樣，Krytox 157 FS 潤(rùn)滑劑不溶于大多數(shù)常見(jiàn)有機(jī)溶劑。 它也是不可燃的。 脫羧在加熱到約 170 °C (338 °F) 以上時(shí)發(fā)生，并在 200 °C (392 °F) 時(shí)變得劇烈。 形成的產(chǎn)品似乎是一種混合物，但主要是 Krytox 氟化油的加氫封端形式。 在水的存在下，其堿金屬鹽的脫羧發(fā)生在較低溫度下，并產(chǎn)生基本上純的以氫封端的聚合物。Like the other Krytox™ fluorinated oils, Krytox 157 FS lubricant is insoluble in most common organic solvents. It is also nonflammable. Decarboxylation occurs on heating above about 170 °C (338 °F) and becomes vigorous at 200 °C (392 °F). The product formed appears to be a mixture, but is mainly a hydro-endcapped version of Krytox fluorinated oil. The decarboxylation of its alkali metal salts in the presence of water occurs at lower temperatures and yields essentially pure polymers end capped with hydrogen.
