Process A
In Process A, 200.00 g of soybean oil and 200.00 g of water were combined in a 1 L beaker. This mixture was then reacted with 100.00 g of 30% sodium hydroxide solution at 90°C for 4 hours to produce soap. The resulting soap was filtered, and the residue was dried under vacuum at 100°C to a constant weight.
Process B
In Process B, 200.00 g of soybean oil and 200.00 g of water were mixed in a 1 L beaker and reacted with 100.00 g of 30% sodium hydroxide solution at 90°C for 4 hours to generate soap. The soap was then acidified by adding 135.00 g of 30% sulfuric acid solution, followed by stirring for 1 hour. The acidified mixture was transferred to a separatory funnel, where the top fatty acid layer was separated and washed three times with warm water (approximately 60°C). Next, a 30% sodium hydroxide solution, in an amount 110% of the stoichiometric requirement based on fatty acid content, was added dropwise to the fatty acid layer while stirring vigorously for 4 hours. The soap was then filtered and dried under vacuum at 100°C to a constant weight.
Process C
In Process C, fatty acids were first prepared using the same method as in Process B. These fatty acids were then dissolved in acetone at a mass ratio of 1:8 (fatty acid to acetone). A 30% sodium hydroxide solution, in an amount 110% of the stoichiometric requirement based on fatty acid content, was added dropwise to the fatty acid/acetone mixture, with vigorous stirring for 4 hours. The soap was obtained after filtration and dried under vacuum at 100°C to a constant weight.

This study presents a novel, efficient one-step method for the preparation of acrylated soybean oil (ASO). ASO was synthesized by directly reacting soybean oil (SO) with acrylic acid (AA) under the catalysis of BF₃·Et₂O.
1H NMR analysis revealed that the number of acrylate groups attached to each triglyceride molecule reached 3.09, corresponding to a double bond conversion of approximately 75.7%. The conversion of double bonds significantly increased with higher concentrations of acrylic acid and catalyst. Additionally, the reaction time played a crucial role in both the conversion and yield, with longer reaction times enhancing the likelihood of polymerization between AA and ASO. This work offers a simple and effective synthetic route for acrylating vegetable oils, providing a promising alternative for producing ASO-based macromonomers.

Biodiesel is commonly produced through the transesterification of vegetable oils using a homogeneous acid or base catalyst, such as H₂SO₄, NaOH, or KOH. In this study, biodiesel was synthesized from soybean oil using a MnCO₃/ZnO catalyst with varying Mn/Zn molar ratios, prepared via the co-precipitation method, and subcritical methanol as the reactant.
For the biodiesel production, a 500 mL stainless steel autoclave, equipped with a stirrer, internal cooling pipe, temperature sensor, and external heating jacket, was employed. The autoclave was capable of withstanding a maximum pressure of 10 MPa and a temperature of up to 573 K. During the typical transesterification reaction, soybean oil, methanol, and the catalyst were introduced into the autoclave, which was then heated to the desired temperature. The mixture was stirred at a constant speed of 200 rpm, and the reaction time started once the autoclave reached the set temperature. The pressure, which ranged from 1.8 to 3.2 MPa, was monitored using a pressure sensor. After the predetermined reaction time, the transesterification process was halted by circulating tap water through the internal cooling pipe and using a water bath. The autoclave was then opened, and the resulting product was analyzed to assess the conversion of triglycerides.
