aliphatic alcohol-
Fifty - one and nineteen compounds were detected respectively from the volatile extracts of the fossils from miocene leaves of metasequoia glyptostroboides and early cretaceous seed cone of pityostrobus spp. by gas chromatography - mass spectrometry ( gc - ms ) analysis
摘要採用氣相色譜質譜聯用分析技術從中新世水杉葉片和白堊紀松型球果兩種裸子植物化石中分別鑒定了51個和19個揮發性成分，類型涉及烷烴、烷烯、烷醇、長鏈脂肪酸及其酯、鄰苯二甲酸酯、菇類和芳香族化合物。A super acylation catalyst, 4 - dimethylamino pyridine ( dmap ), was prepared and used to synthesize cholesteryl ester compounds. four kinds of cholesteryl ester compounds such as cholesteryl p - alkoxyl benzoate, cholesteryl dicarboxylate, cholesteryl lumequeic ester and coattail - like cholesteryl ester were synthesized by acylation method and super acylation catalyst method. chemical structures and liquid crystal behaviors of the synthesized samples have been characterized by using element analysis, ftir, dsc and polarized microscopy with a hot stage
本文合成了高效酰化催化劑4 -二甲基氨基吡啶（ 4 - dimethylaminopyridine ， dmap ） ，採用酰氯化法和高效酰化催化劑法分別合成了對烷氧基苯甲酸膽甾醇酯、對稱脂族二羧酸膽甾醇酯、烯酸膽甾醇酯及燕尾型膽甾醇酯四類膽甾醇酯衍生物，並進行了化學結構和液晶性能的表徵。When it comes to fats and cholesterol, a lot of people automatically want to keep their distance, because all they can think of is weight gain, heart disease, high blood pressure, and other ill effects
認識脂肪一族提起脂肪及膽固醇，很多人都會拒之千里，因為它總被認為是肥胖、心臟病、高血壓等問題的罪魁禍首。Aliphatic alcohol ehter alkyl capping series products have many particular properties, such as, low foam, strong lipophilicity, strong acid - base stability, good emulsification, low pour point, little viscosity change, chlorinated stability, heat resistivity and good property of anti - coking
脂肪族醇醚的烷基封端系列產品具有很多獨特的性質，如泡沫低、新油性強、酸堿穩定強、乳化能力好、流動點低、粘度變化小，氯化穩定性、耐熱性、抗結焦性能力好。Current thoughts on the phosphatidylinositol transfer protein family
磷脂酰肌醇轉移蛋白質家族的研究進展Phenyl group introducing to cholesteryl ester molecules can enhance the phase transition temperatures of the liquid crystals and their stability. an increase in the chain length for cholesteryl dicarboxylate samples reduced stability of liquid crystal phases. while coattail - like structures on the ester group of the molecules have an adverse effect to form cholesteryl liquid crystal phase
化學結構對液晶性的影響表現為：分子中引入苯環剛性結構可以提高液晶的相變溫度和穩定性；脂族二羧酸膽甾醇酯中脂肪鏈的長度增加會降低液晶的穩定性；而末端含有燕尾結構則對液晶態的形成產生不利影響。En 1791 surface active agents. fatty alkyl dimethyl amine oxides. determination of the amine oxide content
