tributyl(hexadecyl)phosphanium bromide - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| Application | Decadecane tributylphosphorus bromide is a catalyst, used as a surface modifier for the thermal properties of palygorskite, an additive in water to improve the resistance of the epoxy anhydride matrix, and as a modifier for phenolic resin to improve thermal degradation. |
| Uses | Decane tributylphosphorus bromide can be used as a surfactant and also as a catalyst for organic synthesis. |
| production method | equimolar 1-brominated n-decane and tributylphosphine are reacted at 65 ℃ for 3 days, and the obtained solid product is recrystallized in hexane and dried in vacuum to obtain decadecyltributylphosphorus bromide with a yield of 68%. |
