Arnold Alberts in 1930 found this ester to condense easlly with ammonta to form a diamlde which melted at 226°C. With the hope of forming substitute diamides having melting points of wide variance. easily obtained and easily purified. work was begun upon condensation of the ester with various aliphatic Amines. Ethyl Sulfone-bis-Acetate is a clear viscous liquid with the formula ILC,OtC-CIL-SO.-CIL-COtCJL
Arnold Alberts 在 1930 年发现这种酯很容易与 ammonta 缩合形成 diamlde,在 226°C 熔化。希望形成具有广泛差异熔点的替代二酰胺。容易获得且容易纯化。在酯与各种脂族胺缩合后开始工作。
乙基砜-
双乙酸酯是一种透明粘稠液体,分子式为 ILC,OtC-CIL-SO.-CIL-COtCJL。它对皮肤无刺激性。不挥发。并且不吸
水。酯与各种胺的下列缩合得到这些熔点:N-戊基二胺,170°C;异戊基,152°C;正丁基。192°C;异丁基,130°C;正庚基,180°C;正丙基,174°C。至今仲碳原子上的胺基团和仲胺不缩合。但进一步的研究可能会找到浓缩它们的方法。
