二十五碳烷

In addition nC〓, nC〓, two isomers of C〓 sterene and three isomers of C〓 isoprenoid hydrocarbons were also identified from aliphatic fraction of pyrolyzed product at 200℃. After pyrolyzed at 300℃, the main aliphatic hydrocarbons were normal alkanes ranged from C〓 to C〓, with C〓 as the main peak and C〓 as the second main peak. Meanwhile, pristane, phytane and C〓 sterane were also detected. In the pyrolysates at 400℃ and 500℃, the content of saturated hydrocarbons decreased, the range of normal alkanes distribution became narrow and the main peak was nC〓. Low concentration of C〓-C〓 steranes was detected and the content of C〓-C〓 increased more.

在200℃热模拟产物饱和烃馏分中除检测出两种长链烯烃外，还检测到正十九碳单烯烃、正三十五碳双烯烃、两个碳二十八甾烯的同分异构体和三个C〓类异戊二烯烷烃化合物同分异构体。300℃模拟产物饱和烃主要为正烷烃，正烷烃的碳数分布范围为C〓-C〓，以C〓为主峰、C〓为次主峰；另外，样品中还检出姥鲛烷、植烷和C〓甾烷等化合物。400和500℃热模拟产物中的饱和烃含量下降，正烷烃系列碳数分布范围变窄，主峰碳后移至C〓，检测到低浓度的C〓-C〓甾烷系列化合物，另外，C〓-C〓藿烷系列化合物含量进一步增加。

They were acetic acid, benzaldehyde, n caproic acid, methyl pentadecanoic methyl ester, glycerin, benzoic acid,,9 octadecadienoic methyl ester, squalane, stearic acid and oleic eicosyl ester.

The results showed that the unsaturated fatty acid content of pecan kernel oil was 89 0%,and 13 kinds of unknown components such as nonadecaol,8 hexyl pentadecane,10 methyl eicosane,11,14 eicosadienoic acid,1 bromo 8 heptadecyne,9 hexyl heptadecane,tetracosane,13 docosenoic acid,1 bromo 7 nonadecyne,15 tetracosenoic acid,hexacosanoic acid,7 hexyl ei...

研究结果表明：山核桃仁油中的不饱和脂肪酸 w =89 0 %，未知成分是十九醇、8 己基十五烷、10 甲基二十烷、11，14 二十碳二烯酸、1溴 8 十七炔、9 己基十七烷、二十四烷、13 二十二碳烯酸、1 溴代 7 十九炔、15 二十四碳烯酸、二十六酸、7 己基二十烷、二十七烷共 13种，其中13 二十二碳烯酸、15 二十四碳烯酸、十九醇等具有较强的生理活性和药用价值

With intermediates 1,ω-hexadecanediol and ω-bromo pentadecanol as starting materials,ω-bromo hexadecanoic acid and ω-bromo octadecanoic acid were prepared in four and seven steps of reactions separately.

分别以1，ω-十五烷二酸和1，ω-十六烷二酸为原料，各经过四步有机反应，制备了ω-碘代十六烷酸及含十四、十五、十六碳原子的ω-溴代直链脂肪酸；再以中间产物15-溴代十五烷醇、1，ω-十六烷二醇为原料，各经过四步、七步有机反应，制备了ω-溴代十六烷酸及ω-溴代十八烷酸。

Result 16 kinds of fatty acids were separated from Anak chicken muscle and identified. Among them, 7 kinds fatty acids, including lauric acid, myristic acid, pen-tadecanoic acid, palmitic acid, margaric acid, stearic acid and eicosanoic acid, were saturated fatty acids and its content accounted for 38.55% of the total fatty acids; 9 kinds fatty acids, including 11-teteadecenoic acid, 9-hexadecenoic acid, 9-vaccenic acid, 9,12-octadecadienoic acid, 6,9,12-octadeca-trienoic acid, 11-eicosenoic acid, 10, l3-eicosenoic acid, 7,10, 13-eicosatriennoic acid and 5,8,11,14-arachidonic acid, were unsaturated fatty acids, and its content accounted for 61.45% of the total fatty acids.

结果］安卡鸡肌肉中共分离和鉴定出16种脂肪酸，其中饱和脂肪酸7种，包括月桂酸、豆蔻酸、十五烷酸、棕榈酸、十七烷酸、硬脂酸和花生酸，其含量占总脂肪酸的38.55%；不饱和脂肪酸9种，包括11-十四碳烯酸、9-十六碳烯酸、9-十八碳烯酸、9，12-十八碳二烯酸、6，9，12-十八碳三烯酸、11-二十碳烯酸、10，13-二十碳二烯酸、7，10，13-二十碳三烯酸以及5，8，11，14-二十碳四烯酸，共含量占总脂肪酸的61.45%。
