Hot water as a mild Bronsted acid catalyst in ring opening reactions of epoxides

Ring opening of extremely hydrophobic epoxides with water, amines, sodium azide and thiophenol was realized in the mixture solvent of water and 1, 4-dioxane under reflux condition. Hot water was believed to act as a mild Bronsted acid catalyst in the epoxide-opening reactions.

Modified isocyanates

Modified stable polyisocyanates are described having at least one isocyanate function modified by a group having cross-linking functionality. The modified stable polyisocyanates may be prepared by reacting at least one polyisocyanate with a compound of the formula:

Synthesis and Characterization of Single-Chain Second Generation Cleavable Surfactants

Three series of single-chain, second generation cleavable surfactants, trans-trimethylammonium methanesulfonate (1) and sodium (2) and triethanolammonium trans-8-(2,2-dialkyl-5-octyl-1,3-dioxolan-4-yl)octane-1-sulfate (3) (a, R = Me; b, R = Et; c, R = Pr; d, R = Bu), were prepared.They were characterized by critical micelle concentration, Krafft temperature, and dynamic laser light scattering measurements.Acid-catalyzed hydrolysis of surfactants 1, 2, and 3 gives (threo-9,10-dihydroxyoctadecyl)trimethylammonium methanesulfonate (4) and sodium (6) and triethanolammonium threo-9,10-dihydroxyoctadecane-1-sulfate (7), respectively, and a dialkyl ketone 5 (a, Me2CO; b, Et2CO; c, Pr2CO; d, Bu2CO).Cleavage of these surfactants thus gives another surfactant, with a higher critical micelle concentration, and a water-soluble neutral compound.Surfactants 3 were about 20 times more reactive than 1.

Non-metal-requiring Catalyst Contained in Recovered Methyl Linolenate from an Autoxidizing Sample

Non-metal-requiring catalysts in recovered methyl lenolenate from an autoxidizing sample were unstable on contact with silicic acid and the activity varied widely with the way of recovery, countercurrent extraction and column chromatography under different conditions.After reduction with stannous chloride, a substance was found which was characteristically present in the products deriver from the recovered methyl linolenate high in the catalytic activity.It was tentatively indentified by MS, IR, OsO4 oxidation-IO41- oxidation, and LiAlH4 reduction-IO41- oxidation as methyl 9,13-dihydroxy-10-epoxy-15-octadecenoate.
