Ethers lack the hydroxyl groups of alcohols. Without the strongly polarized O―H bond, ether molecules cannot engage in hydrogen bonding with each other. 111-90-0, formula is C6H14O3, Name is Diethylene Glycol Monoethyl Ether. Ethers do have nonbonding electron pairs on their oxygen atoms, however, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. Name: Diethylene Glycol Monoethyl Ether.
Ruokolainen, Joonas;Hyttinen, Marko;Sorvari, Jouni;Pasanen, Pertti research published 《 Exposure of cleaning workers to chemical agents and physical conditions in swimming pools and spas》, the research content is summarized as follows. Swimming pools and spas require a high hygiene level, and therefore constant cleaning. In this study, cleaning worker′s exposure to volatile organic compounds (VOCs), trichloramine (TCA), and particulate matter (PM) in the swimming pools and spas were evaluated. Also, statistical methods were employed to determine what activities affect the exposure to disinfection byproducts (DBPs). The study was conducted in 32 swimming pools and spas. The measurement locations were pool areas, bathrooms, and locker rooms, both during cleaning and opening hours. During the cleaning, the total volatile organic compound (TVOC) concentrations were low, on average 96, 251, and 91 μg/m3 for locker rooms, bathrooms, and pool areas, resp. Similarly, during the opening hours, the TVOC concentrations were on average 78, 125, and 83 μg/m3, for locker rooms, bathrooms, and pool areas, resp. This is in line with previous studies investigating cleaning work in other environments. The most prevalent compounds during the cleaning were 2-(2-butoxyethoxy)ethanol (DEGBE), 2-(2-ethoxyethoxy)ethanol (DEGEE), 2-butyl-1-octanol, trichloromethane (chloroform), decamethylcyclopentasiloxane (D5), and carbon tetrachloride. The most prevalent compounds during the opening hours were D5, D-limonene, carbon tetrachloride (bathrooms and pool areas), and trichloromethane (bathrooms and pool areas). The TCA concentrations during the cleaning in the bathrooms and pool areas were on average 60 and 67 μg/m3, resp., and during the opening hours, 28 and 122 μg/m3, resp. The use of disinfectants was found to increase the TCA concentration in the bathrooms, while the other cleaning products did not. Even though the TCA concentrations were below the WHO′s guideline and the Finnish occupational exposure limit value of 500 μg/m3, the measured TCA levels were occasionally high enough to pose a risk of irritative symptoms. The PM concentrations were low, both in the real-time monitoring (aerodynamic diameter, Dae ≤ 15 μm) and inhalable dust samples (Dae ≤ 100 μm). Highest measured inhalable dust concentration was 350 μg/m3, well below the Finnish occupational limit value of 5,000 μg/m3 for organic inhalable dust.
111-90-0, Diethylene glycol monoethyl ether appears as a colorless, slightly viscous liquid with a mild pleasant odor. Flash point near 190°F. Used to make soaps, dyes, and other chemicals.
Diethylene glycol monoethyl ether is a primary alcohol that is ethanol substituted by a 2-ethoxyethoxy group at position 2. It has a role as a protic solvent. It is a diether, a primary alcohol and a hydroxypolyether. It derives from a diethylene glycol., Name: Diethylene Glycol Monoethyl Ether
