Triglyceride oils having unsaturated fatty acid substituents are modified to convert sites of unsaturation to C-2 to C-10 diesters. The resulting derivatives are characterized by thermal and oxidative stability, have low temperature performance properties and are environmentally-friendly. They have utility as hydraulic fluids, lubricants, metal working fluids and other industrial fluids. The triglyceride oils are most easily prepared via epoxidized vegetable oils which are converted to the diesters in either a one- or two-step reaction.

Os óleos do triglyceride que têm substituents unsaturated do ácido fatty são modificados para converter locais do unsaturation ao C-2 aos diesters C-10. Os derivatives resultantes são caracterizados pela estabilidade térmica e oxidative, têm propriedades do desempenho da temperatura baixa e são ambiental-amigáveis. Têm a utilidade como líquidos hidráulicos, lubrificantes, líquidos de funcionamento do metal e outros líquidos industriais. Os óleos do triglyceride são preparados o mais fàcilmente através dos óleos vegetais epoxidized que são convertidos aos diesters em um um ou à reação two-step.
