In this paper, the non-ionic intermediate was prepared by op-10 and epoxy chloropropane; the quaternary ammonium salt intermediate was prepared by triethylamine and epoxy chloropropane; the op-10/cationic surfactant composite asphalt emulsifier was synthesized by reacting with non-ionic intermediate, quaternary ammonium salt intermediate and N-octadecyl propylene diamine. The effect of synthesis conditions and the prescription on the emulsifying property, surface activity and using performance of emulsifier was studied, a new way for the preparation of the composite asphalt emulsifier was explored.

A novel fluorinated quaternary ammonium salt cationic surfactant N,N,N-trimethyl-2-[[4-[[3,4,4,4-tetrafluoro-2-[1,2,2,2-tetrafluoro-1-(trifluoromethyl)ethyl]-1,3-bis(tri-fluoromethyl)-1-buten-1-yl]oxy]-benzoyl]amino]-iodide (FQAS) was synthesized successfully, and its structure was characterized by FTIR,1H-NMR,19F-NMR, and MS. The surface activities of FQAS and the effect of temperature, electrolyte, and combination with hydrocarbon surfactant were investigated. The results showed that FQAS exhibited excellent surface activity and combination with hydrocarbon surfactant.

The Stability

The paper deals with instability of solutions of quaternary ammonium permanganates, QMnO4 (Q = tetraethyl-, tetra-1-propyl-, tetra-1-butyl-, tetra-1-pentyl-, tetra-1-octyl-, and cetyltrimethylammonium), in dichloromethane and presents the rate constants and activation parameters of the reduction of permanganate. Attention was paid to the properties of colloidal Mn(IV) intermediate. The stability of the solutions depends markedly on the quaternary ammonium salt used.
