Abstract:
A process for the preparation of a natural liquid fuel and, more particularly, a process that allows a high sulfur natural fuel to be converted into energy by combustion with a substantial reduction in sulfur oxide emissions.
Abstract:
Alkylated 5,6,7,8-tetrahydronaphthalenols are effective antioxidants for fuel oils, lubricating oils, greases, plastics, and rubbers over a wide temperature range. Di- and tri-alkylated tetrahydronaphthalenols are especially effective, with the di- and tri-isopropylated materials being preferred.
Abstract:
Organic material is stabilized against oxidative degradation by the addition of a small amount of an antioxidant compound or mixture of compounds containing a central segment of one to about ten divalent o-hydrocarbyl phenyl groups (e.g. o-tert-butylphenol) bonded to each other through a methylene group and having terminal 3,5-dihydrocarbyl-4-hydroxybenzyl groups at each end. They are made by first condensing o-hydrocarbyl phenol with formaldehyde and then reacting the intermediate with 2,6-dihydrocarbyl phenol and formaldehyde.
Abstract:
Para hydrocarbyl-substituted phenol or thiophenol dicarboxylic acids as anti-rust and anti-corrosion additives to liquid hydrocarbon fuels and lubricants.
Abstract:
THE NOVEL COMPOUND, 5,7-DIISOPROPYL-1,1-DIMETHYL-6HYDDROXYINDAN, (I), AND A PROCESS FOR PREPARING IT, ARE DISCLOSED. I IS A COLORLESS CRYSTALLINE MATERIAL, M.P. 99*100*C., AND HAS A STRONG AND PLEASANT MUSK ODOR, I IS SUITABLE FOR USE IN PERFUMERY. I ALSO EXHIBITS PROPERTIES AS AN ANTIOXIDANT. I IS PREPARED BY REACTING 2,6-DIIOPROPYLPHENOL AND ISOPRENE, IN THE PRESENCE OF SULFURIC ACID OR OTHER ALKYLATING CATALYSTS; AT TEMPERATURES FROM -20* TO 150*C., DEPENDING ON THE STRENGTH OF THE CATALYST.
Abstract:
Organic compositions are provided containing secondary C6 to C9 trialkyl phenols, or their mixtures, as antioxidants for preventing oxidative deterioration of metal surfaces.
