The competitiveness of the biodiesel industry may be improved by adding value through co-products and integration with the oleochemical industry, especially for novel products such as biolubricants, a product of increasing world demand. In this study the synthesis of biolubricants from soybean oil was evaluated using transesterification, epoxidation and oxirane ring opening reactions. Water, 2-ethylhexanol and their mixtures were used to obtain hydroxyl-rich and/or ether-type branched molecules. All chemical modifications were monitored by Nuclear Magnetic Resonance (1H NMR) and evaluated through the physicochemical properties of the products. Several potential biolubricant samples were synthesized with viscosities at 40 °C ranging from 26.6 to 99.6 cSt, viscosity index from 26 to 139, densities at 20 °C from 0.925 to 0.964 g/cm3, and pour points from −3 to −12 °C. From these results, a proposal of a feasible industrial process for the production of biolubricants from soybean oil is presented, consisting of 16 units, of which 15 may be integrated with an existing biodiesel plant.

用大豆油生产生物润滑剂:与当前生物柴油行业整合工艺的研究

通过副产品的增值和与油脂化工的整合,可以提高生物柴油行业的竞争力,尤其是对于世界需求日益增长的新产品,如生物润滑剂。在这项研究中,使用酯交换,环氧化和环氧乙烷开环反应评估了从大豆油中合成生物润滑剂。使用水,2-乙基己醇及其混合物来获得富含羟基和/或醚型的支链分子。所有化学修饰均通过核磁共振监测(11 H NMR),并通过产物的理化性质进行评估。合成了几种潜在的生物润滑剂样品,其粘度在40°C下为26.6至99.6 cSt,粘度指数为26至139,在20°C下的密度为0.925至0.964 g / cm 3,倾点为-3至-12° C。根据这些结果,提出了一种由大豆油生产生物润滑剂的可行工业方法的建议,该方法由16个单元组成,其中15个可与现有的生物柴油工厂整合。
