- Method for synthesizing ethylene glycol distearate in absence of solvent at ordinary pressure
-
The invention discloses a method for synthesizing ethylene glycol distearate in the absence of a solvent at ordinary pressure. In the presence of a solid acidic catalyst, the ethylene glycol distearate is prepared under certain technological conditions with ethylene glycol and stearic acid as raw materials. According to the method disclosed by the invention, the ethylene glycol distearate product can be synthesized at high efficiency in the absence of the solvent at ordinary pressure, wherein the acid value of the product can be less than 5 at least, and the acid conversion rate of the product can reach over 97%. The method disclosed by the invention is simple and highly-efficient, convenient and feasible to operate, safe and environment-friendly, and free of toxicity pollution and recovery problem of the solvent and has better generalization and application value.

- Esterification of free fatty acids (Biodiesel) using nano sulfated-titania as catalyst in solvent-free conditions
-
Nano sulfated titania was tested as catalyst for esterification of free fatty acids, specially methanolic and ethanolic esterification of stearic acid (biodiesels). Factorial design evidenced a positive effect of reaction temperature, amount of catalyst, and solvents on ester conversion. This nano-sized sulfated titania has been prepared by a sol-gel hydrothermal process. This prepared sulfated titania showed high catalytic activity in direct esterification of fatty acids as well as benzoic acids with various alcohols and phenols under solvent-free conditions. This method is of great value because of its environmentally benign character, easy handling, high yields, convenient operation, and green. FT-IR studies are shown that the catalyst can be reused for acylation without loss of catalytic activity.
