N-(6-methyl-2-pyridine)-amino-methylene-diethyl malonate was produced by condensation reaction of 2-amino-6-methyl pyridine with ethoxymethylene diethyl malonate under optimal conditions that n(2-amino-6-methyl pyridine)∶n(ethoxymethylene diethyl malonate) is 1∶1.3, reacting time 45 min and temperature 130 ℃,the yield of this reaction was 96%,which was 6% higher than that of literature.

在250℃的反应温度下，分别以二苯醚、石蜡油和邻苯二甲酸二乙酯为热载体进行成环反应，得到4-氧-7-甲基-1，8-萘啶-3-羧酸乙酯的收率分别为88.6%、56.3%和61.2%，确定二苯醚为最佳热载体，并发现反应温度对产率的影响最大，原料配比次之，反应时间基本无影响。

The optimum conditions for making microspheres were obtained via orthogonal experiment with adsorptive capacity as the index as follows: the mass fraction of water phase is 2%(ratio between starch and β-cyclodextrin is 1:2), 110 mL oil, 3.3 g Span60, 6.6 g Tween60, 15 mL water, 18 mL assistant surfactant, 0.07 g metaphosphoric acid trisodium salt. The microspheres were characterized by microscope and the average particle size is about 329.3 nm with productive rate of 41%.
