    • The invention includes a method of forming an alpha, beta-unsaturated compound. A carboxylic acid is mixed with an alpha-hydroxy acid or an alpha-hydroxy ester and is esterified to form an alpha-acyloxy derivative. The alpha-acyloxy derivative is transformed into an alpha, beta-unsaturated derivative. The invention additionally includes a process of forming an acrylate. Lactic acid or a lactic acid ester is reacted with a first portion of acetic acid in the presence of a first catalyst to produce the corresponding 2-acetoxy propionic acid or ester. A non-reacted portion of the acetic acid is recycled. The 2-acetoxy propionic acid or ester is transferred to a second vessel containing a second catalyst, and acetic acid is liberated from the 2-acetoxy propionic acid or ester to produce a corresponding acrylic acid or acrylate ester. The acid or ester is subsequently esterified by reaction with an alcohol to form a desired acrylate ester.
    • 本发明包括形成α,β-不饱和化合物的方法。 将羧酸与α-羟基酸或α-羟基酯混合并酯化形成α-酰氧基衍生物。 α-酰氧基衍生物转化成α,β-不饱和衍生物。 本发明还包括形成丙烯酸酯的方法。 乳酸或乳酸酯与第一部分乙酸在第一催化剂存在下反应,生成相应的2-乙酰氧基丙酸或酯。 将乙酸的未反应部分再循环。 将2-乙酰氧基丙酸或酯转移到含有第二催化剂的第二容器中,并从2-乙酰氧基丙酸或酯中释出乙酸,生成相应的丙烯酸或丙烯酸酯。 酸或酯随后通过与醇反应形成所需的丙烯酸酯而酯化。
