The objective of this paper is to establish the method for rapid determination of 15 kinds of aromatic nitro compounds and phthalate esters in the workplace air. Various target mixtures in air collected by silicone tube and DB-35ms separation column and gas chromatog.-mass spectrometry are used in the determination and anal. of compounds after desorption by methanol. The results showed that all composition are completely separated, at the same time, qual. determination is performed. Fifteen kinds of mixture shows good linear relationship in certain concentration range, correlation coefficient (r) ≥ 0.990 0. The min. detection limit is far lower than the dosage level of occupational chem. poisoning position, desorption efficiency of 15 kinds of mixture is 92-97%. It was concluded that this method has high selectivity, sensitivity and accuracy, which can satisfy the rapid qual. and quant. determination of 15 kinds of nitro compounds and phthalate esters mixture in the workplace air. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Product Details of 5444-75-7).
2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Product Details of 5444-75-7
