羟基茚满麝香DDHI合成研究

２，６－二异丙基苯酚（ＤＩＰＰ）与异戊二烯（ＩＰ）反应生成羟基茚满麝香ＤＤＨＩ，用Ｃ－２催化剂，反应最佳条件为：ＩＰ与ＤＩＰＰ物质的量比为１．３０；Ｃ－２催化剂与ＤＩＰＰ的质量比为１．４０；反应温度为９５℃，产品收率高于文献［２］约１０个百分点以上，高于本院自制Ｃ－１催化剂的收率约４个百分点以上。在１０Ｌ玻璃反应釜中重复试验１２批次后，产品收率仍达到８０．９％，平均收率８０．０％。     

人造麝香DDHI模试研究

对２ , ６ － 二异丙基苯酚与异戊二烯合成人造麝香ＤＤＨＩ 进行了放大试验研究。最佳条件为： Ｃ－ ２／ＤＩＰＰ＝ １－４ （ ｗ／ｗ） ; ＩＰ： ＤＩＰＰ＝ １－３ （ ｍｏｌ／ ｍｏｌ） ; 反应温度为９５ ℃; 滴加时间（３ ～２－５） 小时, 平均收率达８８－５ ％ , 高于小试收率。生产中还应该考虑到初产品中的重组分含量来及时调整原料配比。发现ＤＤＨＩ的副产为新型抗氧剂, 可应用于ＰＰ 及ＳＢＳ 作抗氧化剂,废物的利用可降低ＤＤＨＩ 生产成本。

Characterisation of musk lime (Citrusmicrocarpa) seed oil

BACKGROUND: The seeds of musk lime (Citrus microcarpa) represent a substantial waste product of small‐scale citrus‐processing factories, as they constitute about 100.0 ± 3.2 g kg^?1 of the whole fruit and contain a considerable amount of crude fat (338.0 ± 11.3 g kg^?1). Thus the aim of the present study was to determine the physicochemical properties of this fat with a view to potential applications. RESULTS: The iodine and saponification values and unsaponifiable matter and free fatty acid contents of the freshly extracted oil were 118.0 g I₂ per 100 g oil, 192.6 mg KOH g^?1 oil, 22 mg g^?1 oil and 18 mg oleic acid g^?1 oil respectively. The oil had a Lovibond colour index of 33.1 Y + 1.1 B. Its fatty acid profile indicated that 73.6% of the fatty acids present were unsaturated. Linoleic (L, 31.8%), oleic (O, 29.6%) and palmitic (P, 21.4%) acids were the predominant fatty acids, existing mainly as the triacylglycerols POL (18.9%), PLL (13.7%) and OLL (11.9%). The melting and cooling points of the oil were 10.7 and ? 45.2 °C respectively. Electronic nose qualitative analysis of the oil showed the presence of volatile (aroma) compounds, although the concentrations of the more volatile compounds were lower than those present in the seeds. CONCLUSION: Musk lime seeds are a rich source of oil, which is unusual in having linoleic, oleic and palmitic acids dominating the fatty acid composition. This property should make the oil both relatively stable to thermal oxidation owing to the combined presence of oleic and palmitic acids (61.0%) and highly nutritive owing to its high concentration of unsaturated fatty acids (73.6%).
