Paragraph 0136-0138, (2017/04/11)
This invention generally relates to thermoregulation and temperature stabilization, thermal protection and insulation, and nucleating agents. In particular, in alternative embodiments, provided are organic phase change materials comprising diesters and alkanolamides. In alternative embodiments, provided are Phase Change Material (PCMs) compositions comprising diesters and alkanolamides, and methods for making and using them. In alternative embodiments, the Phase Change Material (PCMs) compositions are used for thermal energy management, including energy storage and/or temperature stabilization, in various applications such as building, automotive, packaging, garment and footwear, textiles, fabrics, synthetic fibers, foods, microcapsules and other energy storage systems.
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.
