With the breakdown of ricinoleic acid through the cracking technique, either in the thermal or thermo-catalytic form, compounds of interest for green chemistry, such as heptaldehyde and undecylenic acid, can be obtained. These supplies are envisioned since they are building block chemicals. Therefore, the influence of operational conditions on the cracking process was evaluated using a 2 ³ experimental design, including temperature, water, and catalyst, with the aim of improving the yield of heptaldehyde and undecylenic acid supplies from castor oil, inedible oil. The operating conditions used in the cracking process were: temperature of 500, 525, and 550 °C, water fractions of zero, 12.5%, and 25%, and catalyst fractions of benzoyl peroxide of zero, 0.55%, and 1.1%. The analysis suggests that the central point utilizing thermo-catalytic cracking demonstrates superior operational conditions as they generate an average of 78.5% bio-oil, 21.97% heptaldehyde, and 17.25% undecylenic acid, with 12.5% water and 0.55% catalyst at a temperature of 525 °C.

蓖麻油热裂解和热催化裂解生产庚醛和十一碳烯酸

通过热或热催化形式的裂解技术分解蓖麻油酸,可以获得绿色化学感兴趣的化合物,例如庚醛和十一碳烯酸。这些供应品是可预见的,因为它们是积木化学品。因此,使用 2³ 实验设计(包括温度、水和催化剂)评估了操作条件对裂解过程的影响,目的是提高从蓖麻油(非食用油)中供应的庚醛和十一碳烯酸的收率。裂解过程中使用的操作条件为:温度为 500、525 和 550 °C,水分数为零、12.5% 和 25%,过氧化苯甲酰的催化剂分数为零、0.55% 和 1.1%。
