We have developed a liquid chromatography and dual wavelength UV–Vis spectrometry method for determination of N–nitrosodiethanolamine NDELA in coconut diethanolamide. The sample is diluted with methanol and injected to the HPLC.ODS column is performed and a mixture of methanol and water is selected as mobile phase . dual wavelength in UV–Vis detector is used because of decrease effects of complex matrix on the chromatograms.<\div>

Benzalkonium chloride is a cationic surfactant that is used as a controller of biocorrosion and enhanced oil extraction through de–emulsification and sludge breaking in oil and gas industries. The common industrial method for synthesis of this compound is the reaction of benzyl chloride withdimethyl lauramine, but reported methods are hard and unsuitable for industrial synthesis. In this article optimized condition for synthesis of this compound and analytical methods of raw material and product is reported<\div>
