查询词典 propanoic acid

Under normal temp., PVF2 has a fine corrosion resistance to many organic solvents like halogen, halogenated hydrocarbon, strong oxidant, boiling acid and alkali UHMWPE has a fine corrosion resistance to inoxidable acid (dilute sulfuric acid, nitric acid and large concen-tration hydrochloric acid, phosphorus acid, hydrofluoric acid, formic acid and acetic acid), ammonia, amine and various alkali and salty solutions. Both materials cant resist the corrosion of strong oxidable acid.

The results showed that the irradiation treatment in the dose of 2.0-8.0kGy is not significantly effective to the contents of total sugar, crude protein and crude fat in walnut powder. The content of crude fiber in irradiated walnut powder increased, but not significantly. The irradiation had barely change on the contents of the lauric acid and myristic acid, and non-significant effects on the contents of palmitic acid, palmitoleic acid, stearic acid, leinoleic acid, arachidic acid and linolenic Acid. However, the irradiation contributed to significant increase in the content of oleic acid with the irradiation dose. When irradiation dose reached 8.0kGy, the content of oleic acid had an increase of 4.3%. Irradiation will not change the sensory index of walnut powder much when irradiation dose is lower than 8.0kGy.

The level in stage four and stage five was lower than the level in stage three.

Result 5 compounds in Hickory nut oil were identified, and they were linoleic acid, oleic acid, linolenic acid, palmitic acid and stearic acid, and their contents were 63.48%, 19.90%, 11.96%, 3.31% and 1.35% resp. The fatty acid ratio of n-6 to n-3 was 5.31, which was close to that of recommended by China (4-5):1. The ratio of saturated fatty acid, monounsaturated fatty acidand polyunsaturated fatty acids in Hickory nut oil was 1:4.3:16, the content of polyunsaturated fatty acids was slightly higher, but it mainly contained linoleic acid and a-linoleic acid, which were inevitable fatty acid to human body.
