The reasonable dewaxing method of prickly ash seed oil should be:① The low wax crude manufacture oil can use surfactant to dewax;② If the wax content is relatively high,progressive dewaxing can be adapted to reduce oil lose in the process;③ To the oil that need alkali refining,the wax can be eliminated with the free fatty acid in the process of alkali refining.

脱除花椒籽油中蜡质的合理方法应是：①含蜡量相对较低的精制粗油可选用表面活性剂法脱蜡；②当含蜡量相对较高时，为降低脱蜡过程中油的耗损率可选用分步脱蜡法脱蜡；③需进行碱炼的油，可在碱炼过程中将蜡质与游离脂肪酸一并除去。

We used phospholipid, Epikuron 200, and cholesterol as material to prepare liposome formulation, and discuss the effect of liposome formulation which contain phospholipid and cholesterol or the mix of ionic surfactants such as stearylamine, dicetyl phosphate and nonionic surfactant such as Tween 80. For the three group that physical properties of drug entrapment efficiency, particle size and stability of formulation on day 0, 14, 21 and 30 were respectively compared, and further, we were sieve out optimization of formulation.

我们利用Epikuron 200之磷脂质，以及胆固醇作为制备微脂粒处方之材料，并探讨处方不加或分别加入表面修饰剂stearylaminem与dicetyl phosphate以及非离子界面活性剂Tween 80对处方之影响，且比较此三组微脂粒的物理性质，包含包埋率、粒径大小以及处方在第0、14、21、30天之安定性的变化，进一步筛选出理想之处方。

The reason may be that complex formed by rhodium and halide was difficult to produce the catalytic active species. Therefore halide ion was the poison for the rhodium catalyst in hydroformylation of olefins in ionic liquid. The effect of double long chain cationic surfactant (DCMAB, dicetyl dimethylammonium bromide) on selective hydrogenation of cinnmaldehyde catalyzed with RuCl3·x H2O/TPPTS was studied.

进一步的研究表明在使用有良好反应活性的两种催化剂HRh3 、Rh_2进行催化反应时，向体系中加入含有卤离子的化合物时将使反应活性大大降低，而且随着卤化物加入量的增加，催化剂的活性迅速下降，这是卤离子可能和金属铑作用使它难于生成催化活性物种，进一步证明卤素离子是引起催化剂活性下降的极其重要的因素。

In this liquid membrane system,P291〔diphosphoric acid〕and TRPOare used as synergistic mobile carrier,N205 as surfactant,liquid paraffin as film-strengthening agent,sulphonated kerosene as solvent,and (NH4)2CO3 solution as inner phase agent.

用P291〔二磷酸〕、TRPO协同流动载体，N205为表面活性剂，液体石蜡作膜的增强剂，磺化煤油作溶剂，(NH4)2CO3作内相试剂的乳状液膜体系，迁移富集钍。
