The present invention provides methylene beta-ketoester monomers, methods for producing the same, and compositions and products formed therefrom. In the method for producing the methylene beta-ketoesters of the invention, a beta-ketoester is reacted with a source of formaldehyde in a modified Knoevenagel reaction optionally in the presence of an acidic or basic catalyst, and optionally in the presence of an acidic or non-acidic solvent, to form reaction complex. The reaction complex may be an oligomeric complex. The reaction complex is subjected to further processing, which may be vaporization by contact with an energy transfer means in order to isolate the beta-ketoester monomer. The present invention further compositions and products formed from methylene beta-ketoester monomers of the invention, including monomer-based products (e.g., inks, adhesives, coatings, sealants or reactive molding) and polymer-based products (e.g., fibers, films, sheets, medical polymers, composite polymers and surfactants).
本发明提供亚甲基β-酮酯单体、生产亚甲基β-酮酯的方法以及由此形成的组合物和产品。在生产本发明亚甲基 β-酮酯的方法中,可选择在酸性或碱性催化剂存在下,也可选择在酸性或非酸性溶剂存在下,使 β-酮酯与甲醛源在改良的克诺文纳格尔反应中反应,形成反应络合物。反应复合物可以是低聚复合物。反应复合物需进一步处理,可通过与能量传递装置接触进行蒸发,以分离出 β-酮酯单体。本发明进一步提供了由本发明亚甲基 β-酮酯单体形成的组合物和产品,包括以单体为基础的产品(如油墨、粘合剂、涂料、 密封剂或反应成型)和以聚合物为基础的产品(如纤维、薄膜、片材、医用聚合物、复合聚 合物和表面活性剂)。
