    • PURPOSE: A method and storage are to inhibit the coloring, precipitation and polymerization of alkylamino(meta)acrylate. CONSTITUTION: For handling alkylamino(meta)acrylate in contact with stainless steel, the stainless steel is to indicate Ra value specified in JIS B0601 as less than 1.6 m at the surface, and the gas portion of the container is to have the moisture of 0.1% or molecular oxygen concentration of less than 10v% in excess of 0. Under the above conditions, the concentration of (meta) acrylic acid in alkylamino(meta)acrylic acid in alkylamino(meta)acrylate may be maintained at less than 0.1w% even at 40°C to inhibit polymerization, precipitation and coloring of the compound.
    • 目的:一种方法和储存方法是抑制烷基氨基(甲基)丙烯酸酯的着色,沉淀和聚合。 构成:为了处理与不锈钢接触的烷基氨基(甲基)丙烯酸酯,不锈钢将JIS B0601规定的Ra值表示为小于1.6μm,容器的气体部分的水分为0.1 %或分子氧浓度小于10v%超过0.在上述条件下,烷基氨基(甲基)丙烯酸烷基氨基(甲基)丙烯酸中的(间)丙烯酸的浓度可以保持在小于0.1w% 甚至在40℃下抑制化合物的聚合,沉淀和着色。
