Abstract
Process for the catalytic hydrogenation of vegetable oils wherein the oil is placed in contact with molecular hydrogen in the presence of a metal catalyst, and the process is performed in the absence of water or in the presence of a quantity of water equal to or less than 5:1 with respect to the weight of the metal catalyst and at a temperature equal to or less than 50° C.
Claims21
A process for the selective conversion of polyunsaturated fatty acids into monounsaturated fatty acids of triglycerides present in vegetable oils, with a trans-isomerization degree of less than 50% of the formed monounsaturated fatty acids, wherein the oil is placed in contact with molecular hydrogen in the presence of a metal catalyst, wherein said process is performed in the absence of water or in the presence of a quantity of water equal to or less than 5:1 with respect to the weight of the metal catalyst and at a temperature from 18 to 3° C. and for a duration of from 5 minutes to 6 hours.
A process for the selective conversion of polyunsaturated fatty acids into monounsaturated fatty acids of triglycerides present in vegetable oils selected from sunflower oil, oils from Brassicaceae or Cardoon oils, with a trans-isomerization degree of less than 50% of the formed monounsaturated fatty acids, the said conversion being performed using a metal catalyst and in the absence of water or in the presence of a quantity of water equal to or less than 5:1 with respect to the weight of the metal catalyst and at a temperature equal of 18 to 3° C. and for a duration of from 5 minutes to 6 hours.
