2,2-bis(4-aminophenyl)hexafluoropropane is allowed to react with potassium thiocyanate and bromine to obtain 2,2-bis (5-amino-4,6-benzothiazolyl)hexafluoropropane, which is allowed to further react successively with potassium hydroxide and hydrochloric acid to obtain 2,2-bis(4-amino-3-mercaptophenyl)hexafluoropropane, which is a novel compound applicable as a curing agent for a fluorine-containing elastomer having CN groups as cross-linkable groups.
将 2,2-双(4-氨基苯基)六氟丙烷与硫氰酸钾和溴反应,得到 2,2-双(5-氨基-4,6-苯并噻唑基)六氟丙烷,再将其先后与氢氧化钾和盐酸反应,得到 2.2-双(4-氨基-3-巯基苯基)六氟丙烷、2,2-双(4-氨基-3-巯基苯基)六氟丙烷,这是一种新型化合物,可用作具有 CN 基团作为可交联基团的含氟弹性体的固化剂。
