures of products were characterized by spectrum of IR，HNMR and MS.

以枞酸为起点，合成了十二醇酯琥珀酸酐，用红外光谱、核磁共振波谱及质谱对中间产物及终产物进行了结构表。

It is possible to predict and controll the conversion rate of esterifications such as acrylic acid with dodecanol,tetradecanol and hexadecanol by this equation.

归方程在自变量的归范围内适用于丙烯酸与十二醇、十四醇、十六醇酯化转化率的预测和控制上。
