Fatty alcs. are known surfactants ubiquitous in the environment. They affect physicochem. and optical properties of aerosols and air/water interfaces; however, little is known about their photochem. Brown carbon (BrC) as photosensitizer, may initiate photochem. reactions of such non-photoactive surfactants. BrC was obtained by evaporating methylglyoxal/(NH4)2SO4 or methylglyoxal/glycine (Gly) mixtures The BrC photo-sensitization ability was evidenced by its reaction with 1-octanol under UV irradiation measured by attenuated total reflection Fourier transform IR spectrometry, a surface-sensitive technique. Condensed phase products were determined by gas chromatog./mass spectrometry. A series of functionalized, unsaturated compounds were formed by a photo-sensitized reaction; more highly oxygenated compounds appeared after a long illumination time. This process contributed to formation of reactive volatile and semi-volatile organic compounds and could also trigger secondary chem. The reaction was probably initiated by electronically excited BrC upon exposure to UV radiation. A possible mechanism for fatty alcs. photo-sensitized degradation is proposed. It was also observed that BrC was easily photo-bleached; thus, it has a limited effect on radiative forcing. However, BrC can play an important role in aerosol and air/water interfaces. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Recommanded Product: Octyl acetate).
Octyl acetate (cas: 112-14-1) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Recommanded Product: Octyl acetate
