Abstract:
     In this invention, orthobutanol, potassium (or sodium) bromide, H2SO4 are used as raw materials to generate orthobrombutane, and the orthobrombutane (or benzyl chloride) and caprolactam as raw material, KOH (or NaOH) as alkali, toluene as solvent, PEG as catalyst to complete the synthesis in two step under heating condition. The process features simple operation, short reaction period, higher yield rate and lower cost. The synthesized compound is a new synergist to promote penetration.
