-
Paragraph 0050-0052, (2019/07/01)
The invention discloses a method for synthesizing 1,9-decadiene. The method sequentially comprises the following steps: adding carboxylic acid and 1,10-decadienol into a reaction container, heating the container until the 1,10-decadienol is dissolved, adding a catalyst, carrying out an esterification reaction at 120-200 DEG C, and collecting water evaporated in the esterification reaction; continuously heating the container to 300-350 DEG C after no water is produced in the esterification reaction, carrying out a reaction for 5-8 h, and evaporating and collecting a mixed solution of 1,9-decadiene and carboxylic acid; and respectively post-processing the mixed of 1,9-decadiene and carboxylic acid to obtain carboxylic acid and 1,9-decadiene respectively. The method for preparing 1,9-decadiene is efficient, economical and green, and meets industrial production requirements.
