VC fatty acid ester compound and antioxidant properties

At the same time and space and common antioxidant BHT (2,6 ~ b t-butyl p-cresol) for comparative experiments. The results in Table 6. Table 6100 ~ C under the change of peroxide value of time,[link widoczny dla zalogowanych], h024487296l20Vr fatty acid ester l48l041519.5BHTl5ID4l72743 blank l1021J tear can be seen from Table 6 69Ii0 at 100 ~ C to maintain the same time, add products, peroxide value less than the oil sample added BHT and the blank,[link widoczny dla zalogowanych], and feel free to ask to increase the peroxide value growth is also slower, indicating that the fatty acid ester compound Vc is a good anti-oxidants 3 Conclusion lard prepared by esterification with methanol, fatty acid methyl ester compound,[link widoczny dla zalogowanych], yield 97.2 %. Concentrated sulfuric acid as the solvent and catalyst, v and composite fatty acid methyl ester exchange reaction carried out spiritus, vr compound synthesized fatty acid ester, the optimal condition for the (V): (composite fatty acids) as l: 1.2,[link widoczny dla zalogowanych], reaction temperature is 25 ℃, reaction time 26h, (thick so4): n (vc + complex fatty acids) is 1:0.15, the yield was 76% of the products tested showed that the antioxidant properties of fatty acids v complex spiritus is a good non-toxic antioxidant .
