A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 19845-69-3, Name is 1,6-Bis(diphenylphosphino)hexane, molecular formula is C30H32P2. In a Patent£¬once mentioned of 19845-69-3, Application In Synthesis of 1,6-Bis(diphenylphosphino)hexane
A hydroxy containing double four-quaternary phosphonium cationic antibacterial agent and its preparation method (by machine translation)
A hydroxy containing double four-quaternary phosphonium cationic antibacterial agent and its preparation method, which belongs to the technical field of quaternary phosphonium salt compound. The antibacterial agent structure is as follows: [HO – R – P+ (Ph)2 – (CH2 )x – P+ (Ph)2 – R – O – Q – O – R ‘ – P+ (Ph)2 – (CH2 )y – P+ (Ph)2 – R ‘ – OH] ¡¤ 4 X- Wherein R and R ‘ is selected from C4 – C10 alkoxy phenyl, phenyl; x, y separately taking 4 – 10 integer; Q is – (CH2 )z – Or – C2 H4 – (O – C2 H4 )m -, Z taking 4 – 10 integer, m taking 1 – 5 integer; X is a halogen compound. The invention can be through the reaction of the hydroxyl group with other compounds in the main chain is embedded in the material in order to achieve of the material is modified, the expansion of the antibacterial agent of the potential to use the range at the same time solves the possibility of overflow, antibacterial aging long, and in the reaction process is not influenced by temperature.
