用于固化环氧化物的催化剂
摘要：
本发明涉及式(I)的1，3-取代的咪唑鎓盐作为潜伏催化剂用于固化含有环氧基化合物的组合物的用途，其中R1和R3各自独立地是具有1-20个碳原子的有机基团，R2、R4和R5各自独立地是氢原子或具有1-20个碳原子的有机基团，R4和R5也可以一起形成脂族或芳族的环，X是pkB值小于13的阴离子(在25℃和1巴下在水或二甲基亚砜中检测)，n是1、2或3，但是咪唑鎓盐不包括乙酸1-乙基-2，3-二甲基咪唑输和乙酸1-乙基-2，3-二甲基咪唑嗡-乙酸配合物。
摘要（英）：

The invention relates to the use of 1, 3 substituted imidazolium salts of the formula (I), R1 and R3 independently representing an organic group having 1 to 20 C atoms, R2, R4, and R5 independently representing a H atom or an organic group having 1 to 20 C atoms, R4 and R5 also together being able to form an aliphatic or aromatic ring, X representing an anion having a pK B value of less than 13 (measured at 25 DEG C, 1 bar in water or dimethylsulfoxide), and n representing 1, 2 or 3, where 1-ethyl-2,3-dimethylimidazolium acetate and 1-ethyl-2,3-dimethylimidazoliumacetate-acetic acid complex are excluded as the imidazolium salt, as a latent catalyst for curing compositions comprising epoxy compounds.
