Özet:

 

Ester derivatives of 9, 10-dihydroxystearic acid were  prepared and characterized.  The processes involved were epoxidation  of oleic acid, opening of the oxirane ring, and esterification.  The  structures of the products were confirmed by FTIR, 1H- and  13C-NMR. The low-temperature properties of each product were  characterized using the pour point test.  Other physical properties,  such as flash point and viscosity, were also determined.  The results  show that desirable low temperature properties were obtained for  triester 7, with a pour point value of -25 °C. It was discovered that  increasing the chain length of the mid-chain ester and the branching  at the end-chain ester had a positive influence on low-temperature  properties of the triesters.  These products could plausibly be used  as biobased industrial materials in biolubricants, surfactants, or  fuels.
