: A new, simple method for the synthesis of N, N-dietyl-m-methylbenzamide (DEET) from m-toluic acid and diethylamine using 1,1'-carbonyl-di-(1,2,4-triazole) (CDT) as a coupling agent has been performed. The basic principles of activated carbonyls have been explored with the ability to prepare new amides easily. All reaction by-products are water-soluble as well as removed by filtration, the reaction could be purified easily in an aqueous solution by liquid-liquid extraction, and the product DEET was high purity. This experimental efficiency is about 94-95%, purity (HPLC): 97-98%.

Liquid Liquid Extraction

New method for determination of organochlorine pesticides (DDT and its metabolites, HCH and its isomers) is presented. The method includes a liquid-liquid extraction of pesticides under ultrasound and the substance analysis by gas-liquid chromatography. The degree of DDT and γ-HCH extracting from tissues of marine organisms is (78 ± 2) % and (91 ± 2) %, respectively. The total content of organochlorine pesticides in muscles of walleye pollock from the Okhotsk Sea is evaluated by this method in the range from 25 to 73 pg/g of lipids.
