摘要： A method for synthesizing 4,4-dihalogen-2-(dialkylamino)methylene-3-oxy-alkylbutyrate and its derivatives has acts of: (a) providing N,N-dialkylamino-alkyl-acrylate in a reaction vessel; (b) adding organic alkali, organic solvent and multiple molecular sieves into the reaction vessel; (c) mixing N,N-dialkylamino-alkyl-acrylate, the organic alkali, the organic solvent and the molecular sieves; and (d) adding 2,2-dihalogen-acetyl-chloride into the reaction vessel and allowing a synthetic reaction of 2,2-dihalogen-acetyl-chloride and N,N-dialkylamino-alkyl-acrylate to obtain 4,4-dihalogen-2-(dialkylamino)methylene-3-oxy-alkylbutyrate. The molecular sieves are able to remove water efficiently to prevent materials in the reaction vessel from undergoing side reactions or changing chemical properties. Furthermore, the molecular sieves are able to adsorb chloride to avoid polymerization reactions for improved yield.

摘要： A container assembly has a raw-material container and a product-collection container, which are heat resistant and pressure resistant and have graduations formed on a sidewall thereof and a joint protruding therefrom. The product-collection container is detachably mounted on the raw-material container and communicates with the raw-material container through the joint. Since the raw-material container has graduations, an amount of raw materials can be consistently added in each batch, therefore, conditions of sublimation such as pressure, temperature or the like do not require adjustment and may just be monitored to ensure maximum yield is attained. Therefore, a sublimation procedure is simple, saves time and decreases product costs. Since, the product-collection container has graduations, an amount of product can be observed easily by the graduations and the product is easily removed without removing impure byproducts. Therefore, purity of the product can be increased.
摘要翻译：容器组件具有耐热和耐压的原料容器和产品收集容器，并且具有形成在其侧壁上的刻度和从其突出的接头。产品收集容器可拆卸地安装在原料容器上，并通过接头与原料容器连通。由于原材料容器具有刻度，因此可以一批添加一批原料，因此，升压条件如压力，温度等不需要调整，可以进行监控，以确保达到最大的收率。因此，升华程序简单，节省时间，降低产品成本。由于产品收集容器具有刻度，因此可以容易地观察到一定量的产品，并且容易地除去产品而不除去不纯的副产物。因此，可以提高产品的纯度。
