This invention relates to a method for prolonging the life time of storage of paste tung oil with rosemary antioxidant, which adds the rosemary antioxidant-0.02-0.3% that of paste tung oil in the oil with the optimum match of 0.05-0.2%. In order to increase the dissolving speed of the antioxidant in the oil and increase the production efficiency, one portion of which can be added in the plant oil of 2-3 portions with the saturated fatty acid oil as the master, such as palm oil and rape oil to be heated to 90-130deg.C for 20-80 minutes then to be added into the paste tung oil after the antioxidant is fully dissolved to reduce the oxidation of paste tung oil and prolong the stored time of the oil.
Description
technical field [0001] The invention belongs to the technical field of oil processing, and in particular relates to a method for prolonging the storage life of tung oil. Background technique [0002] The development and production of biodiesel is of great significance to the protection of the environment, the conservation of energy resources, and the implementation of sustainable development strategies. Jtropha curcas L., also known as Jatropha curcas, is a plant in dry and hot valleys, and its seeds have high oil content. Tung oil or modified tung oil can be used as biodiesel for various diesel engines, and is superior to domestic No. 0 diesel in key technical indicators such as flash point, freezing point, sulfur content, carbon monoxide emission, and particle value. But tung oil contains a large amount of polyvalent unsaturated fatty acids, which are easily oxidized by oxygen in the air, causing deterioration and corruption, making the storage time of tung oil and modifi...
