| titleOfInvention | Novel synthesis technology of adipic acid (2-propyl heptyl) ester |
| abstract | The invention discloses a novel synthesis technology of adipic acid (2-propyl heptyl) ester. The technology comprises the following steps: (1) taking adipic acid and heptanol according to the molar ratio of 1:(2.3-2.5) as raw materials, and taking a catalyst with the mass of 0.18%-0.22% of the total mass of the adipic acid and heptanol, wherein the catalyst is a mixture of isopropyl titanate and tetrabutyl titanate with the ratio of 2:1; (2) taking adipic acid and heptanol according to the molar ratio of 1:(1.8-1.9) as raw materials, placing the raw materials into a reaction kettle, adding the catalyst, and heating for an reaction for 2-3 hours; (3) heating the reaction liquid in the step (2) to be at 200-220 DEG C, and adding the remaining heptanol for complete reaction to obtain a crude product; (4) performing water washing, decoloring, and filtering on the crude product to obtain the finished product of the adipic acid (2-propyl heptyl) ester. The novel synthesis technology provided by the invention can reduce production energy consumption, and hardly generates waste water with a high COD value, thereby meeting the requirement of environment protection. |
