Secondary amide di-quaternary ammonium salt type hydroxypropyl sodium sulfonate asphalt emulsifier and preparation method thereof

The invention discloses a secondary amide di-quaternary ammonium salt type hydroxypropyl sodium sulfonate asphalt emulsifier and a preparation method thereof, wherein the secondary amide di-quaternary ammonium salt type hydroxypropyl sodium sulfonate asphalt emulsifier is prepared from the following raw materials N-hydrogenated tallow-1,3-propylene diamine, an alcohol solvent, N-hydroxymethyl acrylamide, epichlorohydrin and sodium bisulfite according to a molar ratio of 1:(5.00-11.00):(3.00-3.10):(2.00-2.30):(2.10-2.50), and the alcohol solvent is ethanol, methanol or isopropanol. According to the present invention, the preparation method has advantages of easily available raw material, low production cost, simple process and no requirement of high temperature reaction; and the obtained secondary amide di-quaternary ammonium salt type hydroxypropyl sodium sulfonate asphalt emulsifier can emulsify a variety of different types of asphalts, and can be used for preparing cationic emulsified asphalts, and the emulsified asphalt prepared from the secondary amide di-quaternary ammonium salt type hydroxypropyl sodium sulfonate asphalt emulsifier has advantages of fine and uniform property and good storage stability.

Surface plasma resonance and mass spectrum combined device and application method thereof

The invention discloses a surface plasma resonance and mass spectrum combined device and an application method thereof. By the surface plasma resonance and mass spectrum combined device, real-time online combination of the surface plasma resonance technology and the mass spectrum technology is achieved in analytical chemistry. The surface plasma resonance and mass spectrum combined device is characterized in that a dielectric barrier discharge ion (DBDI) source is used as the ion source of a mass spectrometer, the DBDI source is placed at the front end of the inlet of the mass spectrometer, and the outlet of the DBDI source is allowed to face the inlet of the mass spectrometer; the analyzing solution of a surface plasma resonance instrument is introduced into a spray needle; the spray needle is arranged between the DBDI source and the inlet of the mass spectrometer, and a spray direction faces a DBDI source-mass spectrometer connecting line. When the surface plasma resonance and mass spectrum combined device works, the analyzing solution of the surface plasma resonance instrument is atomized by the spray needle, ionized by the DBDI source and introduced into the mass spectrometer for analysis, and surface plasma resonance data and mass spectrum data can be acquired at the same time in the same analysis.
