[Spectral analysis of a compound in mould release agent of plastics].

This paper reported the structure of a main unknown compound which was isolated and purified by column chromatography from a new mould release agent used in plastics. Elemental analysis, infrared spectra and 1H nuclear magnetic resonance spectrum were used to study the structure characters. The structure was then confirmed by assigning infrared absorbing peaks and nuclear magnetic spectral bands of this compound and its hydrochloric acid-treated compound. It showed to be a surfactant, N,N-dihydroxyethyl dodecylamine. The result provides useful information for developing new mould release agents.
