  不饱和长链羧基甜菜碱和羟基磺基甜菜碱的合成，表征和性能

  摘要：

  不饱和长链羧基甜菜碱和羟基磺基甜菜碱分别由不饱和十八烷基叔胺与氯乙酸钠和3-氯-2-羟基丙烷磺酸钠反应合成。这两个甜菜碱的结构通过红外光谱和1 H-NMR光谱表征。两个甜菜碱的Krafft点均低于0°C，等电点的pH分别为8.2和8.0。表面张力（γ CMC）在临界胶束浓度（CMC）下进行测量，以研究在50°C下pH分别等于4.0、6.5和10.0时所制备化合物的表面活性。同时，合成了相应的饱和甜菜碱并进行比较。在非极性尾导致稍高的CMC双键和下γ CMC。尽管在非极性尾部的双键，不饱和甜菜碱的CMC略高于饱和甜菜碱，但对于低Krafft点，不饱和甜菜碱的应用范围比相应的饱和甜菜碱的应用范围更广。CMC和Г CMC的四个甜菜碱增加，但PC 20随着pH值的增加而降低。总体而言，pH对这四个甜菜碱性能的影响不是很明显。

  A silane of the formula (I) containing at least one aliphatic amidine group- or guanidine group-containing alkoxy group, to a method for producing same, to conversion products thereof, and to the use thereof as a catalyst in curable compositions, in particular based on silane group-containing polymers. The silane of the formula (I) is largely odorless and non-volatile at room temperature. The silane accelerates the hydrolysis and condensation reaction of silane groups very effectively without impairing the storage stability of silane group-containing polymers. Additionally, the silane is very tolerable in silane group-containing compositions, whereby such compositions are not prone to separate, migrate, or evaporate the catalyst.
