Preparation of Cationic Surface Active Agents from Higher Glycidyl Ethers

Solvent-Free Synthesis of Glycidyl Ethers Investigating Factors Influencing the Yield of Alkyl Glycidyl Ethers

Surfactants are a widely used group of chemicals. With a range of applications from soaps to paints and from hygiene products to asphalt they are one of the most diverse product groups available. AkzoNobel in Stenungsund uses glycidyl ethers as intermediates in the productions of some of their surfactants. These glycidyl ethers are produced with some hazardous compounds, which make the handling...

Cationic polymerization of glycidyl ethers and furans: improved electron beam and UV cured epoxy networks

Mutagenicity of aromatic glycidyl ethers with Salmonella.

6 aromatic glycidyl ethers containing naphthyl, biphenyl or benzylphenyl substituents were synthesized. These epoxides together with the commercially available compounds 2-biphenylyl glycidyl ether were examined for dose-mutagenicity relationships using the plate incorporation Ames test with Salmonella typhimurium strains TA100 and TA1535. Structure-mutagenicity relationships were further exami...

Enantioselective detoxication of optical isomers of glycidyl ethers.

The detoxication of the enantiomers of glycidyl 4-nitrophenyl ether (GNPE), (-)-(R)- and (+)-(S)-GNPE, and glycidyl 1-naphthyl ether (GNE), (-)-(R)- and (+)-(S)-GNE, by rat liver glutathione transferase and epoxide hydrolase was studied. Enantioselectivity was observed with both enzymes favoring the (R)-isomers as determined by the formation of conjugate, diol, and remaining substrate measured ...

Surface-active agents from two bacillus species.

Two Bacillus species were studied which produced bioemulsifiers; however, they were distinctly different compounds. Bacillus sp. strain IAF 343 produced unusually high yields of extracellular biosurfactant when grown on a medium containing only water-soluble substrates. The yield of 1 g/liter was appreciably better than those of most of the biosurfactants reported previously. This neutral lipid...
